User Story:

As a user you would start off by doing semi-automatic categorization of open-ended responses. You then have the option to use that code frame to train your automatic categorization.

However, the automatic categorization might not code all the open-ended responses. The issue here is that there is no way for the user to see which responses were not coded in the automatic categorization.

So, ideally, users should be able to filter based on all responses that were not coded in the automatic categorization so that they can just create new categories in the semi-automatic categorization.
