Aim at the low coverage of current hand-coded knowledge base used in the metaphor recognition, a Chinese nominal metaphor recognition method based on exploiting the online encyclopedia resource is proposed. A noun is represented as a page in the encyclopedia. Capture the world knowledge from the page of encyclopedia, calculates the relatedness between the pages of the two nouns in the nominal reference by applying information retrieval methods. The relatedness determines the reference is metaphorical or not. The experimental results shows that the accuracy of metaphorical/normal references recognition can reach 81.06% by using BaiduBaike. It supports the validity, efficiency of this method.
