6 Enhancing responses with retrieval-augmented generation

This chapter covers

Enhancing chatbot responses without coding intents
Improving weak understanding with RAG
Evaluating the advantage of using RAG over traditional search models
Selecting the proper RAG techniques for your conversational AI
Assessing and improving the performance of RAG in your conversational AI systems

In previous chapters, we saw the “chatbot doesn’t understand” pain point for question-answering bots. We first addressed it by helping the chatbot understand more intents, but at some point there are diminishing returns to this strategy. Uncommon questions from the “long tail” may never make sense to implement as intents. This chapter introduces ways to handle that ...
