A lexicon based [see page 16, approach] to sentiment analysis. It uses grade adverbs to amplify or weaken an emotion word.
For the gradable approach the lexicon can have a range of possible values for each word. They can range from some upper maximum and some lower minimum. This approach also applies a few rules to account for intensifiers.
Rules work like function transformations. When a rule is evaluated its transformation is applied to the orientation of the rest of the words around it. We [see page 20, define] the following rules:
| Rule | Description |
|---|---|
| Negation | Inverse and reduce the weight when the word not is nearby. |
| Capitalisation | All Caps are stronger than normal case. |
| Intensifier | Strengthen the weight of the modified word. |
| Diminisher | Weaken the weight of the modified word. |
| Exclamation | Number of exclamations intensifies weight!!! |
| Emoticon | Emojis have meaning too you know :P |
