Assemble representative data
Collect labelled news items from fact-checking organisations and include diverse sources, dates and writing styles; reserve a held-out set for final evaluation.
Detect fake news. Inspect precision and errors.
Fake-news detection is a text classification task that seeks to flag news items or claims that are likely false, misleading, or unverifiable. Important issues include dataset quality and label ambiguity, topical drift, adversarial wording, and the social impact of false positives. Human-in-the-loop review and clear provenance are essential.

Fake-news detection is a text classification task that seeks to flag news items or claims that are likely false, misleading, or unverifiable. Important issues include dataset quality and label ambiguity, topical drift, adversarial wording, and the social impact of false positives. Human-in-the-loop review and clear provenance are essential.
A proposed application is a newsroom support tool that flags potentially misleading articles for human fact-checkers to inspect; the supplied starter does not deliver a deployable or production-safe detector and requires further data, calibration and review controls.
Collect labelled news items from fact-checking organisations and include diverse sources, dates and writing styles; reserve a held-out set for final evaluation.
Train a TF-IDF plus logistic-regression pipeline or a lightweight transformer embedding model and track versions and hyperparameters.
Report precision, recall and macro F1, inspect false positives on sensitive topics and measure performance by topic and time slices.
Deliver model scores with provenance and example evidence, and let human fact-checkers triage and correct predictions.
The supplied starter fits a scikit-learn Pipeline with a TfidfVectorizer and LogisticRegression on six hand-written sentences with binary labels, prints a classification report on a small test split, and shows one sample prediction.
model = Pipeline(
steps=[
("tfidf", TfidfVectorizer(ngram_range=(1, 2), min_df=1)),
("classifier", LogisticRegression(max_iter=1000)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)The code uses six generic sentences rather than news articles and its labels are arbitrary; it therefore does not train or validate a real fake-news detector and cannot support meaningful performance claims.
Proposed extension: replace the toy texts with a curated fact-checked dataset, add a more robust representation (transformer embeddings), and expose model scores plus provenance to a human-review dashboard.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
