Abstract

The increasing availability of a large number ofinteractive multi-media information services means thatusers have a large and diverse collection of choices open to them.This diversity and choice may present navigation difficulties to userswhich can dissuade them from using such services.One method of assisting users to navigate through largecollections is to use information filtering to extract only theinformation relevant to an end-user according to his/her long-termpreferences. In this paper, we describe a mechanism to acquire auser‘s long-term preferences (user profile), and thenshow how the acquired profile may be used to recommend selectionsthat may be of interest to the user. The profile is acquired onthe basis of a user‘s habits using a Heuristic-Statisticalapproach, and is used to create selection indices which arethen used during on-line interactions to recommend selections. Our mechanismhas been incorporated into an experimental Video On Demand(VOD) service that is implemented using a client-serverarchitecture. The profile acquisition component isincorporated into a VOD server on a multi-taskingmachine, while the VOD user interface resides on apersonal computer. Our mechanism for acquiring profiles and makingrecommendations has been quantitatively evaluated on thebasis of data collected about movie preferences.
