A Similarity Measure for Unsupervised Semantic Disambiguation
Roberto Basili, Marco Cammisa, Fabio Massimo Zanzotto · 2004
This paper presents an unsupervised method for the resolution of lexical ambiguity of nouns.The method relies on the topological structure of the noun taxonomy of WordNet where a notion of semantic distance is defined.An unsupervised semantic tagger, based on the above measure, is evaluated over an hand-annotated portion of the British National Corpus and compared with a supervised approach based on the Maximum Entropy Model.
