RDF based Integrated Information Retrieval in grid computing environment

The information explosion calls for adequate and efficient approaches to information retrieval. Integrated Information Retrieval (IIR) in grid computing environment is becoming more and more attractive for integration and share of heterogeneous resource to provide users integrated retrieval services. This paper proposes IIR service infrastructure on grid platform, GIIRS, which used Resource Description Framework (RDF) as data representation specification. And we designed a query mechanism to implement IIR of heterogeneous and semi-structured web data. The GIIRS can be easily deployed on grid platform and have feature of semantic interoperability.
