A Framework for Extraction Plans and Heuristics in an Ontology-Based Data-Extraction System A Framework for Extraction Plans and Heuristics in an Ontology-Based Data-Extraction System
Extraction of information from semi-structured or unstructured documents, such as Web pages, is a useful yet complex task. Research has demonstrated that ontologies may be used to achieve a high degree of accuracy in data extraction while maintaining resiliency in the face of document changes. Ontologies do not, however, diminish the complexity of a data-extraction system. As research in the field progresses, the need for a modular data-extraction system that de-couples the various functional processes involved continues to grow.
