New DBpedia 3.2 Release: Airpedia & wikidata
Today, friday the 21th 2013, is online the version 3.2 of the Italian DBpedia.
Main changes from 3.1:
- Updated data from Wikipedia’s dump of 06/05/2013;
- Updated mappings and ontology to latest ones:
- Use of Wikipedia Data Extractors (bleeding edge v 3.9, git commit 97c0a3cc);
rdf:typeinformation from Project Airpedia; that permitted resources with unmapped templates to show an estimated type, derived with a Machine Learning algorithm; those resources are marked with proprerty
http://airpedia.org/ontology/is_estimated_type(set to “true” or unavailable). Moreover we will have also confidence information triples like
http://airpedia.org/ontology/type_with_conf#9, where conf# is in range from 6 to 10 (10 meaning that other international DBpedias have a similar page with manually mapped type).
- There are
owl:sameAstriples to the Wikidata pages, the collaborative database from MediaWiki; for pages not available we still have some interwikilinks (although 1/10 of the previous release).
