摘要/Abstract

摘要： 针对序信息系统，基于优势关系给出了知识协调度和知识差异度的概念，为刻画和度量序意义下知识之间的协调程度和差异程度提供了一种新方法。讨论和分析了这些度量的性质及它们之间的关系，通过实例表明了上述度量的有效性。这些结论将有助于序信息系统的知识发现研究。

Abstract: In ordered information systems based on dominance relation the concepts of knowledge consistency and knowledge difference are defined，which provide a new method to characterize and measure the degree of consistency and difference between knowledge.The important properties of these measures are discussed and the relationships between these measures are analyzed.In addition，the effectiveness of these measures is shown by the examples.These results will be helpful for studying for knowledge discovery on ordered information systems.

Key words: ordered information system, knowledge consistency, knowledge difference
