  The task model storage unit 21 is a database in which behavior information that identifies user behavior is hierarchized and stored in association with the category of the behavior and the executable conditions. Specifically, user behavior information is managed as a “task” and is modeled as a task model. Note that the task model storage unit 21 does not specify the behavior of each individual user, but models the behavior that the user can take and creates a database. Specifically, the task model storage unit 21 holds a task model management table (task model management database) 21a and a task attribute management table (task attribute management database) 21b, and stores data in these tables. Retain information by storing.

  The task model management table 21a holds each task constituting the task model in association with category information indicating the category of the task. FIG. 4 is a diagram illustrating an example of the task model management table 21a. As shown in FIG. 4, in the task model management table 21a, “task ID”, “task name”, “parent task ID”, “plan”, “task type”, and “assumed execution time” are recorded as one record. Data is stored in association.

  “Task ID” is an ID for uniquely identifying a task, and is composed of a character string of several characters. The “task name” is information indicating specific contents of a task such as “determine a sightseeing spot” or “reserve a rental car”.

  The “parent task ID” is a task ID that identifies the parent task of the task, and is information that forms a hierarchical structure of the task model. A parent task is a higher-order task. From the perspective of the parent task, the task becomes a subtask. For example, tasks such as “check ski information” and “check hot spring information” refer to “1002” as the “parent task ID” to achieve the reference task “obtain tourist information”. Indicates that this is a subtask. Note that this information is not stored when there is no parent task.

The schedule information registration process by the mobile communication terminal 14 will be described later with reference to FIG. Further, the history request receiving unit 24 receives history information such as the task selected by the user and the timing when the user browsed the distribution information from the mobile communication terminal 14.

  The schedule related task selection unit 25 refers to the task model management table 21 a and selects a task associated with the category information included in the schedule information received by the history request reception unit 24. Specifically, the schedule related task selection unit 25 refers to the “schedule” column of the task model management table 21a and selects the same task as the “schedule category” included in the schedule information. For example, in the example of FIG. 4, when the category of the schedule information is “travel”, all tasks are selected.

  Furthermore, the schedule related task selection unit 25 refers to the task selection history management table 22b and corresponds to the “user ID” received by the history request reception unit 24 for each of the tasks selected from the task model management table 21a. The selection history may be acquired, and the order in which the task selected from the task model management table 21a is presented to the user may be rearranged based on the selection history. Specifically, the schedule related task selection unit 25 checks whether or not the task selected from the task model management table 21a is held in the task selection history management table 22b, and is held in the task selection history management table 22b. In this case, the task is set to be displayed at the top.

  For example, it is assumed that a list of tasks related to the category “business trip” of the schedule information is displayed on the mobile communication terminal in the order shown in FIG. 10A by default. 10B, the user selects the “Shinkansen” task 1004 from the “Traffic ticket reservation” task 1001, and selects the “Train” task 1005 from the “Traffic information acquisition” task 1002. When the “business trip settlement” task 1003 is selected, these selection histories are held in the task selection history management table 22b. Then, when “business trip” is selected in the schedule information category next time based on this selection history, “Shinkansen” task 1004 in “reservation ticket reservation” task 1001 as shown in FIG. Are sorted higher, and “acquisition of traffic information” task 1002 and “business trip settlement” task 1003 are rearranged higher than “hotel reservation” task and “transfer guidance” task. In addition, the “train” task 1005 is rearranged in the “traffic information acquisition” task 1002.

  The schedule related task execution date and time estimation unit 26 sets the date and time when the task selected from the task model management table 21a by the schedule related task selection unit 25 is executed. Specifically, the schedule related task execution date and time estimation unit 26 refers to the task selection history management table 22b for each task selected by the schedule related task selection unit 25 and acquires the selection history of the task. Then, the number of days registered in the “days until schedule” field (see FIG. 7) of the selection history is subtracted from the “scheduled date” of the schedule information received by the history request receiving unit 24. Set as the execution date and time. When the task selection history management table 22b does not hold the selection history of the task, a predetermined default date and time stored in advance in the schedule related task execution date and time estimation unit 26 is set.

