Collect and label examples
Assemble user queries that reflect real noise and annotate a clear intent taxonomy; include an 'other' label for out-of-scope queries.
Detect user intent with embeddings. Compare representations and errors.
Intent detection assigns a label describing a user's goal from short text. Good datasets include realistic queries, noisy phrasing, and multiple intent classes; common failure modes are out-of-vocabulary intents, overlapping labels and ambiguous short inputs.

A proposed application: an internal support routing assistant that suggests the most likely team for a user query; a human reviewer remains in the loop to confirm routing decisions and correct ambiguous cases.

Compare classical TF-IDF baselines with transformer embeddings (e.g. sentence-BERT) and freeze or fine-tune as needed.
Split by conversation/session if needed, measure per-class precision/recall and macro F1, and inspect confusion among similar intents.
Wrap the chosen model behind an API, add human-review paths for low-confidence predictions, and monitor drift in input phrasing.
The supplied starter trains a TF-IDF + LogisticRegression pipeline on six short, hand-written sentences with binary labels, prints a classification report on a small test split, and shows one sample prediction. It does not compute or use transformer embeddings.
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 TF-IDF and logistic regression rather than transformer-derived embeddings. The dataset is six contrived sentences with binary labels, so reported metrics are not meaningful for real intent detection and cannot demonstrate transformer behaviour or multi-intent classification.
A proposed extension: replace TF-IDF with a pre-trained sentence-transformer to embed examples, retrain a classifier on those embeddings, and evaluate on a larger labelled intent dataset with multiple classes.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
