| Abstract | In this article, we present an experiment of linguistic parameter tuning in therepresentation of the semantic space of polysemous words. We evaluatequantitatively the influence of some basic linguistic knowledge (lemmas,multi-word expressions, grammatical tags and syntactic relations) on theperformances of a similarity-based Word-Sense disambiguation method. Thequestion we try to answer, by this experiment, is which kinds of linguisticknowledge are most useful for the semantic disambiguation of polysemous words,in a multilingual framework. The experiment is about 20 French polysemous words(16 nouns and 4 verbs) and we make use of the French-English part of thesentence-aligned EuroParl Corpus for training and testing. Our results show astrong correlation between the system accuracy and the degree of precision ofthe linguistic features used, particularly the syntactic dependency relations.Furthermore, the lemma-based approach absolutely outperforms the wordform-based approach. The best accuracy achieved by our system amounts to 90%. |
