Multi-agent selection of multiple composite web services based on CBR method and driven by QoS

Many companies aim to use Web services to integrate heterogeneous or remote applications in SOA (Service Oriented Architecture) contexts. Indeed, one of the main assets of service-orientation is a composition to develop higher level services, so-called composite services, by re-using existing services. Since many available Web services provide overlapping or identical functionality, with different Quality of Service (QoS), a choice needs to be made to determine which services are to participate in a given composite service. However, for a composition, we can have different combinations and execution paths. Particularly, a composite service can generate different schemes that give various QoS scores.
