Abstract
We present an implementation platform for query-answering in default logics. The overall approach along with its implementation, the XRay system, allows for query-answering from default theories supporting local proof procedures. The deductive power of XRay stems from it susage of Prolog Technology Theorem Proving Techniques (PTTP) supported by further enhancements, such as default lemma handling and regularity-based truncations of the underlying search space. The generality of the approach, allowing for a (simultaneous) treatment of different default logics, stems from a novel model-based approach to consistency checking.
