Ontology Driven Data Integration in Heterogeneous Networks

We propose a layered framework for the integration of syntactically, schematically, and semantically heterogeneous networked data sources. Their heterogeneity stems from different models (e.g., relational, XML, or RDF), different schemas within the same model, and different terms associated with the same meaning. We use a semantic based approach that uses a global ontology to mediate among the ...

Ontology-based heterogeneous XML data integration

In this paper we present an ontology-based method for formalizing the implicit semantic and we suggest mechanisms to semantically integrate XML schemas and documents as well. After a survey of database interoperability, we present our semantic integration approach by explaining the nature of ontology. The article then presents our integration method for XML data and schemas using a generic onto...

An Ontology-Based Framework for Heterogeneous Data Sources Integration

1 The Proposed Framework Ontologies have been extensively used to model domain-specific knowledge. The main reason for this success is due to their capability to be at the " semantic " level, away from data structures and implementation strategies. In addition, ontology formalisms have allowed certain kinds of reasoning to be automated within a reasonable time complexity. Due to ontology data i...

Ontology-based information extraction and integration from heterogeneous data sources

In this paper we present the design, implementation and evaluation of SOBA, a system for ontology-based information extraction from heterogeneous data resources, including plain text, tables and image captions. SOBA is capable of processing structured information, text and image captions to extract information and integrate it into a coherent knowledge base. To establish coherence, SOBA interli...

Ontology-based Data Integration Ontology-based Data Integration

Nowadays, different areas of large modern enterprises use different database management systems to store and search their critical data. Competition, evolving technology, geographical distribution, and the inevitable growing decentralization contribute to this diversity. All of these databases are very important to an enterprise, but the their different interfaces make their administration diff...
