An Approach for Semantic Search by Matching RDF Graphs

Haiping Zhu, Jiwei Zhong, Jianming Li, and Yong Yu

The World Wide Web is developing rapidly, but neither recall nor precision of traditional search engines can satisfy the increasing demands of users. Presently, RDF is widely accepted as a standard for semantic representation of information on the Web, which makes possible the advanced search among web resources. In this paper, we introduce an approach for semantic search by matching RDF graphs. New similarity between RDF graphs is defined and ontologies on arcs as well as on nodes are employed. The implementation of a demonstration system on our method is currently in progress.
