How are meanings of utterances related to the world and our perception of it? What is meaning, and how is it created? How do word meanings contribute to utterance meaning? We are working towards a formal semantics that aims to provide answers to these and related questions, starting from situated interaction between agents. The meanings of many expressions can be modeled as classifiers of real-world information. Expressions can be single words, or phrases and sentences whose meanings are composed from the meanings of their constituents. By interacting, agents coordinate on meanings by training classifiers. To make formally explicit the notions of coordination, compositionality and classification, and to relate these notions to each other, we use TTR (a type theory with records).

Staffan Larsson (b. 1969) was educated at University of Gothenburg (1992-1996) and gained a PhD in Linguistics there (1997-2002). Since 2013, he is Professor of Computational Linguistics at the Department of Philosophy, Linguistics and Theory of Science at the University of Gothenburg. He is also a member of CLASP (Centre for Research on Linguistic Theory and Studies in Probability) and co-founder and Chief Science Officer of Talkamatic AB. His areas of interest include dialogue, dialogue systems, language and perception, pragmatics, formal semantics, semantic coordination, and philosophy of language.
