Prepare an author-labelled corpus
Collect multiple texts per author, ensure enough samples per author, and balance or record class-imbalance for evaluation.
Identify an author from text. Check attribution reliability.
Author identification (authorship attribution) maps text samples to their likely author using stylistic, lexical and syntactic features. Important failure modes include short texts, topical confounds (topic vs author), cross-domain writing, and deliberate obfuscation.

Author identification (authorship attribution) maps text samples to their likely author using stylistic, lexical and syntactic features. Important failure modes include short texts, topical confounds (topic vs author), cross-domain writing, and deliberate obfuscation.
Proposed application for publishers or editors: flag likely author mismatches in anonymised or multi-author drafts so a human reviewer can inspect and confirm. This extension is not provided by the supplied starter.
Collect multiple texts per author, ensure enough samples per author, and balance or record class-imbalance for evaluation.
Use TF-IDF n‑grams, character n‑grams and function-word frequencies or transformer embeddings to capture author style beyond topic words.
Fit a multi-class classifier with cross-validation grouped by document to avoid leakage, and report macro F1 and confusion matrices across authors.
Provide top-k author candidates, example supporting phrases, and allow a reviewer to correct labels and mark uncertain cases.
The supplied starter defines six hand-written sentences with binary labels, splits them into train and test, fits a TF-IDF (unigram+bigram) + LogisticRegression pipeline, prints a classification report on the tiny test split and shows one sample prediction. It does not use an author-labelled corpus or multi-author labels.
model = Pipeline(
steps=[
("tfidf", TfidfVectorizer(ngram_range=(1, 2), min_df=1)),
("classifier", LogisticRegression(max_iter=1000)),
]
)
model.fit(X_train, y_train)The code uses six generic sentences with binary labels and therefore contains no author identities or multi-author data; it cannot validate author identification or assess per-author performance.
Proposed extension: gather a small multi-author corpus (several authors, many samples per author), extract stylistic features, and train a multi-class author classifier that shows top candidates and supporting text snippets 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.
