2019 talk:Technology outreach & innovation/GlobalFactSync

Key goals: connect infoboxes across language wikipedias to Wikidata, benefiting from the several sources
Knowledge integration and lined data technologies (AKSW/KILT) Center at the Institute for Applied Informatics (InfA) in Leipzig, a DBpedia project
presenter was Johannes Frey
aid synchronization of Infobox facts across Wikipedias
enable import/upstream connections of facts from Wikipedia to Wikidata with references
compare contradictions across these sources and enrichment of missing information
GFS = GlobalFactSync here
example: Wikidata was not update for the release date or publication date of "Boys Don't Cry", a Moulin Rouge song, Q030something
there is a GFS Data Browser, at https://global.dbpedia.org which shows an aggregated view of values and their sources for an attribute
it can give a template for an infobox based on what it sees across these systems about the topic/attributes

DBpedia and reference extraction from Wikipedias
cleans and merge the data, and fuse with Wikidata
import into MongoDB and GFS Data Browser
DBpedia started in 2007 as a crowd-sourced effort to semi-automatically extract structured RDF information which could be queried on the Web in SPARQL
a new mission since 2018: Databus Platform to integrate with other data
DBpedia is a large scale multilingual knowledge base
for more see https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/GlobalFactSyncRE
RDF has subject, predicate, and object
see mappings.dbpedia.org and http://dbpedia.org/ontology/* properties
DBpedia has 8 ontologies, including DBO and ...

their Reference extraction software can get citations from inboxes. it can parse de, en, es, fr, it, nl, pl, pt, ru, and sv

they offer or help offer DBpedia services: fact extractions, reference extractions in JSON or TSV, a MongoDB query endpoin with the entire GFS data for lookups and analytical queries
