In this paper, we propose a framework to implement a self-adaptive goal-driven service composition based on context and QoS approach. According to our approach, every concrete composition is regarded as an instantiation of the goal abastract graph, which is regarded as the abstract composition. By means of incorporating, a feedback system, our approach can handle composition requests failures using...
In this paper, we present a user-centered approach, which ensures dynamic service discovery and composition. Besides, our proposed framework integrates self-adaptive mechanisms to adjust the service's execution to the user's context and the notion of the QoS in order to build a composite service or find services that fit a best. Additionally, our framework permits the re-composition of the composite...
With the growing number of web service availablein web, selecting web service that satisfies the users need isbecome more difficulties. So to deal with the problem, numerousapproaches are proposed. Some approaches are interested tointegrate the Quality of Service (QoS) to select the suitableservice. The QoS plays an important role in the discovery andselection process of web services within many similar...
Since the emergence of Web services and the diversity of user's devices, an emerging need for adapted web services appeared. In fact, users aim to find web services meeting their requests, contexts and desired QoS. In order to achieve this goal, we propose in this paper a framework to find and select adaptable web services. Our framework is named QoS-ASF and it is based on a multi-agent system.
