google-cloud-language

Google Cloud Natural Language API (docs) reveals the structure and meaning of text by offering powerful machine learning models in an easy to use REST API. You can use it to extract information about people, places, events and much more, mentioned in text documents, news articles or blog posts. You can use it to understand sentiment about your product on social media or parse intent from customer conversations happening in a call center or a messaging app. You can analyze text uploaded in your request or integrate with your document storage on Google Cloud Storage.

The Cloud Natural Language API currently supports English, Spanish, and Japanese for sentiment analysis, entity analysis, and syntax analysis.
