DBpedia Day 2017

SEMANTiCS 2017 will host the 10th edition of the DBpedia Community Meeting on the last day of the conference.  

 Community Meeting

DBpedia is an international crowd-sourced community effort to extract structured information from Wikipedia, Wikidata and Wikimedia Commons and to make this information available on the Web as Linked Open Data.

More than 150 DBpedia enthusiasts joined the 7th Community Meeting, which was co-located with the SEMANTiCS 2016 in Leipzig and the largest DBpedia meeting to date. The success of the last community meetings and the increasing number of specific language chapters proves that the DBpedia community is constantly growing and gaining more and more significance and impact in the Semantic Web Community.
