FELM: Enhancing Factuality Evaluation in Large Language Models

## Assessing the Factuality of Large Language Models (LLMs)

Large language models (LLMs) have revolutionized generative AI through prompting. However, a major issue with LLMs is their tendency to generate incorrect information or hallucinate content, which limits their practical use. Even advanced LLMs like ChatGPT are not immune to this problem.

To address this challenge, researchers have focused on evaluating the factuality of text generated by LLMs. This area of research aims to improve the reliability of LLM outputs and inform users about potential errors. However, there is a lack of suitable evaluation tools for factuality assessors to measure progress and drive advancements in the field.

To fill this gap, the authors of this study introduce a benchmark called Factuality Evaluation of Large Language Models (FELM). FELM collects responses generated by LLMs and annotates factuality labels in a fine-grained manner. The benchmark covers factuality assessment across diverse domains, ranging from general knowledge to mathematical and reasoning-related content.

Through their tests, the researchers examine how well different computer programs, including those enhanced with extra tools, can identify factual errors in the text. The findings reveal that while retrieval mechanisms can aid in factuality evaluation, current LLMs still struggle to accurately detect factual errors.

The FELM benchmark not only advances our understanding of factuality assessment but also provides valuable insights into the effectiveness of different computational methods in identifying factual errors. This research contributes to ongoing efforts to enhance the reliability of language models and their applications.
