A Graph-Based Framework for Composition of Stateless Web Services

A QoS-Aware Hyper-graph Based Method of Semantic Service Composition

“…And our evaluation consists of two parts. First, we compare SUTB [4] with our method by the precision and composition time. Then we carry out some experiments on the test sets which are generated by the WSC 2009 Testset Generator to evaluate the method furthermore.…”

“…Some approaches, such as [5,6], tackle Web service composition problem via AI planning. On the other hand, some other researches [4,10] regards it as a graph search problem and solves it by shortest path, A*, etc. algorithms.…”

“…Therefore, semantic web is introduced into Web Service technologies to support dynamic and automated tasks such as discovery, composition and execution. In recent years, how to composite services automatically have drawn lots of research attentions [3][4][5][6][7][8][9]. In this paper we proposed a QoS(Quality of Service)-aware hyper-graph based method for semantic Web Service Composition.…”

Web Service Composition Using Service Maps

“…Different approaches graph [6] [9],Petrinet [10], Description logic [8],FSM [4] are used to generate composite services. To scale up the service composition RDBMS based approach is used in [7].…”

“…Each service provides certain set of functionalities and these are exposed to the external world by interfaces for service search. The existing service search approaches are based on these interface descriptions e.g I/O match [6][3] and protocol match [5]. When a single service does not satisfy search request, a set of services are combined to meet the need.…”
