Information processing device, method, and program

Abstract

An information processing device includes: extraction means for extracting, from program information, a category feature word being a keyword representing a category feature; identification means for identifying a channel by category based on the category feature word extracted from the program information for a program to be broadcast on the channel; and display control means for exercising control over the channel to be displayed after category classification.

1 . An information processing device, comprising:
 extraction means for extracting, from program information, a category feature word being a keyword representing a category feature;   identification means for identifying a channel by category based on the category feature word extracted from the program information for a program to be broadcast on the channel; and   display control means for exercising control over the channel to be displayed after category classification.   
     
     
         2 . The information processing device according to  claim 1 , wherein
 the identification means identifies the channel by category based on a counting result of the extracted category feature word for each of a plurality of categories.   
     
     
         3 . The information processing device according to  claim 1 , wherein
 the identification means identifies the program by category based on the category feature word extracted from the program information for the program, and based on the category of the program to be broadcast on the channel, identifies the channel by category.   
     
     
         4 . The information processing device according to  claim 3 , wherein
 the identification means identifies the channel by category based on a counting result of the program to be broadcast on the channel for each of a plurality of categories.   
     
     
         5 . The information processing device according to  claim 3 , wherein
 the identification means identifies the channel by category based on a counting result of a broadcast time of the program to be broadcast on the channel for each of a plurality of categories.   
     
     
         6 . The information processing device according to  claim 1 , wherein
 the identification means identifies the channel by category on a basis of the program based on the extracted category feature word, and   the display control means exercises control over the channel to be displayed after classification of a program currently being on the air into any of the categories.   
     
     
         7 . The information processing device according to claim  1 , wherein
 the display control means displays a category list, and exercises control over the channel to be displayed in a list for any one of a plurality of categories selected from the category list.   
     
     
         8 . The information processing device according to  claim 1 , further comprising
 calculation means for calculating a user's degree of preference for the channel based on a history of an operation made to the program broadcast on the channel, wherein   the display control means exercises control over the channel, when the degree of preference is high, to be displayed as a channel belonging to a group different from a plurality of categories.   
     
     
         9 . An information processing method, comprising the steps of:
 extracting, from program information, a category feature word being a keyword representing a category feature;   identifying a channel by category based on the category feature word extracted from the program information for a program to be broadcast on the channel; and   exercising control over the channel to be displayed after category classification.   
     
     
         10 . A program being operable to instruct a computer to execute a process, comprising the steps of:
 extracting, from program information, a category feature word being a keyword representing a category feature;   identifying a channel by category based on the category feature word extracted from the program information for a program to be broadcast on the channel; and   exercising control over the channel to be displayed after category classification.   
     
     
         11 . An information processing device, comprising:
 an extraction unit extracting, from program information, a category feature word being a keyword representing a category feature;   an identification unit identifying a channel by category based on the category feature word extracted from the program information for a program to be broadcast on the channel;   a display control unit exercising control over the channel to be displayed after category classification.