  When a user registers a schedule of the same category a plurality of times in the past and the set date and time are different from each other, the task selection history management table 22b includes a plurality of different “days until the schedule” for the same user and the same task. Will be stored. In this case, the schedule related task selection unit 25 and the schedule related task execution date and time estimation unit 26 determine a schedule related task to be presented by reflecting a past history for a certain period. For example, the list is rearranged in the order of the specified frequency. The default date and time is calculated by calculating the average number of days until the target schedule (such as “4 days ago” if the same task has been registered “3 days ago” and “5 days ago”). Determine the value. The method as described above is merely an example, and other methods may be used.

  The task type determination unit 27 determines the type of the task selected from the task model management table 21a by the schedule related task selection unit 25. Specifically, the task type determination unit 27 acquires the data in the “task type” column (see FIG. 4) of the task model management table 21a for each of the tasks.

  In addition, the schedule related task selection unit 25 acquires, from the task selection history management table 22b, a task selection history that is the same as the task type based on the task type determined by the task type determination unit 27. Based on the selection history, the order of presenting the task selected from the task model management table 21a to the user may be rearranged.

  Referring to FIG. 10 again, the user who performed the process (FIGS. 10A to 10C) for selecting the task related to the above “business trip” registers the schedule of “travel” as another schedule, Further, when the user registers a “travel” schedule for the first time, a list of tasks related to the category “travel” of the schedule information is displayed in the order shown in FIG. 10D by default. The schedule related task selection unit 25 first checks whether or not there is a selection history of a “travel” related task from the history management table, but no history is recorded in this example. Next, the task type determination unit 27 reads the “task type” of the related task “travel” from the task model management table 21a, and reads all the histories of the task of the same “task type” from the task selection history management table 22b. Determine the priority according to the task type. In the example of FIG. 10, the task types of the “Shinkansen” task 1008 in the “Traffic ticket reservation” task 1006 and the “Train” task 1009 in the “Traffic information acquisition” task 1007 are shown in FIG. "Reservation" and "Traffic information acquisition" are defined. These task types include the “Shinkansen” task 1004 in the “Reservation ticket reservation” task and the “Train” task 1005 in the “Traffic information acquisition” task registered in the past for the “business trip” schedule. Since these are the same, refer to these histories. As a result, even when the user registers a “travel” schedule for the first time, the “traffic ticket reservation” task 1006 and the “traffic information acquisition” task 1007 are preferentially presented as shown in FIG. Is done. The past history is also reflected in the default execution time when these schedules are registered.

  The task profile matching unit 28 filters the tasks selected by the schedule related task selection unit 25 based on profile information indicating user attributes. The user profile information is read from the profile management table 22a. Further, the execution conditions of each task of the task model are read from the task attribute management table 21b. The task profile collating unit 28 collates the two pieces of read information, and deletes tasks that do not match the conditions from the presentation candidates.

  FIG. 11 is a diagram showing an example of a schedule related task displayed on the mobile communication terminal 14 based on the user profile information. FIG. 11A shows an example of a candidate list of schedule-related tasks presented to a user having the attributes 1101 of “female”, “25 years old”, “resident in Kanagawa”, and “unmarried”. FIG. 11 (b) is presented to a user having attributes 1102 of “male”, “40 years old”, “resident in Tokyo”, “car ownership”, “driving license”, “married”, “two children”. It is an example of a candidate list of scheduled related tasks to be performed. As shown in FIG. 11, the schedule related tasks are hierarchically displayed with the task having no parent task ID as the highest level based on the “task ID” and “parent task ID” (see FIG. 4) of each task. The

  In the example of FIG. 11, first, a list 1103 of the highest schedule related tasks related to the “travel” category is displayed. This top-level task list 1103 is the same between the illustrated users (a) and (b). Here, for example, when the “recommended sightseeing information” task 1104 is selected from the task list 1103, the “recommended sightseeing information” selected by the task profile matching unit 28 according to the user attributes 1101 and 1102. “A list of tasks having the task 1104 as a parent task is newly displayed. For example, for a user (a) having an attribute 1101 such as “female” and “25 years old”, a task list 1105 such as “skiing and snowboarding” and “eating” is presented. In the case of the user (b) having attributes 1102 such as “male”, “40 years old”, “car ownership”, a task list 1106 such as “hot spring tour”, “autumn leaf tour”, “drive” is presented.

  The schedule related task transmission unit 29 transmits the task selected by the schedule related task selection unit 25 to the mobile communication terminal 14 as a candidate list of schedule related tasks.

