Facilitating discovery of information items using dynamic knowledge graph

Abstract:

A computer-implemented technique is described herein for facilitating discovery of information items. The technique involves providing at least one set of indicators to a user via a user interface presentation. The indicators represent respective topics. Each distance d between a pair of respective indicators, associated with respective topics (t, t'), is based on at least: a similarity between the topic t and the topic t' as expressed by a knowledge graph; and a dynamic and personalized joint measure of the user's current interest in the topic t and the topic t'. The technique further involves providing at least one information item to the user in response to the user's engagement with the user interface presentation.
