XML metadata retrieval based an approximately matching model
Liubo Ouyang · Jisuanji gongcheng · 2005
This thesis took apart the unordered label tree matching into tree structure matching and tree label semantic matching. By combined with the tree structure matching and semantic matching, the thesis changed the traditional tree matching algorithms into approximately matching, and a metadata retrieval method based on three-level tree approximately matching model was put forward. According to this new retrieval method, the accuracy and recall rates would be adjusted by different requirement of users. In the end, this thesis brought forward the retrieval process of XML-oriented metadata, and gave out the applied design of metadata approximately match. The results of experiments prove that the approximately matching model is feasible and efficient in the application of retrieval XML metadata.