  When the distribution information acquisition unit 30 receives the schedule related task selected by the user from the schedule related task candidate list sent from the schedule related task transmission unit 29 to the mobile communication terminal 14, the distribution information acquisition unit 30 refers to the distribution information management table 23a. The distribution information associated with the schedule related task is acquired.

  The optimum information delivery date estimation unit 31 refers to the delivery information browsing history management table 22c, acquires the viewing history of the delivery information transmitted to the mobile communication terminal 14 by the delivery information transmitting unit 33, and based on this viewing history. The timing for transmitting distribution information is obtained. Specifically, the optimal information distribution date estimation unit 31 acquires the browsing history of the distribution information for each of the distribution information acquired by the distribution information acquisition unit 30 with reference to the distribution information browsing history management table 22c. Then, the optimal information distribution date and time is obtained by subtracting the number of days registered in the “browsing time” column (see FIG. 8) of the browsing history from the execution date and time of the schedule related task associated with the distribution information. Set.

  In the example of FIG. 8, the distribution information of “sightseeing information guide” associated with a task defined with “place determination” as the task type is the optimal timing at which “3 days before” the scheduled date and time of this task distributes the information. The date and time obtained by subtracting 3 days from the scheduled date and time of the task is set as the optimum information delivery date and time. In addition, in the distribution information browsing history management table 22c, when the history of browsing the same distribution information “two days ago” is also held at the same time, the optimal information distribution is considered in consideration of all past histories within a certain period. It is determined that the date is. The simplest implementation is to find a simple average, but you can use another method. The determination that “the user has viewed” is determined in advance, for example, when the user clicks on the header information displayed in the telop on the screen of the mobile communication terminal 14 and browses the detailed information. .

  The distribution information category selection unit 32 assigns a weighted priority for each piece of distribution information acquired by the distribution information acquisition unit 30 with the timing of distributing the distribution information obtained by the optimum information distribution date and time estimation unit 31 as a center. The distribution information to be distributed to the mobile communication terminal 14 is selected based on this priority. For example, especially when a plurality of schedules are registered by a user, a plurality of distribution information may be distributed on the same day, no information may be distributed, or the amount of information distribution may vary depending on the day. It is done. In the present embodiment, it is assumed that the distribution information is displayed in a specific area on the screen of the mobile communication terminal 14 like a telop, and it is desirable that the distribution information is distributed to the mobile communication terminal 14 at a certain number every day.

  Specifically, the distribution information category selection unit 32 determines the weight of individual distribution information at a specific date and time based on the difference in date and time from the optimal distribution date and time, and determines the information category to be distributed at the specific date and time and the ratio thereof. decide. Here, in order to simplify the explanation, it is assumed that the weight of the optimal delivery date is 1, and the weight is linearly decreased by 0.1 due to the difference per day. In other words, if there is a difference of 10 days, the weight becomes 0 and distribution is not performed. For example, the distribution information on July 8 has a weight of 0.9 because the “hotel reservation” information whose optimal distribution date is July 9 is one day different. In addition, “vacant room information” in which July 14 is the optimal delivery date has a weight of 0.4 because there is a difference of 6 days. Accordingly, the information distributed on July 8 has a priority and information amount of “hotel reservation” and “vacant room information” at a ratio of 0.9: 0.4.

  The distribution information transmitting unit 33 performs the distribution information selected by the distribution information acquiring unit 30 at a timing corresponding to the time information (“scheduled date”) included in the schedule information received by the history request receiving unit 24. 14 to send. Here, the “timing according to time information” is specifically the distribution date determined by the priority set by the distribution information category selection unit 32 and the distribution information amount of each day.

  This completes the description of the function of the information distribution server 12.

  Next, functions of the mobile communication terminal 14 will be described. As shown in FIG. 1, the mobile communication terminal 14 includes a schedule input unit 40, a schedule management unit 42, a schedule display control unit 44, a TODO list management unit 46, a TODO list display control unit 48, and input information transmission. A section (schedule information transmission means, behavior information transmission means) 50, a schedule related task input section (schedule related task input means) 52, and a distribution information display control section (distribution information display control means) 54.

