Old Stories

This amazing picture taken, I presume, at Pico da Neblina, Brazil reminds me very much of Isabel Allende's young adult novel City of the Beasts.  I liked it very much when I first read it. Rechecking it in Wikipedia just now, I guess I  am really not very sophisticated in my love of books.

Anyways, the point of this post is to remember old stories of a very different kind. This deck contains the slides of my first talk at Nuance, in October 2012.

To show, once again, that I really need to be better at organizing my work, I talked about this deck  in this blog post, in this one and in this post.

More BACAT slides

I'm pretty useless at keeping track of what I have and have not done and when. So here are the slides from when I talked in BACAT in Sept 2017 about Temporal Logic, "Doing Time, Categorically".

This was a paper with my collaborator Harley Eades III for a special issue of the IfColog Journal in honour of Grigori Mints. I feel that I need to improve on this paper and I also need to carry on with the project of constructive modal logics, but not now, as other requests on my time are taking precedence.

Santa Clara in February

Yesterday I talked at BACAT (Bay Area Categories And Types) and it was a lot of fun. When I searched for my old slides  I thought that I hadn't spoken at BACAT for a long while, since 2014. But this was only because I cannot find anything on my computer. In reality, I had talked in Sept 2017 about temporal logic. Still, this was a long time ago and the old building where Computer Science had classes has been demolished.

But the campus is now looking lovely and I wish I had taken pictures.

The slides for the talk are here.  I liked my title "Going Without: a modality and its role" because the ambiguity works on my favour, for once. The slides are a bit rough, as BACAT talks are fun because you can afford to be tongue-in-cheek and outrageous, if you so wish.

Organizing Talks

Organizing talks is an art, and as such, it can be lots of hard work, as well as plenty of fun. But since it happens bit by bit you can only see how hard you've worked with hindsight. I've organized six years of talks at Nuance Sunnyvale Lab, 202 talks, in total, I believe.

Sure, lots of other people helped too, but I think most of the work was actually mine. There were times that I thought it was a waste of time and thought I'd stop doing it. But I really enjoy listening to engaging talks, and I do have plenty of very engaging friends, so I usually went back to organizing it. Most of the talks were academic and about stuff already published. I do not have the abstracts or slides for most of the talks, so I hope none of the presenters will be offended that in the attachment there is simply a spreadsheet with their name and the titles of the talks.

Google Plus is going away

So Google decided to shut down Google+. A shame as the product always gave me the mistaken impression that I had some sort of internet presence. You see, I do have (and follow) a few famous friends and some of their fame 'splashes' over me. Anyways the reason for this post is to try to remind me to save all the bits of writing and links I have in the service. Because the last two times Google terminated a product I was to busy to save my data and I regret it (bitterly) to this day. I lost an immense number of photos...

Amsterdam in January

I'm flying back to California tomorrow, after a week in Amsterdam. The conference SYSMICS  2019 ( was great. Plenty of interesting talks on all kinds of stuff that I like: dualities, Heyting algebras, lax logic,  topologies, you name it. Several conversations on Dialectica categories and what I (still) want to do with them

Very grateful to Yde Venema and Nick Bezhanishvili for inviting me!

The conversations outside the official talks were great too. There was an Evening Lecture on AI, given by Frank van Harmelen that was great fun, once I managed to find my way there, without being run over by an angry cyclist. Quite amazing how even with an iphone and various kinds of maps, I can still get lost and walk in the opposite direction from the one I am trying to go.

But the best of non-work stuff was hanging out with Jan van Eijck and Heleen Verleur for her play and music concert and chats. Thanks Jan!

Who uses OpenWordNet-PT?

I have been guilty of not knowing exactly who's using the OpenWordNet-PT (our Portuguese wordnet) and for what, so I decided to write this blog post, which intends to be (some day) a bibliography of work using/citing OWN-PT, when I eventually get it done.

I am using Google Scholar for this laundry list, so it comes in order of more citations, not the year of publication. And I removed our own work, as I think it needs to be in a separate laundry list. Of course, what is our own work is a bit debatable. It is not simply about who are the authors, but whether the work is about lexicography/lexical resources or not, I think.

Of course, I have not read all the papers below. Yet. So there might be some that are repeated (I tried to avoid it, though) and some that only cite the OWN-PT to say `one shouldn't touch with a barge pole'. But still, I think I should read them all.

Google tells me that we have 75 citations now (Dec 2018). As usual, many are from our own work and many are counted twice, and 45 papers to read seems a task hard enough. Anyways, many of the papers below have Hugo G. Oliveira as an author, many thanks, Hugo!
