Many database applications tolerate a certain nlnount of data inconsistency to gain increased concurrent processing and to accommodate realworld constraints. This paper describes how inconsistency can be modeled in a database and managed with. consistency westoration methods. The correctness criterion for the maintenance of inconsistency is epsilon serializability (ESR). An inform.al notation t...

Central in standard possibilistic logic (where propositional logic formulas are associated with lower bounds of their necessity measures), is the notion of inconsistency level of a possibilistic logic base. Formulas whose level is strictly above this inconsistency level constitute a sub-base free of any inconsistency. Some extensions, based on the notions of paraconsistent completion of a possi...

In this paper, I will characterize a new class of inconsistency–adaptive logics, namely inconsistency–adaptive modal logics. These logics cope with inconsistencies in a modal context. More specifically, when faced with inconsistencies, inconsistency–adaptive modal logics avoid explosion, but still allow the derivation of sufficient consequences to adequately explicate the intended part of human...
