The growing number of the Web Services available on the Web without explicit associated semantic descriptions raises a new and challenging research problem: How to discover efficiently the relevant Web Services that fulfill the user expectations. However, many services that are relevant to a specific user service request may not be considered during the… (More)
In this paper, we present the main related works according to Semantic Web Service Technology and we propose a new WSMO Goal based approach for the discovery of Web Services.
Semantic Web Services (SWSs) aim to improve the possibilities for automated discovery, composition and invocation of Web Services by providing ontology-based service descriptions expressed in a formal language. Several approaches have been driving the development of Semantic Web Service frameworks such as OWLS (Ontology Web Language for Services), WSMO (Web… (More)
With the greater number of Web Services (WSs) available on the internet, searching the appropriate WS that fulfills the user needs has become a major challenge. In this paper, we propose a Goal-based framework for Web Services (WSs) discovery. The framework employs matching algorithms and allows searching through a set of Semantic Web Services (SWS)s in… (More)
The Semantic Web Services (SWS) technology is used to describe the Web services' capabilities and content in a computer-interpretable language and improve the quality of existing tasks, such as Web Services discovery, invocation, composition and monitoring. This paper addresses the topic of defining a knowledge based system for representing Semantic Web… (More)
