TargetSearch: A ranking friendly XML keyword search engine

This demo illustrates an XML search engine TargetSearch that addresses an open problem in XML keyword search: given relevant matches to keywords, how to compose query results properly so that they can be effectively ranked and easily digested by users. The approaches adopted in the literature generate either overwhelmingly large results or fragmentary results, both of which may cause the ranking schemes to be ineffective. Intuitively, each query has a search target and each result should contain exactly one instance of the search target along with its evidence. We developed TargetSearch which composes atomic and intact query results driven by users´ search targets.
