| Nowadays, there are numerous Web services with specific capabilities within various networks, which can be used by mobile users. How to find a suitable service is a challenging task for a user and matchmaking is the key for the service discovery. In this paper we propose a matching algorithm measuring the similarity of the request with each of the advertised services based on OWL-S. As a description language of semantic Web services, OWL-S increases flexibility of Web service description, enriches expressiveness and provides a capability-based mechanism of Web service discovery. In order to obtain a precise matching result the user profile is taken into account in the presented algorithm. The proposed technique is applied to a sample test and experimental results are presented demonstrating the effectiveness of the idea. |
