XSEarch: A Semantic Search Engine for XML Sara Cohen, Jonathan Mamou, Yaron Kanza, and Yehoshua Sagiv   View Paper (PDF)   Return to Internet/WWW (Session A1) Abstract XSEarch, a semantic search engine for XML, is presented. XSEarch has a simple query lan- guage, suitable for a naive user. It returns se- mantically related document fragments that satisfy the user's query. Query answers are ranked using extended information-retrieval techniques and are generated in an order sim- ilar to the ranking. Advanced indexing tech- niques were developed to facilitate efficient im- plementation of XSEarch. The performance of the different techniques as well as the re- call and the precision were measured exper- imentally. These experiments indicate that XSEarch is efficient, scalable and ranks qual- ity results highly. ©2004 Association for Computing Machinery
