Consider a dummy data-set:
Text | Sentiment
Wow That is amazing | Positive
That was worst! | Negative.
Can we build a sentiment classifier using Logistic regression algorithm?
Are there other MS Data Mining algo's that I should consider?
Your thoughts and comments are appreciated!

You cannot build good sentiment analysis system simply by extracting different terms from the sentence and applying one of the data mining algorithms in SQL Server. You have to look at the whole sentence to understand if it is positive or negative. Examples:
The product is good
The product is not good.
The product does not look very good.
No one thinks that the product is good.
The product is not only good but amazing.
The product provides value.
The product provides little value.
