Applicability Analysis of Corpus-derived Paraphrases toward Example-based Paraphrasing
Kiyonori Ohtake, Kazuhide Yamamoto · 2003
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 extracted is unknown. We discovered what types of examples can be obtained, and what types of paraphrasing will be available for the two kinds of paraphrases.
