Hi All,
I have a usecase where I would like to group the documents based on the Topics.
I thought to try Mahout CVB for the same so that I can get the topics as well
the Documents associated with Topic.
The algo run fine and output is generated but facing some difficulty in
interpreting it correctly for the further use.
I have created 10 Topics.
Topic|Term Dump:
Command: /mahout-distribution-0.7/bin/mahout vectordump -i
/stuti/ClusteringOutput/cvb/CVBoutput -dt sequencefile -d
/stuti/ClusteringOutput/data-vectors/dictionary.file-0 -o ~/vectordump
--printKey TRUE -u true
Output

According to my understanding, the output is fine. Now my queries are :
1. How to get top terms for every Topic from Topic|Term output
2. How to inference which document belongs to which Topic from document|Topic
output.
3. Is there any inbuild utility like Clusterdump which can show the document of
same topics together under a cluster
As my goal is to Group the documents related with same topics together.
Please help me understanding this output.
Thanks
Stuti Awasthi
