Database inconsistency measures and their applications

Abstract

We investigate the measuring of inconsistency of formal sentences, a field with increasing popularity in the literature about computer science, mathematics and logic. In particular, we look at database inconsistency measures, as featured in various publications in the literature. We focus on similarities and differences between inconsistency measures for databases and for sets of logic sentences. Also some differences to quality measures are pointed out. Moreover, we pace some characteristic applications of database inconsistency measures, which are related to monitoring, maintaining and improving the quality of stored data across updates.
