Abstract
The increasing availability of a large number of interactive multi-media information services means that users have a large and diverse collection of choices open to them. This diversity and choice may present navigation difficulties to users which can dissuade them from using such services. One method of assisting users to navigate through large collections is to use information filtering to extract only the information relevant to an end-user according to his/her long-term preferences. In this paper, we describe a mechanism to acquire a user's long-term preferences (user profile), and then show how the acquired profile may be used to recommend selections that may be of interest to the user. The profile is acquired on the basis of a user's habits using a Heuristic-Statistical approach, and is used to create selection indices which are then used during on-line interactions to recommend selections. Our mechanism has been incorporated into an experimental Video On Demand (VOD) service that is implemented using a client-server architecture. The profile acquisition component is incorporated into a VOD server on a multi-tasking machine, while the VOD user interface resides on a personal computer. Our mechanism for acquiring profiles and making recommendations has been quantitatively evaluated on the basis of data collected about movie preferences.
