Automatic paraphrasing is a transformation of expressions into semantically equivalent expressions within one language. For gener- ating a wider variety of phrasal paraphrases in Japanese, it is necessary to paraphrase functional expressions as well as content ex- pressions. We propose a method of para- phrasing of Japanese functional expressions using a dictionary with two hierarchies: a morphological hierarchy and a semantic hi- erarchy. Our system generates appropriate alternative expressions for 79% of source phrases in Japanese in an open test. It also accepts style and readability specifications.
