Lexicon-based approaches to sentiment analysis of text are based on each word or lexical entry having a pre-definedweight indicating its sentiment polarity. We compute sentiment for more than 150,000 English language texts drawn from 4 domains using the Hedonometer, a lexicon-based technique and Azure, a contemporary machine-learning based approach. We model differences in sentiment scores between approaches for documents in each domain using a regression and analyse the independent variables (Hedonometer lexical entries) as indicators of each word's importance and contribution to the score differences.1.
