I've installed the gem but am not getting very good results with my
limited use. In particular, I tried the example you posted on your
blog:
Clusterer::Clustering.kmeans_clustering(["hello world","mea
culpa","goodbye world"])
but it appears to have placed all three strings in the same cluster;
the result was [[0, 1, 2]]. I get a similar result ([[1, 0, 2]]) if I
try the hierarchical clustering instead.
This is on Mac OS X 10.4, running Ruby 1.8.4.
