Key-Concept Extraction for Ontology Engineering

We present a framework for supporting ontology engineering by exploiting key-concept extraction. The framework is implemented in an existing wiki-based collaborative platform which has been extended with a component for terminology extraction from domain-specific textual corpora, and with a further step aimed at matching the extracted concepts with pre-existing structured and semi-structured information. Several ontology engineering related tasks can benefit from the availability of this system: ontology construction and extension, ontology terminological validation and ranking, and ontology concepts ranking.
