Hi Bianca,
In addition to Paul's answer:
There is a full text search facility, a OpenRefine
compliant reconciliation API, a sparql endpoint and a linked data fragment server all
accessible (with examples) from the home page at
http://kbodata.be/.
You can easily fire SPARQL queries at the KBO fragments server through our online client:
http://client.linkeddatafragments.org/#startFragment=http%3A%2F%2Fdata.kbod…
Some examples are included; this might help you discover what's in there.
Best,
Ruben
