How to reason from inconsistent ontologies with prioritized assertional bases?
Résumé
In many applications, such as video processing, assertions are often provided by several and potentially conflicting sources having different reliability levels. This paper deals with the problem of handling inconsistency in lightweight ontologies when the set of assertions (facts) is prioritized. We propose a safe and efficient way to restore consistency using the concept of free assertions; assertions that are not involved in conflicts. Our approach allows the selection of one consistent assertional base, called a preferred repair. Selecting a unique repair is important since it allows an efficient handling of queries. The last part of the paper contains an illustrative example using video data.
