Abstract  

This paper chooses corpus, definitions dictionaries and users’ query logs as contexts to extract the relevance terms. The experiment results show that the overlap ratio of results in different contexts is very low. So, it is necessary to integrate the different results. All of the relevance terms are integrated to a relevance table through direct integration.
Key words： Relevance term      Multi-context      Corpus      Definitions dictionary      Query log
