A SEMANTIC-BASED WEB SERVICE RELATIONSHIP NETWORK SYSTEM

摘要

The invention discloses a semantic-based web service relationship network system. The web service relationship network is used for the semantic-based service discovery and (semi-) automatic service composition. Services to be processed by the web service relationship network come from the submitting services and the acquiring services of the network. The submitting service receives the service registration request passively, and the information is extracted and sent to the web service relationship network. The acquiring service actively uses the web crawler technique to acquire the description document of the service and adds the description document to the web service relationship network through the service registration interface. The composition service, which is automatically acquired according to the user's function description, is sent to the web service relationship network by the service registration. The invention is more convenient to process the publication of the web service, the semantic-based service discovery and the (semi-) automatic composition, and could be extended to be compatible with several service description languages. The invention composes the service ecological system with the available web services and improves the operations of services such as automatic composition, searching, and maintenance etc. by using the relationship of services.
