Usage

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.

You can now access your recommendation engine in php:

// Instanciate the Myrrix service
$myrrix = new MyrrixService('localhost', 8080);

// 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]])

java -jar myrrix-serving-x.y.jar --localInputDir /path/to/working/dir --port 8080 --userName test --password 1234
