Usage

Landing page:

Users records their speech.

Analysis of facial expressions, captured on a timed interval during the recording.

By transcribing audio to text, we're able to perform sentiment analysis and extract concepts (next image) from the users speech. Here we perform sentiment analysis of the text:

After reading aloud the first few paragraphs of this NPR article, we extract the following concepts. The sizes of each node represent a relevancy score. Clicking on each bubble will take you to the wikipedia article of that concept.

Payment:

Getting started

1. Clone the latest version

Start by cloning the latest version of Symantixs on your local machine by running:

$ git clone https://github.com/LimpkinBeastMaster/sentimize.git
$ cd symantix

2. Install Dependencies

From within the root directory run the following command to install all dependencies:

$ npm install

3. Setup Environment Variables

Server side setup

1. Copy and save the example.env file in the env folder as development.env.
2. Replace the port with your desired port and enter the login credentials for your MySQL server (make sure it is running)

Client side setup

1. Create a free account on http://face.sightcorp.com/ and create a new application for a new App Key.
2. Copy and save the client-config.example.js file in the env folder as client-config.js.
3. Enter and save your Client ID and App Key in the client-config.js file.

4. Run the application

1. Create a build folder within client/build. From within the root directory run the following command to make sure Browserify builds the bundle file and rebuilds on every change with Watchify:

$ npm run bundle

2. In a new terminal window run the following command to start the application:

$ npm start

After that open in your browser the localhost with your chosen port, e.g. http://localhost:4568/ to access the application.

5. Run tests

Configure the environment variable NODE_ENV prior to running tests.

$ export NODE_ENV=development
$ npm test

You may use npm run test-client or np run test-server to run front-end and back-end tests independently.
