The perfect composition of atomic services to provide users with services through applying qualitative parameters is very important. As expected, web services with similar features lead to competition among the service providers. The key challenge to find an appropriate web service for composition occurs when multiple aspects of quality (such as response time, cost, etc.) are considered in the ...

Web services are a popular technology used when diverse software system integration is in demand. The ability to make some functionality available through the Web has inspiring consequences. One of the intensively researched areas is the study how Web services can be used to dynamically create a functionality, based on the actual requirements. The basic idea is that multiple Web services can be...

A Web service composition is an interconnected set of multiple specialized Web service operations, which complement each other to offer an improved tool capable of solving more complex problems. Manual design and implementation of Web service compositions are among the most difficult and error prone tasks. To face this complexity and to reduce errors at design time, the developer can alternativ...

Due to the rapid development of Web technologies, Internet applications increasingly use different programming languages and platforms. Web services technologies were introduced to ease the integration of applications on heterogeneous platforms. The quality of Web services has received much attention as it relates to the service discovery process. However, less work has been done on issues rela...

The current standards for web service composition, e.g. BPEL. neither cater for dynamic service composition nor for dynamic business configuration. Our firm belief is that business processes can be built dynamically by composing web services in a model driven fashion where the design process is controlled and governed by a series of business rules. In this paper we examine the functional requir...

Semantic web service composition constitutes the phases namely specification, matchmaking, planning, validation, discovery and execution. As web service composition is categorised as an AI planning problem, the objective of this paper is to propose a fluent calculus approach for the planning phase of the semantic web service composition. Among various methods to solve the AI planning problem, l...

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 ...

Web service composition is an important reuse way of service resources, through which large scale and complex applications based on Internet can get the newer and more reliable resources among the distributed nodes. An important challenge for web services composition is how to ensure the correctness and reliability of the composition process. CPN(Colored Petri Net)as a formal modeling and verif...

In several scenarios, Semantic Web technologies are gaining momentum as the most promising ones to address the issue of integrating services among different entities, possibly belonging to different location. In particular, Semantic Web Service composition can be used when no individual available service can satisfy a specific client request, but (parts of) available services can be composed an...

Recently, Web Services Composition is receiving significant amount of interest as an important strategy to allow Business-toBusiness collaboration. The current Web Services composition solutions are inherently unreliable, so how to deliver reliable Web Services composition over unreliable web services is a significant and challenging problem. In this paper, we propose a framework for reliable m...
