--The use of web services has dominated software industry. Existing technologies of web services are extended to give value added customized services to customers through composition. Automated web service composition is a very challenging task. This paper proposed the solution of existing problems and proposed a technique by combination of interface based and functionality based rules. The pro...
Customizing the Composition of Web Services and Beyond Shirin Sohrabi Doctor of Philosophy Graduate Department of Computer Science University of Toronto 2012 Web services provide a standardized means of publishing diverse, distributed applications. Increasingly, corporations are providing services or programs within and between organizations either on corporate intranets or on the cloud. Many o...
For independent global constraints Web services composition problem, it is difficult to analyze the optimal composition plan. The study presents an optimization method of Web service composition with constraint using Fuzzy Petri Net (FPN) and Differential Evolution (DE), which can transforms solving the optimal service composition problem into locating the largest trust value of legal firing se...
In this paper, we propose an efficient QoS management approach for QoS-aware web service composition. In the approach, we classify web services according to theirs similarity and then design a QoS tree to manage the QoS the classified web services. Besides, by querying the managed QoS, we propose a QoS-aware web service composition via a particle swarm optimisation algorithm to perform fast web...
Web services are nowadays a popular technology used in practice when diverse software system integration is in demand. The ability to make some functionality available through the Web has inspiring consequences. The Web services provide features which are very interesting also from a research point of view. They are studied from several aspects to propose solutions allowing their more sophistic...
In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the negotiation-agreements generated from the negotiation can also be used in the selection process. This paper presents a semantic web service selection and composition model based upon this concept. The paper presents multi-agent negotiation based semantic w...
Web Service discovery and composition is one of the key objectives of Service Oriented Architecture (SOA) which provides a loosely-coupled environment and enables flexible assembly of existing web services. Service discovery plays a vital role in the overall process of the service discovery and composition. The Web Ontology Language for Services (OWL-S) has emerged as the de facto standard for ...
Automated Web service composition and automated Web service annotation could be seen as complimentary methodologies. While automated annotation allows to extract Web service semantics from existing WSDL documents, automated composition uses this semantics for integrating applications. Therefore applicability of both methodologies is essential for increasing the productivity of information syste...
Web services are an emerging paradigm aiming to offer the interoperability afforded by web applications combined with rich client interaction. Web service composition allows a distributed application to be constructed from a number of previously published web services. This component-based style of implementation offers many benefits to the developer, but the reliance of third party hardware an...
