In this extended abstract an optimization technique, the so-called signature calculus, for reasoning with number restrictions in description logics is investigated. The calculus i...
Abstract. We show that the description logic SOQ with number restrictions on transitive roles is decidable by a terminating tableau calculus. The language decided by the calculus i...
Qualitative temporal and spatial reasoning is in many cases based on binary relations such as before, after, starts, contains, contact, part of, and others derived from these by r...
The Situation Calculus and the Fluent Calculus are successful action formalisms that share many concepts. But until now there is no formal relation between the two calculi that wo...
