So the whole year of 2022 got pear-shaped and many of my plans had be cancelled. I had a small procedure at the end of the year--on the day before Thanksgiving exactly-- and this made the year of 2023 a year of recovery.</p><p>The year of recovery meant I was going to try to do three trips (since I had to cancel many in 2022): one simply to Chapman, South California, one to Bloomington, Indiana and one to Pisa and Padova, in Italy. All of them went well, mostly: I got covid when returning from Indiana. So I decided to do another three trips: to St. Louis, Missouri, to Dagstuhl, Germany and to Pasadena, CA.</p><p>The one I was most worried about was the one to Dagstuhl, as I do not speak German and Dagstuhl can be fairly inaccessible. But I partnered with Jacques Carrette and Stefania Dumbrova and all went well getting there and getting back home. And being at Dagstuhl is always a pleasure! I have met several people who, like me, are concerned about using digital tools to make mathematics more accessible.</p><p>The schedule of the talks and discussions is in https://www.dagstuhl.de/23401/schedule.pdf. I really need to read a bit more about some of the work that I did not manage to grasp while there.<br /></p>Valeriahttp://www.blogger.com/profile/01336528462208811726noreply@blogger.com0tag:blogger.com,1999:blog-4249190426304084757.post-61644856343147891792024-02-27T12:03:00.000-08:002024-02-27T12:34:50.952-08:00Preparing for Network Mathematics 2023<p> </p><p> </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitnF1SWM_l8rUP3uN6Bf_1xBT1dATW4acTgebNbox5FpV94jLAuOq23-CFcI8iF8CPknZ1i6NTzmylJBhQqa34aWkDUfKlrPrP_SO1Nwv0LQDiwPGpEjmecvktGnUiFIH6Mgf3jjOPdCEdG-ASXoaLktmgN_RkIEh4TtoSwoEw1QQ5QYjnLjctw1NUkps/s2754/StonehengeFeb2024.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1628" data-original-width="2754" height="378" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitnF1SWM_l8rUP3uN6Bf_1xBT1dATW4acTgebNbox5FpV94jLAuOq23-CFcI8iF8CPknZ1i6NTzmylJBhQqa34aWkDUfKlrPrP_SO1Nwv0LQDiwPGpEjmecvktGnUiFIH6Mgf3jjOPdCEdG-ASXoaLktmgN_RkIEh4TtoSwoEw1QQ5QYjnLjctw1NUkps/w640-h378/StonehengeFeb2024.png" width="640" /></a></div>(source: Twitter/X account Stonehenge UK)<p></p><p><br />This post is a continuation of <a href="https://topos.site/blog/2023-01-05-preparing-for-networked-mathematics/index.html"><span style="font-size: small;">Preparing for Networked Mathematics</span></a><span style="font-size: small;">.</span></p><p></p><p>During 2023 we had a few more talks on theorem provers and automated deduction.

Yes, Ada Lovelace Day (ALD) is in October, and it varies a little each year, a convenient leeway, for chronically late people, like myself. This year I have less of an excuse, as I had decided to honour Andrée in July already. But the year was hectic, in a good way, so I didn't get around to posting my ALD "hommage" so far. But today is the last day of the year, so here it goes, before the clock chimes, and we change back into pumpkins.</p><p>Andrée has been a role model for me in many ways. She's been a mathematician for longer than I have been alive, and I am very old indeed. She has this awesome description of her research work in her <a href="https://mes-ehres.fr/indexAE.htm" target="_blank">webpage</a>.

Like today's post, that one was hastily written, rushing to some function or something else.

So I could write lots about Andrée's work, but you can look at her pages, the "Cahiers" work for more than 40 years, and the lovely diagram above. So I'd rather leave you with Marta's words in 2016 and a picture of Marta, since I have not mourned her absence enough. The volume celebrating her work is now almost totally ready, so I will be writing more about Marta soon.

an unfair situation, which I believe. I hope that someone more
qualified than I can do this since I believe it is important for our

someone who has done a lot for our field - not just by continuing the
work of Charles Ehresmann by publishing his Oeuvres Completes and
continuing with the journal Cahiers de Topologie et Geometrie
Differentielle (Categoriques), but by encouraging many researchers in
our field - both men and women. She certainly deserves mention as a

Considering that we never had grants to help us defray costs of the workshop, I think getting to our seventh anniversary is a big milestone. Everyone who works for Women in Logic does it for free and because they find the cause important. You may be wondering, “what is Women in Logic?”</p><p style="margin: 15px 0px 25px; text-align: justify;">Women, like some other demographics groups, are very badly represented in STEM (Science, Technology, Engineering and Mathematics) subjects. While on paper we have the right to be part of our STEM communities, in reality the obstacles are very strong and sometimes even insurmountable for women participation in Academia. The infamous “<a href="https://en.wikipedia.org/wiki/Glass_ceiling" style="background: transparent; color: #007481;">glass ceiling</a>” is still very much with us and many of our colleagues do not notice it. (ha, this is why it’s called a “glass” ceiling, right?) Even the colleagues that are notionally aware of the issues, many times do not see them, when they happen in their own lives. The sexism in STEM is systemic and entrenched, it affects both men and women. And it is not a small action like WiL that will defeat it, but WiL does help, a little, to shed some light on some of the issues.</p><p style="margin: 15px 0px 25px; text-align: justify;">Women in Logic (WiL) started for me in 2013, when<span> </span><a href="https://www.cs.huji.ac.il/~ornak/" style="background: transparent; color: #007481;">Orna Kupferman</a>, who was the Program Chair of LICS that year, presented her LICS chair findings and showed this slide:</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEju_eDFPfVOYkcEMOPZSsg-ti14QLfXhCwx6McA_U3rQRw8jGo6qjnlDbM6-v1TSuGsyK0m3FK6b2z-msupxOb-xz2g3msZ9Ww5NrRwYUc8VKYMkS4i5dqme2Sncx02mxImG_3TkWOHOusm5DmW7ierAiKafyCSpdOVdT4ceIIV0UUsx6uyYrEIxblJLZc/s1500/lics2013-orna.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1125" data-original-width="1500" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEju_eDFPfVOYkcEMOPZSsg-ti14QLfXhCwx6McA_U3rQRw8jGo6qjnlDbM6-v1TSuGsyK0m3FK6b2z-msupxOb-xz2g3msZ9Ww5NrRwYUc8VKYMkS4i5dqme2Sncx02mxImG_3TkWOHOusm5DmW7ierAiKafyCSpdOVdT4ceIIV0UUsx6uyYrEIxblJLZc/s320/lics2013-orna.jpg" width="320" /></a></div><p style="margin: 15px 0px 25px; text-align: justify;">Until then, while I knew about all the prevalent sexism in society, (it’s hard to ignore the many manifestations, from murdered women to silenced ones) I thought that my community was a bit better than most. My colleagues seemed to me more helpful and more enlightened. Thus when I saw the numbers, it was a shock: how come there were no awards for women? How come there were no women on the advisory board(*)? how come only 3.7% of the submissions in 2013 were by women? It all did seem TERRIBLE!</p><p style="margin: 15px 0px 25px; text-align: justify;">Much more disturbing was the discovery that, despite many efforts, things were not getting better, they were even getting worse! A representative graph was provided by the AAUW (American Association of University Women) in their report entitled “<a href="https://www.aauw.org/app/uploads/2020/03/Solving-the-Equation-report-nsa.pdf" style="background: transparent; color: #007481;">Solving the Equation</a>”, 159 pages of dismaying facts. As you can see below, while the numbers of women in Mathematics and Computer Science improved from 1960 till around 1990, from then on they dropped, being in 2013 lower than they were in 1960! Engineering, traditionally considered one of the worst areas for women, at least has increasing numbers, but from 9% in 1990 to 12% in 2013. This is a minuscule improvement, leading to, in general, the prediction that at the current rate of progress, the pay gap will not close until 2111.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiUlZVY5FkmNwFYvT8DACoVIZN8IHqQP49CjFIusQDsvsqPewX1NNCs8kxI0cCbni2546-6eOynro6JZR7z576xj3QrjGtLysQwXZNgTKHosdghLIWuSmIt3ng54P3n_ki7v9MeBNEintiT9N820lB31qKM2wswkrFQPgM5oHvGgNwrHXpf4xbWR30VJso/s644/AAUW2015.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="440" data-original-width="644" height="274" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiUlZVY5FkmNwFYvT8DACoVIZN8IHqQP49CjFIusQDsvsqPewX1NNCs8kxI0cCbni2546-6eOynro6JZR7z576xj3QrjGtLysQwXZNgTKHosdghLIWuSmIt3ng54P3n_ki7v9MeBNEintiT9N820lB31qKM2wswkrFQPgM5oHvGgNwrHXpf4xbWR30VJso/w400-h274/AAUW2015.png" width="400" /></a></div><p style="margin: 15px 0px 25px; text-align: justify;">So I started to think about how to do something about this sad state of affairs.

