An Ontological Framework for Large-Scale Grid Resource Discovery
Juan Li, Son T. Vuong · Proceedings - IEEE Symposium on Computers and Communications/IEEE Symposium on Computers and Communications · 2007
This paper presents GOIDS (Grid Ontological Integration and Discovery System), a comprehensive architecture for resource sharing and discovery in large-scale grids, where nodes integrate local ontologies to expand semantic knowledge of shared grid resources. A peer-to-peer based ontological directory service is used to facilitate the formation of the semantic small-world ontological communities. Ontological communities help prune the searching space and reduce the cost of searching. Inside communities, resource knowledge is integrated between nodes, and a DHT overlay is used for knowledge dissemination and discovery. This framework architecture improves interoperability among grid participants and aids efficient resource discovery through an expressive query language.
