Assemble and clean data
Collect paired source–summary examples (news, reports or licences) and remove near-duplicates and truncation artefacts before splitting.
Train a seq2seq summariser. Inspect generated summaries.
Seq2Seq summarisation trains a conditional generation model to map long source texts to shorter summaries. Key issues include factual consistency, handling long inputs, evaluation with ROUGE/ROUGE-L and human checks, and preventing model hallucination on factual documents.

Seq2Seq summarisation trains a conditional generation model to map long source texts to shorter summaries. Key issues include factual consistency, handling long inputs, evaluation with ROUGE/ROUGE-L and human checks, and preventing model hallucination on factual documents.
A proposed application: help content teams produce concise first drafts of summaries that a human editor reviews and corrects. The supplied starter does not deliver generation or a seq2seq model; this is a suggested extension.
Collect paired source–summary examples (news, reports or licences) and remove near-duplicates and truncation artefacts before splitting.
Fine-tune a Transformer encoder–decoder (e.g. BART/T5) or train a small RNN seq2seq model with attention, controlling input length and using teacher forcing.
Report ROUGE scores, inspect factual consistency and common failure modes such as hallucination and missing entities using manual examples.
Expose summaries via an editor API, log outputs and human corrections, and add monitoring for drift and degraded factuality.
The supplied starter is a small text classification baseline: it vectorises six short sentences with TfidfVectorizer, fits a LogisticRegression classifier, prints a classification report on a 2–4 test split, and shows one sample prediction. It does not implement any seq2seq model, encoder–decoder architecture, or text generation.
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 trains a TF-IDF + LogisticRegression classifier on six labelled sentences; it contains no encoder–decoder, no generation step, and no paired source–summary dataset required for seq2seq summarisation.
Proposed extension: fine-tune a small pre-trained encoder–decoder model (e.g. BART/T5) on a curated paired dataset, add beam search and length penalties, and provide an editor interface for human review.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
