ItalWordNet (IWN) is a lexical-semantic database developed in the framework of two different research projects: EuroWordNet (EWN) and Sistema Integrato per il Trattamento Automatico del Linguaggio (SI-TAL).
IWN is structured in the same way as the Princeton WordNet, namely around the notion of synset. Following the model designed in EWN, IWN encodes a rich set of semantic relations. In addition to the internal language relations, equivalence relations were also encoded between Italian synsets and the closest concepts in an Inter-Lingual Index (ILI), a separate language-independent module containing all WN1.5 synsets but not the relations among them.
IWN now contains information about Italian Nouns, Verbs, Adjectives and Adverbs.
This SQL version of IWN v2.0 contains a corrected and revised version of the original IWN:
49350 Synsets (of which: 3459 proper nouns, 32073 nominal, 8903 verbal, 4374 adjectival, 541 adverbial)
48416 Lemmas (of which: 3918 proper nouns, 29527 nouns, 8015 verbs, 5808 adjectives, 1090 adverbs)
68478 Senses
