Axiom pinpointing has been introduced in description logics (DLs) to help the user to understand the reasons why consequences hold and to remove unwanted consequences by computing ...
Completion algorithms for subsumption are investigated for many extensions of the description logic EL. While for several of them subsumption is tractable, this is no longer the ca...
