  First, the control unit 16A determines whether or not an entry word has been input via the input unit 11 (S51). If it is determined in step S51 that the entry word has been input, the first reading unit 30A reads the body of the entry word and reads the related phrase associated with the entry word ( S52). On the other hand, if it is not determined in step S51 that a headword has been input, the process returns to step S51 again. After step S52, the first extraction unit 31A extracts nouns from the text and related phrases (S53).

  After step S53, the second reading unit 30B performs reading of the text when the extracted noun is used as a headword, and reading of related words / phrases associated with the extracted noun (S54). After step S54, the second extraction unit 31B extracts nouns from the text and related phrases (S55).

  After step S55, the determination unit 241A determines whether there is a noun extracted T times or more (S56). That is, the determination unit 241A determines whether the same noun is extracted a plurality of times specified by the extraction by the first extraction unit 31A and the extraction by the second extraction unit 31B.

  If it is determined in step S56 that it has been extracted T times or more, the search unit 24A sets the input headword and the noun extracted T times or more as keywords (S57). On the other hand, if it is not determined in step S56 that the extraction has been performed T times or more, the series of processes is terminated.

  After step S57, the search unit 24A searches for a television program from the electronic program guide using the keyword (S58). After step S58, the display control unit 25 displays the search result on the display unit 13 (S59). After step S59, the recording reservation unit 26 determines whether designation of a television program for which recording reservation is to be made has been received (S60). If it is determined in step S60 that the instruction has been accepted, the recording reservation unit 26 executes recording reservation for the television broadcast (S61).

  After step S61, the first association unit 28 associates the data of the electronic program guide related to the searched television program with the keyword used for the search (S62). After step S62, the series of processes is terminated.

  On the other hand, if it is not determined in step S60 that the instruction has been received, the control unit 16 determines whether or not an input for instructing the end of the recording reservation process is received via the input unit 11 ( S63). If it is determined in step S63 that an input for instructing the end is accepted, a series of processing ends. On the other hand, if it is not determined in step S63 that the input for instructing the end has been received, the process returns to step S60 again.
