I tried "money", because that seems pretty related to investor and also to mark (a monetary unit, not only German, but also an old English/Scottish equivalent of 13s 4p, if you can make sense of that), but the strength is only 16% and 2%, according to whatever embedding model they use.
similarly "scam" is only 2% related to mark
I'd expect scam to be squarely in the middle between investor and mark :D
I expected Germany to link to 'mark' (i.e. the former currency), but apparently not.
"scam" was my first try, too. I would have thought it would be strongly related to both "investor" and "mark"?
I feel like the two are already equal in certain circles (eg the crypto space) so, as many comments are pointing out, understanding how relationships are built is important. That being said, if the black box is revealed, it’s not really a guessing game any more.
