How can I improve entity recognition accuracy in my Rasa chatbot?
Asked on Nov 30, 2025
Answer
Improving entity recognition accuracy in a Rasa chatbot involves refining your training data and leveraging Rasa's configuration options. This can be achieved by enhancing your NLU model with more diverse examples and adjusting pipeline components.
Example Concept: To improve entity recognition in Rasa, ensure your training data includes varied examples of each entity type. Use the "RegexFeaturizer" and "CRFEntityExtractor" in your NLU pipeline to enhance recognition. Additionally, consider using the "LookupTable" feature for entities with a fixed set of possible values, which helps the model recognize entities more accurately.
Additional Comment:
- Review and expand your training data to cover different contexts and variations of entity usage.
- Use Rasa's interactive learning to refine entity extraction through real-time feedback.
- Test and iterate on your NLU model by evaluating its performance with unseen data.
- Consider using pre-trained embeddings like "SpacyNLP" for better language understanding.
