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.8 p.application/pdfeng(c) Vila Rigat, Marta et al., 2011Tipologia (Lingüística)Corpus (Lingüística)Tractament del llenguatge natural (Informàtica)Lingüística computacionalParàfrasiTypology (Linguistics)Corpora (Linguistics)Natural language processing (Computer science)Computational linguisticsParaphraseinfo:eu-repo/semantics/article5931552013-12-03info:eu-repo/semantics/openAccess
