Abstract
In order to quickly and accurately using mass information in the deep Web database. According to the characteristics of the deep Web: large-scale, dynamic and heterogeneity. Put forward one new query fusion method based on the prediction query performance (PQP) for the first time. And put forward a new pseudo prediction query performance method. Adopted testing data of UIUC. The experiment show the method can improve the effectiveness of query.
