When the “detail” in FIG. 3 and FIG. 4 is instructed and operated while the feature information is displayed on the display screen DISP, the detailed information is transmitted from the information server 110 and is stored in the terminal-side area-specific information storage unit 1011C. Once stored, the photographic information as part of the detailed information is displayed on the display screen DISP.

  By the way, the information server 110 provided in the information transmission system 1 of FIG. 1 can be accessed from a mobile mobile terminal device such as the mobile phone 120 or the PC 130 as described in FIG. Since it is not known whether such information is transmitted, the command determining unit 1105 is configured to determine what information has been transmitted. First, how the process is executed according to the content of the command determined by the command determination unit 1105 will be described.

  FIG. 5 is a diagram for explaining processing of the information server 110.

  When some information is transmitted from an external portable mobile terminal and received by the communication unit 1104 when the communication unit 1104 deployed in the information server 110 is in a standby state, the information at the head of the information A command indicating a seed or the like is determined by the command determination unit 1105 in step S501, and processing corresponding to the determined command is started.

  Here, the five types of commands are listed in FIG. For example, if there is a data registration command at the beginning of the information, it is determined that the information after the command is detailed information for data registration, and the process proceeds to step S502 to start the data registration process.

  Thereafter, when it is determined in step S501 that the feature information list acquisition command has been transmitted from the mobile terminal device side, the process proceeds to step S503, where the feature information list acquisition process is started, and the feature information acquisition command is transmitted to the mobile terminal device side. If it is determined that the command has been transmitted from the mobile terminal apparatus, the process proceeds to step S504 to start the feature information acquisition process. If it is determined that the detailed information acquisition command has been transmitted from the mobile terminal device side, the process proceeds to step S505. When the detailed information acquisition process is started and a travel schedule area acquisition command is transmitted, the process proceeds to step S506, and the travel area acquisition process is started.

  FIG. 6 is a flowchart for explaining the details of the data registration process in step S502 of FIG.

  First, the flowchart of FIG. 6 will be described, and then the content of the mesh code will be described.

  Processing executed by the information server 110 will be described with reference to FIG.

  When the process of step S502 in the flow of FIG. 5 is started, the process of the flow of FIG. 6 is started. First, in step S5021, the position information is extracted from the detailed information following the registration command by the information classification unit. In the next step S5022, the mesh code corresponding to the position information (latitude / longitude) in the received detailed information is determined based on the mesh code / latitude / longitude correspondence table held in the map DB 1106. The information DB holds detailed information for each mesh code, and adds detailed information to the mesh code that matches the mesh code determined in S5022. In step S5024 and subsequent steps, the feature information extraction process is started after a certain number (N) of detailed information is accumulated. In step S5024, the count number in the additional posted number holding unit 110A is incremented to count the number of posts for each mesh code so that the number of posts for each mesh code is known. In the next step S5025, it is determined whether or not the number of postings for each mesh code is N or more. If it is determined that the number is less than N, the process proceeds to 'No' and the process of this flow ends.

  If it is determined in step S5025 that the number is N or more, the process proceeds to ‘Yes’. In step S5026, the additional number written in the table in the additional posted number holding unit 110A is reset to zero. Further, in step S5027, the feature creation unit 1102 reads detailed information of the mesh code having the number of additional posts exceeding N, and the process of extracting the feature of the area matching the mesh code is started.

  Before describing the processing of the feature creation unit 1102, the correspondence between the mesh code and the latitude / longitude information described during the processing of FIG. 6 will be described with reference to FIG. 7.

  FIG. 7 is a diagram for explaining the correspondence between mesh codes and latitude and longitude.

  FIG. 7A shows a diagram showing the Japanese archipelago, and FIG. 7B shows a correspondence table between mesh codes and latitude / longitude information. These are in the map DB.

  First, the correspondence between the mesh code and the latitude / longitude will be described with reference to FIG.

  As shown in FIG. 7, the Japanese archipelago is divided by a horizontal and vertical mesh of latitude and longitude. In the map DB 1106, a mesh code (for example, 5439-43-24) is assigned to each area at a predetermined latitude / longitude divided by the mesh as map data. This mesh code allocation may be performed according to the format of national land numerical information, or may be performed according to the created format by creating a unique format.

