FIG. 1 is a diagram showing a configuration of a memo information management system 10 according to the present embodiment. The memo information management system 10 includes a memo information management server 1, a mobile terminal 3, and a meta information server 5. The memo information management server 1 can communicate with the mobile terminal 3 via the network N1, and can also communicate with the meta information server 5 via the network N2.

  Note that the memo information management server 1, the mobile terminal 3, and the meta information server 5 are mutually connected via the Internet, a cellular network for mobile objects, or a network such as a dedicated line (network N1 and network N2). Although it is assumed that the devices are connected to each other, the present invention is not limited to this, and some or all of the functions of the memo information management server 1, the mobile terminal 3, and the meta information server 5 may be combined into one or two. Implementations in either a centralized form or distributed over four or more devices are possible. When the functions of the memo information management server 1, the mobile terminal 3, and the meta information server 5 are mounted on one device, the memo information management server 1, the mobile terminal 3, and the meta information server 5 communicate with each other. The network (network N1 and network N2) for performing communication corresponds to a communication bus or the like for transmitting and receiving signals within the one device.

  The memo information management server 1 manages the contents of memo information transmitted from the mobile terminal 3. The memo information is data input to the mobile terminal 3, for example, an object (for example, purchase of an article or a visit to a facility) performed by a user of the mobile terminal 3 (a “category” indicating an article or a facility described later). ", For example," Music CD "), and the contents accompanying this" Category "content (" Free Text ", which will be described later, for example," Buy when I see ") Including. Details of the configuration of the memo information management server 1 will be described later.

  In other words, the memo information is intended to be implemented at a certain time when the user of the mobile terminal 3, but cannot be implemented due to reasons such as the object is not available for purchase or available at this time. It refers to electronic data recorded in the mobile terminal 3 to remember about this. Operations related to the implementation (for example, “purchase” and “use”) and operation targets (for example, “music CD”, “accommodation facility”, etc.) are included.

  “Category” refers to such an operation target. Data indicating the content of “category” is input to the mobile terminal 3 as data constituting memo information. In addition, “free text”, in other words, can be recalled by the user of items that the user of the mobile terminal 3 wants to remember along with the contents of “category”, such as “buy when I see”. It refers to the content expressed to the extent. More specifically, the content of “free text” includes an operation related to what the user of the mobile terminal 3 tried to perform (for example, “purchase” or “use”), or a target of this operation (for example, "Music CD", "accommodation facilities", etc.). The content of this “free text” is input to the mobile terminal 3 as the content of the memo information together with the content of “category”.

  The mobile terminal 3 is a mobile communication terminal, such as a mobile phone. Functionally, the mobile terminal 3 includes a communication unit 3a, a memo information display unit 3b, a memo information input unit 3c, and a position information acquisition unit 3d.

  The CPU 11 executes the above computer program (in particular, the communication unit 1a, the memo information recording unit 1b, the memo information notification control unit 1d, the memo information update unit 1e, the proximity determination unit 1f, and the situation determination unit 1g shown in FIG. 2). The date information acquisition unit 1h, the schedule information acquisition unit 1i, the location information acquisition unit 1j, the usable period determination unit 1m, the information update date determination unit 1n, and the update date history information database 1p), the memo information management server 1 Processing to be performed (processing performed by the memo information management server 1 in the flowcharts shown in FIGS. 3 to 12) is executed.

  The communication unit 1a has an interface for transmitting and receiving data to and from the mobile terminal 3 via the network N1 using the communication device 14. The memo information recording unit 1b receives the memo information (including the contents of “category” and the content of “free text”) transmitted from the mobile terminal 3 via the communication unit 1a, and receives the received memo information as a memo. Store in the information database 1c.

  The memo information notification control unit 1d includes a use permission determination unit 1d1 and a notification permission determination unit 1d2. The memo information notification control unit 1d sequentially takes out the memo information stored in the memo information database 1c one by one, information indicating whether the memo information can be used, which is a determination result of the availability determination unit 1d1, The memo information can be used based on the determination result of the notification enable / disable determination unit 1d2 indicating that “notifying the user of the contents of the current memo information is valid” (in this case, whether the notification is possible or not) If it is "YES") and it is effective for the user to notify the contents of the memo information now (in this case, whether the notification is possible is "YES"), the memo information is It is determined to notify the user, and an instruction signal for instructing the mobile terminal 3 to notify the content of the memo information is transmitted to the mobile terminal 3 together with the memo information.

  The availability determination unit 1d1 acquires usage conditions (for example, planned release date, opening hours, store location, etc.) of the memo information from the memo information stored in the memo information database 1c, and based on the acquired usage conditions. To determine whether the memo information can be used.

