Abstract

A method to determine demographic information of a new user utilizing only ratings includes training an inference engine informed with a training data set which includes ratings and demographic information from a plurality of other users. The new user inputs ratings, such as movie ratings, and an inference engine determines demographic information of the new user. The demographic information of the new user can then be used to provide recommendations or to provide targeted advertisements to the new user.

Technical field [0002] The present invention generally relates to user profiling and user privacy in recommender systems. More specifically, the present invention relates to demographic information inference. Background technique [0003] Research has been conducted on inferring user demographics in different contexts and for generating data for multiple types of users. In the context of interactive networks, a chart structure that helps infer demographics using link-based information for blogs and social network data from Facebook has been shown. Other work relies on text features derived from the user's handwriting to infer demographics. [0004] The main disadvantage of text-based infer...
