In description logics (DLs), concrete domains are used for defining concepts based on concrete qualities of their instances such as the weight, age, duration, and spatial extensio...
The purpose of this appendix is to introduce (in a compact manner) the syntax and semantics of the most prominent DLs occurring in this handbook. More information and explanations...
Motivated by a chemical process engineering application, we introduce a new concept constructor in Description Logics (DLs), an n-ary variant of the existential restriction constr...
This paper reports on the formal proof of correctness of a compiler from a substantial subset of Java source language to Java bytecode in the proof environment Isabelle. This work ...
This paper proposes constructs that can be used to declaratively specify the disjoint nature of object properties or roles. These constructs may be a useful extension to the Descr...
