Class AllRecommendations

java.lang.Object

net.myrrix.web.AllRecommendations

All Implemented Interfaces:

Callable<Object>

public final class AllRecommendations
extends Object
implements Callable<Object>

A simple command-line program that will compute recommendations for all users. It does not start an instance of the Serving Layer that responds to requests via HTTP. Instead it performs all computations locally, in bulk. This may be useful to create a simple batch recommendation process when that is all that's needed.

Results are written to System.out. Each user ID is written on line to start. Following that, recommendations are written in item,value format on subsequent lines. The next user ID follows and so on.

Example usage:

java -Xmx2g -cp myrrix-serving-x.y.jar net.myrrix.web.AllRecommendations --localInputDir=[work dir] --howMany=[# recs] --rescorerProviderClass=[your class(es)]
