# Sentiment and Emotion Tracker using Natural Language Understanding
## DEPRECATED: this repo is no longer actively maintained. It can still be used as reference, but may contain outdated or unpatched code.
Sentiment and Emotion application detect sentiment and emotions from people's digital footprints (e.g., online reviews and social media text) with [IBM Waston](watson) Technology. The application can reveal the overall emotion and sentiment patterns from a text of interest, including the changes and details of positive or negative sentiment and emotions of "anger", "disgust", "sadness", "fear" and "joy".
Give it a try! Click the button below to fork into IBM DevOps Services and deploy your own copy of this application on Bluemix.
## Getting started
1. You need a Bluemix account. If you don't have one, [sign up][sign_up].
2. Download and install the [Cloud-foundry CLI][cloud_foundry] tool if you haven't already.
3. Edit the `manifest.yml` file and change `` to something unique. The name you use determines the URL of your application. For example, `.mybluemix.net`.
```yaml
applications:
- services:
- my-nlu-service
name:
command: npm start
path: .
memory: 512M
```
4. Connect to Bluemix with the command line tool.
```sh
cf api https://api.ng.bluemix.net
cf login
```
5. Create and retrieve service keys to access the [Natural Language Understanding][service_url] service:
```none
cf create-service natural-language-understanding free my-nlu-service
cf create-service-key my-nlu-service myKey
cf service-key my-nlu-service myKey
```
6. Create a `.env` file in the root directory by copying the sample `.env.example` file using the following command:
```none
cp .env.example .env
```
You will update the `.env` with the information you retrieved in steps 5.
The `.env` file will look something like the following:
```none
NATURAL_LANGUAGE_UNDERSTANDING_USERNAME=
NATURAL_LANGUAGE_UNDERSTANDING_PASSWORD=
```
7. Install the dependencies you application need:
```none
npm install
```
8. Start the application locally:
```none
npm start
```
9. Point your browser to [http://localhost:3000](http://localhost:3000).
10. **Optional:** Push the application to Bluemix:
```none
cf push
```
After completing the steps above, you are ready to test your application. Start a browser and enter the URL of your application.
