Ontology Evaluation Checklist

Computational ontologies are key to information retrieval, semantic integration of datasets, and semantic similarity analyses. It's sometimes a challenge to find a self-contained material where you can find "what" to evaluate after you've designed an ontology (criteria), and "how" to do it (strategies). Here you may find a start. Depending on the use case, and the intended audience, it may be interesting to evaluate design aspects, or implementation aspects, or both.

Design: support human reasoning


  • Accuracy (correct representation of aspects of the real world)

  • Adaptability (ease of performing changes)

  • Clarity (effective communication of the intended meaning of defined terms)

  • Cognitive adequacy (match between formal and cognitive semantics)

  • Completeness (appropriate coverage of the domain of interest)

  • Conciseness (absence of unnecessary or useless definitions or axioms)

  • Consistency (incapacity of getting contradictory conclusions from valid input data)

  • Expressiveness (number of competency questions that the ontology can answer)

  • Grounding (number of assumptions done by the ontology’s underlying philosophical theory about reality)

Implementation: support automated reasoning


  • Computational efficiency (ease and speed of processing by reasoners)

  • Congruency (fitness between ontology and corpus terms)

  • Practical usefulness (number of practical problems to which the ontology can be applied)

  • Precision (fraction of retrieved instances by the ontology that are relevant)

  • Recall (fraction of relevant instances that are retrieved by the ontology)


The list will be extended with strategies as I become aware of them. Reference: Degbelo, A. (2017). A snapshot of ontology evaluation criteria and strategies. In R. Hoestra, C. Faron-Zucker, T.
