| 抄録: | Traditional information retrieval model is based on the statistics, and all the keywords to the model are not assigned with weight values. So the precision of retrieval results is not high enough to satisfy users. A new information retrieval model is issued to evaluate the weight and similarity by adopting influence factors of keywords in XML documents and context knowledge. It is applied to an information retrieval system (XIIR) for domain-based XML documents retrieval. The experimental results show that the model is more effective in raising precision and recall rate than traditional models. At last, the development of information retrieval model is prospected. |