It was easy to find several friends who wanted to do this too, so our collective was formed.</p><p style="margin: 15px 0px 25px; text-align: justify;">Since then the Workshop has occurred in<span> </span><a href="https://sites.google.com/site/womeninlogic2018/welcome" style="background: transparent; color: #007481;">Oxford 2018 (UK)</a>,<span> </span><a href="https://sites.google.com/site/womeninlogic2019/home" style="background: transparent; color: #007481;">Vancouver 2019 (CA)</a>,<span> </span><a href="https://sites.google.com/g.uporto.pt/wil2020" style="background: transparent; color: #007481;">Paris 2020 (online)</a>,<span> </span><a href="https://sites.google.com/g.uporto.pt/wil2021" style="background: transparent; color: #007481;">Rome 2021 (online)</a><span> </span>and<span> </span><a href="https://sites.google.com/g.uporto.pt/wil2021" style="background: transparent; color: #007481;">Haifa, 2022 (Israel)</a>. By most accounts the workshops have been very successful. The invited speakers, so far always two in each workshop, have been excellent and they showcased many different facets of logic in computing, mathematics and philosophy: from Software Engineering to Automated Reasoning to Computational Biology and Artificial Intelligence.</p><p style="margin: 15px 0px 25px; text-align: justify;">We have received some small grants from the Special Interest Group of the ACM for Logic (<a href="https://siglog.acm.org/" style="background: transparent; color: #007481;">SIGLOG</a>), the Vienna Center for Logic and Algorithms (<a href="http://www.vcla.at/" style="background: transparent; color: #007481;">VCLA</a>), the Institute of Logic, Language and Computation of the University of Amsterdam (<a href="https://www.illc.uva.nl/" style="background: transparent; color: #007481;">ILLC</a>).These allowed us to help students and young researchers attend our workshop.

Many thanks are due to, especially Juliet Szatko and Tim Hosgood, for all the help provided!</p><p style="margin: 15px 0px 25px; text-align: justify;">After the worst (we hope) of the COVID19 pandemic, we are now in the process of restructuring and rethinking how to make the collective Women in Logic more efficient. We have several social media channels, managed by several members of the original group.

Baez blogged about it in “<a href="https://golem.ph.utexas.edu/category/2021/10/learn_applied_category_theory.html">Learn Applied Category

Here’s a poster advertising the whole program.</p>

<p>We also had a paper in the Notices of American Mathematical Society,
describing our proposal:</p>
<blockquote>
<p><a href="https://math.ucr.edu/home/baez/mrc_2022.pdf">Applied Category Theory in Chemistry, Computing, and Social Networks</a>

</blockquote>
<p>An MRC is a bit like a version “on steroids” of the
<a href="https://adjointschool.com/about.html">ACT Adjoint School</a>, as there are many
more researchers in a research subgroup in the MRC than in a Adjoint
School group. While my ACT Adjoint School group had four students and a
TA, my MRC group had thirteen researchers. So from four to thirteen
people you have more than three times the number of people to do
interesting research with. Plenty of fun, but it can be unsettling to
think about research problems for so many people you don’t know,
especially for me (well, I haven’t had that much experience directing
other people’s research).</p>
<p>I was very worried to begin with, but when we got going, it was
exhilarating. Great fun to discuss serious math problems with people
interested in similar problems, with similar tastes to yours and with
plenty of ideas of their own. The program had three mentors (John, Nina
and myself), and I ended up with a group of 13, subdivided into 4
smaller groups. Things were going very well (you can check some of the
discussions in the Zulip channel <a href="https://categorytheory.zulipchat.com/#narrow/stream/323208-practice.3A-Dialectica/t"><code>[practice:Dialectica]</code></a>)
until two days before the meeting in upper New York state I got ill, and
ended up in the ER in the Stanford hospital. Twice.</p>
<p>I couldn’t go to the research meeting in Beaver Hollow, but
<a href="https://scholar.google.com/citations?hl=en&user=sPcB8qAAAAAJ&view_op=list_works&sortby=pubdate">Jérémie Koenig</a>,
my trusted deputy, managed to get everyone working well together into
the four groups we had established before:</p>

