SentiWords is a high coverage resource containing roughly 155.000 English words associated with a sentiment score included between -1 and 1. Words in this resource are in the form lemma#PoS and are aligned with WordNet lists (that include adjectives, nouns, verbs and adverbs). Scores are learned from SentiWordNet and represent state-of-the-art computation of words' prior polarities (i.e. polarity for non-disambiguated words) using SWN.  SentiWords was built using the method described in Guerini et al. (2013) and the dataset presented in Warriner et al. (2013). For a thorugh description see Gatti et al. (2015).
