In this paper we formalise compilation of the conjunctive bodies of a restricted class of Horn rules into updates on terminologies. This involves a pre-processing of the graphs re...
This paper demonstrates the applicability of automated reasoning to text processing, specifically to Question Answering. It is shown that the approach is feasible, effective, and ...
We consider two recently proposed definitions of the expressive power of description logics, one due to Baader, the other due to Kurtonina and de Rijke. The proposals are non-equi...
DLP (Description Logic Prover) is an experimental description logic knowledge representation system. DLP currently implements a superset of propositional dynamic logic as well as ...
We describe a method for characterizing the expressive power of description logics. The method is essentially model-theoretic in nature, and it is applied to obtain expressiveness...
