Problems solved by technology

[0012] 2. For explicit modeling, there is a big problem, that is, "cold start". Specifically, it means that for users who have just registered, there is no or too little scoring feedback, so it is impossible to draw a shaped preference model from it. At the beginning of the model, there will be obvious recommendation error bias
[0013] 3. For implicit modeling, only the inference of whether the user is interested in the corresponding information can be obtained through the user's browsing behavior, but the degree of user interest cannot be obtained
[0015] 1. Weak initiative
Since the current recommendation technology is mainly content-based search and category browsing technology, users must enter keywords or manually search by category to obtain relevant information, and c

Embodiment 1

[0051] figure 1 It is a flow chart of the network program aggregation and program recommendation method according to Embodiment 1 of the present invention, refer to below figure 1 Each step of the method is described in detail.

[0052] In step S110, the network program information is obtained from the network program server to construct the network program source locally.

[0053] In this step, the network program information is obtained from the network program server where the program is located, the network program information is aggregated, and the network program source is constructed locally, which is used together with the local existing local program source as the program source. In this embodiment, the programs may include movies, TV dramas, music, broadcasts, audiobooks, etc. in the multimedia form of video, audio, text or a combination thereof. It is preferable to use the C / S (client / server) mode to communicate with the network program server, and to use web craw...

Embodiment 2

[0103] Figure 7 It is a functional block diagram of the network program aggregation and program recommendation system of the present embodiment, combined below Figure 7 Describe in detail the composition of the system.

[0104] Network program aggregation and program recommendation system 1 is mainly composed of the following four functional modules: program feature representation module 10 , network program aggregation module 20 , user preference comprehensive learning module 30 , and active recommendation module 40 .

[0105] The program feature representation module 10 is used to extract program feature information representing program features from multiple programs in local program sources and network program sources. Preferably, the program feature representation module 10 includes a data storage module 11 for storing program description files, a local program resource module 12 for storing local program resources, and a network program resource module 13 for storing ...

Abstract

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.

Description

technical field [0001] The invention relates to the field of network multimedia, in particular to a network program aggregation and program recommendation system and method. Background technique [0002] With the vigorous development of my country's radio and television industry, the multi-level program broadcasting system of the central, provincial, prefectural and county levels has been gradually improved, and the number of channels is increasing. Under the current coding and modulation system, the transmission capacity of the cable digital TV system can reach 500-600 programs. Although this meets the viewing needs of various users, it also makes it difficult for users to find the programs they really like among so many programs. At the same time, users hope to see more of their favorite programs, but the current source of programs is very single. Therefore, how to obtain rich program sources is also a problem that needs to be considered. In view of the above, the establi...
