Towards runtime discovery, selection and composition of semantic services

摘要: Service-orientation is gaining momentum in distributed software applications, mainly because it facilitates interoperability and allows application designers to abstract from underlying implementation technologies. Service composition has been acknowledged as a promising approach create composite services that are capable of supporting service user needs, possibly by personalising the delivery through use context information or preferences. In this paper we discuss challenges automatic composition, present DynamiCoS, which novel framework aims at on-demand runtime for benefit end-users. We define DynamiCoS based on life-cycle. Framework mechanisms introduced tackle each phases requirements Semantic used our enable reasoning requests issued end-users, making possible automate discovery, selection composition. validate with prototype have built order experiment designed. The was evaluated testing environment using some case scenarios. results evaluation give evidences feasibility support also show benefits semantic-based frameworks particularly end-users who will be able more control process.
