Abstract
A metaphor typically takes a form "A is B". This study researches the metaphors formed as above and propose a model which understand a metaphoric expression based on relevance theory. In relevance theory a metaphor is paraphrased by utterances, assumptions and implicatures.And an implicature is made from utterances, assumptions of a listener and their deductions.
In this study, first we extracted knowledge about the utterance from a news corpus and generated assumptions. Next we obtained implicatures operating the utterances and the assumptions. Third we chose the best paraphrase of the metaphors calculating the relevancies of implicatures and the utterances. We used a co-occurrence degree as a
relevance degree. Forth we evaluated the proposed model simulating
some metaphors.