<p>The neat thing about MRCs is that they give the participants some funds
to make academic visits and I was very touched when my group decided to
come and visit me in California, using their funds. This meant that we
had another smaller meeting in Cupertino, in the middle of the Summer.
Well, it was already September and usually the weather over here is good
most of the time, but we had some bad luck, and this week was a
heatwave, the worst one this summer. But we had some fun. Now the
problem is reworking what happened in the many discussions.</p>
<p>A third component of the MRC program is still to come. Of course we all
hope that the math we discussed during the summer will mature nicely
into preprints and papers and programs, and these are supposed to be
presented in the
<a href="https://www.jointmathematicsmeetings.org//jmm">AMS Joint Mathematics Meetings</a>
(JMM) in Boston in early January. So one organizer was chosen from each
mentor’s group and I am very happy that
<a href="https://aten.cool/">Charlotte Aten</a>
accepted to be the organizer for our group, despite being in the last
weeks of her PhD and interviewing for jobs. Then sometime in September
we were told everyone needed to write up some ideas that they hoped
could make solid papers before January 2023. I’m glad to report that
every one of our four subgroups was able to produce an abstract and I
hope the papers are in the process of being written as I write this.</p>
<p>Now this post was meant to be about the four subgroups above and why I
am so excited for the mathematics we’re doing. But I am a bit behind
with my processing of the knowledge we shared when people visited here
(and over Zulip!). So, while I could possibly wait for the JMM to get to
grips with more of the new math that people are producing, I think I
will try to explain, at least a little, how the themes above interact.</p>
<p>I started my research career working on Gödel’s Dialectica
Interpretation. On bad days I think not only have I never left the
dialectica, but even today I hardly understand the stuff, after all
these many years. Then I console myself with the thought that the stuff
is really fascinating and full of surprising consequences and
applications!</p>
<p>Someone else who’s awed by the Dialectica Interpretation is Jules
Hedges. His blog post
<a href="https://julesh.com/2018/08/16/lenses-for-philosophers/">Lenses for Philosophers</a>
shows some of the badly understood consequences and connections of the
work on categorical dialectica construction. In some ways the MRC
<i>Dialectica categories for Computing</i> is an attempt to clarify some of
the interrelations described in Hedges’ post.</p>
<p><a href="https://en.wikipedia.org/wiki/Dialectica_interpretation">Gödel’s Dialectica Interpretation</a>
is a proof interpretation of
intuitionistic arithmetic into a quantifier-free theory of functionals
of finite type, called <i>System T</i>.</p>
<p>The interpretation’s original use was to show the consistency of Heyting
(or intuitionistic) arithmetic. When combined with Gödel’s double-negation
interpretation, which reduces classical arithmetic to intuitionistic
arithmetic, the Dialectica interpretation yields a reduction of the
classical theory as well.</p>
<p>As explained by
<a href="https://webpages.ciencias.ulisboa.pt/~fjferreira/dialectica_ff_web.pdf">Fernando Ferreira</a>,</p>
<blockquote>
<p><i>The stated purpose of Gödel’s Dialectica paper is to present a</i>
<i>consistency proof of first-order Peano arithmetic PA by way of an</i>
<i>extension of the finitary viewpoint according to which the requirement</i>
<i>that constructions must be of and over “concrete” objects is relaxed to</i>
<i>be of and over certain abstracta, namely computable functionals of</i>
<i>finite type over the natural numbers.</i></p>
</blockquote>
<p>Thus the Dialectica
interpretation can be considered a relaxed (or liberalized) form of
Hilbert’s program, where instead of insisting on the finitary viewpoint,
we accept ‘computable functionals of finite type’ as (sort-of)
concrete objects. To understand the interpretation itself, I recommend
A.S. Troelstra’s “Introductory Note to the Dialectica paper” in
<a href="https://monoskop.org/images/b/b7/Kurt_Godel_Collected_Works_Volume_II_1989.pdf">Gödel’s Collected works, volume II</a>,
where we can read that “Gödel presents his results as a contribution to a
liberalized version of Hilbert’s program: to justify classical systems,
in particular arithmetic, in terms of notions as intuitively clear as
possible.” From there one can graduate to more complete work of
Troelstra himself
(<a href="https://link.springer.com/book/10.1007/BFb0066739">Metamathematical investigation of intuitionistic arithmetic and analysis</a>
(1973)), of Avigad and Feferman
(<a href="https://www.andrew.cmu.edu/user/avigad/Papers/dialect.pdf">Godel’s Functional (“Dialectica”) Interpretation</a>)
and of
<a href="https://link.springer.com/book/10.1007/978-3-540-77533-1">Kohlenbach</a>
and his school.</p>
<p>The categorical internal versions of the Dialectica construction,
starting in de Paiva’s thesis in 1988 (out as a
<a href="https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-213.pdf">technical report</a>
in 1991), have spelled out some of the requirements and consequences of
the interpretation, especially its connection to Linear Logic. The
categorical dialectica construction was generalized to fibrations, by
<a href="https://www.dpmms.cam.ac.uk/~martin/Research/Publications/2002/pta02.pdf">Hyland</a>
(2002),
<a href="https://cs.au.dk/~birke/phd-students/BieringB-thesis.pdf">Biering</a>
(2008) and
<a href="https://mysite.science.uottawa.ca/phofstra/dialectica.pdf">Hofstra</a>
(2011). Generalizations to dependent type theories appeared in
<a href="https://www.repository.cam.ac.uk/handle/1810/254394">van Glehn</a>
(2016) and
<a href="https://www.repository.cam.ac.uk/handle/1810/280672">Moss</a>
(2018) and then
<a href="https://arxiv.org/abs/2105.00283">together</a>
(2018). More recently Trotta et al, building on this work introduced
<a href="https://arxiv.org/abs/2104.14021">Gödel fibrations</a>
and
<a href="https://arxiv.org/abs/2205.07093">Gödel doctrines</a>,
rekindling the
connections of the categorical dialectica construction to logic and
making sure that the three dialectica principles (Independence of
Premise, Markov Principle and Axiom of Choice) get their categorical
explanation.</p>

<p>The main connections of the Dialectica construction discussed in the
MRC, as anticipated above, are between ‘lenses’ and dialectica
categories, between ‘polynomials’ and dialectica categories (see Nelson
Niu’s
<a href="https://topos.site/blog/2022/07/dialectica-categories-and-polynomial-functors-part-1/">blog post</a>
and Sean Moss’
<a href="https://www.youtube.com/watch?v=tw08TmO0RRo&t=7190s">talk</a>),
between ‘games’ and dialectica categories (already hinted at in
<a href="https://www.sciencedirect.com/science/article/pii/0168007292900739">Blass’ original paper</a>
on games for linear logic) and between concurrency theories and
dialectica categories in the shape of
<a href="https://arxiv.org/pdf/2105.12801">Dialectica Petri nets</a>
Processes and their
implementation in Agda. I hope the abstracts for the extended
discussions of these four sets of connections will be available soon.</p>
<p>But it is clear that we’re only scratching the surface of this rich
story of interconnections. Hopefully much more will come to light in the
near future.</p>

<p>Humans are very good at recognizing the words they do not know, the concepts
they haven’t met yet. To help with these they invented dictionaries,
glossaries, encyclopedias, wikipedias, crib sheets, etc. Initially, they did it
via laborious manual work, more recently through automated construction
techniques. Natural language processing (NLP) tools have improved impressively
in the last decade. Most of this incredible improvement happened to newspaper
text and hence named entities of the kind found in news text can be detected
and classified (usually into people, organizations, places and dates) with much
greater accuracy than in the recent past.</p>

<p>However, for domain specific text, like the academic literature in different
sciences (e.g. Medicine, Biology, Chemistry), or in the Humanities
(History, Sociology, Philosophy, etc.) things are more complicated. Thus
extracting technical terms/concepts from papers is important, interesting and
usually difficult.</p>
<p>How do you detect mathematical concepts in text? As a human mathematician
(or not), you probably recognize that the ovals in the snippet in this picture
correspond to mathematical concepts. But there is some uncertainty in this
choice, and several metrics might be used to decide whether the automated
system used is getting it right or not.</p>

<p>We wanted to see how well ‘automatic term extractors’ (ATE) systems work for
mathematical text, especially for Category Theory, if we simply use
them <i>out-the-box</i>. It seems reasonable to establish baselines using
available, open source systems and this is what we do in our paper
“<a href="https://arxiv.org/abs/2208.13830">Extracting Mathematical Concepts from Text</a>”.
The paper was presented at the
<a href="http://noisy-text.github.io/2022/">8th Workshop on Noisy User-generated Text (W-NUT)</a>
at Coling 2022 and you can find a short, technical video describing the work
below.</p>
<p>This work is part of a larger project on Networked Mathematics that we started
describing in
“<a href="https://topos.site/blog/2021/07/introducing-the-mathfoldr-project/">Introducing the MathFoldr Project</a>”
and broadened the discussion in
“<a href="https://topos.site/blog/2022/04/the-many-facets-of-networked-mathematics/">The many facets of Networked Mathematics</a>”.
We hope to provide more information on the project soon.</p>

