Christian Bizer explores technical and empirical 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. Christian Bizer initialized the W3C Linking Open Data community effort which is interlinking large numbers of data sources on the Web. He co-founded the DBpedia project which derives a comprehensive knowledge base from Wikipedia. He also initialized the WebDataCommons project which monitors the deployment of RDFa, Microdata, and Microformat data on the Web by analyzing large Web crawls. Further results of his work include the Named Graphs data model which was adopted into the W3C RDF and SPARQL recommendations; the D2RQ mapping language which is widely used for publishing relational databases to the Web of Data; the Silk - Identity Resolution Framework, the Berlin SPARQL Benchmark, and the Mannheim Search Join Engine. Christian Bizer holds an appointment as full professor at the University of Mannheim, where he leads the Focus Group Web-based Systems of the Data and Web Science Group. Before moving to Mannheim, he headed the Web-based Systems Group at Freie Universität Berlin.
