Using WordNet to Measure Semantic Orientations of Adjectives

Current WordNet-based measures of distance or similarity focus almost exclusively on WordNet's taxonomic relations.This effectively restricts their applicability to the syntactic categories of noun and verb.We investigate a graph-theoretic model of WordNet's most important relation-synonymy-and propose measures that determine the semantic orientation of adjectives for three factors of subjective meaning.Evaluation against human judgments shows the effectiveness of the resulting measures.
