Abstract
We apply a selection of 19 inconsistency measures from the literature on artificially generated knowledge bases and study the distribution of their values and their pairwise correlation. This study augments previous analytical evaluations on the expressivity and the pairwise incompatibility of these measures and our findings show that (1) many measures assign only few distinct values to many different knowledge bases, and (2) many measures, although founded on different theoretical concepts, correlate significantly.

Note that \(C_{K}\) is equivalent to the Kendall’s tau coefficient [8] but scaled onto [0, 1].
- 5.
We only considered the inconsistent knowledge bases from \(\hat{K}\) as all measures assign degree 0 to the consistent ones anyway.
