A Study on XML and Ontology-based Web Data Integration

Abstract

With the rapid development of Internet technology, web information system has achieved great development, and XML, as the new carrier and standard of information exchanging and calculating on the internet, has been widely used as well. While providing a uniform syntax and semi-structured data model, XML does not express semantics but only structure. This paper combines the web data integration problem and a XML and ontology-based data integration framework, including three main layers: distributed heterogeneous data sources layer, intermediary layer and application layer. Ontology is introduced as a tool in this framework. The experiment results verify the effectiveness of the proposed integration framework.
