Abstract

Dynamic service composition provides the potential for future applications to adapt to various user preferences and contexts. Despite its difficulties, dynamic service composition provides several benefits, namely, flexibility, adaptability, and availability. However, existing dynamic service composition systems lack extensibility and understandability. Also some systems cannot support operation dependency and soft-state information. To overcome the problems of the existing systems, this paper proposes a new component model called Component Service Model with Semantics, or CoSMoS. CoSMoS resolves the problems of the existingsystems by applying semantic graphs, ontologies and an object-oriented model. This paper describes the structure of CoSMoS and shows how dynamic service composition can be implemented using CoSMoS.
