Model contractions on description logics
Falappa, Marcelo Alejandro - Moguillansky, Martín O.

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	When using tableaux algorithms to reason about Description Logics (DLs), new information is inferred from the models considered while trying to achieve knowledge satisfiability. By focusing the ontology change problem, we consider an environment where DLs are the logical formalization…
