Relevance measures for XML information retrieval

摘要: In recent years, a lot of work has been carried out to develop efficient methods for storing and querying XML data. Most the proposals have approached subject from database point view, i.e., they primarily aimed at providing exact matching capabilities. The problem can, however, also be addressed as an information-retrieval problem, which obviously introduces some challenges, such need relevance ranking. vast majority previous based ranking on content and, furthermore, if structural properties were taken into account, only containment relationships considered. this paper, we focus results their aim supporting wide range operations, operations preceding/following relationships. Our method is fuzzy interpretation XPath query language discussed in paper. Finally, discuss relational implementation our model present experiments.
