Abstract: Misinformation detection is a crucial task in today’s digital age, aiming to identify whether a news article is true or fabricated. An AI-powered application is developed that utilizes advanced Large Language Models (LLMs), Transformer-Based Pretrained Language Models namely BERT and LLaMA named as LAMBERT model, to classify news content as true or fabricated. The system is trained using a dataset obtained from Kaggle, which comprises approximately 21,417 true news articles and 23,502 fake ones. The primary focus is on detection of fabricated news on political news dataset, as this domain is particularly vulnerable to the spread of misinformation. By fine-tuning the models on this specific dataset, the model performance is improved because of the usage of BERT and LLaMA which enhances the capability of the system to record nuanced contextual and semantic features inherent in natural language. BERT’s bidirectional transformer architecture is adept at understanding the context from both preceding and succeeding words, which is vital in discerning subtle linguistic cues often present in fabricated news. Meanwhile, LLaMA contributes by efficiently processing huge amount of text data and learning complex patterns that are characteristic of political misinformation. Together, these models provide a robust framework for distinguishing between true and false news, thereby mitigating the spread of false news effectively.
