The rise of DeepFake technology in the digital era presents both opportunities and challenges, significantly impacting misinformation through realistic fake content creation, especially in social media tweets [18, 15]. The proliferation of DeepFakes poses a substantial threat to the integrity of information on social media platforms, where the rapid dissemination of false content can lead to widespread misinformation and public distrust. Addressing this issue is critical for maintaining the reliability of digital communications and ensuring that users can distinguish between authentic and manipulated content. Our study leverages natural language processing (NLP) to develop a DeepFake tweet detection framework, aiming to bolster social media information reliability and pave the way for further research in ensuring digital authenticity. By focusing on the linguistic and contextual nuances that differentiate genuine tweets from AI-generated ones, we seek to create a robust detection mechanism that can be integrated into existing social media platforms to mitigate the spread of misinformation. Focusing on detecting DeepFake content in tweets, this research employs the TweepFake dataset to evaluate various text representation and preprocessing methods. The TweepFake dataset provides a diverse and comprehensive collection of tweets that facilitate the training and testing of different detection models. We explore effective embeddings and model-This work was funded by the European Union under the Horizon Europe grant OMINO (grant no 101086321) and by the Polish Ministry of Education and Science within the framework of the program titled International Projects Co-Financed.
