"Where can I find a tutorial on using RapidMiner for sentiment analysis?"
My interest is in doing sentiment analysis by keyword on web-based data. My primary inputs are RSS-feeds. No web crawling is needed as I have an continuous feed on topics that are of most interest. From my review of the documentation and the examples, it unfortunately isn't clear how I can make this happen.
So, where can I find a tutorial or a how-to guide that will alllow me to build a sentiment analysis model?
