Description

Statistical models of semantics are successfully applied to areas such as word sense disambiguation, acquisition of lexical semantic relations, or assignment of predicate-argument structure. This talk will take a closer look at linguistic concepts that have been thoroughly investigated in formal theoretical semantics: Genericity and Presupposition.

In recent work Reiter & Frank (2010) and Tremper & Frank (2012) offer a treatment of these two phenomena within the framework of corpus-based statistical semantics. The proposed models take different perspectives on the interplay between formal-theoretical andcorpus-based statistical semantic analysis, and investigate whether
(1) statistical semantics can yield novel insights for formal semantics, and whether
(2) formal semantics can deliver linguistic insights to guide statistical models of semantics.

In fact, by investigating the distributional features that permit their classification, we can gain insights into linguistic factors that determine the interpretation of NPs as generics.

By analyzing the discriminative linguistic properties of presupposition in contrast to other inferential relations, such as entailment, troponoymy or antonymy we devise a discriminative classifier for semantic relations that yields high classification performance.