text-align: justify;">Last year<span> </span><a href="https://topos.site/blog/2021/07/introducing-the-mathfoldr-project" style="background: transparent; color: #007481;">we started a discussion</a><span> </span>on the production of mathematics, the pre-industrial kind of process that we all still follow of solving problems and taking the solutions to the market of ideas (conferences, seminars, blog posts, twitter, coffee breaks in the department, etc.) as drafts/preprints/submissions and all the difficulties that this process involves. In particular we discussed the difficulties of checking whether the work had been done before or not, and the difficulties of searching for other, similar work that might help us with a given question.</p><p style="margin: 15px 0px 25px; text-align: justify;">As a group we settle on a path of trying to apply the new tools of NLP and knowledge representation (neural nets, word embeddings, transformers, ontologies, semantic web tools, etc.) to what might be called <b>mathematical English</b>. We reasoned that, yes eventually we will need to get to the semantics of equations and diagrams, but it would be useful to know how much we can learn simply from using the tools of NLP to extract mathematical concepts from abstracts of articles.</p><p style="margin: 15px 0px 25px; text-align: justify;">We also decided that Category Theory would be our prototype domain. First because category theory is about the organization of Mathematics in general, discovering the backbones of the subject and the hidden similarities between, in principle, unrelated sub-areas. But secondly because we are category theorists, after all. So this is the domain in which we are domain experts.</p><p style="margin: 15px 0px 25px; text-align: justify;">We realized early on that corpora of mathematical text were needed, and we hoped this wouldn’t be a problem. Category theory was, after all, one of the first areas of Mathematics to have a free open-source journal, namely TAC (<a href="http://www.tac.mta.ca/tac/" style="background: transparent; color: #007481;">Theory and Applications of Categories</a>) in 1995. But we need much more data than simply one journal. While we also have both the <a href="https://ncatlab.org/nlab/show/HomePage">nLab</a> and the whole of the<span> </span><a href="https://en.wikipedia.org/wiki/Portal:Mathematics" style="background: transparent; color: #007481;">Wikipedia Math Portal</a>, as beautiful mathematical open resources, even the licensing of the <a href="https://arxiv.org/">arXiv</a> is more problematic than we knew.</p><p style="margin: 15px 0px 25px; text-align: justify;">As we explained in the<span> </span><a href="https://topos.site/blog/2021/07/introducing-the-mathfoldr-project/" style="background: transparent; color: #007481;">earlier blog post</a>, we have chosen to work with a corpus of TAC abstracts and one (snapshot) of the nLab from the beginning of 2021. The TAC abstracts are clean, with not so much LaTex thrown in, and form a small corpus of 3.2K sentences. The nLab is a bit more noisy, one needs to remove the wiki markup and sections and headings get lost, a traditional nightmare of processing scientific text.</p><p style="margin: 15px 0px 25px; text-align: justify;">We now have<span> </span><a href="https://spacy.io/" style="background: transparent; color: #007481;">spaCy</a><span> </span>processing of all this data, as well as a collection of experiments on term extraction, using different tools:<span> </span><a href="https://pypi.org/project/pytextrank/" style="background: transparent; color: #007481;">TextRank</a>,<span> </span><a href="https://github.com/wetneb/opentapioca" style="background: transparent; color: #007481;">OpenTapioca</a>,<span> </span><a href="https://github.com/dwadden/dygiepp" style="background: transparent; color: #007481;">DyGIE++</a><span> </span>and Parmenides, a special tool of our NIST collaborators. There are plenty of interesting observations to make about the processing and the comparison between these tools, and we <strike>are preparing</strike> have now a write-up about it. However, the major problem with domain specific NLP strikes again: we have no <b>golden standard</b> for mathematical concepts in mathematical texts, much less for category theory concepts. Our predicament is not only ours: many others have the same issue and have tried to make do with <b>not</b> guaranteed good results. </p><p style="margin: 15px 0px 25px; text-align: justify;">Meanwhile, we have been working on the idea that formalized mathematics will eventually be the way of producing mathematics, which is a new kettle of fish altogether. To discuss the issues of formalization (somewhat an eventual goal) we have had in the Topos Colloquium talks by several people involved with automated deduction:<span> </span><a href="https://www.youtube.com/watch?v=Kpa8cCUZLms" style="background: transparent; color: #007481;">Jeremy Avigad</a>,<span> </span><a href="https://www.youtube.com/watch?v=alByz_LoANE" style="background: transparent; color: #007481;">Kevin Buzzard</a>,<span> </span><a href="https://www.youtube.com/watch?v=tYqbbRsx8DI" style="background: transparent; color: #007481;">Larry Paulson</a>,<span> </span><a href="https://www.youtube.com/watch?v=uJ3psQ-Dkpw" style="background: transparent; color: #007481;">Florian Rabe</a>, for example.

This workshop is usually associated with one of the big conferences in logic for Computer Science, so either FLoC (Federated Logic conference), LiCS (Logic in Computer Science) or FSCD (Conference on Formal Structures for Computation and Deduction), so far. The workshop has happened in Reykjavík (Iceland), Oxford (UK), Vancouver (Canada), Paris (online due to covid) and Rome (online due to covid). The next workshop <strike>should be happening</strike> happened in Haifa, Israel, as part of FLoC, on July 31st, 2022.</p><p style="margin: 15px 0px 25px; text-align: justify;">Women are chronically underrepresented in the Logic communities in Computer Science, in Philosophy, in Cognitive Science and in Mathematics; consequently they sometimes feel both conspicuous and isolated, and hence there is a risk that the under-representation is self-perpetuating. The WiL workshops provide an opportunity for women to increase awareness of one another and one another’s work, to combat the feelings of isolation. It provides an environment where women can present to an audience comprising mostly women, replicating the experience that most men have at most CS meetings, and lowering the stress of the occasion; we hope that this will be particularly attractive to early-career women.</p><p style="margin: 15px 0px 25px; text-align: justify;">The workshop Women in Logic (WiL) is supported by small grants provided by ACM’s<span> </span><a href="https://siglog.acm.org/" style="background: transparent; color: #007481;">SIGLOG</a>, the<span> </span><a href="http://www.vcla.at/" style="background: transparent; color: #007481;">Vienna Center for Logic and Algorithms</a>, the<span> </span><a href="https://www.google.com/url?q=https%3A%2F%2Fwww.illc.uva.nl%2F&sa=D&sntz=1&usg=AFQjCNHrprRi0n3Z_iw5D2roUZ13nwlTqg" style="background: transparent; color: #007481;">Institute of Logic, Language and Computation of the University of Amsterdam</a><span> </span>and the<span> </span><a href="https://topos.institute/" style="background: transparent; color: #007481;">Topos Institute</a>.

Hence, I've decided to duplicate here my blogposts in the Topos blog. At Topos, I have to follow a style that sometimes clashes with mine, while here I can do things my own way. And this is a huge plus. </p><p>Below you can see what was the blog post we wrote about our MathFoldr project 17 months ago. Much can happen in 17 months, but also much can not happen. Despite a very enthusiastic response from our ACT community, we were not able to convince the funding agencies that this is an important project. Thus, the work was carried on, but at a slow pace.

A group of physicists discovered a useful identity relating eigenvectors and eigenvalues, and did not know if it was novel. To check, they emailed a number of mathematicians, including Fields Medallist Terence Tao. Despite believing the result was “so short and simple—it should have been in textbooks already”, Tao had not previously heard of it. This led to a paper submitted for publication and, soon after, the article in Quanta. In the weeks after the story emerged, more than<span> </span><em>three dozen</em><span> </span>previously published instances of the result were reported, dating back to 1934.<span> </span><em>How can it be that even eminent mathematicians cannot find a widely published, basic result within their field of expertise?</em></p><p style="margin: 15px 0px 25px; text-align: justify;">The simple answer is that the mathematical literature has grown far too vast for even an expert to keep track of it all.

