Hi Sverker, Yes, I believe that the vectors *are* normalized post-SVD. I don't know offhand where this happens; I'm CC'ing the infomap-nlp-users list in the hope that someone else does. Otherwise I'll try to figure this out when I get a chance... please prod me if you haven't heard anything in a couple of days.
