With the development of web service, the number of applications based on web service is increasing rapidly in recent years. More and more attention has been drawn to web service because of its convenience and platform-independence. In the few past years, UDDI is a common mechanism of publishing services in industrial applications. However, there are still no official standards which are recommended by W3C about how to publish and discover services. This paper proposes a method based on program slicing to publish and discover web services. The technology introduced in this paper is to add dependences between services into the UDDI registry center when services are published. A service dependence graph will be generated according to the dependences between services recorded in the UDDI registry center. Through implementing slicing operation on such a service dependence graph, a service and the services which it depends on will be discovered at the same time. The results of experiments show that our methods of web service publishing and discovery are feasible.
