Abstract

Existing LCA-based XML keyword search approaches are not aware of the significance of using semantics of object to improve search efficiency and quality during LCA-based computation. In this paper, we propose a novel object-oriented approach for XML keyword search. In each step of our approach, i.e., labeling an XML document, constructing related indexes and searching for relevant LCA nodes, we use the semantics of object. We theoretically and experimentally show the superiority our semantic approach over existing approaches.
