Description

The NRC Valence, Arousal, and Dominance (VAD) Lexicon includes a list of more than 20,000 English words and their valence, arousal, and dominance scores. For a given word and a dimension (V/A/D), the scores range from 0 (lowest V/A/D) to 1 (highest V/A/D). The lexicon with its fine-grained real- valued scores was created by manual annotation using best–worst scaling. The lexicon is markedly larger than any of the existing VAD lexicons. We also show that the ratings obtained are substantially more reliable than those in existing lexicons.
