# Sentiment Analysis

Named Entity Recognition Sentiment Analysis allows you to find whether text has positive, negative, or neutral sentiment. For example, you can use it to determine whether users of a particular product or service are satisfied or not, based on an automated analysis of reviews.

The sentiment analysis grammar files contain dictionaries of types of words (such as positive adjectives, negative nouns, and so on), and patterns that describe how to combine these dictionaries into positive and negative phrases.

Named Entity Recognition has sentiment analysis grammar files available in the following languages:

- Arabic
- Chinese
- Czech
- Dutch
- English
- French
- German
- Italian
- Portuguese
- Russian
- Spanish
- Turkish
