Abstract
Web services enable seamless application integration over the network regardless of programming language or operating system. A critical factor to the overall utility of Web services is an efficient discovery mechanism. In this paper, limitations of typical UDDI registry are analyzed. We propose a novel decentralized Web services registry infrastructure. We extract three levels metadata from Web services description. These metadata are annotated with service ontology, which acts as the bridge of P2P (peer to peer) and Web services. We have discussed multi-level Web services discovery under this infrastructure. Our experiment results testify that this infrastructure can effectively overcome bottlenecks of traditional UDDI registry. The evaluation shows that WordNet lexical dictionary facilitated and composite Web services discovery excel notably with large amounts of services.