Veronica was a wonderful friend, a person one could count on, for real. One who did not complain about things in life, and it was always ready for a lunch, a book discussion, a woman's march and/or anything else she thought was important. <p></p><p>You really had to know her very well to realize she was fighting a cancer for many years. She was a true engineer, very proud of her work on improving performance of systems (at Samsung), but she rarely talked to us about her work. We have a women's lunch, the BWITCH (something like `Brazilian Women in Tech' lunch), which, like so many of these meetings, sometimes increased, sometimes waned a bit, depending on how busy people were. Lately, we were in a not-so-active phase, after many zoom meetings over the pandemic. And I thought everything was getting better for Veronica's health, I really don't know where I find this misplaced optimism of mine. </p><p>On Sunday there was a memorial for her, and many people discovered many facets of Veronica's personality that we knew nothing about, like I learned that she did martial arts! The hiker, the pottery artist, the devoted wife and mother, the woman committed to improving society I knew well, but there were many other sides that I knew nothing about. I used to tease her quite a bit about being an engineer thru and thru and in the last weeks I had been planning to talk to her about persimmons. We have a persimmon tree and we don't like the fruit, which Veronica likes, so I always write to her to come and collect some, which she organizes carefully to make sure they finish ripening at the right time, in the right way. This year the fruit is ready to be picked up much earlier than usual, and I had been meaning to write her for a while saying it, when the horrible news arrived that she was in a coma. Some days later she was gone. I did not manage to say goodbye. So I'm saying it here: Rest in power, Veronica!</p><p><br /></p>Valeriahttp://www.blogger.com/profile/01336528462208811726noreply@blogger.com0tag:blogger.com,1999:blog-4249190426304084757.post-40385735915807807632022-10-22T08:07:00.003-07:002023-02-07T09:43:22.367-08:00Ada Lovelace Day 2022: Bertha Lutz<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQtHCgrRClwHsBbfUfVs3dZR69WvvgKVXB5SeNu_SY5rNc0rekDbEMLDmU4--uNCRUL9xyxJSmQDNbYnD44YiswSs325oQoHPzP3cMAMhH6du9KQRxJqK9r_d23BN8AAqlszxjI9BgzCz3-nUPs-knLoudpNTdt-pV0wsAvMDMAXTgNrA04DyJm3yP/s1919/Primeiras_eleitoras_do_Brasil.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1361" data-original-width="1919" height="284" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQtHCgrRClwHsBbfUfVs3dZR69WvvgKVXB5SeNu_SY5rNc0rekDbEMLDmU4--uNCRUL9xyxJSmQDNbYnD44YiswSs325oQoHPzP3cMAMhH6du9KQRxJqK9r_d23BN8AAqlszxjI9BgzCz3-nUPs-knLoudpNTdt-pV0wsAvMDMAXTgNrA04DyJm3yP/w400-h284/Primeiras_eleitoras_do_Brasil.jpg" width="400" /></a></div><br /> This is a year of politics in Brazil. The election for President of the Republic is going on at the moment, we had the first turn, the second turn of voting is within a week. It occurred to me that I don't know much about the feminist movement in Brazil. I don't know enough about History, and I wish I did. So this blog post is about when voting for women started in Brazil.<p></p><p>The state of Rio Grande do Norte was a pioneer in providing in 1926, in its Electoral Law, that "all citizens who meet the conditions required by law may vote and be voted on, without distinction of sex." The following year, Celina Guimarães Viana became the first female voter in the country and, in April 1928, the first woman to vote.</p><p></p><p>In 1929, Alzira Soriano won 60% of the votes and on January 1 of the following year she was sworn in as mayor of Lajes, in Rio Grande do Norte. She was the first woman in Latin America to assume the government of a city. It was only in 1932, during the government of Getúlio Vargas, that women gained the right to vote and were able to run for political office. In 1933, Carlota Pereira de Queirós became the first Brazilian federal deputy from São Paulo.</p><p>But the post is about Bertha Lutz because she was a scientist, a biologist. <br /></p><p>Bertha Maria Júlia Lutz (August 2, 1894 – September 16, 1976) was a Brazilian feminist activist, biologist, educator, diplomat and politician. She was the daughter of Adolfo Lutz, scientist and pioneer of tropical medicine. She was also one of the most significant figures of feminism and education in Brazil in the early 20th century. </p><p>She specialized in amphibians and, in 1919, became secretary and researcher at the National Museum of Rio de Janeiro, being the second woman to be part of the public service in the country. She was later promoted to head of the Museum's Botany department, a position she held until her retirement in 1964. In August 1965, she received the title of professor emeritus at the Federal University of Rio de Janeiro (UFRJ).</p><p> In 1922, she organized the First Feminist Congress of Brazil and represented Brazilian women at the General Assembly of the League of Women Voters, held in the United States, where she was elected vice president of the Pan-American Society of Women. After returning to Brazil, she helped found the Brazilian Federation for Feminine Progress (FBPF), of which she was president until 1942 and whose main banner was the demand for women's suffrage. </p><p> In 1929, Bertha and other members of the FBPF created the União Universitária Feminina (Feminine University Union), which in 1961 was renamed the Brazilian Association of University Women. One of the primary goals of the organization was to encourage higher education by the female population. In 1937, the Union was formally invited to participate in the creation of the National Union of Students (UNE).
The Brazilian suffragette movement had a great victory on February 24, 1932, the date on which President Getúlio Vargas, through Decree No. 21 076, installed the new Electoral Code and guaranteed the right of women to vote in the country. <br /></p><p>So yes, this jumble of dates and names above is just to say that women can vote and be voted in Brazil since 1932! But in Brazil the law tends to be good, but not sufficiently enforced. As the popular saying goes "leis são como vacinas, umas pegam, outras não". But the real history is always more complicated than what we hear: here (<a href="https://butantan.gov.br/noticias/ha-mais-de-100-anos-revolta-da-vacina-foi-marcada-por-mortes-estado-de-sitio-e-fake-news">link)</a> is an example.<br /></p><p>And, it is true, in 2011, Brazil elected its first woman President, Dilma Roussef. But politics is still dominated by men, in absurd numbers. One of the new developments in which I am putting lots of hope in is the '<a href="https://midianinja.org/news/vem-ai-a-bancada-do-cocar-para-aldear-a-politica-no-brasil/" target="_blank">Bancada do Cocar</a>' (the headress caucus. More about that, especially the numbers in Brazilian politics, later on.</p><p><br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIu_a-ijaka1S4-wUoyyFM9W5aIV_i1xAipQ1eARmzDUa1ndOsswzjvf7JJ-JklZ40-HHm0vSmLklCwBmJL0W2q0a2Iv7u8lLoViQC4MSMrJ9uzN56y53jYRNliXUDYHKvijSFoJja5ite7_NnHXcoyvNWRqAJ0YnwiNOItsAOwcQByRWJpl86R5k5/s1580/BancadaCocar.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="970" data-original-width="1580" height="245" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIu_a-ijaka1S4-wUoyyFM9W5aIV_i1xAipQ1eARmzDUa1ndOsswzjvf7JJ-JklZ40-HHm0vSmLklCwBmJL0W2q0a2Iv7u8lLoViQC4MSMrJ9uzN56y53jYRNliXUDYHKvijSFoJja5ite7_NnHXcoyvNWRqAJ0YnwiNOItsAOwcQByRWJpl86R5k5/w400-h245/BancadaCocar.png" width="400" /></a></div><p></p><span class="DQEUec z1asCe K1bG5d"><svg viewbox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"></svg></span><div class="tw-menu" id="tw-smenu"><span aria-label="Text to speech" class="tw-menu-btn za3ale" data-action-target="source" data-sttse="true" data-ved="2ahUKEwiJuOT49vP6AhUdK0QIHYdiCzkQv7cBegQICBAM" id="tw-src-spkr-button" role="button" tabindex="0"></span></div><span aria-label="Clear source text" class="tw-menu-btn KTDgic" data-ved="2ahUKEwiJuOT49vP6AhUdK0QIHYdiCzkQxZgCegQICBAN" id="tw-cst" role="button" tabindex="0"><span class="tw-menu-btn-image z1asCe wuXmqc" title="Clear source text"><svg viewbox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"></svg></span></span><p></p>Valeriahttp://www.blogger.com/profile/01336528462208811726noreply@blogger.com0tag:blogger.com,1999:blog-4249190426304084757.post-44423238872875326742022-09-11T08:02:00.000-07:002022-09-11T08:02:28.345-07:00MRC@Cupertino accomplished<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfETDMpApkkBYpqIYSvdNV8AKxLxIjfuxCcZktnrJzqcr1_ADBontWoubBPWBXdc5qiEyw4RtoMIim__bHBXGxorS2Irs1-Fuoeqa9WPnaUUuSxmR-1VV9dMVRBEG-E34VzbMMWq7tpTEj0c3ZYCjzPb0TgKQ6-EZQiLT0oKvLmkT9IFROGW0pAYp0/s4032/20220909_161301.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2268" data-original-width="4032" height="225" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfETDMpApkkBYpqIYSvdNV8AKxLxIjfuxCcZktnrJzqcr1_ADBontWoubBPWBXdc5qiEyw4RtoMIim__bHBXGxorS2Irs1-Fuoeqa9WPnaUUuSxmR-1VV9dMVRBEG-E34VzbMMWq7tpTEj0c3ZYCjzPb0TgKQ6-EZQiLT0oKvLmkT9IFROGW0pAYp0/w400-h225/20220909_161301.jpg" width="400" /></a></div><br /> This week we had MRC@Cupertino. This was great! Since I had issues with tachycardia and could not go to Beaver Hollow at the end of May, some of the participants of our Mathematical Research Community (MRC) came over to work with me. We were a bit unlucky with the weather, it was far too hot to stay outside and work in the Memorial Park, as I thought we would. But the air conditioning at the Quinlan Center where we had our official meetings worked well and we've managed several sessions of recap and discussion.<br /><p></p><p> The four groups we had organized for the MRC (Dialectica and Poly, Dialectica and Lenses, Dialectica and Games, Petri Processes and implementations) had representatives and we have made some progress in these four themes. Everyone is planning to submit abstracts for the JMM in January 2023, the deadline is in two days. </p><p>As usual, I had hoped to be much further along on our discussions and wanted to be able to write something about the `Dialectica Extended Family' to complement the old papers <a href="http://www.tac.mta.ca/tac/volumes/17/7/17-07abs.html" target="_blank">Dialectica and Chu constructions: cousins?</a> and Hofstra's <a href="https://mysite.science.uottawa.ca/phofstra/dialectica.pdf" target="_blank">The dialectica monad and its cousins</a> as well as the blogposts <span style="font-size: medium;"><a href="https://topos.site/blog/2022/07/dialectica-categories-and-polynomial-functors-part-1/" target="_blank"><span style="font-weight: normal;">Dialectica categories and polynomial functors (Part 1)</span></a></span><span style="font-size: small;"><span style="font-weight: normal;"> (Nelson Niu) and </span></span><span style="font-size: medium;"><a href="https://julesh.com/2018/08/16/lenses-for-philosophers/" target="_blank">Lenses for Philosophers</a> </span>(Jules Hedges) and Sean Moss' talk in the Polynomial Workshop 2022 <span style="font-size: medium;"><a href="https://topos.site/p-func-workshop/slides/Moss.pdf" target="_blank">Dependent products of polynomials</a>.</span> But I am very slow, even more so after the cardiac issues earlier this year. </p><p><span style="font-size: small;"></span></p><p><span style="font-size: small;"><span style="font-weight: normal;"><span style="font-size: medium;">Also collaborative research has perks (you can get much more done), but also drawbacks: you must learn from the differences. So it doesn't go as you want it, it goes as all of you want it, to go. Collaborators have ideas and agendas of their own, which is wonderful. And it is also true that research in general doesn't go the way you expect it: if it always did, it wouldn't be research, but simply development. I am very aware that I need to let go of some of my old fashioned wishes for the Dialectica categories.</span><br /></span></span></p><p> </p><p><br /></p>Valeriahttp://www.blogger.com/profile/01336528462208811726noreply@blogger.com0tag:blogger.com,1999:blog-4249190426304084757.post-88428474313002283122022-07-14T11:57:00.000-07:002022-07-14T11:57:05.239-07:00Healthy or Sick?<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOLioOli3Oet-Mh3OY2Uov4vm7ysDzSj9d8wZEoRodrVu5m5tbypibA03wY-_jttjp6s9ZmgoF3c3nh86Si-l_OpMtUndotk8FTNN6UhM_BxSNkSuezgIyiWb3b5ohQgw3lIUuJ_DQ-xbA55Ua6Ik2FXg99eXKXexTrYdbrIFnkhJG2apZP-v3uwTJ/s1398/inspirationalquote%3F.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="740" data-original-width="1398" height="211" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOLioOli3Oet-Mh3OY2Uov4vm7ysDzSj9d8wZEoRodrVu5m5tbypibA03wY-_jttjp6s9ZmgoF3c3nh86Si-l_OpMtUndotk8FTNN6UhM_BxSNkSuezgIyiWb3b5ohQgw3lIUuJ_DQ-xbA55Ua6Ik2FXg99eXKXexTrYdbrIFnkhJG2apZP-v3uwTJ/w400-h211/inspirationalquote%3F.png" width="400" /></a></div><br /><p></p><p> I wanted to recap the papers I have written recently.

