Hoi,
When the situation is often raised and when there is no answer.. as in not at all. The facts contradict what you say.
I have asked often for statistics. I have often raised this aberration. Truly when I have data to offer, the example of Freebase is enough to turn me off.
I also have made the case why the reluctance of including data is wrong. I have even given a mathematical approach for this and all you hear is
silence
Yes, good work is done. But it is all about the mechanics it is not about looking after the database and its quality and quantify. Leaving all of this only to the "community" is arguably a bad idea.
Thanks,
GerardM
