twitter sentiment analysis

khaled123

I have an excel sheet that contains a list of tweets and the sentiment of each tweet represented as "1" which is positive and "-1" which is negative. bare in mind that the tweets are in the Arabic language. 
so how can I make RapidMiner determine whether these tweets are positive or negative?
