Demonstrating effective ranked XML keyword search with meaningful result display

In this paper, we demonstrate an effective ranked XML keyword search with meaningful result display. Our system, named ICRA, recognizes a set of object classes in XML data for result display, defines the matching semantics that meet user's search needs more precisely, captures the ID references in XML data to find more relevant results, and adopts novel ranking schemes. ICRA achieves both high result quality and high query flexibility in search and browsing. An online demo for DBLP data is available at http://xmldb.ddns.comp.nus.edu.sg/
