Research

Besides the research in the project Corporate Semantic Web, Corporate Semantic Collaboration, I work on query optimization in RDF repositories. The results include the SPARQL query graph model for representing and rewriting SPARQL queries and a cost model to estimate the cost for invoking pattern based indexes.
Formerly, I worked at Humboldt-Univarsität zu Berlin, Databases and Informationsystems.
