Sentiment Analysis

Sentiment refers to the attitudes, opinions, and emotions of a person towards a person, place, thing, or other entity. These are subjective impressions, not facts. Rosette returns sentiment scores for entire documents, or for individual entities within a larger body of text.

A document refers to a body of text that expresses sentiment such as a review of a film, a political editorial, a Facebook status or a short tweet. An “awesome new movie” is positive, but a “disastrous political scandal” has a negative sentiment.
