Evaluating factuality on long, complex model outputs
Avoid evaluating factuality by checking many claims within long, generated text.
Focus on short, fact-seeking questions with single, verifiable answers to make evaluation more tractable and reliable.
Attempting to measure language model factuality by evaluating all factual claims within long, generated responses.
Long outputs contain numerous claims, making comprehensive and accurate fact-checking difficult and time-consuming. This complexity increases the chance of errors in the evaluation itself.
Evaluating factuality by scrutinizing every claim in a long model output is impractical. Instead, use short, specific questions with clear, verifiable answers for more reliable assessment.
Short, fact-seeking questions isolate specific pieces of information, making them easier to verify. This focused approach reduces the complexity and potential for error in the evaluation process.
When the specific task requires the model to generate and support complex arguments or narratives.
