Frank Scholten commented on MAHOUT-845:
---------------------------------------

I agree that the original solution is too invasive and the feature you are describing is nice for inspection.

One suggestion I have is to separate the JSON formatting from retrieving the top terms.

> When working with Mahout text clustering I find that I keep writing code similar to the contents of
> public static String getTopFeatures(Cluster cluster, String[] dictionary, int numTerms)
> in ClusterDumper in order to determine cluster labels.
> I think it would be useful if (parts of) this code are added to the cluster or vector API so that you could do something like
> Cluster cluster = ... // get the cluster from seq file iterable
> String clusterLabel = cluster.getTopTerms(1, dictionary); // Do something with the label  
> I think this would make it easier to export and post-process clustering results, like indexing or storing them elsewhere.
> Thoughts?
