Assemble realistic news data
Collect multi-class labelled news articles or use a public corpus; include headlines, body text and representative noise such as short summaries and syndicated duplicates.
01 / THE IDEA
News text classification in practice.
News categorisation assigns one or more topic labels to article text to support search, routing and analytics. Real problems include many classes, imbalanced labels, noisy headlines and near-duplicate copies; evaluation should report per-class precision and recall and inspect common confusions.
Real-world use case · Proposed extension
A proposed newsroom tagging tool: assist editors by pre‑suggesting topic labels and prioritising articles for review, with a human in the loop to correct uncertain or high‑impact predictions. This extension is not delivered by the supplied starter.
02 / THE BUILD
How to build a news categorisation project
step by step.
Build a baseline pipeline
Fit a TF‑IDF vectoriser and a multinomial or logistic classifier as a reproducible baseline, keeping preprocessing and tokenisation consistent between train and test.
Evaluate per-class performance
Report macro and per-class precision, recall and confusion matrices; inspect frequent error cases such as overlapping topics and short headlines.
Plan a reviewable deployment
Expose predictions with confidence scores and a correction UI so editors can review and correct labels, enabling continual retraining on corrected examples.
03 / SOURCE SNAPSHOT
What the news categorisation starter actually does.
The supplied starter defines six short, hand-written sentences with binary labels, splits them into train and test, fits a scikit-learn Pipeline that applies TfidfVectorizer and LogisticRegression, prints a classification report on the tiny test split and outputs one sample prediction.
SOURCE EXCERPTPython
model = Pipeline(
steps=[
("tfidf", TfidfVectorizer(ngram_range=(1, 2), min_df=1)),
("classifier", LogisticRegression(max_iter=1000)),
]
)
model.fit(X_train, y_train)Important limitation
The starter uses six generic sentences with binary labels rather than a multi-class news corpus and therefore does not implement news categorisation. It lacks multi-class labels, realistic article text, and news-specific preprocessing such as headline/body handling and deduplication.
04 / BEYOND THE CLASSROOM
Where a news categorisation project could go next.
PROPOSED BUSINESS CONCEPT
News categorisation: a pilot extension
Proposed extension: replace the toy examples with a labelled news dataset, expand to multiple topic labels, add headline/body concatenation, deduplication and a confidence threshold that routes uncertain articles to human editors.
WHO IT COULD SERVENewsrooms and editorial teams
FIRST MVPA reproducible pipeline that trains on a multi-class news dataset, serves predictions via a simple API and shows low‑confidence items in a review UI for editor correction.
KEY RISKMistagged or biased training data can surface incorrect topic labels; include human review for editorial decisions and avoid relying on the model alone for content moderation.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
05 / WHAT YOU TAKE AWAY
What a news categorisation project puts on your resume.
- Assemble and clean a multi-class news dataset and handle duplicates and short texts.
- Train a reproducible TF‑IDF and logistic baseline with consistent preprocessing.
- Evaluate using macro and per-class precision and recall and inspect common confusions.
- Design a review workflow that surfaces low‑confidence predictions for human correction.

06 / QUESTIONS STUDENTS ASK
News Categorisation project FAQs.
- Is this suitable as a final year project?
- Yes — news categorisation is a practical final year project that covers dataset handling, multi-class modelling and evaluation; expand the starter to a real multi-class news corpus and thorough analysis.
- What skills and tools will I need to learn?
- You should know Python, scikit-learn, NLP preprocessing (tokenisation, lemmatisation via spaCy), feature engineering like TF‑IDF, class imbalance handling and evaluation metrics.
- How should I evaluate progress and how long will it take?
- Measure per‑class precision/recall, macro F1 and confusion matrices; expect 6–12 weeks to collect/clean data, implement models and run experiments depending on scope and dataset size.
