Keyword Matching Is Basic

The keyword matching function in the Sentiment score plugin is basic.

The matching of keywords is basic, and does not understand English grammar, just certain words within it. Therefore you should only use the sentiment score as a guideline.

• The plugin does not handle modifiers. For example, "This is good" produces the same score as "This is very good."
• The plugin does not handle negatives. For example, in the phrase "This is not good", only "good" is matched, resulting in a positive sentiment score.
• Repetition of keywords increases the score. For example, "good good cake" scores twice as much as "good cake".
• Contradictory sentiments are cancelled out. For example, "scared but happy" will match scared = -2 and happy = +3, resulting in a total of +1.
