With the increase of Web services popularity, due to its well established secure protocols, service providers are competing in the market with services that provide overlapping, if not similar, functionalities. To be attractive to consumers Web service providers must improve the quality of their services. When considering complex composite Web services, the selection of the most appropriate can...

With the growth of the Internet-of-Things and online Web services, more services with more capabilities are available to us. The ability to generate new, more useful services from existing ones has been the focus of much research for over a decade. The goal is, given a specification of the behavior of the target service, to build a controller, known as an orchestrator, that uses existing servic...

In a service-oriented environment services can be composed such that new value added services are created. The problem of service composition raises a number of specific issues like the openness of the environment and the large number of possible services. As currently such massive service deployments do not exist, the current techniques proposed for service composition are difficult to test an...

As a new application pattern, knowledge service has been rapidly developed in recent years. How to integrate the existent knowledge services to form a newly complex service is a popular research area. This paper presents a framework to support dynamically service composition. And then we focus on the global optimal model of knowledge services composition. The essence of the model is that the pr...

Composition of Web services has received much interest to support business-to-business or enterprise application integration. In our work, we build the composition method based on service interface description. Compared to previous work, our approach for composition only uses the information that is already available in service interface definitions. It does not require service providers descri...

Web service composition is a distributed model to construct new web service on top of existing primitive or other composite web services. Many research efforts have been made in web services composition and coordination. In such a scenario, an important issue is how to assess the degree of trustworthiness one can have about the web service composition, especially their performance and dependabi...

We investigate architectural properties required for supporting automatic service composition. First, composable service architecture will be described, based on modeling Web services as abstract machines supported by formally defined composition operators. Based on the proposed infrastructure we give several options for achieving automatic service composition by treating it as a search problem...

In order to achieve an adaptive and good performance service composition, this paper proposes a task-oriented web service discovery algorithm using semantic similarity for adaptive service composition. The approach divides the process of service composition into semantic discovery and functional matching and takes tasks as operation objects. A task-oriented web service discovery algorithm is de...