Then I got ill and had to be taken to the emergency room in the Stanford Hospital. Twice. <p></p><p>The first time I went simply to see my general doctor because I was feeling a bit weak, but the doctors didn't like my pulse rate at all and send me to the ER immediately. I thought it was a big joke, as I was feeling fine, I didn't even realize that my heart was racing. They did something that I thought was a small miracle of science: a cardioversion. This is when they inject a drug that stops your heart for a second and that reboots it. So I thought they had solved the problem and then I wanted to go home and forget all about it.</p><p>However, four days later, the same thing happened again. This time I was fully aware of the heart racing and I panicked quite a bit. I ended up having another cardioversion, but I wasn't marvelling at their technology anymore. I was just worrying that this might be it. That I was going to die of an overzealous heart. </p><p>I stayed in the hospital one night, under the counselling of a young ER doctor who said, `if you were my mom, I wouldn't let you out of here'. That was pretty convincing. In the hospital I started medication and, the next day, met my cardiologist. I am now trying to take small steps in the direction of accepting that instead of being super healthy and able to do anything I want, I am now very fragile, as this whole thing might start again, from nowhere. <br /></p><p>This whole drama meant that I was not able to participate of our MRC fully. I tried at the distance, but it doesn't work very well. More than the two years (pandemic issues) in the making and the last month of intense preparation have at least meant that the group was able to do quite a bit. I'm extremely proud of the Team Dialectica, pictured below.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_Y6Qr55Eip31sGNeIrmqsaK0L2yQgF3KoX5QEv9SxWEZL6syQeMtURvV9J_wOtflnez1_U-R_va6SSFyeVecLzDFbQq9jUey_rRFUbumaqxjJ_1h-aauXJ4c-PQe-5iZYD6ib_CD9b4MgcyNiZLWHhI6IroQIXDQn5g7a-l2om_sCsVMvvfM1e_F4/s4032/MRCgroupphoto.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3024" data-original-width="4032" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_Y6Qr55Eip31sGNeIrmqsaK0L2yQgF3KoX5QEv9SxWEZL6syQeMtURvV9J_wOtflnez1_U-R_va6SSFyeVecLzDFbQq9jUey_rRFUbumaqxjJ_1h-aauXJ4c-PQe-5iZYD6ib_CD9b4MgcyNiZLWHhI6IroQIXDQn5g7a-l2om_sCsVMvvfM1e_F4/w400-h300/MRCgroupphoto.jpg" width="400" /></a></div>Our group was divided into 4 subgroups: Dialectica and Games (Jeremie), Dialectica and Poly (Nelson), Dialectica and Lenses (Bruno and Matteo), and Dialectica Petri Net implementations (Eric). The names in parentheses are the leads of the subgroups. The issues are overlapping, of course. And the competencies and backgrounds of the participants are very different. But I'm told the group had a good time, despite the fact that one of our own got covid there or getting there. He's fine now though!<br /><p></p><p>The presencial phase of the MRC is done, but now comes the second phase, working out the ideas discussed during the brainstorm in Beaver Hollow. I am not very sure how this phase is supposed to go, but I do hope we'll be able to get papers from all the subgroups!<br /><br /></p>Valeriahttp://www.blogger.com/profile/01336528462208811726noreply@blogger.com0tag:blogger.com,1999:blog-4249190426304084757.post-21671638276906336032022-04-23T15:18:00.000-07:002022-04-23T15:18:48.722-07:00Natural Language and Computer Science (NLCS): what's that?<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAT39Z0vwwBKP7evcreHc_MSThkwFirgnSRL6MB_mzORrgYH0LNuO9_PaXD0nUZpiLLCRntOXpaKOcXhIgU1oZGpLnEP1361T5rYuAxWLasEURP0GlhwxUwfPqF4X4N1X7mxpAW0YUa51Fu8FDOqZcMmbmCC4aVlA7K9tMCtUOy61Q2i0bHLEh46MK/s768/lmoss.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="768" data-original-width="768" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAT39Z0vwwBKP7evcreHc_MSThkwFirgnSRL6MB_mzORrgYH0LNuO9_PaXD0nUZpiLLCRntOXpaKOcXhIgU1oZGpLnEP1361T5rYuAxWLasEURP0GlhwxUwfPqF4X4N1X7mxpAW0YUa51Fu8FDOqZcMmbmCC4aVlA7K9tMCtUOy61Q2i0bHLEh46MK/s320/lmoss.jpg" width="320" /></a></div><br /> Larry Moss (pictured above in the official department photo) and I have worked on our small workshop NLCS (Natural Language and Computer Science) for several years now. The main goal of the workshop was to introduce our friends in theoretical computer science to the extremely nice problems that NL semantics and computational linguistics throws at us, as logicians. And conversely.<br /><p></p><p>The first edition of the workshop happened in <a href="https://iulg.sitehost.iu.edu/nlcs2013.html">New Orleans in 2013</a> and it was a lot of fun. As we said, when introducing the workshop, associated to LiCS 2013:</p><p style="margin-left: 40px; text-align: left;">Formal tools coming from logic and category
theory are important in both natural language semantics and in
computational semantics.
Moreover, work on these tools borrows heavily from all areas of
theoretical computer science.
In the other direction, applications having to do with natural
language have inspired developments
on the formal side. </p><p>We were then and still are interested in work covering both directions: work in NL that is an application of work in CS and work in CS that uses the tools of NL. For that first edition of NLCS we had as Invited Speakers <a href="http://www.ling.gu.se/~cooper/">Robin Cooper</a>, <a href="http://www.cs.man.ac.uk/~ipratt/">Ian Pratt-Hartmann</a>, and <a href="http://researcher.watson.ibm.com/researcher/view.php?person=us-wlodz">Wlodek Zadrozny</a>, then recently arrived at UNC, Charlotte, from IBM. Our program committee was very small, us, <a href="https://en.wikipedia.org/wiki/Annie_Zaenen">Annie Zaenen</a> and <a href="https://www.linkedin.com/in/billmaccartney/">Bill MacCartney. </a></p><p> Maybe the acronym wasn't a very clever idea, as baseball will always be much more popular and the <b><a href="https://en.wikipedia.org/wiki/2013_National_League_Championship_Series">National League Championship Series</a> </b>makes us all but unfindable in the internet.<br /><b></b></p><p>After that we had <span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><strong><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><a href="https://www.easychair.org/smart-program/VSL2014/NLCS-program.html">NLCS'14</a>, </span></strong></span></span></span></span><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><strong><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><a href="https://easychair.org/smart-program/NLCS%2715/index.html">NLCS'15</a>, </span></strong></span></span></span></span><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><strong><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><a href="https://iulg.sitehost.iu.edu/nlcs16.html">NLCS'16</a>, </span></strong></span></span></span></span><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><strong><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><a href="https://iulg.sitehost.iu.edu/nlcs2018.html">NLCS'18</a> and </span></strong></span></span></span></span><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><strong><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"><a href="https://iulg.sitehost.iu.edu/nlcs.html">NLCS'19</a>.</span></strong><span style="color: #330000; font-family: Arial, Helvetica, sans-serif;"> So six workshops so far.

