We present a novel system for corpus-based terminological evaluation of ontologies. Starting from the assumption that a domain of interest can be represented through a corpus of text documents, we first extract a list of domain-specific key-concepts from the corpus, rank them by relevance, and then apply various evaluation metrics to assess the terminological coverage of a domain ontology with respect to the list of key-concepts.Among the advantages of the proposed approach, we remark that the framework is highly automatizable, requiring little human intervention. The evaluation framework is made available online through a collaborative wiki-based system, which can be accessed by different users, from domain experts to knowledge engineers.We performed a comprehensive experimental analysis of our approach, showing that the proposed ontology metrics allow for assessing the terminological coverage of an ontology with respect to a given domain, and that our framework can be effectively applied to many evaluation-related scenarios.
