Yes, you are totally right, I have mistaken the meaning of the method, and it
works out perfectly as I construct it as the transpose. Really appreciate your
help, thanks!

Subject: Re: How can I retrieve item-pair after calculating similarity using
It looks like your code is making 1 Row per item, which means that
columnSimilarities will compute similarities between users. If you
transpose the matrix (or construct it as the transpose), then
columnSimilarities should do what you want, and it will return meaningful
indices.
