【摘要】 在构成常识性推理的３ 个基本部分中，不确定性推理（假设评价）是最重要的．论述了几种常用的定量不确定性推理方法，即基于概率论的推理方法、证据理论、模糊逻辑和信息推理等，以及建立在这些不确定性推理方法上的包含度理论，并论述了包含度理论和不确定性推理技术在知识获取中的应用更多还原

【Abstract】 In the three parts of common sense reasoning, uncertain reasoning is most important. Several method of familiar quantificational uncertain reasoning, such as reasoning based probability, evidence theory, fuzzy reasoning, information reasoning, and inclusion degree theory based on uncertain reasoning is introduced. The use of inclusion degree theory and uncertain reasoning in knowledge acquisition is also discssed.更多还原
