Sentiment Analysis

Determine sentiment on the document or entity-specific level

Sentiment Analysis

Overview

Sentiment detection at all levels

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.

What if the film review covers several movies? Which movies were more positively received than others? Here, Rosette applies entity extraction to identify the movies and determines the sentiment for each one by relating the sentiment in the review to each entity. Our sentiment analysis provides entity-level analysis for 18 entity types out of the box, but can be retrained to extract and analyze custom entity types on-premise.

Who really cares?

Sentiment analysis is widely applied to reviews and social media for a variety of applications:

  • Buyer satisfaction and product recommendations
  • Call centers and support communities
  • HR systems to predict employee churn
  • National security to monitor signals for threat or risk
  • Financial risk and volatility
  • Political polling and election predictions
  • Market trends and disruptions
