- Caption Accuracy (Captioning Accuracy, Transcription Accuracy)
- A measure of how correctly captions represent the spoken content, typically expressed as the percentage of words that match the ground truth transcript. Caption accuracy is critical for deaf and hard …
- Controlled Language (CL, Controlled Natural Language)
- A restricted subset of a natural language that limits vocabulary, grammar, and style to reduce ambiguity and improve clarity and consistency in writing. In accessibility, controlled language rules can…
- Correctness (Precision, Validity)
- In the context of accessibility evaluation, correctness (also called precision) is the proportion of reported accessibility problems that are true problems — that is, issues that genuinely affect user…
- Evaluation Reliability (Inter-rater Reliability, Evaluator Agreement)
- The extent to which independent accessibility evaluations of the same content produce consistent results. High reliability means that different evaluators using the same method will identify similar s…
- F-measure (F-score, F1 Score)
- A metric that combines correctness (precision) and sensitivity (recall) into a single balanced score, calculated as the harmonic mean of the two values. In accessibility evaluation research, the F-mea…
- Hallucination (AI Hallucination, Confabulation)
- In the context of AI and large language models, the generation of content that is plausible-sounding but not grounded in the input data or factual reality. Hallucinations pose a particular risk in acc…
- Sampling Method (Sampling, Page Sampling, Site Sampling)
- A sampling method is a rule for selecting a subset of pages, screens, or components from a larger product to be evaluated for accessibility. Because full manual evaluation of every page on a real-worl…
- Sensitivity (Recall, Thoroughness, Completeness)
