Sample code: Analyze text with the Watson Personality Insights service

Use the node.js API for the Watson Personality Insights service


Interactive code: When you see Run at the top of a code sample, you can run the code, check the results, make changes, and run it again. When you see Deploy, you can deploy the code into the developerWorks IBM Cloud account.

About this code

This code shows you how to use the node.js API for the Watson Personality Insights service. Given some text, Watson analyzes the openness, conscientiousness, extraversion, agreeableness, emotional range, and needs of the speaker.

The code has two basic sections:

  1. The main() method. This is the entry point to the code. It creates the PersonalityInsightsV3 object and then invokes the profile() method.
  2. A set of default parameters and the code that runs this module if it is invoked by itself (as opposed to being invoked by a require() statement). See the node.js documentation for more information on the implications of the require.main === module statement.
Show result

This code takes a string as input and analyzes the personality of the speaker. The call to the Watson Personality Insights service is wrapped in a JavaScript Promise to handle the asynchronous nature of the service.

See the overview of the Personality Insights service or the github repo for the Watson node.js API for more information.

Try changing the text to see what happens.

Using this code once deployed

To use this code once you've deployed it, you must create an instance of the Watson Personality Insights service:

To invoke the code, pass a JSON structure that matches the defaultParameters object as shown above with the following changes:

  1. The username, password, and url fields must be filled in with the credentials for your Personality Insights service instance.
  2. The use_unauthenticated field must be false.

For more information, see the developerWorks tutorial Invoking actions on the IBM Cloud Functions platform.
