In this paper, we analyse the performance of Tree Edit Distance as a paraphrase representation baseline. Our experiments using Edit Distance Textual Entailment Suite show that, as Tree Edit Distance consists of a purely syntactic approach, paraphrase alternations not based on structural reorganizations do not find an adequate representation. They also show that there is much scope for better modelling of the way trees are aligned.7 p.application/pdfeng(c) Vila Rigat, Marta et al., 2012ParàfrasiLingüística computacionalTractament del llenguatge natural (Informàtica)SintaxiParaphraseComputational linguisticsNatural language processing (Computer science)Syntaxinfo:eu-repo/semantics/article6192162013-12-02info:eu-repo/semantics/openAccess