  Therefore, in the process of step S5021, the information classification unit 1109 extracts position information (latitude / longitude) in the detailed information, and a mesh code corresponding to the position information is determined based on the map data in the map DB 1106, and step S5023. In this processing, the detailed information is classified for each mesh code by the information classification unit, and added to the detailed information held separately for each mesh code in the information DB of the detailed information storage unit 1101. At this time, in step S5024, the information classification unit 1109 increments the count of the number of posts in the additional posted number holding unit 110A.

  That is, the information server 110 includes a communication unit 1104 that is a detailed information receiving unit that receives detailed information to which geographical location information is attached, and a detailed information classification unit that classifies the detailed information received by the communication unit 1104 by area. 1109, and the detailed information storage unit 1101 stores the detailed information classified by the detailed information classification unit 1109.

  Next, the contents of the information DB created in the detailed detail storage unit 1101 and the contents of the table in the additional posted number holding unit 110A will be described with reference to FIG.

  FIG. 8 is a diagram for explaining the contents of the information DB stored in the detailed information storage unit 1101 and the contents of the table in the additional posted number holding unit 110A.

  As shown in FIG. 8A, latitude / longitude, user identifier, posting date, posting time, user evaluation, comment, number of images, and image data are written in the information DB created in the detailed information storage unit 1101. . The database items shown in FIG. 8 (a) may be input via the Internet from the mobile phone 120 and the personal computer 130 in the format according to this, or from a blog already on the Internet, etc. Latitude / longitude information is acquired from the address listed in the blog diary, the user identifier is the blog URL, the posting date is the blog diary registration date, and the user evaluation is scored using Koichi's reputation extraction technology , Comments may be converted to a format such as text information of a blog diary, images may be converted to blog diary image information, and may be input.

  The additional posting number holding unit 110A is provided with the table shown in FIG. 8B. After the mesh code is determined in the process of step S5022, the number of posts for each mesh code is determined in the process of step S5024. When incremented, the incremented count is written in the column for the number of additional posts. In this table, the maximum number N (for example, 10) indicating the upper limit of the number of information for starting feature extraction is also written.

  Next, the contents of the information DB will be described.

  FIG. 9 is a diagram for explaining the contents of the information DB.

  Since the feature creation unit 1102 extracts features based on the information DB in the detailed information storage unit 1101, the mesh DB and the feature information are linked in the information DB in the detailed information storage unit 1101 as shown in FIG. A third table that associates the first correspondence table, the second table in which posted information from which feature information is mainly extracted is written, and the image file name having the posted information and image information that is a part of the posted information. Are stored.

  Therefore, when data in the information DB is read from the detailed information storage unit 1101 by the feature creation unit 1102, first, the first correspondence table is referred to, and a table that is feature information corresponding to the mesh code, for example, DATA-5438- After 23-23 is read, the third table is referenced as necessary to read the image information. In the table 3, an identifier to which the ID given in the table 2 is added is added as an index for reading image information in the image table.

  FIG. 10 is a diagram illustrating the configuration of the feature DB.

  Features are extracted by the feature creation unit and a feature DB shown in the figure is created.

  A method for creating the characteristics of each item will be described later, but the contents of the items will be briefly described.

  There is a mesh code as the top item, and for each mesh code, the number of posts based on the post data in the detailed DB is extracted and registered as features of usual post count, time post count change, and location post count change. ing.

  As for the number of users, similar to the number of posts, the number of normal users, the change in the number of time users, and the change in the number of place users are extracted and registered as features based on the post data.

  Furthermore, the reputation of the user is extracted and registered as a feature based on the user evaluation in the posted data.

  When creating such a feature DB, if feature information and detailed information are distinguished and stored in the information DB, feature creation by the feature creation unit 1002 is easy.

  When the information DB in the detailed information storage unit 1101 is configured in this way, the feature creation unit 1002 reads feature information and detailed information separately from the information DB in the detailed information storage unit 1001 according to the mesh code. Can do.

  Here, the details of the feature creation processing executed in step S5027 will be described with reference to FIG. 11, returning to the processing in step S5027 in FIG. The feature creation process shown in FIG. 11 is performed by the feature creation unit 1002 shown in FIG. FIG. 2 shows that four detection units (the number of posts, the number of users, reputation, and keywords) are provided in the feature creation unit 1002 and four types of feature extraction are performed.

  FIG. 11 is a flowchart showing details of the feature creation processing in step S5027 of FIG.

