Using Domain Information for Word Sense Disambiguation

Abstract

The major goal in ITC-irst's participation at SENSEVAL-2 was to test the role of domain information in word sense disambiguation. The underlying working hypothesis is that domain labels, such as MEDICINE, ARCHITECTURE and SPORT provide a natural way to establish semantic relations among word senses, which can be profitably used during the disambiguation process. For each task in which we participated (i.e. English all words, English 'lexical sample' and Italian 'lexical sample') a different mix of knowledge based and statistical techniques were implemented. 1
