GlobalFactSyncRE - DBpedia, which frequently crawls and analyses over 120 Wikipedia language editions has near complete information about (1) which facts are in infoboxes across all Wikipedias (2) where Wikidata is already used in those infoboxes. GlobalFactSyncRE will extract all infobox facts and their references to produce a tool for Wikipedia editors that detects and displays differences across infobox facts in an intelligent way to help sync infoboxes between languages and/or Wikidata. The extracted references will also be used to enhance Wikidata.


DBpedia Association

The DBpedia Association was founded in 2014 to support DBpedia and the DBpedia Community. Since then we are making 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.

Sebastian Hellmann (DBpedia Association and AKSW/KILT) has completed his PhD thesis under the guidance of Jens Lehmann and Sören Auer at the University of Leipzig in 2014 on the transformation of NLP tool output to RDF. Sebastian 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. He also is the executive director and board member of the non-profit DBpedia Association. Sebastian is contributor to various open-source projects and communities such as DBpedia, NLP2RDF, DL-Learner 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 80 peer-reviewed scientific publications (h-index of 21 and over 4300 citations) and started the Wikipedia article about Knowledge Extraction. He’s based in Leipzig, Germany.