  First, post information (see FIG. 9) matching the mesh code is read from the information DB in the detailed information storage unit 1101 in the process of step S50271. In the process of the next step S50272, frequent keywords are extracted from comments (see FIG. 9) in the posted information, and up to M feature information consisting of the extracted keywords is extracted in the order of frequent keywords, and stored in the feature information storage unit. A feature DB is created.

  In the next step S50273, a feature relating to the number of posts is created. Subsequently, in a step S50274, a feature relating to the number of users is created. In step S50275, a feature relating to user evaluation is extracted, and a feature DB is stored in the feature information storage unit. Created.

  Here, the keyword search is omitted because it is easy, and what characteristics are created from the number of posts by the process of step S50273 will be described.

  In this embodiment, a feature DB is created by first performing a process of extracting whether or not detailed information has increased or decreased over time as a feature, and then performing a process of extracting differences from adjacent areas as feature information. The processing contents will be described.

  FIG. 12 is a flowchart illustrating details of step S50273 executed by the feature creation unit 1102.

  In step S502731, the average number of posts A per time interval ΔT over the past, for example, several months is obtained for the number of posts. In the next step S502732, the average number of posts B per time interval ΔT for the past 7 days is obtained. In the next step S502733, B and A are compared.

  If it is determined in step S502733 that B is smaller than A × 0.9, it is determined in step S502734 that the number of recent posts is small, and B is between A × 0.9 and A × 1.1. If it is determined that there is, the number of posts is determined not to change in step S502735, and if it is determined that B is greater than A × 1.1, it is determined that the number of recent posts is large in step S502737. Here, for example, based on the determination in step S502736, information such as whether the number of posts has recently been large or small is registered in the feature DB as feature information.

  Next, the process proceeds to step S502737, and mesh codes of eight surrounding areas are acquired in step S502737. The detailed information of the surrounding eight areas is read from the mesh code, the average number of posts in each area is obtained, and the average value C of the average number of posts in the eight areas is obtained.

  In the next step S502740, it is determined whether the average value C is smaller than A × 0.9, between 0.9 × A and 1.1 × A, or larger than 1.1 × A. Is done. If it is determined in step S502740 that the average value C is smaller than A × 0.9, the process proceeds to step S502741 and it is determined in step S502274 that the number of posts is smaller than the surroundings, and in step S502740, 0.9 × A to 1.1 × A. If it is determined that the number of posts has not changed, the process proceeds to step S502642. If it is determined in step S502740 that the number of posts is greater than 1.1 × A, the process proceeds to step S502743 and the process proceeds to step S502743. It is determined that there are more posts than the surroundings. When the determination results of steps S502737 and S502744 are registered in the feature DB in the feature storage unit 1103, the process of this flow ends.

  When the process of this flow is executed, it can be determined whether or not the area is a place of interest to the user based on the number of posts per area or the number of posts. For example, in step S502743, there are more than the surroundings. If it is determined that there is a lot of recent topics in step S502736, it is considered that there is a lot of topics or a place where the user is highly interested. Therefore, such information is notified to the user as feature information. In FIGS. 3 and 4, the information is indicated by arrows.

  Further, in the process of step S50274 in the flow of FIG. 11, the same process as the process of FIG. 12 is executed for the number of users, and in the process of step S50275 of FIG. 11, the process similar to the process of FIG. Executed.

  That is, the feature information creation unit of the present embodiment creates feature information consisting of features for each area and temporal changes of the features from the detailed information referred to in the present invention, and from the detailed information, This means that feature information consisting of the features for each area and the differences between the features for each area and the features of adjacent areas adjacent to each area is created.

  Here, in this embodiment, since the information DB can be created in the information storage unit by terminal area also on the mobile terminal device side, the configuration of the DB created in the information storage unit by terminal area will be described. To do.

  FIG. 13 is a diagram for explaining the information DB.

  Since the feature DB and the information DB are separate on the center side, the database shown in FIG. 9 is used. However, since there is only one storage unit on the terminal device side, it is preferable to make it as shown in FIG.

  Since the feature information is created by the information server 110 and the feature information is acquired by the reception control unit 101B, the feature information is added when creating the correspondence table between the mesh code and the detailed data table name as shown in FIG. Has been done. With this configuration, it is possible to read out only feature information from the table serving as the information DB on the mobile terminal side, which constitutes the database when moving, and a data table representing post information as detailed information related to the feature information The image information can be read out from the image table by referring to the file name in the data table.

