Free registration required

Executive Summary

Keyword search techniques which use advantages of XML structure make it simpler for ordinary users to query XML databases, but latest approaches to processing these queries depend on heuristics that are ultimately ad hoc. These approaches often retrieve not correct answers, overlook appropriate answers, and cannot rank answers properly. To remove these problems for data-centric XML, the authors propose enhanced coherency ranking, a domain and database design-independent ranking method for XML keyword queries that is based on an extension of the concept of mutual information. Keyword search is widely recognized as a best way to retrieve information from XML data.
