9-13th of December 2019: Together with Samson Abramsky and Alessandra Palmigiano we organised a Lorentz Centre workshop on Logic and Structures in Computer Science and Beyond, see here for the programme and description. We had a very nice combination of long and short impromptu talks, as well as very fruitful discussion and breakout sessions. I learnt quite a lot about contextually and Fock spaces.

On 10th of December, I gave the Lunchtime lecture for the Lorentz Centre’s Faculty of Science “This weeks discovery”, with title “Understanding natural language: logic or statistics, which one is more important?”.

16th of September 2019: I gave a talk in the Theoretical Neurobiology research group of the centre for Human NeuroImaging. The title of the talk was “Convergence in Dialogue via Incremental Vector Representations” and the material was based on our SemDial 2018 paper with Matt Purver, Ruth Kempson, and Julian Hough. Based on some recent joint work, I argued that a principle similar to the principle of free energy used by Prof. Karl Friston in the brain, can be applied to linguistic data exchanged by humans to achieve a degree of synchrony in dialogue, by measuring the decreasing rate of the distances between utterances vectors of the dialogue.

5th of September 2019: I gave an invited talk titled “String diagrammatic reasoning in natural language processing” in the joint STRING-SYCO in Birmingham. It was a very nice event, thanks Dan for inviting me.

I had 4 students: Dan Shiebler, Aexis Toumi, Adriana Correia, and Lachlan McPheat. Together, and with the help of the TA of the course, Gijs Wijnholds, we worked on vector space models of language for dialogue and discourse, and discovered the role of coalgebras and Fock Space comonads on vector spaces. For a blog post on the n-categories cafe, see here. We are planning to write up the results soon!

17th of June 2019: I was awarded a Royal Academy of Engineering Industrial Scheme Fellowship for the second time! This will start in September and end for a year and I will work on “Cross Domain Unified Representations for Content Similarity” with the BBC R&D’s Chris Newell and Andrew McParland. We are going to find a representation for different types of information encoded in a programme (TV, Radio, News) so that they correlate with the viewers’ behaviours.