  Finally, how the command described in the flow of FIG. 5 is transmitted from the mobile terminal device to the information server when the mobile terminal device moves will be described.

  FIG. 14 is a process executed by the information reception control unit 101B on the mobile terminal device 100 side when transmitting the scheduled travel area acquisition command, the feature information acquisition command, and the detailed information acquisition command of FIG. 5 to the information server 110. It is a flowchart which shows the procedure of.

  First, in step S1401, it is determined whether or not the next area has been entered. This process is performed by comparing latitude / longitude information indicating the range of the mesh code acquired by the planned travel area acquisition unit described later with the latitude / longitude acquired by the current position acquisition unit 101A. If the latitude / longitude acquired by the current position acquisition unit 101A is within the latitude / longitude indicating the range of the mesh code acquired by the planned travel area acquisition unit, it is determined that the next area has been entered, and the processing to the 'Yes' side The area that entered in step S1402 is changed from the area before entry to the current area. In the next step S1403, it is determined whether or not information on the previous area is being acquired. If it is determined that the information is not being acquired, the process proceeds to 'No'. If it is determined that the information is being acquired, the process proceeds to step S1404. After the cancellation, the process proceeds to step S1405.

  In step S1405, the feature information of the current area is acquired from the information server 110, and the display shown in the upper right of FIG. 4 is performed on the display screen DISP. In the next step S1406, the information server 110 acquires which is the next scheduled travel area of the current area.

  In the next step S1407, it is determined whether or not there has been a detailed information acquisition operation instruction from the user. If it is determined that the operation has been performed, the process proceeds to “Yes” and detailed information is acquired in step S1408, and the upper right of FIG. Is switched to the lower right screen. If it is determined in step S1407 that there is no detailed information acquisition request from the user, this flow processing ends.

  That is, in this example, when the mobile terminal device enters a new area, the information reception control unit 101B causes the communication unit 102 to make a transmission request for the feature information of the entered area to the information server 110. In addition, a process for receiving feature information for each approach area is performed, and a transmission request for information corresponding to the next area ahead of the route of the mobile terminal device (mesh code and latitude / longitude information indicating the range of the mesh code) is also made. It is

  In this way, the upper right display in FIG. 4 is displayed on the display screen DISP, and when the detailed information display instruction operation is received from the user, the detailed information acquired in the process of step S1408 is displayed on the display screen. That is, when the process of this flow is performed, the display is performed as shown in FIG. 4, and the display screen is switched according to the instruction operation.

  Details of the next travel area acquisition process in step S1406 of FIG. 14 will be described here.

  In this travel area acquisition process, after the current position and the traveling direction are detected by the information reception control unit 101B, a travel planned area acquisition command and information indicating the current position and the traveling direction are transmitted to the information server 110. Be started by.

  Here, the processing of the information server 110 will also be described later so that the correspondence with the information server can be understood.

  FIG. 15 is a flowchart showing processing on the mobile terminal side and the information server side regarding travel area acquisition. The terminal-side flow processing is executed by the information reception control unit 101B.

  In step S14061, the current position is acquired from the current position information acquisition unit 101A. When two pieces of information on the current position are acquired at predetermined processing intervals by the timer value in the information reception control unit 101B, the traveling direction is acquired in the next step S14062. If the terminal has a gyro sensor, the traveling direction acquisition process may be performed using the gyro sensor. In step S14063, it is determined whether or not the information server 110 is connected. If it is determined in step S14063 that the information server 110 is connected, the process proceeds to “Yes”. In step S14064, the scheduled travel area acquisition command and the current position are determined. The traveling direction is transmitted to the information server 110.

  The mesh code representing the next travel area and the latitude / longitude information in the range indicated by the mesh code are transmitted from the information server 110 and received by the reception control unit 101B, and this is used as the next travel area information to the travel planned area holding unit. Retained.

  If it is determined in step S14063 that the information server 110 is not connected, the process from step S14064 to step S14066 is executed if the connection is attempted in step S14067 and if successful, an error message is displayed on the display screen DISP in step S14068. And output from the audio output unit as audio.

  The information server 110 receives the process of step S14065 and executes the scheduled travel area acquisition process S506 in FIG. The mesh code of one or more areas where the car is supposed to enter from the current position and the traveling direction transmitted from the mobile terminal device 100 in step S5061 and the latitude / longitude information of the range indicated by the mesh code are the map data in the map DB. Is detected based on Then, in step S5062, the information server 110 transmits these pieces of information to the mobile terminal device 100.

