Abstract
This paper proposes a method of predicate paraphrasing using an ordinary dictionary, which replaces a predicate with an equivalent word or phrase in its dictionary definition. The ordinary dictionary does not contain sufficient information for three sub-tasks of predicate paraphrasing: resolution of predicate sense ambiguity, extraction of the equivalent word or phrase from the definition, and proper transformation of case markers. To compensate for the insufficiency, we employ case frame alignment of two predicates (a headword and its equivalent predicate), which produces the predicate paraphrasing patterns. The experimental result of paraphrasing 220 test sentences demonstrates the effectiveness of this method.
