# Sentiment Analysis

Linguistic sentiment analysis (LSA) is a tool based on Named Entity Recognition that you can use to identify positive or negative sentiments in text. Sentiment analysis is available as Named Entity Recognition grammar files, in various major languages.

The sentiment analysis grammar files define positive and negative sentiments. Some of them have components defined, which allow you to extract attributes from matched phrases, such as topic, subject, and positive or negative sentiments.
