Recommendation Framework for Service-Oriented Grid

Grid computing systems provide a virtual framework for sharing resources across organizational boundaries. The merging of Service Oriented Architecture (SOA) with the original Grid technology has resulted in the emergence of the Service Oriented Grid (SOG). The resources from various virtual organizations (VO) are packaged as "services" and offered to users in the form of Grid services. With the increasing use of SOG, service user is in a fix when having to make a choice from a set of services offering the same functionality. Hence service selection is one of the challenges to be addressed in Service Oriented Grid. In this paper we propose a framework for a recommendation system based on trust, reputation and QoS for the SOG with multi-VOs. This novel approach uses computation of trustworthiness of services by the mechanism of taking feedback directly from the service consumers and recommendations from other service providers.
