However it's not terribly worth having this unless/until we have more than one clustering system to evaluate, is it?

If not, is there a reason you think LSA will work best? You talk about eliminating words that occur rarely in documents — could we have a quick-and-dirty approach that looks at the within-corpus frequency of terms? (If multiple different approaches makes sense, we'll end up having each encapsulated as a class or similar, in the same way we're doing with Clusterer. It's worth having an idea of this up front, in case it changes the approach.) > 3) Hierarchical Clustering > Since the clustering API is already in place, I would like to implement a hierarchical clusterer to cluster the search results. Do you have a particular approach you think is a good one? Are you thinking agglomerative or divisive? J -- James Aylett devfort.com — spacelog.org — tartarus.org/james/
