How exactly is the final result caluculated? (using the demo code http://sentiwordnet.isti.cnr.it/code/SentiWordNetDemoCode.java)

What does the term sense signify?(the number after #)

Answer 1

Briefly, the process mainly consists of two steps:

• a semi-supervised learning step: they start from two sets of 7 sense which are paradigmatically positive and negative and using the WordNet relations they spread positivity and negativity accordingly.
• a random-walk step: by considering WordNet a graph they perform a random-walk algorithm in which the labels positive and negative can possibly change, till convergence.

You can find more details about how the final score is computer in the related scientific paper.

The #sense field refers to the numeric sense ID in WordNet, since SentiWordNet is based on it.
