After defining the intents and entities of your chatbot, the next step is to train its NLP (Natural Language Processing) model. You can easily accomplish this by providing a dataset of labeled examples representing the various types of user inputs your chatbot will handle in the future. Once you have trained the model, it is time to test it using sample inputs and refine it to enhance its accuracy. By regularly fine-tuning the NLP model based on user interactions, the chatbot can learn and improve its ability to accurately understand and respond to user inputs.
