Information Relationships and Criteria for Determining Poor Quality Information
Gao Qi · Systems engineering and electronics · 2002
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.
