It takes one to know one-Machine learning for identifying OBGYN abstracts written by ChatGPT

To use machine learning to optimize the detection of obstetrics and gynecology (OBGYN) Chat Generative Pre-trained Transformer (ChatGPT) -written abstracts of all OBGYN journals.

We used Web of Science to identify all original articles published in all OBGYN journals in 2022. Seventy-five original articles were randomly selected. For each, we prompted ChatGPT to write an abstract based on the title and results of the original abstracts. Each abstract was tested by Grammarly software and reports were inserted into a database. Machine-learning modes were trained and examined on the database created.

Overall, 75 abstracts from 12 different OBGYN journals were randomly selected. There were seven (58%) Q1 journals, one (8%) Q2 journal, two (17%) Q3 journals, and two (17%) Q4 journals. Use of mixed dialects of English, absence of comma-misuse, absence of incorrect verb forms, and improper formatting were important prediction variables of ChatGPT-written abstracts. The deep-learning model had the highest predictive performance of all examined models. This model achieved the following performance: accuracy 0.90, precision 0.92, recall 0.85, area under the curve 0.95.
