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.

Why is "The car is blue." positive, but "The car is blue" negative?

Sorry, that was supposed to be: If the sentence is, "The car is NOT blue," then the relationship is negative.

CORRECTION: The last line of the second paragraph was supposed to be: If the sentence is, "The car is NOT blue," then the relationship is negative.

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
