Word Affect Intensities
Table 1: Example entries for four (of the eight) emotions in the NRC Affect Intensity Lexicon. For each emotion, the table shows every 100th and 101th entry, when ordered by decreasing emotion intensity.
['Word  [ITALIC] outraged', 'Anger 0.964', 'Word  [ITALIC] horror', 'Fear 0.923', 'Word  [ITALIC] sohappy', 'Joy 0.868', 'Word  [ITALIC] sad', 'Sadness 0.844']
: For each item, the score is the proportion of times the item was chosen as having the most intensity minus the proportion of times the item was chosen as having the least intensity. The scores range from -1 to 1. Since degree of emotion is a unipolar scale, we linearly transform the the -1 to 1 scores to scores in the range 0 to 1. We refer to the full list of words along with their real-valued scores of affect intensity as the NRC Affect Intensity Lexicon. The lexicon has about 12,000 entries with about 1500 entries for each of the eight emotions. Observe that the intensity scores have a normal distribution. The histograms for other emotions have a similar shape. The lexicon is made freely available for, non-commercial, research purposes.
