The Lexico-semantic Annotation of an Italian Treebank

Corpora annotated at semantic level play a crucial role both in research and in applicative contexts in which systems of natural language processing are studied and developed. In this paper we present the lexico-semantic annotation of an Italian treebank, a first attempt to recover the lack of such resource for Italian. We will describe the annotation realized, focusing on the methodology followed, the results achieved, and possible further work and applications.
