New framework evaluates semantic correctness of open-ended QA answers

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called CAP-Correctness to evaluate the semantic correctness of answers generated by open-ended question-answering systems. This framework addresses limitations in existing metrics by categorizing answers into eight ordered classes, distinguishing between complete and correct responses versus those containing inaccuracies like hallucinations or contradictions. The system also includes CAP-Statements for training natural language inference models and CAP, a reference-based metric that utilizes bidirectional NLI to score question-conditioned statements, outperforming established baselines in monotonicity tests.

IMPACT Improves evaluation of LLM-generated answers, enabling more reliable assessment of QA system capabilities.

    How Correct Is Your Answer? A Semantic Correctness Framework for Open QA Evaluation

    arXiv:2609.01369v1 Announce Type: new Abstract: Reliable evaluation of open-ended question answering remains a bottleneck for measuring answer correctness of modern LLMs. Unlike multiple-choice tasks, free-form answers may be correct in many surface forms and may fail in qualitat…
