Composition of web services is a prominent feature of Service Oriented Architecture, for implementing business processes. Business processes may collaborate within or across organizations. During cross organizational collaborations, services are often heterogeneous thereby bringing challenges to composition. The two most popular types of web services are SOAP based web services and RESTful web ...
In order to facilitate agile business and support online partnership formation, many modern information systems are designed to support interoperability. This tendency has become mainstream with advancements in distributed systems and is supported by the Internet and industrial standards (or standard proposals) like XML, WSDL, SOAP and BPEL. However, increasing complexity of distributed informa...
Automated composition of Web services or the process of forming new value added Web services is one of the most promising challenges in the semantic Web service research area. Semantics is one of the key elements for the automated composition of Web services because such a process requires rich machine-understandable descriptions of services that can be shared. Semantics enables Web service to ...
The emergence of web services as a new technology supporting the future Web has motivated several researchers to investigate in this field. In addition, the possibility of selecting and integrating Web services, in or between organizations, is very useful for the improvement of their profitabilities. In such a case, we introduce the term of web service composition. In this paper, we propose an ...
In this dissertation, we present a novel approach for Web service mining. Web service mining is a new research discipline. It is different from conventional top down service composition approaches that are driven by specific search criteria. Web service mining starts with no such criteria and aims at the discovery of interesting and useful compositions of existing Web services. Web service mini...
Web Service composition has become increasingly important with more and more Web Services developed and deployed on the Web. It requires a formal and clear representation for analysis, design, and implementation. The Business Process Execution Language for Web Service (BPEL4WS), which is an XML-based language, provides a good basis to describe Web Service composition. However, it still lacks a ...
This paper presents a QoS (Quality of Service) based selection and composition model for semantic web services in which the negotiation is performed with all the discovered service providers and the negotiation results are used in the selection process. In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the ne...
Automation of Web service composition is one of the most interesting challenges facing the Semantic Web today. In this paper we propose a mean of performing automated Web service composition by exploiting semantic matchmaking betweenWeb service parameters (i.e., outputs and inputs) to enable their connection and interaction. The key idea is that the matchmaking enables, at run time, finding sem...
The state-of-art Web services composition approaches are facing more and more serious bottlenecks of effectiveness and stability with the increasing diversity and real-time requirements of applications, since new web service chain must be generated from “scratch” for each application. To break these bottlenecks, this paper presents a Min-Conflict Heuristic-Based Web Service Chain Reconfiguratio...
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...
