Friday this week (March 11), at 16:00, in room LB01, Lloyd Building
(TCD), Professor András Kornai (Budapest Institute of Technology)
speaks on:
The Unity of Semantic Theories
In this talk we discuss two classes of semantic theories, algebraic
conceptual representation (ACR) and continuous vector space (CVS)
models. Together with Montague grammar (MG) and its lineal descendants
(Discourse Representation Theory, Dynamic Predicate Logic, etc.) we
now have three broad families of semantic theories competing in the
same space, but relying on seemingly very disparate formalisms: ACR on
graphs, hypergraphs, and Eilenberg machines (a generalization of
finite automata/transducers); CVS on finite (and more recently,
infinite) dimensional vector spaces over the reals; and MG-style
theories on logic formulas. In addition, there are less formal, but
widely influential linguistic/cognitive theories of semantics, such as
prototype semantics and force dynamics, that seem to capture important
insights. In this talk we will try to relate these to one another.
