English abstract:
Description logics (DLs) make the assumption that what is not known to be true is unknown. This is adequate when dealing with incomplete data. However, if the data is assumed to be complete, the closed-world assumption (CWA), stating that what is not known must be false, is more appropriate. Real world applications often require that complete and incomplete parts of the data interact with each other, which calls for formalisms that simultaneously support both of these assumptions. In DLs, this can be done by specifying which predicates should be interpreted under the closed-world view. The goal of this thesis is to investigate the effects that adding partial CWA has on reasoning in DLs.
