Semantic Web Services Query and Manipulation Language for Quality Attributes of WebServices

[摘要] The Web is moving toward a collection of interoperating Web services. Achieving this interoperability requires dynamic discovery of Web services on the bases of their capability. The capability of a service can be best determined by its functional description attributes, which describe the service interface such as input and output of the service, and quality attributes, which provide additional information to evaluate the service.This thesis defines an approach where these quality attributes can be advertised and queried by using DAML as the query, ontology, and service description language. As a core part of this system, we modify and extend an existing DAML query language. We develop this system as an extension of current Web service registries so our system will be fully synchronized with any available Web service registry.
