We propose a technique to make consistency detection scalable for large Aboxes in secondary storage. We use static analysis of knowledge representation with summarization techniqu...
Tree automata are often used for satisfiability testing in the area of description logics, which usually yields ExpTime complexity results. We examine conditions under which this ...
This work is motivated by the task of describing in natural language a concept defined in an OWL DL ontology. However, rather than focussing on linguistic issues, we address the q...
Highly optimized reasoning support for Description Logics (DLs) has been developed during the past years. This paper presents our efforts to develop a reasoner suitable for mobile ...
Sonic1 is the first prototype implementation of non-standard inferences for Description Logics that can be used via a graphical user interface. In addition to that our implementat...
We show how a tableaux algorithm for SHIQ can be extended to support role boxes that include range and domain axioms, prove that the extended algorithm is still a decision procedur...
