Summary

HalluCiteChecker is a new toolkit designed to detect and verify hallucinated citations in scientific papers, a growing problem exacerbated by AI assistant technologies that recommend citations. These non-existent citations compromise scientific credibility and increase the manual verification burden on reviewers and authors. The toolkit formalizes hallucinated citation detection as an NLP task, offering a practical solution. It is lightweight, capable of performing verification in seconds on a standard laptop using only CPUs, and operates entirely offline. Released under the Apache 2.0 license, HalluCiteChecker aims to reduce reviewer workload and support systematic pre-review and publication checks.

Key takeaway

For research scientists and journal reviewers tasked with ensuring academic integrity, HalluCiteChecker offers a critical tool to combat AI-generated citation hallucinations. Implementing this lightweight, offline, CPU-efficient package can significantly reduce the manual burden of verifying references, streamlining the review process and enhancing the credibility of scientific publications.
