| Abstract: | In order to apply all-weighted association rules mining technique to information retrieval,a novel information retrieval model was introduced based on all-weighted association rules mining and query expansion in this paper.Its designing conception and algorithm were expounded,some key technologies for implementation were also expatiated.The results of the experiment show that the model proposed is effective and improves the performance of information retrieval with superior applied value of practice as well... |
| Keywords: | Information retrieval Query expansion All-weighted item Association rule |