  The schedule input unit 40 is a means for receiving input of information (schedule information) related to a scheduled action performed by the user of the mobile communication terminal 14. FIG. 12A is a diagram illustrating an example of a display screen of the mobile communication terminal 14 for schedule information input processing by the schedule input unit 40. The schedule information input by the user includes a “schedule category” indicating schedule category information and a “schedule date and time” indicating schedule time information. Further, the schedule information may include a “schedule name” indicating the name of the schedule. The “planned category” is designated by the user from a pull-down menu, for example. The contents of this pull-down menu are set according to a format registered in advance by the user or a format received from the information distribution server 12. In FIG. 12A, “Travel” is designated as the scheduled category by the user, “July 26-27, 2007” is entered as the scheduled date and time, and the “Register” button on the screen is pressed. Thus, the schedule information is registered in the mobile communication terminal 14.

  The schedule management unit 42 is means for storing the user's schedule information registered by the schedule input unit 40. The registered schedule information is sent to the input information transmission unit 50 for transmission to the information distribution server 12.

  The schedule display control unit 44 is a means for registering and displaying user schedule information stored in the schedule management unit 42 in a calendar function such as scheduler software. FIG. 12B is a diagram illustrating an example of a calendar function in which schedule information is registered by the schedule display control unit 44. In FIG. 12B, schedule information (category: travel, date and time: July 26 to 27, 2007) registered from the schedule input unit 40 described above is displayed on the July 26 to 27 part of the calendar. It is displayed. When the user wants to register a new schedule or edit a registered schedule, the user can press the “Register” or “Edit” button on the screen to display the schedule input screen shown in FIG. Switch to enter new information on this screen.

  The input information transmission unit 50 receives the schedule information received from the schedule management unit 42 and the TODO list management unit 46 together with “user ID” which is an identifier set in advance to identify the user of the mobile communication terminal 14. It is means for transmitting to the distribution server 12.

  The schedule related task input unit 52 receives a candidate list of schedule related tasks associated with the schedule information transmitted to the information distribution server 12 by the input information transmission unit 50 from the information distribution server 12, and presents this candidate list to the user. Thus, it is means for prompting the user to register a desired task as a schedule related task. FIG. 13A is a diagram illustrating an example of a display screen of the mobile communication terminal 14 for a schedule related task selection process by the schedule related task input unit 52. In FIG. 13A, following FIG. 12, a list of tasks associated with “travel” when the schedule category of “travel” is registered by the schedule input unit 40 is “task ID” and “ Based on the “parent task ID” (see FIG. 4), it is displayed hierarchically on the screen.

  When a “Traffic Ticket Reservation-Shinkansen” task 1301 is selected from these lists and the “Register” button at the bottom of the screen is pressed, the screen is switched to a registration confirmation screen as shown in FIG. In this registration confirmation screen, when the scheduled date and time for executing the selected task is input and the “Register” button is pressed, this task is registered as a schedule related task. The schedule related task input unit 52 can register a plurality of schedule related tasks by repeating such a procedure.

  The task registered by the schedule related task input unit 52 is sent to and saved in the schedule management unit 42, and further sent to the schedule display control unit 44, together with the previously registered schedule information, such as scheduler software. Registered and displayed in the calendar function. FIG. 14 is a diagram illustrating an example of a calendar function in which schedule information and schedule-related tasks are registered by the schedule display control unit 44. It is also possible to register a task without specifying the scheduled date and time on the registration confirmation screen shown in FIG. 13B. In this case, the schedule-related task is stored in the TODO list management unit 46 and started from the scheduler software. It is displayed on the possible to-do list display control unit 48. With this configuration, even when a specific date and time has not been determined, it is possible to prevent the user from forgetting to register a schedule related task, and to reduce the burden of the user inputting detailed schedule information.

  The schedule related task registered by the schedule related task input unit 52 is transmitted from the schedule management unit 42 or the TODO list management unit 46 to the information distribution server 12 via the input information transmission unit 50. In response to this, the distribution information associated with each of the registered schedule-related tasks is transmitted from the information distribution server 12 to the mobile communication terminal 14 at an appropriately set distribution timing.

  When the distribution information is received from the information distribution server 12, the distribution information display control unit 54 displays the distribution information on the screen of the mobile communication terminal 14 by means such as telop and presents it to the user. FIG. 15 is a diagram illustrating an example of a screen of the mobile communication terminal 14 on which distribution information is displayed. As shown in FIG. 15, for example, “place determination” task 1501 set on July 12th to 13th is refreshed according to the set date and time of this task 1501. Information useful for the “place determination” task “Kinugawa Onsen.” Is distributed from the information distribution server 12 to the mobile communication terminal 14 and displayed on the telop display unit 1502 on the screen.

