%X A new Web search strategy based on decision tree method in data mining was proposed. In this strategy, a decision tree was obtained by studying the Web pages sampled in advance. Then the tree was pruned to get the inherent regularity of the subject in the form of simplified boolean expression, on the basis of which the query was modified and forwarded to general search engines, and finally the searching results were got. The experiment performed indicated that for subject-specific Web search, the quality of query results improved obviously.
