The Effect of Negators, Modals, and Degree Adverbs on Sentiment Composition

Understand

Negators, modals, and degree adverbs can significantly affect the sentiment of the words they modify.

• Often, their impact is modeled with simple heuristics; although, recent work has shown that such heuristics do not capture the true sentiment of multi-word phrases.
• We created a dataset of phrases that include various negators, modals, and degree adverbs, as well as their combinations.
• Both the phrases and their constituent content words were annotated with real-valued scores of sentiment association.
