Interactive Data Integration with MappingAssistant

Due to the heterogeneity of distributed systems data integration is a main success factor in real-life business. Applying semantic web technologies for matching data is one successful approach for data integration. Ontoprise uses ontologies as target schema for integrating different sources like databases, text-_les and ontologies. However, the created target ontology and the corresponding mapping-rules might be error-prone. Hence, we developed the conflict resolution framework MappingAssistant which detects wrong rules or facts on the instance level in an interactive way. In this demo we present the MappingAssistant framework and an evaluation which emphasizes that users are used to investigate data on the instance level.
