....tree idea is applied in a novel way, where the (second phase of the) construction of the query tree is used to economically instantiate the theory. Our instantiation procedure extends the intelligent grounding module (IG) proposed for the Disjunctive Deductive Database System dlv (Eiter et al. [7]) However, our procedure only applies to nondisjunctive theories. 4.1 Levy s Query Tree A query tree is a compact representation of a search tree for first order Horn theories (Levy et al. 13] Most importantly, the query tree encodes precisely the set of all derivations of a query type p( ....

The dlv system is freely available for various platforms via the dlv homepage [18] More detailed descriptions of other features of the dlv system can be found in [1, 4, 13, 14, 16, 15, 17]. Acknowledgements The authors wish to thank Simona Citrigno for implementing the original version of the diagnosis frontend of dlv. This work was supported by FWF (Austrian Science Funds) under the projects P11580 MAT and Z29 INF. Currently we cannot expect very fast computations, as our ....
