Abstract
Systems and methods for detecting artificial intelligence (AI) generated text. A candidate text can be truncated to obtain a prefix text and a remainder text by employing a truncation module. Regenerated model texts can be regenerated by utilizing the prefix text by employing an AI text generation model. Detection results can be predicted by comparing n-gram similarities of the regenerated model texts and the remainder text. The candidate text can be distinguished as AI generated text by providing explanation texts based on the detection results.
Claims20
A computer-implemented method for detecting artificial intelligence (AI) generated text, by employing a processor device, comprising:
- truncating a candidate text to obtain a prefix text and a remainder text by employing a truncation module;
- obtaining regenerated model texts by utilizing the prefix text by employing an AI text generation model;
- predicting detection results by comparing n-gram similarities of the regenerated model texts and the remainder text;
- and
- distinguishing whether the candidate text is AI generated by providing explanation texts based on the detection results.
A system for detecting artificial intelligence (AI) generated text, comprising:
- a memory;
- and
- one or more processors in communication with the memory configured to:
- truncate a candidate text to obtain a prefix text and a remainder text by employing a truncation module;
- obtaining regenerated model texts by utilizing the prefix text by employing an AI text generation model;
- predict detection results by comparing n-gram similarities of the regenerated model texts and the remainder text by employing a detection module;
- and
- distinguish whether the candidate text is AI generated by providing explanation texts based on the detection results.
A non-transitory computer program product comprising a computer-readable storage medium including program code for detecting artificial intelligence (AI) generated text wherein the program code when executed on a computer causes the computer to perform:
- truncating a candidate text to obtain a prefix text and a remainder text by employing a truncation module;
- obtaining regenerated model texts by utilizing the prefix text by employing an AI text generation model;
- predicting detection results by comparing n-gram similarities of the regenerated model texts and the remainder text;
- and
- distinguishing whether the candidate text is AI generated by providing explanation texts based on the detection results.
