Intent Classification
A foundational task in natural language processing that determines the predefined category of a user input. It is commonly used in customer support scenarios, with accuracy or macro-averaged F1 as evaluation metrics.
Timeline (last 90 days)
Intent Classification is a fundamental task in natural language processing, referring to determining the semantic category of user input, and often serves as the first gate before query generation in Text-to-SQL scenarios.
In the design of price-type intent classification, recall matters more than precision: it is better to misclassify a non-price question as a price question and escalate it to a human than to miss a quote request.
The system first performs intent classification on user messages using a hybrid approach of rules plus a small model; when a price-type intent is hit (such as querying the gold rate, making charges, quotes, exchange value, or discounts), it does not enter the generation stage and is escalated directly to a human salesperson.
The evaluation metric for intent classification is usually accuracy or macro-averaged F1, because class distributions are often imbalanced.
Intent classification ranks alongside sentiment analysis and named entity recognition as one of the most common downstream applications of LLMs.
Quantization typically brings a 1%–3% accuracy loss, but for discriminative tasks with a limited label space such as intent classification it is almost imperceptible.
