Effective XML Keyword Search Algorithm for Meaningful Return Information

With the XML becomes a de-facto standard for exchanging and presenting information, the study on XML keyword search has become the focus of information retrieval. Several recent studies have finished the effective XML keyword search, but not all approach is effective in identifying return information, not all search result is satisfactory to user. In order to reduce the burden of user and satisfy user´s requirement, in this paper, we construct a kind of specific data indexes, and propose an effective XML keyword search algorithm which is designed for meaningful and useful return information. A large number of experiments show that the algorithm is efficient and effective.
