Network program aggregation and recommendation system and network program aggregation and recommendation method

The invention discloses a network program aggregation and recommendation system and a network program aggregation and recommendation method. The network program aggregation and recommendation method comprises the following steps of: constructing a network program source based on network program information in a network program server; extracting program characteristic information showing characteristics of programs from a plurality of programs from a local program source and the network program source; establishing a comprehensive preference model capable of displaying manual preference input information, explicit preference feedback information and implicit preference information of a user for the user; and showing a recommended program list with the program characteristic information to the user based on the comprehensive preference model. According to the method and the system, the program source can be expanded, the user can conveniently indentify the programs in which the user is interested, the favorite programs can be preferentially presented, the information selection is more humanized, and the intelligentization and an interaction function are further improved.
