Notes about Sentiment polarity

Recently, we are going through the materials about Sentiment Polarity. This is really an interesting topic. Here are few notes about this topic.

• Dimensions

We need aspects to quantify a word’s characteristic. Here are the 3 aspects positive, objective and negative for telling the word’s characteristic (in digits).

If we claim this word is positive, we believe this word will be used on telling something good. On the other hand, if we claim this word is negative, we believe this word will be used on telling something bad. However, if we claim this word is objective, we believe that this word tells us nothing about any subjective attitude.

• Graphical representation of Sentiment Polarity

There is a website which show you how to represent a word in 3 dimensions spaces.

Point to note that is they are using triangular graph instead of Cartesian coordinate system.

If you are not familiarize this type of presentation, here are my interpretations.

* As much as objective, as less as subjective value

Fact is a fact. There are no good or bad for a fact since this is an objective stuff. Actually, the triangular shape is telling you this behavior.

* Subjective value is either positive or negative or neither of them (IE both of them are zero)

Despite the objectiveness controls the level of subjective value, subject value must be either positive or negative or both of them are zero.

* What's next

After you can categorize the wording, you can get a bunch of digits. Then, you can do further analysis by using k-clustering, term weighting extra.
