An integrated ontology development environment for data extraction
Stephen W. Liddle, Kimball A. Hewett, David W. Embley · 2003
Abstract: Data extraction is a necessary technology to deal with the huge and grow-ing collection of unstructured and semistructured information available on the World Wide Web. Ontology-based data extraction is a robust approach, but the construction of ontologies is a technical task requiring the services of a human expert. We present a Java-based tool for the graphical creation and testing of data extraction ontologies. This tool leverages standards such as Java and XML to provide a portable, extensi-ble, maintainable, feature-rich environment. This tool reduces the burden on expert ontology developers and simplifies the task of ontology creation. 1
