Google Cloud Natural Language API

API

Advanced natural language understanding for sentiment, entity, and syntax analysis

Overview

The Google Cloud Natural Language API offers RESTful endpoints for analyzing unstructured text. It supports sentiment analysis (score/magnitude), entity recognition (with types like person/organization/location), and syntax parsing (parts of speech, dependencies). Responses are JSON-formatted. Use cases include analyzing customer feedback sentiment, extracting key entities from documents, categorizing content, and enhancing search relevance. It integrates with other Google Cloud services and supports multiple languages.

Example Integration (JavaScript)

script.js JS


fetch('https://cloud.google.com/natural-language/docs/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
