Hybrid chatbot
A conversational system that combines generative language models with intent routing, rules, templates, search, or other conventional techniques.
Natural Language Processing in Action, Second Edition
A hybrid chatbot combines generative language models with rules, templates, or other conventional conversational techniques.
- How it is used
- Uses hybrid chatbots to balance responsive educational conversation against misleading or harmful LLM replies.
- How deep it goes
- Works through a LangChain conversational prototype and its failures, but does not implement the proposed RAG or rule-based filters.
- Examples
- Uses a WhatsApp math tutor’s parent-permission dialogue and a number-sequence quiz that produces contradictory feedback.
- What you can do after
- Apply it via LangChain to prototype a conversational tutor and identify replies that need grounding or independent checks.

Effective Conversational AI
A hybrid model combines intent-based routing with search or generative-AI capabilities in one conversational system.
- How it is used
- Routes common questions through intents and sends other questions to search or generative AI.
- How deep it goes
- Defines the routing pattern and contrasts alternatives, but gives no design or implementation steps.
- Examples
- Contrasts FAQ intent-response matching with search-backed generated answers; provides no specific hybrid dialogue.
- What you can do after
- Evaluate chatbots by classifying their patterns and identifying performance challenges.
