I am learning mallet and I am trying out the example. So, I ran this command
bin/mallet import-dir --input sample-data/web/* --output web.mallet
from the link http://mallet.cs.umass.edu/import.php
The output I got is a file named web.mallet but it is not in readable format. It is web.mallet: java serialization data, version 5 . How to convert into a feature vector which can readable or into a csv file or text file.
