Do a singular value decomposition of a term by document matrix. ;-) Or better yet, try something else, like Independent Component Analysis (ICA) which many people find to work better. I'm always hoping to see a paper that shows that LSA works better than a simple cosine measure, but somehow the vast majority of LSA papers never do that basic comparison... ;-) STeVe -- http://mail.python.org/mailman/listinfo/python-list
