: ''For the linguistics definition, see [[paraphrase]].''

'''Paraphrase''' or '''Paraphrasing''' in [[computational linguistics]] is the [[natural language processing]] task of recognizingdetecting and generating [[paraphrase|paraphrases]].

Applications of paraphrasing are varied including information retrieval, question answering, text summarization, and plagiarism detection.<ref name=Socher /> Paraphrasing is also useful in the evaluation of [[machine translation]]<ref name=Callison>{{cite conference|last=Callison-Burch|first=Chris|title=Syntactic Constraints on Paraphrases Extracted from Parallel Corpora|book-title=EMNLP '08 Proceedings of the Conference on Empierical Methods in Natural Language Processing|date=October 25-27, 2008|place=Honolulu, Hawaii|pages=196-205|url=https://dl.acm.org/citation.cfm?id=1613743}}</ref>, as well as generation of new samples to expand existing corpora.<ref name=Barzilay />

Overview of applications and uses

Paraphrase models are often trained through the usage of [[parallel corpora|parallel text]] such as news articles covering the same incident or translations of novels. Since a desired output is not given, the training of paraphrase models is an instance of [[unsupervised learning]].
