Anatomy of Chatbots

Natural language conversation is one of the most challenging artificial intelligence problems, which involves language understanding, reasoning, and the utilization of common sense knowledge. Previous works in this direction mainly focus on either rule-based or learning-based methods. These types of methods often rely on manual effort in designing rules or automatic training of model with a particular learning algorithm and a small amount of data, which makes it difficult to develop an extensible open domain conversation system. Chatbots (also known as Conversation Agents or Dialog based Agents) make use of Natural Language conversation models. They are the latest trend.
