Ontologies play a key role in the infrastructure of the Semantic Web

for sharing precisely defined terms which can be made accessible to
automated agents. For ontologies with complex knowledge to represent
and reason with, errors due to inconsistencies become quite common,
and these inconsistencies can be intrinsically different. While
there are Description Log.css reasoners that can detect
inconsistencies in input ontologies, they do not help classify
and/or summarize the nature of the inconsistencies that are present.

In this paper, we propose a novel technique based on Shapley values
to measure inconsistencies in ontologies. This measure can be used
to identify which axioms in an input ontology or which part of these
axioms need to be removed or modified in order to make the input
consistent. We also propose optimization techniques, such as
partitioning, to improve the efficiency of computing Shapley values.
The proposed techniques are independent of a particular ontology
language and are independent of a particular reasoning system used.
Application of this method can improve the quality of ontology
diagnosis and repair in general.