I tried to describe the research clusters above. <p></p><p>Yes, the last axis, the lexical resources stuff has been suffering a bit lately, as has the Natural Language inference. This is because the Dialectica Spaces are taking all the 'oxygen' available. Because good things need to happen before our MRC programme gets off the ground soon. Unfortunately the Dialectica spaces are not going very far, either. </p><p>Some things have been happening, e.g. the two papers with Davide and Matteo are very cool indeed. and I'm hoping for lots more on the subject.<br /></p><p>Elena, Wilmer and I managed to submit our "<a href="https://arxiv.org/abs/2105.12801">Dialectica Petri Nets</a>", which is great. </p><p>Katerina, Livy and I managed to describe some simple, but interesting application of basic transformers technology, i.e. spaCy, to historic text. Where there's text, there are applications of spaCy, I'm sure.<br /></p><p>But by and large I am losing the war. I need to finish my ill-fated research proposal, I need to resubmit the three papers that were rejected last year, I have to prepare two Invited talks, I have several rounds of reviews that I need to deal with yesterday, I am only half way through with the posts about the DLMPST, the <a href="https://dlmps.org/"><i>Division of Logic, Methodology and Philosophy of Science and Technology</i></a>.</p><p>Also, for this blog, I need to do a similar job to the one I did with <a href="http://logic-forall.blogspot.com/2022/01/twelve-days-of-christmas.html">Twelve Days of Christmas</a>: I need to see which papers have been written from my list of talks at <a href="http://logic-forall.blogspot.com/2022/01/talking-talk.html">Talking the Talk</a>.

As are hummingbirds. And the blossom in the garden is almost all gone already, while I despair of getting my work done. Yes, I know I need to say no, I need to decline invitations to speak, to review, to teach, to record and/or to judge stuff. And I need to get back to my yoga, to some aerobic exercises, to cooking some decent food--instead of pretending that not eating will make me less fat. It won't, it only makes me cranky and ugglier.<p></p><p>But while I do have all these wishful thoughts, there's a very finite number of truly awaken hours in the week and an awful lot of stuff that needs to happen in these hours. I could do without friends turning out to not be good friends after all. I guess it's the curse of getting excited about people and projects: it comes with big disappointments too.</p><p>Anyways here are two videos, which have nothing to do with disappointing friends.

