Syntax-Semantics Integration in HPSG

Abstract

In recent years, there has been an increasing interest in the interface between morphosyntax and semantics. One of the main reasons for that is that generalizations over word classes have been proven to help linguistic theories and large-scale grammar implementations overcome the natural limitations of syntax.

In lexicalist theories like Head-Driven Phrase Structure Grammar (HPSG), as well as in the large-scale grammar implementations based on it, the interest in the interaction between morphosyntax and semantics has led to the development of Computational Semantics (CS) formalisms, like the Hierarchical Lexicon models and MRS (Minimal Recursion Semantics).

The aim of this course is to present and explore approaches on empirical and computational issues related to the morphosyntax-semantics interface in HPSG. The course will also focus on CS formalisms in real life, with emphasis on CS components of large-scale, large-coverage HPSG grammars and CS for hybrid (deep and shallow) natural language processing.
