Information Retrieval Using Xquery Processing Techniques

In recent years, the extraction of data from XML documents is an important issue for XML research anddevelopment. Fuzzy processing techniques have been proposed for flexible querying to Native XMLDatabases. We propose the fuzzy XQuery processing techniques for Native XML database systems, wherethe weights of attributes can be described by linguistic terms represented by fuzzy numbers. The proposedfuzzy XQuery processing techniques allow the users to use linguistic terms in the XQueries representedby fuzzy sets. The proposed Fuzzy XQuery processing applies the arithmetic operations of fuzzy sets. Theproposed fuzzy query processing techniques can deal with the users’ fuzzy queries in a more flexible andmore intelligent manner. Our proposed research work would be a new step towards a more flexibleXQuery language for Native XML Databases.
