Expressive ABox Reasoning with Number Restrictions, Role Hierarchies, and Transitively Closed Roles
We present a new tableaux calculus deciding the ABox consistency problem for the expressive description logic ALCNHR+ . Prominent language features of ALCNHR+ are number restricti...

Nonmonotonic Ontological and Rule-Based Reasoning with Extended Conceptual Logic Programs
We present extended conceptual logic programs (ECLPs), for which reasoning is decidable and, moreover, can be reduced to finite answer set programming. ECLPs are useful to reason ...

Extending Conceptual Logic Programs with Arbitrary Rules
We present extended conceptual logic programs (ECLPs), for which reasoning is decidable and, moreover, can be reduced to finite answer set programming. ECLPs are useful to reason ...

A logical framework for modeling and reasoning about semantic web services contract
In this paper, we incorporate concrete domain and action theory into a very expressive Description Logic (DL), called ALCQO. Notably, this extension can significantly augment the ...
