It often takes hours to make the bib file very clean and consistent. For example, we often have to check if each arXiv paper has been accepted to a conference or journal. The conference names are messed up and not consistent: NeurIPS vs NIPS vs Neural Information Processing Systems vs Neural Information Processing Systems (NeurIPS). The title of the paper is not capitalized properly, e.g., "llm"/"ai" instead of "LLM"/"AI". Some authors may be missing. The list goes on.
With LLMs and recent web search tools, this tedious work no longer needs to be manual. Bibfixer will do this for us: it completes entries with accurate metadata via LLM + web search capabilities, but also enforces a consistent style based on your preferences. Of course, we should check the final output since LLMs can also make mistakes, but this is much easier than doing this fully manually.
