Discovering a service which satisfies a request sufficiently is a major issue in any application process. As a result, the motivation to develop a powerful and customizable matchmaking engine becomes a very important criterion. Using semantic information for the matchmaking process achieves better results than syntactic type matchmaking. In this paper an ontology based service discovery tool, called OntoServiceMatchmaker, is presented which performs flexible semantic matches of customized service requests. The matchmaking engine is capable of parsing DAML+OIL marked properties and allows the user to customize the matchmaking process accordingly. This engine utilizes current semantic matchmaking techniques to perform the service discovery. The description properties and functional attributes of the ontology are properties for the matching values. These properties found by the ontology parser and reasoned by the inference engine serve for the matchmaking process as input variables. The final selection is done by matching the customized service request with the actual service advertisements provided in a registry.
