public class PMILexiconExpander
extends TweetToFeatureVector

Calculates the Pointwise Mutual Information (PMI) semantic orientation for each word in a corpus of tweets annotated by sentiment. The score is calculated by substracting the PMI of the target word with a negative sentiment from the PMI of the target word with a positive sentiment. BibTeX:
