It was me who originally asked this question concerning document x
document comparisons. Incidentally, someone approached me today
concerning a case of possible plagiarism and if infomap could be used
for this. My idea is it could, but mostly using something such as you
mentioned there - ie, if you have enough documents in your corpus -
including the suspected case of plagiarism, it should be possible to
find out which document yields the greatest similarity.

Anyway, the suggestion was put forward by entering the document of
comparison as a full plaintext parameter in the 'associate' program.
(ie: associate ... -d [document as plaintext]". This would be a 'crude
way' of doing comparisons.

Let me know if you find anything, and if you succeed in getting those
vector representations and scalar products.

Cheers,

Mich
