In this paper, we present a critical analysis of the state of the art in the definition and typologies of paraphrasing. This analysis shows that there exists no characterization of paraphrasing that is comprehensive, linguistically based and computationally tractable at the same time. The following sets out to define and delimit the concept on the basis of the propositional content. We present a general, inclusive and computationally oriented typology of the linguistic mechanisms that give rise to form variations between paraphrase pairs. © 2011 Sociedad Española para el Procesamiento del Lenguaje Natural.

AnCora-Net is a multilingual verbal lexicon built from the mapping of the Catalan and Spanish AnCora-Verb verbal lexicons into the English Unified Verb Index. The Unified Verb Index combines different sources of knowledge for English of wide coverage, which are a referent in semantic representation. The integration of our resources to the Unified Verb Index will enrich the contents of AnCora-Verb lexicons with semantic information coded for English. In the same way, the Unified Verb Index will be also related to equivalent verbs in another languages giving rise a multilingual resource that can be useful for comparative studies. © 2011 Sociedad Española Para el Procesamiento del Lenguaje Natural.
