Web services following distributed object computing technology like DCOM, CORBA provides remote procedure call mechanism based on XML-based open standard such as SOAP, WSDL, and UDDI, and it is spotlighted as means of integration and collaboration at e-business. Especially, UDDI is the Web services registry enabling to register and search Web services that takes charge of providing infrastructure for Web services. However, the existing UDDI has a few problems that searching process is very simple and it cannot provide information of Web services quality and quality-based retrieval. Therefore, this study suggests improved UDDI model that evaluates the Web services quality and use this information for searching.
