Prepare the data
Use licensed review text with sentiment labels and remove duplicates before splitting.
Read the review. Check the sentiment label.
Movie-review sentiment classification uses labelled reviews to learn language associated with opinions. Negation, sarcasm, mixed opinions and duplicated reviews are important error cases.

Movie-review sentiment classification uses labelled reviews to learn language associated with opinions. Negation, sarcasm, mixed opinions and duplicated reviews are important error cases.
A possible application for film clubs: Help film-club organisers explore voluntary review feedback without treating a score as a definitive opinion. This extension is not delivered by the supplied starter.
Use licensed review text with sentiment labels and remove duplicates before splitting.
Fit a TF-IDF and logistic-regression baseline using only training text for vocabulary learning.
Measure macro F1 and inspect negation, sarcasm and mixed-sentiment examples separately.
Provide a review-summary panel with examples users can correct.
The supplied starter splits six hand-written sentences with binary labels, fits a TF-IDF unigram/bigram vectoriser and LogisticRegression pipeline, then prints a report and 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)
print(classification_report(y_test, predictions, zero_division=0))The supplied six sentences are not movie reviews and do not validate movie sentiment. A two-example test set cannot support useful performance claims. The sentences are not a representative corpus, and their binary labels do not establish the richer task described in the project title.
Proposed extension: Help film-club organisers explore voluntary review feedback without treating a score as a definitive opinion.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
