    Hi @iwuejs, I would look into the Text Mining course on the RapidMiner Academy:
    https://academy.rapidminer.com/learn/course/text-and-web-mining-with-rapidminer

    Also look into the Text Processing extension on the Marketplace and also install the Operator Toolbox.

    In particular it sounds like you'll want to be using something like Process Documents or a similar operator to generate the word frequency list - you could also do some stemming and transform case here. For themes, I would look into topic analysis (we have a couple of LDA method operators). Co-occurrence of words sounds like you will need to generate n-grams.

    Hope this helps!

    Best,

    Roland
