Domain-Specific WSD

Abstract

This chapter describes a number of approaches to word sense disambiguation, which take the wider “semantic space” of ambiguous words into account.Semantic space may be instantiated by a specific domain, task, or application. Approaches discussed include the use of subject codes as specified in dictionaries or manually added to WordNet and similar semantic resources, the extraction of topic signatures through a combined use of a semantic resource and domain-specific corpora, and domainspecific tuning of semantic resources in a top-down or bottom-up fashion.
