Thomas Graf is giving an invited talk at UConn! (April 21)

Thomas Graf is giving an invited talk in the UConn Logic Colloquium series this Friday, April 21! The title of his presentation is Fragments of First-Order Logic for Linguistic Structures. The meeting will be held at UConn, Storrs, CT.

Logic has always played a central role in the study of natural language meaning. But logic can also be used to describe the structure of words and sentences. Recent research has revealed that these structures are so simple that they can be modeled with very weak fragments of first-order logic. Unfortunately, many of these fragments are still not particularly well-understood on a formal level, which has become a serious impediment to ongoing research. This talk is thus equally about the known and the unknown: I will survey the empirically relevant fragments of first-order logic and explain how they allow for completely new generalizations about linguistic structures at the word and sentence level. But I will also highlight the limits of our current understanding and which mathematical challenges need to be overcome if the logical approach to natural language is to realize its full potential. Hopefully, an alliance of linguists, logicians, and computer scientists will be able to solve these problems in the near future.
