Hello, hereby we announce the 3.1 release of DBpedia. As always, downloads are available at [1] and the list of changes since DBpedia 3.0 is in our changelog [2]. Some notable improvements are a much better YAGO mapping, providing a more complete (more classes assigned to instances) and accurate (95% accuracy) class hierarchy for DBpedia. The Geo extractor code has been improved and is now run for all 14 languages. URI validation has switched to the PEAR validation class. Overall, we now provide 6.0 GB (58,4 GB uncompressed) of downloadable nt and csv files. The triple count (excluding pagelinks) has surpassed the 100 million barrier and is now at 116.7 million triples, which is an increase of 27% compared to DBpedia 3.0. The extraction was performed on a server of the AKSW [3] research group. I would like to thank Sören Auer, Jörg Schüppel, Chris Bizer, Richard Cyganiak, Georgi Kobilarov, Christian Becker, the OpenLink team, and all other contributors for their DBpedia support.
