Can Deep Learning Detect Fake News Better when Adding Context Features?
Bibliographic record
Abstract
Fake news is increasing on social media and has huge negative impacts on society. To detect fake news, different approaches and algorithms have been studied. Recently, the use of deep learning algorithms has performed very well for fake news detection. Many researchers found the importance to add the context features to have better and a rapid detection. The current paper presents two algorithms, BERT and LSTM, for the classification of fake news, by using text and context features. Moreover, we add XAI solution that determines which context features have contributed the most to the classification of fake news. We have trained our model with an extraction of 5,000 news from the COVID-19 dataset. Our result shows that BERT performs better by 2.37% than LSTM by analyzing only the content and performs better by 2.24% by analyzing both, the content and the context. Finally, SHAP is used to explain fake news by highlighting the most relevant attributes that have helped to the classification of news.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
