The invention discloses a Chinese word relevancy calculation method and device based on Wikipedia concept vectors. The method comprises the steps that 1, a Wikipedia Dump service site acquires raw corpora, conducts normalized treatment on the raw corpora and generates a Wikipedia basic corpus; 2, concept labeling and expanding are conducted, and a Wikipedia concept corpus is built; 3, according to the Wikipedia concept corpus, the concept vectors are trained; 4, according to the Wikipedia, a word concept set of word pairs to be compared is acquired; 5, the similarities of the concept vectors corresponding to all the concept pairs in the cartesian product of the concept set are calculated, and the largest value is used as the similarity of the word pairs to be compared. By using the Chinese word relevancy calculation method and device based on the Wikipedia concept vectors, word concept information which is contained in the Wikipedia can be sufficiently excavated so that the word concept vectors can be generated, and the word similarity can be calculated more accurately and effectively.
