Construction and Querying of Relational Schema for Ontology Instances Datach, and present an algorithm of automatic relational schema building for ABox data. We also developed query processor that rewrites SPARQL queries to SQL queries and has some inferencing capabilities. Tests on our prototype system demonstrate that the rewritten queries can be answered by RDBMS in an

Instance-Based Ontology Matching Using Regular Expressions [EM07] or [DMDH04] use the information provided by instances in their matching algorithms. Due to the fact that ontologies offer the possibility to model instances within the ontology, these should definitely be used to increase the accuracy of the matching results. Additionally, the set of instanc
