知效用的测度方法研究

针对知识效用的定量测度问题,提出以知识解决的问题量来计算知识效用,使用选择权值、状态转移概率、模糊隶属度直接计算问题量,获得了与信息熵计算相似的知识效用测度公式。数值计算结果与人们使用知识的印象一致。如果一个知识解决多个问题,其效用数量不变,符合知识的共享性和可重用性,可用于教育、情报、管理和经济等领域定量评价核心知识或原始知识创新。

Method of measuring knowledge performance

To compute knowledge performance,a new method based on the amounts of problem resolved by the knowledge is proposed.The amounts of problem are computed by choice weights,state transfer probabilities,or degrees of fuzzy memberships.The proposed formula of knowledge performance is similar to that of entropy computing.A numeric example is given which shows consistency with impression on human of knowledge use.If the knowledge is used to solve more than one problem,its knowledge performance is kept the same.This result is anticipated by share property and reuse property of knowledge.The proposed formula may be used to quantitative analysis of core knowledge or primitive knowledge performance in education,informatics and management and economic activity.
