摘要：This paper proposes a method to discover definitoon patterns automatically from an ordinary dictionary. A definition pattern, which is frequently used to describe words and concepts in a ordinary dictionary, determines a set of similar words and can be used as a template to clarify distinctions among them. To discover these definition patterns, we convert definition sentences into tree structures, and compress them using the MDL principle. The experiment on a Japanese children dictionary is reported, showing the effectiveness of our method.
