Prof. Dr. Christian Bizer  

Overview

Christian Bizer explores technical and economic questions concerning the development of global, decentralized information environments. His current research focus is the evolution of the World Wide Web from a medium for the publication of documents into a global dataspace. The results of his work include the Named Graphs data model which was adopted into the W3C SPARQL recommendation; the D2RQ mapping language which is widely used for publishing relational databases to the Web of Data; the Silk - Linking Framework, and the Berlin SPARQL Benchmark for measuring the performance of RDF stores. Christian Bizer has initialized the W3C Linking Open Data community effort which is interlinking large numbers of data sources on the Web. He also co-founded the DBpedia project which derives a comprehensive knowledge base from Wikipedia. Christian Bizer obtained his doctoral degree with a dissertation on information quality in the context of Web-based Systems. Christian Bizer has joined the University of Mannheim in June 2012. Before moving to Mannheim, he was Juniorprofessor at Freie Universität Berlin.
