For instance , ( Lin and Pantel , 2001 ) acquire two-argument templates ( inference rules ) from corpora using an extended version of the distributional analysis in which paths in dependency trees that have similar arguments are taken to be close in meaning .

Because of the large , open domain corpora these systems deal with , coverage and robustness are key issues and much on the work on paraphrases in that domain is based on automatic learning techniques . For instance , ( Lin and Pantel , 2001 ) acquire two-argument templates ( inference rules ) from corpora using an extended version of the distributional analysis in which paths in dependency trees that have similar arguments are taken to be close in meaning . Similarly , ( Barzilay and Lee , 2003 ) and ( Shinyanma et al. , 2002 ) learn sentence level paraphrase templates from a corpus of news articles stemming from different news source .
