Dynamic Web service composition is a process of building a new value added service using available services to satisfy the requester’s complex functional need. In this paper we propose the broker based architecture for dynamic Web service composition. The broker plays a major role in effective and efficient discovery of Web services for the individual tasks of the complex need. The broker maint...

Service composition is an important mean for integrating the individual Web services to create new value added systems that satisfy complex requirements. However, it is challenging to guarantee the reliability of service composition in a distributed, dynamic and complex environment. This paper proposes an approach to constructing the reliable service composition. The underlying formalism is Pet...

Web services need to be orchestrated to achieve complex demand. However, existing approaches on Web service composition are mainly based on syntax match. It is very difficult to compose heterogeneous Web services with syntax in accord with function. Gradually, Petri net becomes a powerful system modeling and analysis tools research discrete event dynamic system. In order to solve this problem, ...

There are various approaches for QoS-based web service composition using GA (Genetic Algorithm). Most of them use the sum of the values of QoS properties times their weights as the fitness function of GA, to evaluate the QoS of service compositions. However, by using this function, the service composition calculated by GA has shortcomings. For example, response time of the produced service comp...

Automatic service composition may dramatically improve development efficiency of Web Service applications. This paper proposes an approach to automatically process semantic and dynamic service composition using Description Logics(DLs) and AI planning techniques. Services and service composition problems are formalized with DLs to provide well-defined semantics. Four relationships among services...

As Web services become widespread, many complex applications require service composition to cope with high scalability and heterogeneity. Centralized Web service composition approaches are not sufficient as they always limit the scalability and stability of the systems. How to efficiently compose and adapt Web services under decentralized environments has become a critical issue, and important ...

Services are preprocessed based on clustering techniques in the levels of function and similarity of services. Service clustering is modeled by means of the passing value indeterminacy of logic Petri nets. Thus service clustering can be described, and the services with indeterminacy parameters can be modeled formally. Thus service composition is investigated under the classified architecture of...

Service-Oriented Computing supports description, publication, discovery and composition of services to fulfil end-user needs. Yet, service composition processes commonly assume that service descriptions and user needs share the same abstraction level, and that services have been pre-designed to integrate. To release these strong assumptions and to augment the possibilities of composition, we ad...

With the widespread proliferation of web services, the demand on highly reliable and available services increases to satisfy business and personal needs. As the number of functionally similar web service increases on the Internet, Quality of Service (QoS) based web service selection and composition has gained much attention. However, the existing architectures for runtime service composition re...

A context-aware ubiquitous service composition technology is proposed. This can be used in both enterprise and consumer communication service environments. Because the context-awareness is the one of the most important factors in ubiquitous computing, it is insufficient in conventional service integration based on rigid interface design. The flexible service composition based on user context is...
