Sample Nodejs Application for the IBM Watson Personality Insights Service

Personality Insights Nodejs Starter Application

The IBM Watson Personality Insights service uses linguistic analysis to extract cognitive and social characteristics from input text such as email, text messages, tweets, forum posts, and more. By deriving cognitive and social preferences, the service helps users to understand, connect to, and communicate with other people on a more personalized level.
