Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use Notion AI 3.0 to a validated, documented taxonomy of intents with clear definitions and example queries. Then, you pass the output to LightTag to a labeled, balanced dataset ready for model training, with clear train/val/test splits. Then, you pass the output to scikit-learn to a trained classification model with documented performance metrics on the validation set. Then, you pass the output to scikit-learn to a validated model with known performance on unseen data and a calibrated confidence threshold. Then, you pass the output to Azure AI to a live api endpoint that accepts text and returns intent classification in real-time. Finally, Microsoft LUIS (Language Understanding) is used to a production system with monitoring, feedback collection, and automated retraining for sustained accuracy.
Define and Scope Intent Taxonomy
A validated, documented taxonomy of intents with clear definitions and example queries.
Prepare and Annotate Training Data
A labeled, balanced dataset ready for model training, with clear train/val/test splits.
Select and Train a Classification Model
A trained classification model with documented performance metrics on the validation set.
Test and Calibrate on Unseen Data
A validated model with known performance on unseen data and a calibrated confidence threshold.
Deploy as an API or Service
A live API endpoint that accepts text and returns intent classification in real-time.
Monitor and Continuously Improve
A production system with monitoring, feedback collection, and automated retraining for sustained accuracy.
Start by gathering business requirements and analyzing sample user queries to identify distinct intents. Create a hierarchical taxonomy with clear definitions, examples, and edge cases for each intent. Validate with stakeholders to ensure coverage and avoid ambiguity.
Why Notion AI 3.0: Notion AI 3.0 combines a documentation tool with AI agents that can help define and organize an intent taxonomy, plus it supports spreadsheets and cross-app search.
Collect a dataset of user utterances and manually label each with the correct intent from your taxonomy. Ensure balanced representation across intents and include edge cases. Split data into training, validation, and test sets (e.g., 70/15/15).
Why LightTag: LightTag is a dedicated annotation platform for text classification, making it ideal for labeling training data for intent classification.
Choose a baseline model (e.g., logistic regression with TF-IDF) and a deep learning model (e.g., BERT or DistilBERT) for comparison. Train on the annotated dataset, tuning hyperparameters to maximize accuracy and F1-score. Evaluate on the validation set to avoid overfitting.
Why scikit-learn: scikit-learn provides classification algorithms directly needed for training a model, and is a core library in the step's requirements.
Run the trained model on the held-out test set to measure generalization. Analyze confusion matrix to identify common misclassifications. Calibrate confidence thresholds or add rejection rules for low-confidence predictions.
Why scikit-learn: scikit-learn provides the metrics (e.g., accuracy, F1-score) needed to test and calibrate the model on unseen data.
Package the trained model into a lightweight inference service (e.g., FastAPI or Flask) with a REST endpoint. Add input validation, logging, and monitoring for latency and accuracy. Deploy to a cloud server or containerized environment.
Why Azure AI: Azure AI provides model deployment and agent orchestration, fitting the need for deploying an intent classification API or service.
Set up dashboards to track model performance in production, including drift detection and user feedback loops. Periodically retrain the model with new labeled data to adapt to changing user language or new intents.
Why Microsoft LUIS (Language Understanding): Microsoft LUIS includes active learning, which is essential for continuously improving the model based on new data and feedback.
§ Before you start
Teams or solo builders working on work tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