  When the content of “category” included in the memo information is any of “music CD”, “DVD”, and “book”, the availability determination unit 1d1 first determines the current date and time information acquisition unit 1h. To get. Next, the availability determination unit 1d1 acquires the contents of the “scheduled release date” of the memo information, and the planned release date indicated in the “scheduled release date” and the current date / time information acquisition unit 1h acquire the information. Compare the date and time. The availability determination unit 1d1 determines that the availability of the memo information is “YES” (the memo information can be used) when the current date has passed the scheduled release date indicated in the “scheduled release date”. The set value of “YES” can be recorded in the memo information by the availability determination unit 1d1, or the memo information management server 1 such as the memo information database 1c is associated with the memo information by the availability determination unit 1d1. Can be recorded in a built-in memory (RAM 13, recording device 15, etc.). If the set value of “YES” is used, the subsequent availability determination process by the availability determination unit 1d1 can be omitted.

  When the content of “category” in the memo information is “restaurant”, the availability determination unit 1d1 causes the date information acquisition unit 1h to acquire the current date and time. Next, the availability determination unit 1d1 acquires the contents of the “opening time zone” of the memo information, and the current time and date acquired by the time information indicated by the “opening time zone” and the date and time information acquiring unit 1h. And compare. When the current date and time is within the time zone indicated in the “opening time zone”, the availability determination unit 1d1 makes a proximity determination to the location indicated in the “store position” of the memo information to the proximity determination unit 1f. Let it be done.

  When the proximity determination result by the proximity determination unit 1f indicates “close” (that is, the current position of the mobile terminal 3 is close to the position indicated by “store position”) If it is determined that the memo information can be used, it is determined as “YES” (the memo information can be used).

  When the content of the “category” of the memo information is “accommodation facility”, the availability determination unit 1d1 first causes the proximity determination unit 1f to perform the proximity determination with respect to the position indicated by the “store position” of the memo information. . When the proximity determination result by the proximity determination unit 1f indicates “close”, the availability determination unit 1d1 determines that the availability of the memo information is “YES” (memo information can be used).

  The notification availability determination unit 1d2 indicates status information indicating the current status of the user of the mobile terminal 3 based on the schedule information of the user of the mobile terminal 3 (for example, information indicating work, business trip, going to work / going home, staying home, going out, etc.) ), And based on the acquired status information, it is determined whether or not the mobile terminal 3 is to be notified of the contents of the memo information determined to be usable by the availability determining unit 1d1. For example, the notification availability determination unit 1d2 informs the user that the notification of the memo information is disadvantageous regardless of the content of the memo information, such as inducing work interruption when notifying the memo information or causing discomfort to surrounding people. If not, it is determined whether the notification is possible or not as “YES” (corresponding to a notification situation).

  Specifically, the notification availability determination unit 1d2 estimates based on schedule information indicating the schedule of the user of the mobile terminal 3, and the current time and / or the current user position (current position of the mobile terminal 3). It is determined whether the notification of the memo information is disadvantageous for the user from the current situation of the user (for example, at work, on a business trip, going to work / going home, staying at home, going out, etc.) Based on the above, it is determined whether or not notification indicating whether or not notification of memo information is possible.

  A more specific procedure is shown below. First, the notification availability determination unit 1d2 obtains the schedule information of the user of the mobile terminal 3 acquired from the schedule information database 1k by the schedule information acquisition unit 1i and the current date and time acquired by the date and time information acquisition unit 1h. If the current time is within the scheduled time for work or business trip, it is determined that the notification is “NO” (not applicable to the notification situation). When the current date / time acquired by the date / time information acquisition unit 1h is within the time of a schedule other than work or business trip (travel or meal), the notification availability determination unit 1d2 determines “YES” If the schedule does not exist, the situation determination unit 1g is made to determine the situation of the user of the mobile terminal 3 using the position information of the mobile terminal 3. For example, when the user is “working” or “at home” as a result of the determination by the situation determination unit 1g, the notification availability determination unit 1d2 determines the notification availability as “NO” (does not correspond to the notification situation), and Otherwise (“commuting / going home” or “going out”), it is determined whether the notification is “YES” (corresponding to a notification situation).

  For each schedule of schedule information stored in the schedule information database 1k, a flag indicating whether or not notification is possible ("YES" flag indicating that it corresponds to a notification situation or that it does not correspond to a notification situation) A configuration in which a “NO” flag) is set in advance may be employed. In this case, the notification availability determination unit 1d2 can determine whether to notify the content of the memo information by referring to the flag of the schedule information.

