Abstract

The present invention provides a broadcast television subscriber grouping system and method based on spectral clustering integration. The system comprises: an input unit, for inputting audience preference parameters; a program database, for storing program playing information; an audience rating database, for collecting program watching information from subscribers; an audience preference space construction unit, for calling a data source from the program database and the audience rating database according to an attributive character index input by the input unit, and obtaining attributive character index data of the subscribers for the types of programs, thereby forming a preference matrix; a first grouping unit, for grouping the subscribers multiple times based on the audience preference space; a matching unit, for performing a consensus match on clusters in a grouping set by using a consensus function, so as to construct a cluster relationship diagram; a second grouping unit, for converting the cluster relationship diagram into a cluster relationship degree matrix, which is used as a similarity matrix, and for grouping the clusters by using a spectral clustering method; and an integration unit, for setting a group as a group in which a data point is located, wherein the number of occurrences of the data point in a cluster in the group is greatest.

Description

technical field [0001] The present invention relates to the field of radio and television, and more specifically, to a radio and television user grouping system and method based on spectrum clustering integration. Background technique [0002] With the development of the radio and television industry and the continuous enrichment of TV resources, users have formed different program type preferences during the viewing process. By analyzing user viewing behavior, grouping users, finding user groups with different viewing habits, and recommending personalized programs has become the research focus of the radio and television industry. [0003] Cluster analysis is to divide objects into multiple classes or clusters according to the degree of closeness in nature, so that the data within a class or cluster has a high degree of similarity, and the data between classes or clusters has a high degree of dissimilarity. Analysis has been successfully applied to many fields such as info...
