Google Natural Language API

Derive insights from unstructured text using Google machine learning. Natural Language uses machine learning to reveal the structure and meaning of text. You can extract information about people, places, and events, and better understand social media sentiment and customer conversations. Natural Language enables you to analyze text and also integrate it with your document storage on Cloud Storage.

Setup:

1. Sign-up for a Google Cloud account and setup the Natural Language API.

2. Sign-up for a PubNub account, if you don't have one already

   1. Select Functions

   2. Select your desired App and Keyset

   3. Select "Explore Templates" and proceed with selected integration.

3. Start the Integration Function module.

4. Try a test message (you can click on Publish to do this).

Walkthrough:

This Integration Function is setup to listen to a specific PubNub channel (CHANNEL-to-text-google-analyze) but you can configure it to listen to all channels or a subset, using wildcards, e.g. chat.*. Thus, you can add comprehension even in private chats and other secure communication channels. The Integration Block is flexible in that it can be used both as part of a PubNub messaging flow, i.e. as part of publishing data, as well as accessed separately through a REST endpoint. Additionally, customization of capabilities can be done through publish message metadata or REST query parameters. In publish metadata, the customization properties are set as part of a JSON object specific for the function named google-text-analyze-v1.
