clusters_kMeans.txt is an overview of 20 clusters. Interpretation:
1) n=23019
2) c=[aaaaaaaaaaa:0.002, ...
3) Top Terms: software => 16.595137777966098
ad 1) number of emails in a cluster
ad 2) the values of tfidf for nonempty coordinates of the centroid, sorted
alphabetically
ad 3) Coordinates with the highest tfidf - maybe perceived as cluster's labels

> For Taming Text, I've commissioned some benchmarking work on Mahout's
> clustering algorithms. I've asked the two doing the project to do all the
> work in the open here. The goal is to use a publicly reusable dataset (for
> now, the ASF mail archives, assuming it is big enough) and run on EC2 and
> make all resources available so others can reproduce/improve.
> I'd like to add the setup code to utils (although it could possibly be done
> as a Vectorizer) and the publication of the results will be put up on the
> Wiki as well as in the book. This issue is to track the patches, etc.
