Thank you for your article over N-GRAM and more over your way of explanation. Currently, i'm working on sentimental analysis of Review data (Amazon data) on SAS EG. I have completed the process of eliminating stoplist word from raw data and doing N-gram process on data, i did TRI-gram on my data but i'm confuse how to do next step for that output data from n-gram process, my aim is to calculate only frequency(term frequency) of neutral, positive and negative word. so could you please help me with any article or any example.

Regards,
Ranjan
