Semantic Web Service Discovery

With the fast development of internet, the growing number of web services available on the Web raises new and challenging search problems: efficiently locating functionality-desired web services among numbers of web services and selecting a best one among large numbers of functionality-similar web services. While these just are the task of web service discovering. However, traditional web service discovering technology is done by keyword match based on the syntactic description of web service. Such web service discovering technology can not capture the semantic information of web service and is lack of intelligence, so it can not meet the growing demand of people. In order to get a better result of discovering, a more efficient and perfect web service discovering technology is needed. This is where the Semantic Web comes to play. The Semantic Web is an effort to facilitate the web resources with semantic descriptions. It is not a separate Web but an extension of current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation. Ideally, Web Services and the Semantic Web should support each other but there are still some gaps. The Semantic Web Service is an attempt to bridge the gap between Web Services and the Semantic Web. So Semantic-based Web Service Discovery is becoming a hot research topic. The researches show that the use of semantic description and ontology of web service can improve the result of service discoveringAutomatic Web Service Discovery is an automated process to locate the Web Services that match the client' s requirements appropriately. It is the basic issue of Semantic Web Services' research. This paper describes a model for flexible discovery of Semantic Web Services. The proposed approach has three main features compared with other approaches.Firstly, OWL-S and Reputation Ontology are used to describe the Web Services. As both a language and ontology, OWL-S is widely used to add...
