Errors with Sentiment Analysis in RapidMiner

Hi, I am currently trying to run sentiment analysis using the Aylien extension on RapidMiner. I am experiencing many errors (such as Aylien rating a review as positive although it is clearly negative and vice versa). My process is setup as follows: Read Excel->Data to Documents->Sentiment Analysis I have spreadsheets with reviews (one review per row) and the process seems to be reading the excel sheets fine and returning individual results as expected. It just seems that Aylien is returning inaccurate polarity results quite frequently. If anyone has any insight on how to fix this problem, please let me know. Thanks in advance!
