Semantic Query Processing on Xml
In this paper Semantic Query Processing on XML and Keyword search using CR (Coherency Ranking) is presented. Keyword search is a user friendly mechanism for retrieving XML data in web and scientific applications. An intuitively compelling but vaguely defined goal is to identify matches to query keywords that are relevant to the user. However, it is hard to directly evaluate the relevance of query results due to the inherent ambiguity of search semantics. As an effective search method to retrieve useful information, keyword search has gotten a great success in IR field.
