Google & WordNet based Word Sense Disambiguation

This paper presents an unsupervised methodology for automatic disambiguation of noun terms found in domain specific unrestricted corpora. This method extends approaches of Fragos (Fragos et al., 2003) and others that use the WordNet (Miller, 1998) database in order to resolve semantic ambiguity. The method is evaluated by disambiguating the noun collection of SemCor 2.0. Parameter adjustment was performed using a supervised technique that significantly increased the accuracy.
