Linking and Harmonizing Different Lexical Resources: a Comparison of Verbal Entries in ItalWordNet and PAROLE-SIMPLE-CLIPS

During the last years, in the framework of Computational Linguistics, many lexical resources have been developed which aim at coding complex lexical semantic information according to different linguistic models (WordNet, Frame Semantics, Generative Lexicon, etc.). However, these resources are often not easily accessible nor available in their entirety. Yet, from the point of view of the continuous growth of the technology (Semantic Web), their visibility, availability, integration and harmonization are becoming of utmost importance. ItalWordNet and PAROLE/SIMPLE/CLIPS are two resources which, tackling lexical semantics from different perspectives and being at least partially complementary could profit from linking each other. In this paper we address the issue of linking these resources focusing on the most problematic part of the lexicon: the second order entities. In particular, after a brief description of the two resources, their different approaches to the verb semantics are described; an accurate comparison of a set of verbal entries is carried out, with a view to evaluating the possibilities and the advantages of a semiautomatic link; finally, the results and the future work are illustrated.
