Description Logics with Concrete Domains and Aggregation
Abstract. We extend different Description Logics by concrete domains (such as integers and reals) and by aggregation functions over these domains (such as min;max;count;sum), which...

Issues of Decidability for Description Logics in the Framework of Resolution
Abstract. We describe two methods on the basis of which efficient resolution decision procedures can be developed for a range of description logics. The first method uses an orderi...
