Web Service Composition WSC problems can be considered as a service matching problem, which means that the output parameters of a Web service can be used as inputs of another one. However, when a very large number of Web services are deployed in the environment, the service composition has become sophisticated and complicated process. In this study, we proposed a novel cost-effective Web servic...

In current service-oriented applications, each individual Web service usually cannot satisfy users’ requests for Web services, but the functionalities of different Web services may be integrated to accomplish requested task. This process is called Web service composition, and the resulted service is called composite Web service. The discovery and composition of Web services are two important re...

This paper presents a dynamic Web service composition algorithm based on description logic. Each input or output of the Web service request is regarded as a concept of description logic and according to the semantic similarity between concepts given the five types of description logic, we study on the dynamic composition algorithm based on service. Because the factors of service semantics and q...

The Web service composition problem involves the creation of a choreographer that provides the interaction between a set of component services to realize a goal service. Several methods have been proposed and developed to address this problem. In this paper, we consider those scenarios where the composition process may fail due to incomplete specification of goal service requirements or due to ...

Service composition is popular for composing a set of existing services to provide complex services. With the increasing number of services deployed in cloud computing environments, many service providers have started to offer candidate services with equivalent functionality but different Quality of Service (QoS) levels. Therefore, QoS-aware service composition has drawn extensive attention. Mo...

The increasing availability of web services within an organization and on the Web demands for efficient search and composition mechanisms to find services satisfying user requirements. Often consumers may be unaware of exact service names that’s fixed by service providers. Rather consumers being well aware of their requirements would like to search a service based on their commitments(inputs) a...

This letter presents a new approach to provide interdomain service compositions for OSGi environments. Our proposal of remote wire objects extends OSGi’s wiring capability across the framework boundaries, so that even remote services can join in the composition. Hence, a better composition is made possible with a richer set of candidate services from foreign domains. key words: service composit...

Cloud computing is an emerging internetbased paradigm of rendering services on payas -per -use basis. Increasing growth of cloud service providers and services creates the need to provide a tool for retrieval of the high-quality optimal cloud services composition with relevance to the user priorities. Quality of Service rankings provides valuable information for making optimal cloud service sel...

In this paper, we present an approach to solve the problem of secure execution of semantic web service composition plans. The integrated components of this approach include our OWL-S service matchmaker, OWLS-MX, the service composition planner, OWLS-XPlan, and the security checker module for formally verifying the compliance of the created composition plan to be executed with given data and ser...

The task of automatically composing Web services involves two main composition processes, vertical and horizontal composition. Vertical composition consists of defining an appropriate combination of simple processes to perform a composition task. Horizontal composition process consists of determining the most appropriate Web service, from among a set of functionally equivalent ones for each com...
