Installation and configuration

Get the Bundle via Composer

The best way to use the library is via Composer.

Do in the command line:

composer require bcc/myrrix-bundle

Or Manually add the library to your dependencies in the composer.json file:

{
    "require": {
        "bcc/myrrix-bundle": "*"
    }
}

Then install your dependencies:

composer install

Add the bundle to your kernel

// app/AppKernel.php
public function registerBundles()
{
    return array(
        // ...
        new BCC\MyrrixBundle\BCCMyrrixBundle(),
        // ...
    );
}

Set the configuration

You will have to configure your Myrrix endpoint in your configuration:

# app/config/config.yml
bcc_myrrix:
    host: localhost # the myrrix host
    port: 8080      # the myrrix port
    username: test  # the myrrix username
    password: 1234  # the myrrix password

Start a Myrrix server instance

Before you start, don't forget to have an instance of the Myrrix server running. Simply download the .jar excecutable for the serving layer and run it:

java -jar myrrix-serving-x.y.jar --localInputDir /path/to/working/dir --port 8080

It will run a server on port 8080 and using the /path/to/working/dir directory as a backing storage. You can get more information about the server here.

Usage

You can now simply get an instance of MyrrixService:

$myrrix = $container->get('bcc_myrrix.service');

// Put a user/item assocation, here use #101 as an association of strength 0.5 with item #1000
$myrrix->setPreference(101, 1000, 0.5);

// Refresh the index
$myrrix->refresh();

// Get a recommendation for user #101
$recommendation = $myrrix->getRecommendation(101); // an array of itemId and strength (example: [[325,0.53],[98,0.499]])

• Recommendation to many users
