A Possibilistic Approach for Automatic Word Sense Disambiguation

This paper presents and experiments a new approach for automatic word sense disambiguation (WSD) applied for French texts. First, we are inspired from possibility theory by taking advantage of a double relevance measure (possibility and necessity) between words and their contexts. Second, we propose, analyze and compare two different training methods: judgment and dictionary based training. Third, we summarize and discuss the overall performance of the various performed tests in a global analysis way. In order to assess and compare our approach with similar WSD systems we performed experiments on the standard ROMANSEVAL test collection.
