Re: Knowledge Graph links to Freebase

Great detective work!
Actually, (apart from systems that don't have base64), I think you will find there are some characters at the start of the id file that include backspace - can't imagine why they would do that!

Anyway, as it is Sunday of a holiday weekend:
http://sameas.org/ggraph/?key=H4sIAAAAAAAAAONgVuLQz9U3MKs0LgIAXXSnTQwAAAA
(It's not pretty, as it probably isn't useful - if someone wants it to do something else I can change it).

Best
