About the Association

The DBpedia Association was founded in 2014 to support DBpedia and the DBpedia Community. Since then we are making slow, but steady progress towards professionalizing DBpedia for its users and forming an effective network out of the loosely organised DBpedia community. The DBpedia Association is currently situated in Leipzig, Germany and affiliated with the non-profit organisation Institute for Applied Informatics (InfAI) e.V. If you are interested in details, please read the Charter of the DBpedia Association or contact us via dbpedia@infai.org.

Current Board Members

Prof. Dr. Sören AuerBefore being appointed Director of TIB, Sören led the “Enterprise Information Systems (EIS)” department at Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS and held a Chair in Enterprise Information Systems at the University of Bonn. After studying Mathematics and Computer Science at Hagen, Dresden and Yekaterinburg, Sören earned a PhD in Computer Science at Leipzig University. This was followed by posts as post-doctoral researcher at the University of Pennsylvania and at Leipzig University, where he led the “Agile Knowledge Engineering and Semantic Web” (AKSW) research group.
Prof. Dr. Christian BizerChristian 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. He 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 and he also initialized the WebDataCommons project which monitors the adoption of schema.org, RDFa, JSON-LD, Microdata, and Microformats on the Web by analysing large Web crawls. His technical research focuses on the integration of data from large numbers of Web data sources and includes topics such as information extraction, identity resolution, schema matching, data fusion, and data search. 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.
Prof. Dr. Heiko PaulheimHeiko is Chair of the Web Data Mining Group at the University of Mannheim. This group focuses on the curation, refinement, and use of Web-scale knowledge graphs. His group developed large-scale resources like DBkWik and CaLiGraph, and frameworks such das RDF2vec. He is involved in different national and international projects which utilize knowledge graphs in various scenarios, from analyzing the societal impact of AI to supporting mixed teams of AIs and humans in Industry 4.0. Heike is also the Program Director of Mannheim Master in Data Science, which was one of the first Data Science Master degree programs in Germany.
Kingsley IdehenKingsley is Founder, President, and CEO of OpenLink Software, a privately held company he started in 1992. 
OpenLink Software is an industry acclaimed technology innovator and leading provider of Data Access, Integration, and Management technologies such as  Virtuoso, Data Access Drivers for ODBC and JDBC, Structured Data Sniffer, YouID, and more.
Dr. Dimitris KontokostasDimitris was a Knowledge Engineer and Semantic Web researcher at University of Leipzig and the DBpedia Association before he started working for Diffbot in 2019. His (research) interests focus around knowledge representation and knowledge management of large-scale knowledge graphs and data quality. Dimitris is a co-editor of SHACL, the upcoming W3C recommendation for data validation and the creator of RDFUnit, a popular tool and unit-testing framework for RDF validation.
Dr.-Ing. Sebastian HellmannSebastian is a senior member of the “Agile Knowledge Engineering and Semantic Web” AKSW research center, which currently has 50 researchers (PhDs and senior researchers) focusing on semantic technology research – often in combination with other areas such as machine learning, databases, and natural language processing. Sebastian is head of the “Knowledge Integration and Language Technologies (KILT) Competence Center at InfAI. Sebastian is contributor to various open-source projects and communities such as DBpedia, NLP2RDF and OWLG and wrote code in Java, PHP, JavaScript, Scala, C & C++, MatLab, Prolog, Smodels, but now does everything in Bash and Zsh since he discovered the Ubuntu Terminal. Sebastian is the author of over 50 peer-reviewed scientific publications (h-index of 18 and over 3500 citations) and a not-yet-deleted Wikipedia article about Knowledge Extraction. Sebastian was chair at the Open Knowledge Conference in 2011, the Workshop on Linked Data in Linguistics 2012, the Linked Data Cup 2012, the Multilingual Linked Data for Enterprises 2012 workshop, the NLP & DBpedia Workshop 2014, the SEMANTiCS 2014, SEMANTiCS 2015, SEMANTiCS 2016 and SEMANTiCS 2017 conference as well as the KEKI Workshop 2016.
Prof. Dr. Jens LehmannJens leads the „Smart Data Analytics“ research group at the University of Bonn and Fraunhofer IAIS with 50 researchers. His research interests involve Semantic Web, machine learning, question answering, distributed computing and knowledge representation.
