(First embodiment)
FIG. 1 is a diagram showing a configuration of a recommended destination information distribution system according to the first embodiment of the present invention. The system includes a TV terminal 200 that can view a TV program, a Web terminal 300 that can browse a website on the World Wide Web (WWW), and a destination recommendation device 100 that recommends a specific place name as a destination. , Is included. A portable storage medium 107 can be connected to the TV terminal 200 and the Web terminal 300. The portable storage medium 107 is a rewritable semiconductor storage medium, for example.

  When a TV program is viewed with the portable storage medium 107 connected, the TV terminal 200 stores the TV viewing history 201 in the portable storage medium 107. The TV viewing history 201 is information for specifying a television program viewed by the TV terminal 200. In the present embodiment, the TV viewing history 201 is information representing the date and time of viewing a television program and the channel that was viewed.

  When a web site search is performed with the portable storage medium 107 connected, the web terminal 300 stores the search history 301 in the portable storage medium 107. The search history 301 is a search keyword input by the user when searching for a website.

  The destination recommendation device 100 is a device that operates alone and can be connected to the portable storage medium 107 in the same manner as the TV terminal 200 and the Web terminal 300. When the portable storage medium 107 storing at least one of the TV viewing history 201 and the search history 301 is connected to the movement destination recommendation apparatus 100, the movement destination recommendation apparatus 100 uses the daily interest information based on the storage contents of the portable storage medium 107. To collect. The destination recommendation device 100 recommends a destination based on the daily interest information collected in this way.

  FIG. 2 is a block diagram illustrating a configuration of the movement destination recommendation apparatus 100. The destination recommendation device 100 includes a control circuit 101 including a CPU and a main storage device, and a nonvolatile memory 102, a hard disk drive (HDD) 103, an input device 104, a portable storage medium interface ( I / F) 105, a display device 106, and a program information acquisition device 108.

  The nonvolatile memory 102 is a nonvolatile storage medium such as a flash memory. The non-volatile memory 102 stores a control program to be executed by the CPU of the control circuit 101. The HDD 103 is a storage device that is read and written by the control circuit 101. The HDD 103 stores in advance a keyword database (DB) 117 that associates genre names with keyword groups, and a place name DB 118 that stores place names such as prefectures and city names.

  The input device 104 is an input device such as a keypad or a touch panel, and transmits an input signal to the control circuit 101 in accordance with a user operation. The portable storage medium I / F 105 is an interface for reading information stored in the portable storage medium 107. The control circuit 101 can read the TV viewing history 201 and the search history 301 from the portable storage medium 107 via the portable storage medium I / F 105. The display device 106 is a display device such as a liquid crystal monitor. The program information acquisition device 108 acquires program information of a specific program using, for example, an EPG (electronic program guide) system. The program information acquisition device 108 may acquire program information by receiving program information from the outside, or extract program information of a specific program from a program information database stored in advance in a storage medium such as the HDD 103. May be.

  The control circuit 101 functionally includes a daily interest information collection unit 111, a daily interest analysis unit 112, a dialogue input / output unit 113, a destination selection unit 114, and a destination output unit 115. Each of these units is realized by software by the CPU in the control circuit 101 executing a predetermined control program stored in the nonvolatile memory 102. The daily interest information collection unit 111 further includes a program viewing information collection unit 121 and a Web search information collection unit 122.

  The control circuit 101 executes two processes: a process of collecting daily interest information of a user (hereinafter referred to as a collection process) and a process of recommending a destination to the user (hereinafter referred to as a recommended process). Hereinafter, these two processes will be described in order.

(Explanation of collection processing)
The collection process is executed by the daily interest information collection unit 111. The daily interest information collection unit 111 updates the daily interest DB 116 in the HDD 103 based on the TV viewing history 201 and the search history 301 read from the portable storage medium 107.

  FIG. 3 is a diagram showing a configuration of the daily interest DB 116. For example, when the user views TV once, one TV viewing history 201 is written in the portable storage medium 107, and one record is added to the daily interest DB 116 by the program viewing information collection unit 121. Each record of the daily interest DB 116 includes a category ID 116a, a genre name 116b, a keyword 116c, and a place name 116d.

  The category ID 116a is an ID representing data that is the basis for creating the record. In the present embodiment, the category ID 116a of the record created from the TV viewing history 201 by the program viewing information collecting unit 121 is “C01”. Similarly, the record created from the search history 301 by the Web search information collection unit 122 has a category ID 116a of “C02”.

  The genre name 116b represents the name of the genre to which this record belongs, and any one of the predetermined genre names is selected. The keyword 116c is a keyword associated with this record. The place name 116d is a place name associated with this record. The “place name” here is, for example, a combination of a prefecture name or a city name representing a specific point, or a specific shop name or facility name. A method for acquiring the genre name 116b, the keyword 116c, and the place name 116d will be described later.

