Abstract—Semantic composition in distributional semantic models (DSMs) offers a powerful tool to represent word meaning in context. In this paper, we investigate methods to utilize compositional DSMs to improve word sense discrimination and word sense disambiguation. In this work, we rely on a previously proposed multiplicative model of composition. We explore methods to extend this model to exploit richer contexts.

This chapter explores the different sources of linguistic knowledge that can be employed by WSD systems. These are more abstract than the features used by WSD algorithms, which are encoded at the algorithmic level and normally extracted from a lexical resource or corpora. The chapter begins by listing a comprehensive set of knowledge sources with examples of their application and then explains whether this linguistic knowledge may be found in corpora, lexical knowledge bases or machine readable dictionaries.

The author builds on recent work that indicates that distributional models can in fact distinguish to some extent between semantic relations, and argues that (the right kind of) distributional similarity indicates property overlap, and proposes a probabilistic account of semantic knowledge that can learn from such data.