  Subsequently, processing executed in the information distribution system 10 of the present embodiment will be described using the flowcharts of FIGS.

  In the information distribution system 10, schedule information indicating an action scheduled to be performed by the user from the mobile communication terminal 14 to the information distribution server 12 before information distribution is performed, and a schedule related task associated with the schedule information. Processing to register is performed. This registration process performed in the mobile communication terminal 14 will be described with reference to the flowchart of FIG.

  First, schedule information input by the user of the mobile communication terminal 14 by the schedule input unit 40 is transmitted to the information distribution server 12 via the input information transmission unit 50 (S101). Specifically, the “schedule category” and “schedule date / time” related to the schedule input by the user and the “user ID” of the mobile communication terminal 14 are transmitted to the information distribution server 12. The schedule information is registered by the user using a registration screen of the mobile communication terminal 14 as shown in FIG.

  In response to the reception of the schedule information, the information distribution server 12 selects a schedule related task candidate list associated with the schedule information and transmits it to the mobile communication terminal 14 that has transmitted the schedule information. The process of selecting the schedule related task candidate list will be described later with reference to FIG.

  Subsequently, the mobile communication terminal 14 receives a candidate list of scheduled related tasks from the scheduled related task transmission unit 29 of the information distribution server 12 (S102), and this candidate list is presented to the user. The candidate list of schedule related tasks is displayed on the screen of the mobile communication terminal 14, for example, as shown in FIG.

  The schedule related task input unit 52 confirms whether or not the user has selected a task from the schedule related task candidate list presented on the screen of the mobile communication terminal 14 (S103). If the user has selected a task, the process proceeds to step S104 and the process is continued. If the user has not selected a task, the process ends without registering a new task.

  If it is determined in step S103 that the user has selected a task, the schedule related task input unit 52 continues to check whether or not the date and time for executing the selected task has been specified by the user (S104). ). If the date and time of the task is specified, the task is registered in the schedule management unit 42, and the task is displayed on the calendar function of the scheduler, for example, as shown in FIG. 14 (S105). If the date and time of the task is not specified, the task is registered in the TODO list management unit 52, and the task is displayed in the TODO list (S106).

  Subsequently, the schedule-related task input unit 52 confirms whether or not the user registers another task as the schedule-related task (S107). If another task is registered, the process returns to step S104, and the new schedule-related task registration process is continued. When not registering another task, the task selected by the user is transmitted to the information distribution server 12 by the input information transmitting unit 50 as a schedule related task (S108), and the process is terminated.

  The above is the process of registering the schedule information indicating the action scheduled to be performed by the user and the schedule related task associated with the schedule information, which is executed in the mobile communication terminal 14.

  Subsequently, a process executed in the information distribution server 12 for selecting a candidate list of schedule related tasks associated with the schedule information based on the schedule information of the user will be described with reference to the flowchart of FIG. This process is executed by the information distribution server 12 between step S101 and step S102 in the process of registering the schedule related task by the mobile communication terminal 14 shown in FIG.

  First, the history request receiving unit 24 receives the user's schedule information (scheduled category, scheduled date and time) and the user ID of the mobile communication terminal 14 from the mobile communication terminal 14 (schedule information receiving step: S201). Then, the schedule-related task selection unit 25 refers to the task model management table 21a based on the schedule category included in the schedule information received by the history request reception unit 24, and selects a task corresponding to the schedule category ( Schedule-related task selection step: S202).

  Subsequently, the task profile matching unit 28 refers to the profile management table 22a based on the user ID of the mobile communication terminal received by the history request receiving unit 24, and whether or not the profile information corresponding to the user ID is held. Is confirmed (S203). If the profile information corresponding to the user ID is not held in the profile management table 22a, the process proceeds to step S206, bypassing steps S204 to S205.

  If the profile information corresponding to the user ID is stored in the profile management table 22a in step S203, the task profile matching unit 28 reads the user profile information corresponding to the user ID from the profile management table 22a. (S204). In addition, the task profile matching unit 28 refers to the task attribute management table 21b, and also reads user attribute conditions (selectable conditions) that can be selected by each of the tasks selected by the schedule related task selection unit 25 in step S202. .

