Answer 1

Hi Shiv,

both, GATE and RapidMiner are powerful text mining and sentiment analysis tools. I personally prefer RapidMiner, because I found it easier to learn and the RapidMiner training courses provided by Rapid-I gave me a really quick start. They offer a dedicated course on text mining and sentiment analysis: Sentiment Analysis, Opinion Mining, and Automated Market Research .

Starting in September or October 2009, they will also offer webinars. You should contact them directly, if you would like to learn more about their webinars. Several major online market research companies in Europe and the US are using RapidMiner for opinion mining and sentiment analysis from internet discussions groups and web blogs. For more details and references I would again suggest to simply ask their team at contact(at)rapid-i.com or check their RapidMiner forum.

Best regards,

Frank