  In this way, information on the scheduled travel area is acquired.

  Finally, the feature information acquisition process performed in step S1405 of FIG. 14 and the detailed information acquisition process of step S1408 will be described with reference to FIGS. The processing in FIGS. 16 and 17 is processing on the mobile terminal device side corresponding to the feature information acquisition processing in step S504 and the detailed information acquisition processing in step S505 in FIG. That is, a feature information acquisition command or a detailed information acquisition command is transmitted from the mobile terminal device side to the information server.

  FIG. 16 is a flowchart showing a procedure of feature information acquisition processing executed by the information reception control unit 101B, and FIG. 17 is a flowchart showing a procedure of detailed information acquisition processing executed by the information reception control unit 101B. is there.

  First, in step 14051, it is determined whether or not the information server 110 is connected. If it is determined in step S14051 that the connection is established, the process proceeds to 'Yes', and a mesh code and a feature acquisition command are transmitted to the information server in step S14052. If feature information is transmitted from the information server 110 in step S14053, the feature information is received, and it is determined in the next step S14054 whether there is feature information. If it is determined that there is no feature information, the process of this flow ends. If it is determined in step S14054 that feature information exists, the feature information is downloaded from the information server side and stored in the information DB on the terminal side. When the stored contents of the terminal-side area-specific information storage unit are updated in the next step S14055, the feature information is displayed on the display screen DISP or the audio information is output in step S14056.

  If it is determined in step S14051 that the information server 110 is not connected, the process proceeds to the “No” side, and a connection is attempted in step S14057. If the connection is successful in step S14057, the processing from step S14052 to step S14056 is executed. If the connection fails in step S14057, an error message is displayed on the display screen DISP, and in the next step S14069, it is determined whether or not there is feature information matching the mesh code in the terminal-side area information holding unit. If it is determined that the feature information is present, the feature information is displayed on the display screen in step S14056. If it is determined that the feature information is not present, the processing of this flow is terminated.

  When the detailed information acquisition process in step S1408 is started, it is first determined in step S14081 whether the information server 110 has been connected. If it is determined in step S14081 that the connection is established, the process proceeds to the 'Yes' side, and a mesh code and a detailed information list acquisition command are transmitted to the information server 110 in step S14082. In step S14083, a detailed information list is received from the information server. The detailed information list referred to here is the ID in FIG. 9B. In step S14084 and subsequent steps, it is checked whether the detailed information matching the ID (information in FIGS. 9B and 9C) is in the terminal-side area information storage unit 1011C. Come. In step S14084, it is determined whether IDs to be checked still remain. If there is an ID to be checked (the list is not finished), one ID is extracted from the received ID list from the “No” side to step S14085, and in step S14086, the terminal-side area-specific information storage unit 1011C It is determined whether there is detailed information having the same ID in the information DB. If it is determined that there is detailed information, the detailed information is displayed on the display screen in step S14090, and the process returns to step S14084.

  If “None” is determined in step S14086, an ID and detailed information acquisition command is transmitted to the information server 110 in step S14087, detailed information matching the ID is received and received in step S14088, and the terminal side in step S14089. Detailed information is stored in the area-specific information DB. In step S14090, the detailed information is displayed on the display screen, and the process returns to step S14084. If it is determined in step S14084 that there are no more IDs to be checked (list ends), the process proceeds to the “Yes” side and ends.

  If it is determined in step S14081 that the information server 110 is not connected, the process from step S14083 is executed if the connection is attempted and successful in step S14091. If it is determined in step S14091 that the connection has failed, an error message is output from the display screen or the speaker in step S14092. In step S14813, it is determined whether there is detailed information that matches the mesh code in the terminal area information DB. If it is determined, the detailed information is displayed on the display screen or output by voice and this flow is displayed. Processing is finished. If it is determined “NO” in step S14093, the processing of this flow is immediately finished.

  FIG. 14 shows a process when the mobile terminal is moving, and it may be started from the information acquisition process of the current area at the start of movement.

  In this way, according to the command transmitted from the mobile mobile terminal device to the information server, processing is performed on the information server side, and the feature information and the detailed information are transmitted separately. Since the information is divided and transmitted to the mobile terminal device, a ripple effect that the memory capacity of the mobile terminal device is reduced can be obtained.
