INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD, PROGRAM, AND INFORMATION PROCESSING SYSTEM

PROBLEM TO BE SOLVED: To prevent the occurrence of search omission caused by a difference in an expression or a declaration method between an entered searching key and caption information. SOLUTION: Each second metadata 165 comprises: a correspondence table 166 denoting a correspondence relation among names of actors/actresses, casting names, in programs such as dramas, names other than the casting names such as nicknames in dramas; and program ID information 164. The correspondence table 166 properly describes talent IDs whereby the names of actors/actresses and talents including the actors/actresses or the like can uniquely be distinguished, the casting names and other names 1 to 3 other than the casting names in the dramas. In the case that the second metadata 165 are used for searching processing even when a user enters any text data among "Makoto Fujiyama", "Taro XX", "operative XX", and "Daddy" as the text data being a searching key, the user can obtain the same searching result including any of the text data "Makoto Fujiyama", "Taro XX", "operative XX", and "Daddy". This invention can be applied to home servers. COPYRIGHT: (C)2006,JPO&NCIPI
