An Architecture for Recommendation Based Service Mediation

Resource brokering is a crucial activity in Grid infrastructures and other environments with dynamic resource selection. The mediation between resource requirements and available resources relies on adequate resource description, which becomes a special challenge when the resources are (Grid) services. In addition to the description of service semantics, service quality is another useful selection criteria in effective service mediation. Inspired by the success of communityand usage-pattern-based filtering and recommendation systems for targeted information access, this paper discusses automatic and manual service rating as an option for judging service quality. Such ratings can contribute to targeted service selection and complement the mediation based on service semantics.
