Summary:Recently, the volume of Web information and the number of user accesses have increased rapidly. Static information can be retrieved by search engines whereas dynamic information may need special programs called Web services. Since each web service is specialized on its source, the attendance of complex user necessities requires the composition of several services. Thus, we need an efficient way of both locating the best services on the Web, and composing them adequately in order to solve complex problems. This paper presents a tool that discovers web services based on ontologies. It also realizes sequential and parallel composition and optimizes the result set based on domain specific attributes of service providers.
