Abstract This study investigates the effectiveness of various text representation methods in distinguishing between AI-generated and human-written content, using a corpus of 1000 Italian essays. Four techniques were employed for text representation: Text Features, Most Frequent Words (MFWs), Correspondence Analysis (CA), and a fine-tuned Large Language Model (LLM). Machine learning models, including Random Forests, Elastic-net, and Support Vector Machine, were applied to these representations.
