信息关系与病态信息判定准则

Information Relationships and Criteria for Determining Poor Quality Information

从大规模信息集合的质量问题出发 ,研究了用于病态信息检测的信息关系 :信息单元限定、单向制约关系、双向制约关系、非突变关系、组合关系、顺序关系、子集关系、表达式关系、函数关系 ,以及复合关系与外部定义关系等。讨论了用于病态信息判定的准则 :合法性、合理性、真实性和正确性等 。

Starting from the quality problems of large-scale information set, this paper studies the information relationships for checking poor quality information, including information unit self-restriction, one-way restriction, two-way restriction, non-catastrophic relationship, combination relationship, sequence relationship, subset relationship, expression relationship, functional relationship, compound relationship and external defining relationship. The paper alse discusses the criteria for determining poor quality information involving validity, rationality, authenticity and correctness, which lays a good foundation for future research and experiments.
