    Sentiment analysis is 100% possible in RM. There is an operator for this task, and depending on your research, I might recommend labeling your dataset and fitting a model to predict sentiment. Some dictionary-based approaches are simple token lookups, whereas the latter might help you learn the nuances of your domain. Good luck.

    Hi NoorMohammad786. Yes. I do this all the time in RapidMiner. Here is an XML process of one way to get you started. If you want to bring in Excel text data rather than Twitter data, just replace theSearch Twitteroperator with theRetrieveoperator and modify theSelect Attributes. You will also need the Operator Toolkit from the Marketplace for theExtract Sentimentoperator.