  FIG. 4 is a diagram showing the configuration of the keyword DB 117. The keyword DB 117 is used by the Web search information collection unit 122 to obtain a related genre name from a specific search keyword. The keyword DB 117 stores in advance a large number of predetermined genre names 117a and keyword groups 117b corresponding to the genre names. By using the keyword DB 117, a genre name associated with the keyword can be obtained from a specific keyword.

  FIG. 5 is a flowchart of the collection process performed by the control circuit 101. The collection process of FIG. 4 is executed by the control circuit 101 executing a predetermined control program stored in the nonvolatile memory 102. First, in step S510, the daily interest information collection unit 111 reads various data stored in the portable storage medium 107. In step S520, the daily interest information collection unit 111 determines the type of data read from the portable storage medium 107. If the data read from the portable storage medium 107 is the TV viewing history 201, the collection process proceeds to step S530.

  In step S530, the program viewing information collection unit 121 obtains program information of the program corresponding to the TV viewing history 201 by the program information acquisition device 108. In step S540, the program viewing information collection unit 121 acquires the genre name 116b, the keyword 116c, and the place name 116d to be stored in the daily interest DB 116 from the program information acquired in step S530. For example, when the program information acquisition apparatus 108 acquires program information using the EPG system, the program viewing information collection unit 121 acquires the genre name of the program included in the EPG data as it is as the genre name 116b in the daily interest DB 116. Further, the program viewing information collection unit 121 extracts keywords and place names from the description of the program included in the EPG data by a known technique such as morphological analysis.

  The program viewing information collecting unit 121 uses a place name DB 118 (FIG. 2) stored in the HDD 103 when determining whether or not a particular phrase included in the program description is a place name. That is, the phrase included in the program description is searched from the place name DB 118, and it is determined whether or not the specific phrase is the place name by determining whether or not the place name is stored in the place name DB 118.

  Thereafter, the collection process proceeds to step S570. In step S570, the daily interest information collection unit 111 stores the record including the genre name, keyword, and place name acquired in step S540 in the daily interest DB 116. At this time, the category ID 116a is “C01”.

  On the other hand, if the data read from the portable storage medium 107 is the search history 301 in step S520, the collection process proceeds to step S550. In step S550, the Web search information collection unit 122 searches the keyword group 117b of the keyword DB 117 for a search keyword included in the search history 301. In step S560, the Web search information collection unit 122 determines whether a record including the search keyword in the keyword group 117b has been found. When the corresponding record is not found, the daily interest information collection unit 111 ends the collection process without writing the record in the daily interest DB 116. On the other hand, if a corresponding record is found, the collection process proceeds to step S570.

  In step S570, the daily interest information collection unit 111 applies the genre name 117a in the record of the keyword DB 117 searched in step S550, the search keyword included in the search history 301, and the text included in the searched web page. A record including a place name extracted by applying a known morphological analysis process is stored in the daily interest DB 116. At this time, the category ID 116a is “C02”.

  When multiple types of data are stored in the portable storage medium 107, the daily interest information collection unit 111 repeatedly executes the processing of steps S520 to S570 for each data. Further, in step S540, when a plurality of keywords and place names are extracted from one EPG data, the daily interest information collection unit 111 stores all of them in the daily interest DB 116 as separate records.

  The collection process described above may be executed a plurality of times before the recommended process is executed. Every time it is executed, the daily interest DB 116 stored in the HDD 103 is updated.

(Explanation of recommended processing)
The recommendation process is executed by the daily interest analysis unit 112, the dialogue input / output unit 113, the destination selection unit 114, and the destination output unit 115. First, the daily interest analysis unit 112 reads the daily interest DB 116 from the HDD 103 and analyzes the contents.

  FIG. 6 is a diagram showing an analysis table created by the daily interest analysis unit 112. The daily interest analysis unit 112 analyzes how many records of a specific genre name exist in the daily interest DB 116 and creates an analysis table 131 shown in FIG. That is, the record R1 of the analysis table 131 shown in FIG. 6 indicates that there are 12 records whose genre name 116b is “sports” in the daily interest DB 116. Similarly, the record R2 indicates that there are eight records whose genre name 116b is “information / wide show” in the daily interest DB 116.

  The daily interest analysis unit 112 then extracts the three genre names 131a having the largest number of records 131b from the analysis table 131. Then, for each of these genre names 131a, a maximum of 10 records of a specific genre name 116b are extracted from the daily interest DB 116 by the number corresponding to the ratio of the number of records 131b.

