I am a phd student at the Univ. of Memphis working on a project that I think SAS Text Analytics can help with but I need a little guidance.
Here is what I am trying to do: I have a list of words, about 100. I need to find all the words in a large volume of text (like from a book) that relate to the word in my list. How many times they are related and ideally, whether the relationship is positive or negative. For example: let's say "blue" is in my reference list and there is a sentence in the text that is, "The car is blue." Then "car" is related to "blue" and the relationship is positive, If the sentence was, " The car is blue" then the relationship would be negative.
I am not sure if what I am asking is possible or if SAS is the right program to use. I would imagine my project would be similar to brand affinity which I have seen SAS used for. Any suggestions would be greatly appreciated.

The article pointed me in the right direction. I still need to figure out the programing details. Sentiment Analysis is a separate module from SAS 9.3. Thanks
