The Rise of AI-Generated Research Papers
ArXiv, a widely used open repository for preprint research, is taking steps to crack down on the careless use of large language models in scientific papers. Although papers are posted to the site before they are peer-reviewed, ArXiv has become one of the main ways that research circulates in fields like computer science and math.
ArXiv's New Policy
The organization has already taken steps to combat a growing number of low-quality, AI-generated papers, such as requiring first-time posters to get an endorsement from an established author. In its latest move, ArXiv will ban authors for a year if they submit papers that contain "incontrovertible evidence" that the authors did not check the results of LLM generation.
The Data Analysis
Authors who submit AI-generated papers without proper oversight will face a 1-year ban from ArXiv.
After the ban, authors will be required to have subsequent ArXiv submissions accepted by a reputable peer-reviewed venue.
The Impact Analysis
Recent peer-reviewed research has found that fabricated citations are on the rise in biomedical research, likely due to LLMs. ArXiv's new policy aims to ensure that authors take "full responsibility" for the content, "irrespective of how the contents are generated."
The Prediction
The move is expected to have a significant impact on the scientific community, as researchers will need to be more transparent about their use of AI-generated content. ArXiv's new policy is a "one-strike" rule, but moderators must flag the issue and section chairs must confirm the evidence before imposing the penalty. Authors will also be able to appeal the decision.
