Abstract:The Purchase Order Mediation scenario of the Semantic Web Service challenge describes an interoperability problem, in which two companies want to do business, and need to integrate their IT systems. Within the A-MUSE project, a solution to this problem is devised that uses ontologies to describe the two IT systems. This solution requires a tool that can create mappings between these two ontologies, and use these mappings to generate the necessary data transformations. This master thesis describes the research and development process that resulted in the creation of that tool. A state-of-the-art survey was conducted which resulted in an overview of existing ontology matching algorithms and mapping tools. These findings confirmed that there is currently no tool that can readily be used, and provided the necessary knowledge to start the development of a mapping editor. The resulting editor is capable of loading two ontologies that are expressed using the Web Ontology Language (OWL). The user of the editor can create mapping relations between classes and properties of the two ontologies, and provide additional information for each of these mappings. Based on the mappings, the tool can generate transformation code. This code is then used by other tools that are part of the solution. These tools perform the necessary translations of the messages that are exchanged between the two systems that have to be mediated, such that the systems can communicate with each other.
