Abstract. We give an optimal (exptime), sound and complete tableaubased algorithm for deciding satisfiability with respect to a TBox in the logic ALCI using global state caching. ...
We develop a formal system dealing `spatially' with certain aspects of uniformity and control during knowledge acquisition. To this end, we study an appropriate modality, whi...
It has been shown that it is possible to exploit Independent/Restricted And-parallelism in logic programs while retaining the conventional "don't know" semantics of...
