The automated composition of Web services is one of the most promising ideas and at the same time one of the most challenging research area for the taking off of service-oriented applications. It is widely recognised that one of the key elements for the automated composition of Web services is semantics, i.e. unambiguous descriptions of Web services(More)
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(More)
One of the challenging problems that web service technology faces is the ability to effectively discover services based on their capabilities. We present an approach to tackle this problem in the context of description logics (DL). We formalize service discovery as a new instance of the problem of rewriting concepts using terminologies. We call this new(More)
The semantic web promises to bring automation to the areas of web service selection, discovery, composition, invocation. In this paper we introduce a means of facilitating automation of web service composition by exploiting semantic matchmaking between web service parameters (i.e., outputs and inputs) to enable their connections and interactions. The idea(More)
Automation of Web service composition i.e., the process of forming new value added Web services is one of the most promising challenges in Web service research area. Such an automation does not involve only a richer semantic for Web service description but also reasoning processes about those descriptions. Semantics is supposed to be one of the key elements(More)
We investigate the problem of dynamic discovery of e-services, important in the loosely coupled vision of e-commerce. We show that it can be viewed as a new important reasoning technique in Description Logics: it can be viewed as a new instance of the problem of rewriting concepts using terminologies which generalizes problems such as rewriting queries(More)
Most of the work on automated semantic Web service composition has focused so far on two main levels of composition i.e., functional level and process level composition (respectively FLC and PLC from now). The former level of composition considered Web services as atomic components that can be executed in a single request-response step whereas the latter(More)
