The Laboratory for Computational Linguistics of the University of Pisa,
Dept. of Linguistics, is pleased to announce LexIt, a corpus-based
computational resource to investigate the argument structure of Italian
predicates.

LexIt data can be freely explored at: http://sesia.humnet.unipi.it/lexit

LexIt contains a vast array of information automatically extracted from
two large Italian corpora with state-of-the-art computational linguistic
methods:

- syntactic slots (subject, complements, modifiers, etc.) and
syntactic subcategorization frames represented as combinations of
syntactic slots;

- lexical sets containing the fillers realizing the syntactic slots of each
subcategorization frame;

- semantic classes to describe the selectional preferences of the
syntactic slots.

The LexIt interface allows the user to choose the part-of-speech of the
target lemma and the source corpus, and to explore the database
through five navigation paths:

- by target lemma
- by syntactic frame
- by argument slot
- by lexical filler and argument slot
- by semantic class

Currently, LexIt contains distributional profiles for Italian verbs and
nouns. Adjectives will be added soon. Thanks to the statistical data
available in LexIt, it is possible to analyze the combinatorial properties
of lexical items and the argument structure of predicates, by identifying
their most salient and prototypical distributional features.
