Most service composition approaches rely on top down decomposition of a problem and AI-style planning to assemble services into a meaningful whole, impeding reuse and flexibility. In contrast, our approach starts from declarative knowledge about the semantics of individual services and constructs a full-blown orchestration process that supports sequence, choice and parallelism. The approach, which...
Web services are software components developed to simplify machine-to-machine interaction over the Web. Many researches are targeted towards Web service standardization, and these efforts have significantly contributed towards improving functionality of Service Oriented Architecture (SOA). However, there are number of issues yet to be resolved. Among them, one of the major challenges is the standardization...
With the spread of Internet technologies, the severe competition among businesses, many organizations are moving towards integrating their services online. Service Oriented Architecture (SOA) has shown a potential features in facilitating and managing services integration and expose them through a Portal application. The marriage of these two new standards will definitely lead to a full fledge service...
Semantic Web Services discovery and composition: paths along workflows Web Services allow the composition of new services on top of existing, partial ones. Using standard languages, Semantic Web Services can provide the description of their input parameters and preconditions for execution, as well as the output and effects of their execution. The availability of such descriptions demand the investigation...
In the service collaboration field, there exists the need to combine two or more services together to fulfill a complex goal. Though service composition is an active research field, most of solutions are focused on Web services and lack of the consideration for business-level collaboration. In this paper we present a discovery architecture that supports business-level service composition. In our architecture,...
The process of semantic web service composition arranges several web services into one composite service to realize complex workflows with an exploitation of semantics. This paper proposes an approach to automatic semantic web service composition. Its advantage is good scalability regarding the complexity of user constraints and pre/post conditions. Based on these conditions it propagates the value...
The process of semantic Web service composition arranges several Web services into one composite service to realize complex workflows with an exploitation of semantics. This paper proposes a framework to automatic semantic Web service composition. Its advantage is that a huge amount of computation is performed during preprocessing and the composition approach is designed to exploit the parallel execution...
The paradigm of the composition of Web services to recognize this day considerable interest in Web technology in general and specifically distributed systems and/or distributed applications. The service-oriented architecture (SOA) have profitable B2B solutions, making best use of services already available on the Net. Existing work on the composition of dynamic Web services have shown that the description...
At present, Web services are created and updated on the fly. It has already beyond the human ability to analysis them and generate the composition plan manually. It is a problem that composing existing Web services automatically and dynamically according to userspsila request. A number of approaches have been proposed to tackle that problem. Most of them are inspired by the researches in cross-enterprise...
This paper proposes an automatic Web services composition method that satisfies the userpsilas request efficiently. Using the method, the available services in a local repository described in OWL-S are translated into a set of production rules, and the dependency rules of the Web services are established using interface matchmaking. We choose reasoning Petri nets (RPN) as the model of this set of...
The dynamic composition of atomic services to create a composite Web service is one of the problems of the Web service integration and is still at research level. In that context, selecting Web services with respect to user preferences is still vague. This paper addresses the problem of selecting a user preferred service for dynamic composition. The solution is based on emerging semantic Web service...
The need for having interoperable systems despite the presence of heterogeneous platforms has resulted in tremendous growth and acceptance of Web services in recent years. This success of Web services technology is fueling research efforts towards generalization into a science for service oriented computing (SOC). However, beyond the basic publish-find-bind model there is not much consensus yet on...
