currently on IBM Bluemix using NodeJS, ExpressJS,Jade templating, and the Twitter API.

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.

Deploy to Bluemix

Getting Started

  1. Create a Bluemix Account

[Sign up][sign_up] in Bluemix, or use an existing account. Watson Services in Beta are free to use.

  1. Download and install the Cloud-foundry CLI tool

  2. Edit the manifest.yml file and change the <application-name> to something unique.

- services:
- personality-insights
name: <application-name>
command: node app.js
path: .
memory: 128M

The name you use will determinate your application url initially, e.g. <application-name>

  1. Connect to Bluemix in the command line tool
$ cf api
$ cf login -u <your user ID>
  1. Create the Personality Insights service in Bluemix
$ cf create-service personality_insights "IBM Watson Personality Insights Monthly Plan" personality-insights-service
  1. Push it live!
$ cf push

See the full [Getting Started][getting_started] documentation for more details, including code snippets and references.

Running locally

The application uses Node.js and npm so you will have to download and install them as part of the steps below.

  1. Copy the credentials from your personality-insights-service service in Bluemix to app.js, you can see the credentials using:

    $ cf env <application-name>

    Example output:

      "personality_insights": [{
          "credentials": {
            "url": "<url>",

        "label": "personality_insights",
        "name": "personality-insights-service",
        "plan": "IBM Watson Personality Insights Monthly Plan"

  3. Go to the project folder in a terminal and run: npm install

  4. Start the application

  5. node app.js
