Class AllItemSimilarities

java.lang.Object

net.myrrix.web.AllItemSimilarities

All Implemented Interfaces:

Callable<Object>

public final class AllItemSimilarities
extends Object
implements Callable<Object>

A simple command-line program that will compute most similar items for all items. 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 item ID is written on line to start. Following that, similar items are written in item,value format on subsequent lines. The next item ID follows and so on.

Example usage:

java -Xmx2g -cp myrrix-serving-x.y.jar net.myrrix.web.AllItemSimilarities --localInputDir=[work dir] --howMany=[# similar items] --rescorerProviderClass=[your class]
