Hi All,

I am trying to do sentiment analysis on text messages (text mining) using rapid miner.
Example: If message is "Apple rocks" we should be able to rate this statement as positive. Similarly if message is "Apple is not fast" this can be rated as negative.

Please let me know if you have some solution or samples available.
Or any other alternative can be used.

Regards,
Sagar

    Hi,

    you may also want to have a look at the new book "Data Mining for the Masses" by Matthew North. He explains data mining with RapidMiner from the very beginning: http://www.amazon.de/Data-Mining-Masses-Matthew-North/dp/0615684378
    Otherwise, you should tell us where exactly you have problems and where you don't understand the tutorials, so we can help you.

    Best, Marius

    We are developing a project under academic who is using sentiment analysis. We use the tool RapidMiner however we have some difficulty in creating the process. It will be useful to use a dictionary of words in order to relate to the other users' opinions? How to implement?
    thank you

    Hi Saddam,

    you information is a bit sparse - what is your input data, what do you have so far, where exactly do you get stuck? Which documentation/tutorial materials did you use? Please also post the process that you created and describe what you expect it to do, and where the problems occur.

    Concerning the dictionary, can you please describe more detailed, what you are thinking about?

    Best regards,
    Marius
