Actually a qualitative content analysis or thematic analysis is a manual process. It is not possible to use regex or tokenizing or stemming rules since it is based on meanings and not wording or the the occurence of words.
e.g. a sentence like "I feel tingling in my gutt and my heart beat stronger when I see him" and "sitting besides her, just knowing she is there makes med relax and feel that I am home" both might be coded as "In love" in a specific topic.
What you do when you perform qualitative analysis is reading the text, mark the beginning and the end of the specific part you are to code (That could be one or several posts in a table), and then define the code in another field (Where you preferrable would be able to either have a list of codes to select from but just as easily could write a new code.)
It is the next steps you need help from a program: You want to get the texts presented according to the codes, you want to be able to add another level of coding where you cathegorize the codes or use them as subcodes, but still be able to see the texts tha are coded similarly, etc.
The question is if whether JMP is able to help me in this? I understand JMP can perform a lot of textanalysis close to AI but what I seen of it is that all these are more or less automatic.
