An Ergonomics Evaluation to Chatbot Equipped with Knowledge-Rich Mind

Nowadays, more and more chatbots can get acquainted with the world by equipping with knowledge-rich minds which connect to Internet. In this paper, we will first explore how to integrate more knowledge into chatbot and how to make chatbot be aware of what are going on in the world. On top of that, a series of evaluations were performed on the prototype system. Through the evaluations, we mainly want to validate the proposed method in the prototype system and how the abundant level of knowledge accumulation of a chatbot affects the interactions between the chatbot and the users from the user satisfaction aspect. Experiment shows that the proposed method not only broadens the knowledge boundary of chatbot, but also makes the talks between users and chatbot more coherent. In addition, it shows that the level of user satisfaction is proportional to the amount of fact knowledge.
