System, method, and non-transitory computer readable storage medium, for diversifying complementary item recommendations based on user preferences

Abstract

A method including determining, in real-time, a diversity preference score for a user based at least in part on an anchor item chosen by the user via a user interface executed on a user device of the user. The method also can include determining, in real-time, a comparison result between the diversity preference score and a diversity preference threshold. The method further can include generating, in real-time, a personalized recommendation pool based on (a) the comparison result, (b) a complementary recommendation pool generated based at least in part on the anchor item, and (c) a diversity objective function. In many embodiments, when the comparison result indicates that the diversity preference score is greater than the diversity preference threshold, the diversity objective function can be associated with cross-domain diversity. In a number of embodiments, when the comparison result indicates that the diversity preference score is not greater than the diversity preference threshold, the diversity objective function can be associated with within-domain diversity. The method additionally can include transmitting, in real-time through the computer network, the personalized recommendation pool to be displayed with the anchor item on the user interface. Other embodiments are disclosed.
