Service Oriented Computing provides us with an opportunity to build distributed applications by invoking and selecting suitable services. In this paper we attempt to select context aware service and apply this to medical emergency scenario. This paper proposes an approach to select web services based on user context. Experimental results demonstrate that proposed method provides reliable solution...
With the rapid development of Web 2.0 and its related technologies, more and more end-users start to participate in the development of World Wide Web. Yet, not enough attention from both academics and industries has been paid to allowing them to compose services to assist their daily work. This is mainly due to the lack of a high-level abstraction that defines what concepts, functions, and system...
After the vision of Mark Wieser, and the advent of 3G connection with a large number of mobile computing devices(PDAs, Smartphones, Tablet, etc.) that have democratized access to information anywhere, we live in a new era of ubiquity where a set of services are offered in our environments. In this work we try to review the conception, discovery and composition of these services called pervasive in...
Combining existing services to create new pervasive computing services involves special design considerations, including context awareness, contingency management, device heterogeneity, and user empowerment. Service composition is a natural concept around which to structure pervasive systems and individuate parts of them that are suitable for contingency management, application, storage, and so on...
Dynamic description logic (DDL) is among the few emerging service composition solutions through logical reasoning. To overcome low efficiency and lacking context-aware support of DDL reasoning, we propose a new DDL-based service composition model, which supports context-based service pre-filtering over DDL reasoning space. The pre-filtering runs under the BPEL workflow and a distributed reasoning...
