I am trying to use weka to cluster business terms. I have a file with 12,000 term names and definitions and am looking to group them into broader subject areas as a way to seed a taxonomy. I am experimenting with different clusterers but not getting any interesting results. Typically it creates one cluster or just seems to die without showing output. Any advice for how to get off the ground for a newbie? I have used weka before, but mostly for classification. My efforts to research online haven't yielded much useful info.
Thanks in advance!