  Then, the task profile collating unit 28 collates the user profile information with the task selectable condition, and does not match the selectable condition based on the user profile information among the tasks selected by the schedule related task selecting unit 25. The task is deleted, and a schedule related task candidate list (presentation task list) to be presented to the user of the mobile communication terminal 14 is created (S205).

  Subsequently, the schedule related task selection unit 25 refers to the task selection history management table 22b and reads the selection history of tasks included in the presented task list (S206). The schedule related task selection unit 25 determines the priority of tasks included in the presented task list based on the selection history (S207), and rearranges the presented task list according to the priority. Specifically, among the tasks included in the presented task list, the presented task list is rearranged so that a task that has been selected by the user in the past is placed higher.

  Moreover, the scheduled related task execution date and time estimation unit 26 determines the execution date and time of the task based on the selection history for the tasks held in the task selection history management table 22b among the tasks included in the presented task list ( S208). Specifically, for each task in the presented task list, the data in the “days until schedule” column of the task selection history management table 22b is referred to, and this data is set as the execution date and time of the task.

  Subsequently, the task type determination unit 27 determines the type of task (task type) included in the presented task list (S209). The schedule related task selection unit 25 reads out the history of tasks having the same task type as the task included in the presented task list from the task selection history management table 22b, and includes it in the presented task list based on this history. The priority of the task to be obtained is obtained (S210), and the presented task list is rearranged according to this priority.

  Then, the schedule related task transmission unit 29 transmits the presented task list to the mobile communication terminal 14 (schedule related task transmission step: S211). The above is the process of selecting a candidate list of schedule-related tasks associated with this schedule information based on the user's schedule information, executed in the information distribution server 12.

  Subsequently, processing for distributing distribution information to the mobile communication terminal 14 executed in the information distribution server 12 will be described with reference to the flowchart of FIG. This process is executed by the information distribution server 12 after the process of registering the schedule related task by the mobile communication terminal 14 shown in FIG.

  First, the schedule request receiving unit 24 receives a schedule related task registered by the user of the mobile communication terminal 14 from the mobile communication terminal 14 (schedule related task receiving step: S301). With respect to each of the received schedule related tasks, the distribution information acquisition unit 30 refers to the distribution information management table 23a and acquires the distribution information category associated with the task ID of the task (distribution information acquisition step: S302). ).

  Subsequently, the optimum information delivery date estimation unit 31 refers to the delivery information browsing history management table 22c to determine the optimum delivery date of the delivery information category acquired by the delivery information acquisition unit 30 (S303). Specifically, the data in the “browsing time” column of the distribution information browsing history management table 22c is set as the optimal distribution date.

  Subsequently, the distribution information category selection unit 32 calculates the daily weight for each piece of distribution information based on the optimal distribution date of each distribution information set by the optimal information distribution date and time estimation unit 31 (S304). Specifically, for example, the weight of the optimal distribution date is set to 1, and is set so as to decrease by 0.1 for every day deviated.

  Subsequently, the distribution information acquisition unit 30 checks whether there is any other schedule information transmitted from the mobile communication terminal 14 (S305). If there is other schedule information, the process returns to step S301 and the processes of steps S301 to S304 are repeated until there is no more schedule information.

  If it is determined in step S305 that there is no other schedule information transmitted from the mobile communication terminal 14, the distribution information category selection unit 32 performs daily mobile communication terminal based on the weights of all distribution information categories. 14 is calculated, and a distribution information list for each day is generated based on the calculation results (S306). Specifically, for example, each weight of distribution information is compared every day, a predetermined number of distribution information is selected in descending order of weight, and the frequency of distribution is set according to the weight ratio.

  The distribution information list generated by the distribution information category selection unit 32 is held in the distribution information transmission unit 33 together with the contents of the distribution information. Then, the distribution information transmitting unit 33 distributes the distribution information to the mobile communication terminal 14 in accordance with the distribution timing set in the distribution information list (distribution information transmission step: S307). The processing for distributing distribution information to the mobile communication terminal 14 executed in the information distribution server 12 has been described above.

  Then, the effect | action and effect of the information delivery server 12, the mobile communication terminal 14, and the information delivery system 10 which concern on this embodiment are demonstrated.

