Abstract

The invention discloses a related word mining method. The method comprises: obtaining parallel sentence pairs expressing the same meaning with different expression forms based on large-scale user search behavior data; performing word segmentation processing on each set of parallel sentence pairs; performing word alignment processing on the parallel sentence pairs subjected to the word segmentation processing to obtain first aligned word pairs; calculating co-occurrence frequency of the first aligned word pairs; and determining the first aligned word pairs with the co-occurrence frequency higher than a predetermined threshold as related words. With the related word mining method, related words with higher relevancy can be mined, the retrieval word search range also can be expanded, and the probability of finding a better search result is increased. At the same time, the invention furthermore discloses a search method and a search system.
