Abstract
We have been studying for the automatic recognition and extraction of metaphor expressions in practical sentences. This paper introduces our metaphorical judgment model for “Noun B like Noun A” expressions. “Noun B like Noun A” expressions are classified into two usages; simile and literality. To automatically judge whether a phrase is simile or literality, “Noun B like Noun A” expressions were classified into six patterns depending on the semantic information of a noun, and the metaphorical judgment model was constructed based on these patterns. When the “Noun B like Noun A” expressions from newspaper articles were judged by the model, and its judgment was compared with the correct judgment, it was approximately 80% correct. Thus, the model was found to be effective in the recognition of metaphor expressions in real-life situations.