  According to this embodiment, when the history request receiving unit 24 of the information distribution server 12 receives the user's schedule information transmitted from the input information transmitting unit 50 of the mobile communication terminal 14, the schedule related task selecting unit 25 performs task model management. With reference to the table 21a, the candidate list of the schedule related task associated with the “schedule category” of the received schedule information is selected, and the schedule related task transmission unit 29 moves the selected schedule related task candidate list to the mobile communication. It transmits to the schedule related task input part 52 of the terminal 14. The user of the mobile communication terminal 14 selects and registers a desired task from the candidate list of scheduled related tasks transmitted from the information distribution server 12. Thereby, the input of the schedule information using the mobile communication terminal 14 is supported, and the burden of the user inputting detailed schedule information can be reduced.

  In the information distribution server 12 of the present embodiment, the task profile matching unit 28 refers to the profile management table 22a to acquire profile information corresponding to the user ID of the mobile communication terminal 14, and refers to the task attribute management table 21b. Then, selectable conditions are acquired for each candidate list of scheduled related tasks selected by the scheduled related task selection unit 25, the profile information and the selectable conditions should be collated and transmitted to the mobile communication terminal 14. Select a task. Thereby, it becomes possible to select a schedule related task in consideration of a user's attribute, and it is possible to provide a candidate related task candidate list that matches each user's preference for each user.

  Further, in the information distribution server 12 of the present invention, the schedule related task selection unit 25 refers to the task selection history management table 22b, acquires a selection history for each candidate list of schedule related tasks, and based on this selection history Rearrange the candidate list. With this configuration, the candidate list of scheduled related tasks transmitted to the mobile communication terminal 14 is rearranged based on the selection history indicating that the user has selected the task in the past. Thereby, for example, tasks that are likely to be selected by the user are rearranged at the top of the list, so that the burden on the user to input detailed schedule information can be further reduced.

  Further, in the information distribution server 12 of the present invention, the schedule related task selection unit 25 displays a selection history of a task having the same type as the type of the schedule related task determined by the task type determination unit 27 as a task selection history management table 22b. And sort the candidate list of scheduled related tasks based on this selection history. According to this configuration, the candidate related task candidate list transmitted to the mobile communication terminal 14 is rearranged using a task selection history of the same type as the task that the user has selected in the past. Thereby, even when the user's selection history is not sufficiently accumulated, it is possible to provide a schedule related task that is highly likely to be selected by the user.

  Further, in the information distribution server 12 of the present invention, the optimal information distribution date estimation unit 31 refers to the distribution information browsing history management database, and the distribution information browsing history transmitted to the mobile communication terminal 14 by the distribution information transmitting unit 33. Is obtained, and the timing for transmitting the distribution information is obtained based on the browsing history. With this configuration, the optimal distribution date and time of distribution information can be determined for each user based on the browsing history of distribution information transmitted to the user in the past. As a result, it is possible to distribute distribution information in consideration of individual user preferences, and distribution information based on schedule information can be distributed at an appropriate timing.

  In the information distribution server 12 of the present invention, the distribution information category selection unit 32 transmits the distribution information obtained by the optimum information distribution date and time estimation unit 31 for each of the distribution information acquired by the distribution information acquisition unit 30. A priority weighted around the timing is calculated, and distribution information to be distributed to the mobile communication terminal 14 is selected based on the priority. With this configuration, even when a plurality of schedule information is registered by the user, the distribution information to be distributed to the mobile communication terminal is considered in consideration of the priority weighted based on the date and time when each distribution information is scheduled to be distributed. Since the decision is made, high priority information can be distributed in consideration of all schedules.