  Hereinafter, the above-described processing by the daily interest analysis unit 112 will be described with a specific example. For example, the top three genre names 131a in the analysis table 131 are “sports”, “information / wide show”, and “music”, and the number of records of the genre name is 12, 8, and 6, respectively. . At this time, the daily interest analysis unit 112 determines, from the daily interest DB 116, a record whose genre name 116b is “sports”, a record “information / wide show”, and a record “music” 12 to 8 respectively. A total of 10 items are extracted at a ratio of 6 to 6.

  That is, since the record whose genre name 116b is “sports” is 10 × 12 / (12 + 8 + 6) = 4.6, five records are extracted. Similarly, three records that are “information / wide show” and two records that are “music” are extracted.

  If there are less than 10 records having these genre names 116b in the daily interest DB 116, the daily interest analysis unit 112 extracts all these records. For example, when there are more than five records whose genre name 116b is “sports”, the daily interest analysis unit 112 may randomly extract five records from the records, or may extract them in the past Records that have not been recorded may be preferentially extracted. Or you may make it extract a record by criteria other than these.

  The daily interest analysis unit 112 outputs the keyword 116c and the place name 116d in the extracted record as analysis results. The analysis result is output to the dialogue input / output unit 113 and the destination selection unit 114. The dialogue input / output unit 113 displays all place names 116d included in the analysis result and a question message for the user on the display device 106. And the input signal showing the specific place name 116d input from the input device 104 by a user's operation is received.

  The question message displayed by the dialogue input / output unit 113 is generated by the dialogue input / output unit 113 based on the keyword 116c and the place name 116d included in the analysis result. This question message is a message for the dialogue input / output unit 113 to narrow down destinations recommended to the user among all the place names 116d included in the analysis result.

  Specifically, the dialogue input / output unit 113 enumerates all place names and keywords included in the analysis result, and generates a question message that prompts the user to input a place name that is desired to be a destination. The user visually recognizes this question message displayed on the display device 106 and then inputs any place name by the input device 104. Thereby, the dialogue input / output unit 113 receives an input signal representing one of the place names.

  Dialog input / output unit 113 outputs the received input signal to destination selection unit 114. The destination selection unit 114 selects the place name represented by the input signal output from the dialogue input / output unit 113 as a place name recommended as the destination. Then, the destination output unit 115 presents the recommended destination to the user by displaying the place name selected by the destination selection unit 114 on the display device 106.

  FIG. 7 is a flowchart of the recommendation process by the control circuit 101. The recommended processing shown in FIG. 7 is executed when the control circuit 101 executes a predetermined control program stored in the nonvolatile memory 102. First, in step S <b> 710, the daily interest analysis unit 112 reads the daily interest DB 116 from the HDD 103. In step S720, the daily interest analysis unit 112 creates the analysis table 131 (FIG. 6) based on the daily interest DB 116 read in step S710. In step S730, the daily interest analysis unit 112 extracts the genre names 131a of the top three records having the largest number of records 131b from the analysis table 131 created in step S720.

  In step S740, the daily interest analysis unit 112 extracts 10 records from the records having the genre name extracted in step S730 out of all the records in the daily interest DB 116. In step S750, the daily interest analysis unit 112 outputs the keyword 116c and the place name 116d of the record extracted in step S740 to the dialogue input / output unit 113 and the destination selection unit 114. In step S760, the dialogue input / output unit 113 displays a question message on the display device. In step S770, the dialogue input / output unit 113 receives an input signal input by the user through the input device 104. In step S780, the destination selection unit 114 selects the place name indicated by the input signal as a destination recommended to the user. In step S790, the destination output unit 115 presents the destination to be recommended to the user by displaying the destination on the display device 106.

According to the recommended destination information distribution system according to the first embodiment described above, the following operational effects can be obtained.
(1) The daily interest information collection unit 111 correlates related place names and genre names based on the user's TV viewing history 201 in the TV terminal 200 and the user's search history 301 in the Web terminal 300, and the daily interest DB 116. Remember me. The daily interest analysis unit 112 analyzes a plurality of place names and genre names stored in the daily interest DB 116, and the dialogue input / output unit 113 notifies the user of information on a destination candidate based on the result of the analysis. The input signal from the input device 104 is received from the user. Then, the destination selection unit 114 selects a destination based on the input signal received by the dialogue input / output unit 113, and the destination output unit 115 presents the selected recommended destination to the user. Since it did in this way, it becomes possible to recommend to the user the movement destination reflecting the user preference which is not limited at the time of driving of a vehicle.

(2) The daily interest analysis unit 112 outputs the keyword 116c as an analysis result together with the place name 116d of the record extracted from the daily interest DB 116. The dialogue input / output unit 113 includes the place name 116d and the keyword 116c in the question message. Since it did in this way, the user can grasp | ascertain what keyword is associated with the notified destination, and can select a destination more suitable for the user.
