The article deals with the Extended Qualia Structure and predicative representation implemented in the semantic layer of the PAROLE/SIMPLE/ CLIPS lexicon, an Italian lexical resource for computational applications, mainly based on Generative Lexicon. The Extended Qualia Structure is a component of the model that allows the encoding of the complex and multifaceted nature of word senses. The advantages of Qualia-based representation and the potentialities the extended framework provides in capturing, combining and making linguistic information computationally usable will be presented. The predicative representation consists in the definition of a lexical predicate, its argument structure and selectional restrictions. The profits of this way of representing lexical information, which are, above all, the high degree of cohesion among entries semantically linked and an effective power in retrieving information will be shown. The links between a predicate and word senses and the mapping of a semantic predicate on to the syntactic frame will be also described, stressing how they can also be calculated by an automatic system. The reader will be guided in a route around the lexical data of a portion of semantic space, using as a track the various meaning dimensions the Extended Qualia Structure gives access to, and the several possible links between predicate, word-senses and syntax.
