Abstract: Automatic word sense disambiguation (WSD) often draws on a variety of contextual cues, and decides on the most suitable sense by means of some lexical resources or statistical classifiers. While the importance of using multiple types of lexical information is recognised in most systems, not much has been reported on their individual and combined effectiveness in relation to the intrinsic nature of individual words. We attempt to address this cognitive aspect of WSD by examining the psychological evidence regarding the internal lexicon and its compatibility with the information available from computational lexicons. In this study, we compare the responses from a word association task with the lexical associations available from WordNet, to explore the effect of sense abstractness on semantic activation, and thus the implications on the lexical sensitivity of WSD. Preliminary results suggest that concrete senses and syntagmatic associations are more readily activated than abstract sens es and paradigmatic associations. The results are expected to inform the construction of lexico-semantic resources and WSD strategies. (More)
