Embodiment

[0068] refer to figure 2 , In a family, multiple family members share the IPTV portal service, and the service is generally provided by a "set-top box". Through steps 1 to 4 of the present invention, the playing history records of the "set-top box" are analyzed to identify multiple context users, and steps 5 to 8 use the identified context information to generate a program recommendation list to the context users.

[0069] For example, in a family there are: old people, children and middle-aged people, they share IPTV portal services and accumulate certain historical records; through steps 1 to 4, three contexts are identified: the old people are used to watching historical dramas in the morning, record c1; Children like to watch cartoons at noon, record c2; middle-aged people are used to watching gunfight movies at night, record c3.

Abstract

The invention discloses an IPTV (internet protocol television) program recommendation method based on context recognition for multiple users. By means of clustering analysis to program viewing time, the time slots at which the viewing times of users are concentrated relatively are acquired, different users' preferences to programs at different time slots are computed, similarity of the preferences to programs at the different time slots is analyzed, the time slots of the similar programs viewed by users are combined into a new context, and then recommendation is made according to the information of the context. Therefore, to some extent, problems about multiple users in IPTV portal service are solved, and recommendation quality is improved.

Description

technical field [0001] The invention relates to the technical field of IPTV (Interactive Personality TV) recommendation, in particular to an IPTV program recommendation method based on multi-user context recognition. Background technique [0002] In IPTV services, with the continuous explosive growth of IPTV programs, TV will once again become the center of home entertainment. However, because the input function of the remote control terminal is relatively weak, and sometimes users do not know what they want to watch, It is difficult for users to find the content they need and like.

Commonly used collaborative filtering techniques are: collaborative filtering based on browsing history and collaborative filtering based on content. At present, the main recommendation technology is based on the use, improvement ...
