In the last years, the vision of the Semantic Web fostered the interest in reasoning over growing sets of assertional statements in ontologies. Traditional tableau-based reasoning systems have problems to answer queries over large ontological data sets, because these systems are based on efficient use of in-memory structures. The purpose of this thesis is to investigate how to release the memory burden from tableau-based reasoning systems and perform efficient instance checking and instance retrieval over SHI-ontologies. Modularization techniques are proposed and algorithms for reasoning over updatable ontologies developed. A prototypical implementation is used for evaluation with respect to benchmark and real world ontologies.
