Public Deployment of Semantic Service Matchmaker with UDDI Business Registry

Public deployment of the semantic service matchmaker to a UDDI registry for half a year is shown in this paper. UDDI is a standard registry for Web Services, but if we consider it a search engine, its functionality is limited to a keyword search. Therefore, the Matchmaker was developed to enhance UDDI by service capability matching. Then, we have deployed the Matchmaker to one of four official UDDI registries operated by NTT-Communications since September 2003. In this paper, we first introduce the Matchmaker with UDDI, and illustrate client tools which lower the threshold of use of semantics. Then, we evaluate this deployment by benchmarks in terms of performance and functionality. Finally, we discuss user requirements obtained by two ways: questionnaire and observation of search behaviour.
