SPLM is a ranked opinion lexicon. We obtained the weights assigned to each word-tag pair by making use of the equations defined on the following paper which describe all details about this lexicon.
The file is tab delimited with:
Word: the words.
Tag: Part of speech (POS),
- r (adverb)
- a (adjective).
Polarity: positive / negative.
- D(w): the final weight of the word according to the equations described in the following paper:
If the value of D(w) is negative, w will be in the class of negative words. If the value of D(w) is positive, w will be in a positive class.
