Fake News Detection — Misinformation Classification
Fake News Detection (Misinformation Classification) · Also known as: misinformation detection, false news classification, automated fact checking, Yanlış/Sahte Haber Tespiti
Fake news detection is a natural-language-processing classification task that assesses the credibility of news text and labels content as fake or genuine. Building on the social-media framing of Shu et al. (2017) and the automated-fact-checking framing of Thorne and Vlachos (2018), it turns unstructured news articles into a supervised credibility decision learned from labelled examples.

When to use it
Use fake news detection when you have news text to classify and a labelled training set marking articles as fake or real. The method needs a reasonable amount of data — around 100 documents or more — and benefits when source and context information is available. Without labelled examples it cannot be trained, and without any text data it cannot run at all.
Strengths & limitations
- Turns the manual, slow task of credibility judgement into a repeatable supervised classification.
- Scales from a fast TF-IDF linear classifier to a context-aware BERT-based model without changing the overall pipeline.
- Improves when source and context signals are added alongside the article text.
- Requires a labelled training set; with no labelled examples the model cannot be trained.
- Needs a reasonable amount of data — roughly 100 documents or more — to learn reliable patterns.
- Model quality depends heavily on whether source and context information is available and on how well the training labels reflect reality.
Frequently asked
TF-IDF classifier or BERT — which should I use?
A TF-IDF linear classifier is fast and works well as a strong baseline on moderate corpora. A BERT-based model captures context beyond individual keywords and is preferred when more semantic understanding is needed, at higher computational cost. Start simple and move to BERT if the baseline underperforms.
How much data do I need?
You need a labelled training set marking articles as fake or real, with around 100 documents or more. Too few examples leave the classifier without enough signal to generalise reliably.
Does the source of an article matter?
Yes. When source and context information is available alongside the text, model quality improves, because credibility is not carried by wording alone. Keep this information through preprocessing wherever you can.
How do I know the model is trustworthy?
Evaluate it on held-out labelled data with accuracy, F1, precision, and recall, and inspect misclassifications. On imbalanced labels, accuracy alone is misleading, so rely on the per-class scores, and revalidate before applying the model to a new outlet, topic, or time period.
