Hope this helps Currently Carrot2 Workbench does not support clustering files directly from a local folder. There are a few solutions here:

To fix this issue You need to put the names of fields to cluster on in your solrconfig.xml. To replicate the configuration that worked for you in Carrot2 Clustering Workbench, put these in your clustering request handler (or provide in the query URL):
code :
<!-- In Workbench this is "Title field name" -->
<str name="carrot.title">name</str>

<!-- In Workbench this is "Summary field name" -->
<str name="carrot.snippet">features</str>

this one helps. Carrot2 does not use the conventional notion of document-document similarity, so you won't find it there. You can indeed use the term-document matrix to compute all sorts of document-document similarity.
You are correct in assuming that the columns of the term-document matrix are in the same order as the documents in the input list. You can check the source code to clear any other doubts.

wish helps you There's no special tokenizer for this, you'll need to tokenize labels on your own. Tokenizing on white space will be a good choice in most cases.

This might help you To get more clusters, try increasing the values of the maxClusters and maxBaseClusters parameters. Here's how to pass parameter values in Java code.
However, the low number of clusters may also be caused by the characteristics of your input data (too few documents?). To verify this, try clustering your data with the Lingo algorithm.
