public final class RecommendToAnonymous
extends AbstractOryxResource

Responds to a GET request to /recommendToAnonymous/[itemID1(=value1)](/[itemID2(=value2)]/...)(?howMany=n)(&offset=o)(&rescorerParams=...)

Results are recommended items for an "anonymous" user, along with a score. The user is defined by a set of items and optional interaction strengths, as in EstimateForAnonymous. Outputs contain item and score pairs, where the score is an opaque value where higher values mean a better recommendation.

howMany, considerKnownItems and offset behavior, and output, are as in Recommend.
