CONQUER: A Methodology for Context-Aware Query Processing on the World Wide Web June 10, 2009

Professor Vijay Sugumaran from Oakland University, USA will be presenting this seminar from the University's Informatics Research Institute.

Abstract:
A major impediment to accurate information retrieval from the world wide web is the inability of search engines to incorporate semantics in the search process.

This research presents a methodology, CONQUER (CONtext-aware QUERy processing), that enhances the semantic content of Web queries using two complementary knowledge sources: lexicons and ontologies.

The methodology constructs a semantic net using the original query as a seed, and refines the net with terms from the two knowledge sources. The enhanced query, represented by the refined semantic net, can be executed by search engines. In this research, an intelligent semantic web retrieval architecture has been developed to automate the processing of a user's query while taking into account the query's context.

It uses a heuristic based methodology that combines techniques to support meaning based searches including natural language processing, ontology integration, semantic network processing, and agent based reasoning. The research, thus, provides a successful demonstration of the use of existing knowledge sources to enhance the semantic content of web queries.
