RECOMMENDATIONS UTILIZING META-DATA BASED PAIR-WISE LIFT PREDICTIONS
First Claim
1. A system for facilitating item recommendations, comprising:
- a metadata component that obtains metadata associated with a base item and a candidate item; and
a pair-wise lift predictor component that predicts pair-wise lift as a function of the metadata of the base item and the candidate item.

Abstract
The subject disclosure pertains to systems and methods for facilitating generation of item recommendations based at least in part upon pair-wise lift. Pair-wise lift is a measure of correlation between a pair of items and is generally calculated based upon past usage data. If usage data is insufficient or unavailable, pair-wise lift for a pair of items can be estimated based upon metadata associated with the items. In other aspects, pair-wise lift can be used to generate an explanation for recommended items. An explanation for an item recommendation can be based upon common metadata features associated with the item pair. The relative impact each metadata feature has on predicted pair-wise lift can be evaluated to determine the common feature(s) most likely to have caused the item to be recommended.

13. A method for generating explanations for item recommendations, comprising:
-
obtaining a base item and a recommended item; identifying at least one common feature of the base item and the recommended item based at least in part upon metadata associated with the base item and the recommended item; predicting pair-wise lift as a function of the metadata; determining the effect of the at least one common feature on the predicted pair-wise lift; and generating an explanation corresponding to the recommended item based upon the effect of the at least one common feature. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A system for facilitating generation of recommendations, comprising:
-
means for estimating an occurrence count for a base item and an occurrence count for a candidate item as a function of metadata; means for estimating a pair-wise count for the base item and the candidate item as a function of the metadata; and means for generating an estimated pair-wise lift based upon the base occurrence count, the candidate occurrence count and the pair-wise count.
