Context-aware semantic Web service discovery protocol

subject

description

The Web of today represents a broad space where users research, discover and share information. In this context, the process of Web service discovery plays a significant role. Indeed, such process allows linking the information published by service providers and the requests of users, looking for information. Generally, such process involves text or keyword-based techniques. Still, this kind of discovery fails in retrieving only relevant information. Our approach is to design a more " intelligent " system that allows using a knowledge base during the service discovery process, as it is done in the Semantic Web vision. This thesis presents a framework for semantic Web service discovery using non-functional service characteristics. The framework relies on the Web Ontology Language for Services (OWL-S) to design a template for describing non-functional service parameters in a way that facilitates service discovery. Our model is designed to facilitate the discovery of semantic Web services. This service description model is used as a core for designing the interfaces and the querries. Two interfaces are developped : one for the service providers, and one for the final users. The search algorithm presented in this thesis is designed to maximize precision and completeness of service discovery.
