This paper presents CheckList, a behavioral testing methodology that systematically evaluates Natural Language Processing models using a matrix of linguistic capabilities and test types. Applying CheckList revealed widespread and severe failures in both commercial APIs and state-of-the-art research models across fundamental capabilities, despite high benchmark accuracy.

Key insights

  • High accuracy on traditional benchmarks does not guarantee robust linguistic understanding or real-world reliability in NLP models.
  • Applying software engineering principles like behavioral testing and systematic test generation can effectively identify specific model weaknesses.
  • A structured matrix of linguistic capabilities and test types (Minimum Functionality, Invariance, Directional Expectation) enables comprehensive and diagnostic evaluation.