  Next, a method for spontaneously distributing distribution information after a predetermined period has elapsed since the candidate list was transmitted will be described. In the information distribution server 12 of the present invention, the history request receiving unit 24 includes the schedule related task selected by the user within a predetermined period from the date and time when the schedule related task transmitting unit 29 transmits the candidate list of scheduled related tasks to the mobile communication terminal 14. It is determined whether or not the task is received from the mobile communication terminal 14. When the history request receiving unit 24 has not received the schedule related task from the mobile communication terminal 14, all the tasks related to the schedule related task candidate list already transmitted to the mobile communication terminal 14 are regarded as the schedule related task selected by the user, The distribution information acquisition unit 30 acquires the distribution information associated with the schedule related task regarded with reference to the distribution information management table 23a. Then, the optimal information distribution date and time estimation unit 31 obtains the timing for transmitting the distribution information, the distribution information category selection unit 32 selects the distribution information to be distributed, and the distribution information transmission unit 33 sets the selected distribution information as the timing information. It transmits to the mobile communication terminal 14 at the timing according to. FIG. 19 shows a flowchart of this configuration. After the presentation task list is transmitted to the mobile communication terminal 14 by the schedule related task transmission unit 29 (S211 in FIG. 17), the information distribution server 12 receives the history request reception unit within a predetermined time from the transmission timing of the presentation task list. It is determined whether 24 has received the schedule related task selected by the user from the mobile communication terminal 14 (S401). If it is determined in step S401 that the schedule-related task has been received, the process proceeds to step S301 in FIG. On the other hand, if it is determined in step S401 that no schedule-related task is received, all tasks in the presented task list transmitted in step S211 are regarded as schedule-related tasks (step 402), and the processes after step S403 are executed. Steps S403, S404, S405, S406, S407, and S408, which are subsequent processes, correspond to steps S302, S303, S304, S305, S306, and S307 in FIG. 18, respectively. , Omit the explanation.

  With this configuration, even if the user does not select the candidate list of scheduled related tasks transmitted to the mobile communication terminal 14, the user is desired while saving the user from selecting the candidate list of scheduled related tasks. It will be possible to distribute distribution information. In addition, it is preferable that the user can set in advance whether to enable or disable the operation with this configuration.

  Next, a method for spontaneously distributing distribution information based on the optimal distribution date of distribution information will be described. As described above, with reference to FIG. 18, when the history request receiving unit 24 receives the schedule-related task selected by the user as a trigger, the distribution information corresponding to the received schedule-related task is acquired and an appropriate timing is acquired. I explained the configuration to be distributed in. In contrast, in this method, the schedule-related task selection unit 25 does not wait for receiving the schedule-related task selected by the user (the delivery timing may be exceeded if the task is permanently waited). After the related task is selected, all the tasks related to the schedule related task candidate list transmitted by the schedule related task transmission unit 29 are regarded as the schedule related task selected by the user. The distribution information acquisition unit 30 acquires the distribution information associated with the schedule related task regarded with reference to the distribution information management table 23a. Then, the timing for transmitting the distribution information is obtained by the optimum information distribution date and time estimation unit 31, the distribution information to be distributed is selected by the distribution information category selection unit 32, and the timing according to the timing information of the target distribution information is reached. When the schedule related task selected by the user is not received by the history request receiving unit 24, the distribution information transmitting unit 33 transmits the target distribution information to the mobile communication terminal 14. FIG. 20 shows a flowchart of this configuration. After the presentation task list is transmitted to the mobile communication terminal 14 by the schedule related task transmission unit 29 (S211 in FIG. 17) (however, the information distribution server 12 may be after the presentation task list is constructed), All tasks in the presented task list transmitted in S211 are regarded as schedule-related tasks (S221), and the processes after step S222 are executed. Steps S222, S223, S224, S225, and S226, which are subsequent processes, correspond to Step S302, Step S303, Step S304, Step S305, and Step S306 in FIG. After the generation of the distribution information list in step S226, the history request receiving unit 24 selects the schedule related task selected by the user even when the distribution information transmitting unit 33 distributes the target distribution information. It is determined whether it has not been received (S227). If it is determined in step S227 that the history request receiving unit 24 is receiving, the process proceeds to step S301 in FIG. On the other hand, if it is determined in step S227 that the history request receiving unit 24 has not received, the target distribution information is transmitted to the mobile communication terminal 14 (S228).

  With this configuration, similar to the distribution information spontaneous distribution method described with reference to FIG. 19, the distribution information that the user may desire while omitting the user's trouble of selecting a candidate list of schedule-related tasks. Can be delivered.

  In the configuration of the distribution information voluntary distribution method described with reference to FIG. 20, the schedule related task selected by the user from the mobile communication terminal 14 after the selection of the distribution information and the distribution timing of the distribution information is determined. In such a case, the processing of step 301 may be executed again. In this case, the distribution information associated with a task other than the schedule-related task selected by the user among the distribution information that has already been selected. It can also be set as the structure delivered about the delivery information which remained after deletion.
