一种考虑标签语义的XML关键字查询算法
Effective XML keyword search with considering semantics of tags
摘要
Abstract
Notions of information unit （IU） and IU feature of XML （eXtensible markup language） documents were given. By taking IUs and IU features as candidate search results and the tags respec- tively, a semantic ranking strategy based on TF IDF （term frequency ＊ inverse document frequen- cy） model was proposed based on the structural semantics, which took account of both structures and contents in search results. The ranking strategy could prejudge the influence of IU features, and the influence was used to measure the relatedness of same keyword located in different IU features. Final- ly, the proposed technique was implemented by the search engine named XRIU （XML ranking infor- mation unit）. The extensive experiments demonstrate the effectiveness and efficiency of the approach.关键词
