I am doing sentiment analysis using Twitter data. I am attaching the dataset below. I have replaced hashtags, links and @usernames. After that I want to use the Process Documents from data operator inside which I want to transform the case of all the tweets to lower case. But on running the process, the transformation to lowercase is not happening. the data remains the same. It seems like the Process Documents from data operator is not working. 
Inside the subprocess operator: 


here is what the data looks like after replacing the hashtags, links and @usernames:

    Are you able to attach the process you are doing? It's much better if we take a look at what you are doing and begin fixing from that than trying to do that by ourselves. :) It saves time and effort. Thanks in advance.

    All the best,

    @rfuentealba I am attaching the xml process below:

    Sir I need urgent help

  • rfuentealbarfuentealba RapidMiner Certified Analyst, Member, University Professor Posts: 568 Unicorn

    It works.
    • Switched the Nominal to Text operator right after the Read Excel operator, and before the Subprocess.
    • After the Subprocess, I switched the "keep text" flag to true.
    That's pretty much everything I did.

    Please, find attached.

    I attached what worked for me in the previous post. Here is a new version. Just import it and configure it to your dataset.

    All the best,

    Rodrigo.
