Put the predicting query performance(PQP) into the query fusion and construct a new adaptive information retrieval system(QAAIR) based on performance analysis in the base of analyzing the method of PQP for IR system and expound the main technique. The experiment adopted testing data of TREC Web track show the method can improve the effectiveness of query and overcome the robust of information retrieval.
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...
Prediction query performance (PQP) has been recognized by the IR (Information Retrieval) community as an important capability for IR systems. This paper put forward pseudo prediction query performance in the base of analyzing PQP. The authors design a new IR method. The experiment adopted testing data of TREC Web Track shows the method can improve the effectiveness of query.
