Tag: Sentiment Analysis

Sentiment analysis, or opinion mining, is an NLP task that automates the recognition and understanding of the attitudes and opinions expressed in a human-generated text. It evaluates the subjective attitude of a given text as positive, negative, or neutral. Sentiment analysis can be used to turn unstructured text such as customer reviews, social media posts, news articles into structured opinions for in-depth analysis and visualization.

Rosette can analyze the sentiment in different languages at the document or entity level. It returns a sentiment label along with a confidence score between 0 and 1.
