Class SimilarityServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

net.myrrix.web.servlets.AbstractMyrrixServlet

net.myrrix.web.servlets.SimilarityServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public final class SimilarityServlet
extends AbstractMyrrixServlet

Responds to a GET request to /similarity/[itemID1](/[itemID2]/...)?howMany=n(&rescorerParams=...), and in turn calls MyrrixRecommender.mostSimilarItems(long[], int) with the supplied values. If howMany is not specified, defaults to AbstractMyrrixServlet.DEFAULT_HOW_MANY.

Unknown item IDs are ignored, unless all are unknown, in which case a HttpServletResponse.SC_BAD_REQUEST status is returned.

Outputs item/score pairs in CSV or JSON format, like RecommendServlet does.

Since:

1.0
