5 Models for Conversational AI

How can chatbots become truly intelligent by combining five different models of conversation? Conversational AI is all about making machines communicate with us in natural language. They are called using various names -- chatbots, voice bots, virtual assistants, etc. In reality, they may be slightly different to each other. However one key feature that ties them all together is their ability to understand natural language commands and requests from us-human users. In the back-end, these agents will have to deal with carrying out the request and engage in a conversation.
