Chatbots is hot (and hard). In this talk, I will summarize our recent efforts in leveraging deep learning techniques to facilitate easy data access and build user friendly chatbots. The evolution and the connection among information retrieval, natural language interfaces to databases, task oriented and open domain conversational agents will be introduced. I will then discuss key issues in advancing conversational techniques including state awareness, knowledge grounding and fact checking. Solving these issues could lead us to general conversational agents in the future.
