Abstract |
We investigate the extension of Description Logics (DL) with a notion
of ``substitution''. Substitutions naturally arise when reasoning
about programs which modify graph structures that are characterized by
DLs. They constitute also a means to express concept and role
modifications such as addition or deletion of individuals
(respectively, pairs of individuals) to or from
concepts (respectively, roles). After a formal definition of
substitutions, we conduct a systematic study of a wide range of DLs
with the purpose of proving or disproving conservativity of an
extension of the respective DL with substitutions. The resulting
classification is a gauge of the expressiveness of description logics
and their adequacy for reasoning about change of graph structures.
