1. problem analysis
 infobox param -> DBpedia property <->/-> Wikidata property
 infobox param <-> Wikidata property (publish with release)
2. (later) inclusion of DBpedia into Wikidata (sameaAs and owl:equivalent(P|C))

Completed Tasks


Getting ready:

First Release:

  • DONE provide Python code for reference extraction (Krzysztof, Wlodzimierz)
  • DONE deployment of Mongodb prefusion deployed (Marvin)
  • DONE publish reference dump and deploy a micro-service for current Python extraction as is `?article=http://en.wikipedia.org/wiki/Arthur_Schopenhauer` outputs csv as is (Wlodzimierz)
  • DONE deploy DIEF (extraction framework) micro-service on the GFS server (Johannes)
  • DONE (blogpost) - Mongodb prefusion - example queries (Marvin)
  • DONE - Study and Categorization (Tina)

Study / Scouting for good examples:

  • DONE - see preliminary study of sync tartgets
  • problem: four layers of complexity: Subject variation / fixed vs. varying property / reference (inferred from 1 and 2) / normalisation of values (currency, inch/cm, ...)
    • NBA Players and Cloud types (Tina)
    • Videogames (easy disambiguations)
    • films 100k budget is fixed and revenue parameter varies in language
    • Cars & Products (complex)
    • organisations (page for a group)
    • Sports
    • Cities (easy disambiguation)
  • Difficult examples:
    • subjects/articles are of a different granularity
      • city & population: core, close area and county
  • integration of MusicBrainz:
    • DONE check how well it is mapped (Johannes)
  • DONE check NBA sources using google structured data tool - see here (Tina)

Second Release:

  • DONE edit FactualConsensusFinder so user can insert Wikipedia URIs (Marvin)


  • DONE draft release note
  • DONE news + feedback squad, talk page, email, lists
  • DONE Wikimania 16-18 August | Stockholm, Sweden (Johannes will go)
