Abstract
When we humans converse with a person, we greet at first.Also in computers or robots, the next subject comes after greeting, and so they communicate with a person smoothly.So far the greeting process was only to apply the template, and its research has not been done so much.However, there is a problem that the responses are uniform by only using a prepared template, and only the sentences made by designer appear.Especially it is often that only the greeting sentences made by designer appear in the conversation.Then, the greeting processing system of this paper produces new greeting sentences.These sentences do not exist in the greeting knowledge base that the designer prepared either.For talking, we humans have general knowledge and common sense of words.In the same way, we use in the greeting process, the association knowledge mechanism that has general knowledge and common sense for computer.The method we proposed in this paper is to expand and refine sentences by combining the association knowledge mechanism with the greeting knowledge base.
