Ontology construction usually requires a domain-specific corpus for building corresponding concept hierarchy. The domain corpus must have a good coverage of domain knowledge. Wikipedia(Wiki), the world's largest online encyclopaedic knowledge source, is open-content, collaboratively edited, and free of charge.