I was even unsure whether the country was called Romania, Roumania or Rumania. (I have now learned that since 1975 it is Romania).<br /></p><p>I had only known about Dracula and Transylvania and <a href="https://en.wikipedia.org/wiki/Trial_and_execution_of_Nicolae_and_Elena_Ceau%C8%99escu">Nicolae and Elena Ceaușescu's execution</a>, as dreadful grainy pictures in old newspapers. So I was in a bit of a bind to tell a story about this congress, as I have been writing about <a href="http://ogic-forall.blogspot.com/2022/01/1st-international-congress-stanford-1960.html">others</a>. </p><p>Of course the hard information about the Congress is <a href="http://dlmps.org/pages/past-congresses/bulletin-1.php#cng71"> available</a>. Most of the program committee consists of very well known logicians: P. Suppes (Chairman), A. Mostowski,
A.A.
Markov, M. Rabin, G. Kreisel, W. Stegmüller, K. J. J. Hintikka,
A.
Grünbaum, M. O. Beckner, A. N. Leontiev, P. Lazarsfeld, S. Marcus, and
M.
Hesse as Section Chairmen. This way I 'discovered' the work of <a href="http://www.collodel.org/hesse/#sthash.qkEPJJhc.HvxrVvYW.dpbs">Mary Hasse</a> and you should too.<br /></p><p>I also read about the Romanian Organizing Committee: A. Joja, G. Moisil, C. Popovici (General Secretary) and wondered about how close this congress was of the taking of power by Ceaușescu. I read most about Moisil, because I like algebraic logic. But this is not a sensible blog post material here. </p><p>So I ended up looking up the President of the Executive Committee of the Congress, <a href="https://en.wikipedia.org/wiki/Stephan_K%C3%B6rner">Stephan Körner</a>, The University of Bristol BS8 IRJ, England. I learned that he was the father of <a href="https://en.wikipedia.org/wiki/Stephan_K%C3%B6rner">Tom Korner</a>, who was one of my professors in the Cambridge Part III course. Tom was an extremely nice professor, not only to me, but to generations of Part III students. His <a href="https://www.dpmms.cam.ac.uk/~twk/">website</a> gives a glimpse of his kind of self-deprecating humour, which I always enjoyed, once I was able to understand it.</p><p>Tom has some <a href="https://www.dpmms.cam.ac.uk/~twk/PartIII.pdf">advice</a> for people taking Part III in his website. This brought back loads of memories of my year doing Part III in Cambridge: it definitely was the hardest course I've done in my life, by a very long stretch. So it's kind of comforting that <a href="http://www.arvindguptatoys.com/arvindgupta/mathsapology-hardy.pdf">much more accomplished people</a> than me also say so. <br /></p><p>Reading his advice I was reminded of a story from when I first started in Cambridge. I could read English well and I could take exams fairly well (I was accepted in most of the Mathematics departments I applied to do my Phd), but I had been thinking of going to France, where I knew a professor doing categorical model theory. Hence my spoken English was terrible and my understanding of spoken English was even worse. For a few weeks in the beginning of Part III lectures, the abbreviation (TFAE = the following are equivalent) was written in the huge blackboards<br /> of the Mill Lane Lecture rooms over and over. Little me assumed that the letters where the initials of some very famous mathematicians, so I kept thinking to myself, these guys, who are they? They're everywhere, even more than Gauss? How come I never heard of them? Eventually the penny dropped, but I think this shows how hard that first year was. <br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhbw2biFXtn263Eck-VF-PcPQuSPXdcT1Bx2wSkHvzdYqdU8_A4RJeQZpnKDiMsI4E68cTT95xeU2mWchPlwJH4iTiYx6L3NRsrZO_SJZVzPLiZAk5HyZvvs7oJQoZC_e_mK3GSJZVV3RjlrEpAlLzo4U9mmyf09l1NSq9_YqomaOfbYL4kzRv_H26N=s600" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="487" height="320" src="https://blogger.googleusercontent.com/img/a/AVvXsEhbw2biFXtn263Eck-VF-PcPQuSPXdcT1Bx2wSkHvzdYqdU8_A4RJeQZpnKDiMsI4E68cTT95xeU2mWchPlwJH4iTiYx6L3NRsrZO_SJZVzPLiZAk5HyZvvs7oJQoZC_e_mK3GSJZVV3RjlrEpAlLzo4U9mmyf09l1NSq9_YqomaOfbYL4kzRv_H26N=s320" width="260" /></a></div><p></p>Valeriahttp://www.blogger.com/profile/01336528462208811726noreply@blogger.com0tag:blogger.com,1999:blog-4249190426304084757.post-11985960058178078632022-01-06T08:20:00.000-08:002022-01-06T08:20:25.197-08:009th International Congress, Uppsala 1991<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEia6EmTyYhegT-hq-HQFLj5BTByTQ8i1MFFagbLq0a-BRNoBWw9ggclVNkGzusBP-2JAPQKxGZVxJGhMEIOeZxoHMqtP-UIKbMLJX3kvM0iilNrMd1C0x_4ZEf8Aw80zVFoSTfi3QKK_92F3lHKsMtbqYIcGdHgYpAxcTJA5Ia0dCKO_UVPqDkpPkxg=s2048" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2048" data-original-width="1536" height="400" src="https://blogger.googleusercontent.com/img/a/AVvXsEia6EmTyYhegT-hq-HQFLj5BTByTQ8i1MFFagbLq0a-BRNoBWw9ggclVNkGzusBP-2JAPQKxGZVxJGhMEIOeZxoHMqtP-UIKbMLJX3kvM0iilNrMd1C0x_4ZEf8Aw80zVFoSTfi3QKK_92F3lHKsMtbqYIcGdHgYpAxcTJA5Ia0dCKO_UVPqDkpPkxg=w300-h400" width="300" /></a></div>This photo is kind of recent (Tuebingen, 2019) and I am happy that I've decided to assume that I'm really a groupie and asked Per for a joint photo! Even happier that he didn't decline.

I had just finished my PhD and submitted a short abstract about the thesis, actually about a development of the thesis, the work with Martin Hyland on <a href="https://reader.elsevier.com/reader/sd/pii/0168007293901465?token=BA7A6265A871593BDF92F13196BBB5ACE529BEB569844F66339792BDA78E69A8BCE301FD459B1180A020BFC8AA9BB3A3&originRegion=us-east-1&originCreation=20220106153621">Full Intuitionistic Linear Logic (FILL).</a> I presented my abstract thoroughly convinced that both Linear Logic and Category Theory were the best things in the world, since sliced bread, and that everyone in the audience would know it and agree with it. When I finished, a Swedish (I assumed) professor asked me: So this is all very well, I can see that the mathematics is neat, but if this is logic, how do you explain what your "par" is to a man in the street?</p><p>Well, I didn't know to reply to him then. And I didn't know this was Professor Martin-Loef. And in some ways, I still do not know the best answer for his hard question. (I had thought he would like FILL, given FILL's commitment to intuitionistic linearity).</p><p> Later on, when he visited Brazil, we took a long walk, chatting about logic, the universe and everything in Jardim Botanico. Prof Martin-Loef really appreciated our Botanical Gardens and would go there everyday before doing any work at the University. I really wish that I had had more time to ask more questions, but I had young kids to look after and I have never been very good at grabbing the right opportunities. </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiExbO3h5BSlFPUcvqITzgYCeF7CLQHrcylU3a5vJ6VN40VhqyDYjxVFQ68HJgzhXN2ofcPOW9TNTitlJRHPFYsH5yfXldfnUC5L4H7fI72KHsYtztUY5PWsTY2aG8i1FDnHcMeBiNvzmKyi8v9i8HybW-ylqTOtM87z7bOInzNbEMLRD4ZwqAbqC8O=s994" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="745" data-original-width="994" height="300" src="https://blogger.googleusercontent.com/img/a/AVvXsEiExbO3h5BSlFPUcvqITzgYCeF7CLQHrcylU3a5vJ6VN40VhqyDYjxVFQ68HJgzhXN2ofcPOW9TNTitlJRHPFYsH5yfXldfnUC5L4H7fI72KHsYtztUY5PWsTY2aG8i1FDnHcMeBiNvzmKyi8v9i8HybW-ylqTOtM87z7bOInzNbEMLRD4ZwqAbqC8O=w400-h300" width="400" /></a></div><br /> <p></p><p>I am hoping to use some of 2022 to think and write about the answers I have, so far.
