Extracting Paraphrases from a Parallel Corpus
نویسندگان
چکیده
While paraphrasing is critical both for interpretation and generation of natural language, current systems use manual or semi-automatic methods to collect paraphrases. We present an unsupervised learning algorithm for identification of paraphrases from a corpus of multiple English translations of the same source text. Our approach yields phrasal and single word lexical paraphrases as well as syntactic paraphrases.

Applicability Analysis of Corpus-derived Paraphrases toward Example-based Paraphrasing
Two kinds of paraphrases extracted from a bilingual parallel corpus were analyzed. One is from an adjectival predicate sentence to a non-adjectival one. The other is from a passive form to a non-passive form. The ability to extract paraphrases is strongly desired for paraphrasing studies. Although extracting paraphrases from multi-lingual parallel corpora is possible, the type of paraphrases ex...
متن کاملAutomatic paraphrasing based on parallel corpus for normalization
Abstract There are various ways to express the same meaning in natural language. This diversity causes difficulty in many fields of natural language processing. It can be reduced by normalization of synonymous expressions, which is done by replacing various synonymous expressions with a standard one. In this paper, we propose a method for extracting paraphrases from a parallel corpus automatica...
متن کاملExtracting Paraphrases from Definition Sentences on the Web
We propose an automatic method of extracting paraphrases from definition sentences, which are also automatically acquired from the Web. We observe that a huge number of concepts are defined in Web documents, and that the sentences that define the same concept tend to convey mostly the same information using different expressions and thus contain many paraphrases. We show that a large number of ...
متن کاملA Corpus-based Method for Extracting Paraphrases of Emotion Terms
Since paraphrasing is one of the crucial tasks in natural language understanding and generation, this paper introduces a novel technique to extract paraphrases for emotion terms, from non-parallel corpora. We present a bootstrapping technique for identifying paraphrases, starting with a small number of seeds. WordNet Affect emotion words are used as seeds. The bootstrapping approach learns extr...
متن کاملLearning Sentential Paraphrases from Bilingual Parallel Corpora for Text-to-Text Generation
Previous work has shown that high quality phrasal paraphrases can be extracted from bilingual parallel corpora. However, it is not clear whether bitexts are an appropriate resource for extracting more sophisticated sentential paraphrases, which are more obviously learnable from monolingual parallel corpora. We extend bilingual paraphrase extraction to syntactic paraphrases and demonstrate its a...
