Chapter 10: Domain-Specific WSD

Paul Buitelaar, Bernardo Magnini, Carlo Strapparava, Piek Vossen

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 domain-specific tuning of semantic resources in a top-down or bottom-up fashion.
