Using WordNet to Measure Semantic Orientations of Adjectives
Proceedings of the Fourth International Conference on Language Resources and Evaluation (LREC 2004)
Abstract
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.
