I am using the mahout to cluster the news and I could see the top

topic for each cluster? Do we have to hardcore the topic for the
cluster?
I find an interesting sitehttp://search.carrot2.org/stable/search
and they make excellent topics clustering based on the page content.
You can use Carrot2 to generate labels for clusters, but in my
experience it has issues with the size of individual elements in the
dataset is large. Carrot2 is optimized for clustering/labeling search
results, and seems to key off the phrases found in titles of web pages
and search summaries.
Next I was going to try to derive SIPs (statistically improbable
phrases) from documents in the cluster, but we ran out of time on that
project.
