Improving Detection of ChatGPT-Generated Fake Science Using Real Publication Text: Introducing xFakeBibs a Supervised-Learning Network Algorithm

ChatGPT is becoming a new reality. In this paper, we show how to distinguish ChatGPT-generated publications from counterparts produced by scientists. Using a newly designed supervised Machine Learning algorithm, we demonstrate how to detect machine-generated publications from those produced by scientists. The algorithm was trained using 100 real publication abstracts, followed by a 10-fold calibration approach to establish a lower-upper bound range of acceptance. In the comparison with ChatGPT content, it was evident that ChatGPT contributed merely 23\% of the bigram content, which is less than 50\% of any of the other 10 calibrating folds. This analysis highlights a significant disparity in technical terms where ChatGPT fell short of matching real science. When categorizing the individual articles, the xFakeBibs algorithm accurately identified 98 out of 100 publications as fake, with 2 articles incorrectly classified as real publications. Though this work introduced an algorithmic approach that detected the ChatGPT-generated fake science with a high degree of accuracy, it remains challenging to detect all fake records. This work is indeed a step in the right direction to counter fake science and misinformation.
