知识云及其在知识获取中的意义

Knowledge acquisition is one of the key problems in artificial intelligence(AI), and it has been attacked from a number of perspectives.This paper introduces a fresh standpoint for knowledge acquisition.The standpoint consists of the belief that,around the knowledge kernel of an expert,there are layers of knowledge clouds,and these clouds are the entry to the recognition of the knowledge kernel of the expert.Based upon this belief,the paper discusses what knowledge clouds are and what roles they play in knowledge acquisition.
