Rakuten

20. Inside DBpedia
RDF
Data Store
Wikipedia

All soccer players,
who played as goalkeeper for a club
that has a stadium
with more than 40,000 seats
and who are born in a country with
more than 10 million inhabitants

22. DBpedia Sample - Query & Result
From Rakuten Ichiba

23. Problems on using LOD in Japan
No Japanese version DBpedia
Less LOD in Japan

24. Created DBpedia-like data by ourselves
(Its in Japanese!)
Solr + RDF Store =
Hybrid
