What is answer correctness?
Answer correctness: A measure of how close a generated answer is to a trusted reference answer, combining factual overlap and sometimes semantic similarity. It needs labelled ground truth, unlike faithfulness, which needs only the context.
Answer correctness: an example
The reference says 'Rs 500' and the answer says 'Rs 500', so correctness is high.
