Hybrid Registry for Semantic Web Services based on SWSQT

The registry of Web Services is a cornerstone for service-oriented architecture and constitutes a critical resource for web services. However, whether the traditional UDDI or its extension based on semantic, has not resolve the issue. The centralized Semantic Web Service Query Tree (SWSQT) is an efficiency service registry which can be dynamically built by service publishing process. The relationships of registered web services will be stored in SWSQT data model so that the large number of ontology reasoning can be avoid at service query state. But the performance of SWSQT will be decreased under the number of services rapidly growth for its centralized architecture. In this paper it proposes a hybrid web service registry based on SWSQT. It can resolve several deficiencies of SWSQT and the experiment has further showed its feasibility and efficiency.
