Collaborative ranking of grid-enabled workflow service providers

Service Oriented Architecture (SOA) and Grid computing are very hot research topics, nowadays. While Grid computing is aimed at sharing dynamically heterogeneous resources, SOAs is a meta-architectural style that enable business flexibility in an interoperable way. There is a growing consensus that SOA(s) and Grid(s) might be beneficial to each other. In Grid-based SOAs a central role is played by tools for the publishing/discovering of services (resources). This work presents SPRanker (Service Provider Ranker): a service discovery tool that is able to retrieve providers from partially specified service descriptions. It ranks providers found on the basis of an Information Retrieval-based score formula that takes into account judgments expressed collaboratively by past service users. Categories and Subject Descriptors C.4 [Performance of Systems]: Measurement Techniques; D.2.10 [Software Engineering]: Design General Terms Performance, Design, Algorithms. Keywords SLA, QoS, SOA, Grid, I...
