Ontology-Based Mediation with Quality Criteria

Information integration has a long history since humans started using and collecting information. But, it been strong focus of IT research many recent years. It deals with providing unified transparent access to collection heterogeneous data sources. In information integration, the formulization global schema is difficult task that manages multiple, autonomous This paper presents semantic system named OntMed for an ontology-based sources achieve interoperability between them. Our based on quality criteria (consistency, completeness conciseness) building reliable analysis contexts provide accurate view end user. The generation error-free context validation initial mappings generates accuracy, provides means exchange in semantically sound manner. addition, this way becomes more practical dynamic situations helps decision makers work within consistent virtual warehouse.
