Automatic Paraphrasing of Japanese Functional Expressions Using a Hierarchically Organized Dictionary
نویسندگان
چکیده
Automatic paraphrasing is a transformation of expressions into semantically equivalent expressions within one language. For generating a wider variety of phrasal paraphrases in Japanese, it is necessary to paraphrase functional expressions as well as content expressions. We propose a method of paraphrasing of Japanese functional expressions using a dictionary with two hierarchies: a morphological hierarchy and a semantic hierarchy. Our system generates appropriate alternative expressions for 79% of source phrases in Japanese in an open test. It also accepts style and readability specifications.
