Abstract: | The rapid expansion of information on the internet[1][2][3] has facilitated the spread of fake news, posing critical risks to public trust, institutional perception, and social stability. This project focused on analyzing various Natural Language Processing (NLP) techniques to develop a reliable model capable of detecting patterns associated with misinformation. Methods such as TF-IDF, Bag of Words (BoW), Word2Vec, and the transformer-based model DistilBERT were evaluated alongside classifiers like Logistic Regression, Support Vector Machines, and Random Forest. Advanced techniques, including dimensionality reduction with PCA and crossvalidation, were implemented to enhance model efficiency and robustness. However, results demonstrated that training a model solely with the text of news articles is insufficient for reliable predictions. Capturing the broader context—such as comments, sentiment analysis, sources, and related articles —is essential. This highlights the complexity of achieving accurate results, even with state-of-the-art text analysis models. This work contributes to the field by critically comparing various NLP techniques and classifiers, offering insights into their viability for detecting fake news in real-world contexts. |
