信息差及其在产品信息质量评价中的应用

Information Difference and Its Applications in the Assessment for Product Information Quality

在对企业信息进行全面分析的基础上提出了信息差的概念 ,基于信息差提出一种权重系数确定法并给出具体计算步骤。该方法可有效确定三种评价产品信息质量指标 (准确性、及时性和信息价值 )中参变量之间的权重 ,为科学评价产品信息的质量奠定基础。最后通过应用实例加以说明。

We proposed a concept of information difference (ID) based on comprehensive analysis of enterprise information. According to the rationale of ID, this paper presented a method to determine the weights. The method can be applied in the process that calculates three indicators such as accuracy, timeliness and value, and contributes to the scientific evaluation of product information quality (PIQ). An illustrative example was given to demonstrate how this method can be used to evaluate PIQ.