  The proximity determination unit 1f is based on the contents (latitude and longitude) of the “store position” of the memo information notified from the availability determination unit 1d1 and the position of the mobile terminal 3 acquired by the position information acquisition unit 1j. When it is determined that 3 is close to “store position” (latitude and longitude) (for example, when the mobile terminal 3 is in a circular area having a predetermined radius centered on “store position”), this determination result Notify the availability determining unit 1d1 of “close”.

  The situation determination unit 1g includes the current date and time acquired by the date and time information acquisition unit 1h, the position of the mobile terminal 3 acquired by the position information acquisition unit 1j, and the work location of the user of the mobile terminal 3 (of the building of the work site). The mobile terminal 3 user status, that is, whether the user of the mobile terminal 3 is “going home / going home”, “going home”, “ Whether it is “at home” or “at work” is determined. The information indicating the work location of the user of the mobile terminal 3 and the information indicating the home position of the user of the mobile terminal 3 are both transmitted from the mobile terminal 3 in advance, and are incorporated in the memo information management server 1. It is stored in a memory (RAM 13 or recording device 15).

  The situation determination unit 1g is a case where the current date and time acquired by the date and time information acquisition unit 1h is in a time zone on weekdays (from Monday to Friday) and in the daytime (for example, from 6 am to 8 pm), When the mobile terminal 3 is within a certain range from the work location of the user of the mobile terminal 3 (for example, within a circular area with a predetermined radius centered on the work building), it is determined as “working” Even when the current date and time acquired by the date and time information acquisition unit 1h is in a weekday and daytime period, the mobile terminal 3 is not within a certain range from the work location of the user of the mobile terminal 3. Is determined to be “going to work / going home”.

  The situation determination unit 1g is a case where the current date and time acquired by the date and time information acquisition unit 1h is not a weekday and daytime time zone, and the position of the mobile terminal 3 acquired by the location information acquisition unit 1j is the mobile terminal 3 is within a certain range from the home position of the user 3 (for example, within a circular area with a predetermined radius centered on the home), the current date / time is determined to be “at home” and acquired by the date / time information acquisition unit 1h. If the mobile terminal 3 that is acquired by the location information acquisition unit 1j is not within a certain range from the home position of the user of the mobile terminal 3, the “outing” It is determined as “medium”. The situation determination unit 1g can also determine in detail the situation of the user of the mobile terminal 3 by using a plurality of time-series positions as the position of the mobile terminal 3 acquired by the position information acquisition unit 1j. .

  The date and time information acquisition unit 1h acquires the current date and time by the timekeeping function by the CPU 11 of the memo information management server 1, or acquires the current date and time from the network N1 or the network N2. The schedule information acquisition unit 1i acquires the schedule information of the user of the mobile terminal 3 stored in the schedule information database 1k and passes it to the memo information notification control unit 1d. The schedule information stored in the schedule information database 1k is transmitted from the mobile terminal 3, or directly input from the memo information management server 1.

  The memo information update unit 1e updates the memo information (including replenishment, and so on) using the contents of “category” and “free text” of the memo information stored in the memo information database 1c. Meta information to be acquired is acquired from the meta information server 5, and the acquired meta information is added to the memo information and stored again in the memo information database 1c.

  The memo information update unit 1e includes a regular update unit 1e1 and an update unit 1e2, and updates the memo information in the memo information database 1c (that is, the meta information included in the memo information) to the regular update unit 1e1 and the update unit 1e2. Update the contents of the information part). The regular update unit 1e1 and the update unit 1e2 each update the memo information at different timings. Both the steady update unit 1e1 and the update unit 1e2 update the memo information in the memo information database 1c based on the latest meta information of the meta information server 5 while suppressing the load applied to the meta information server 5.

  For example, when the content of the “category” of the memo information is “book”, “music CD”, “DVD”, etc., the regular update unit 1e1 releases the release date information at the beginning of the month by the release source (publisher or label), Regular meta information update timing (regular update date) such as regular meta information update work by the administrator of the meta information server 5 is detected, and updated (latest) according to the regular update date. The meta information is acquired from the meta information server 5, and the memo information in the memo information database 1c is updated using the acquired latest meta information.

  The update process of the memo information by the steady update part 1e1 is shown concretely. First, the steady updating unit 1e1 acquires one piece of memo information from the memo information database 1c, and transmits the acquired memo information to the usable period determining unit 1m. The available period determination unit 1m includes a period (for example, a music CD) that the user can use, such as “scheduled release date” in the case of memo information of a music CD, among the memo information transmitted from the steady update unit 1e1. Items related to the period during which the purchase is possible and the opening hours, etc.) are acquired, whether or not a specific period / date is set in this item, and the determination result is notified to the steady update unit 1e1. To do.

  The regular update unit 1e1 determines that the specific period / date is not set in the item of the memo information transmitted to the available period determination unit 1m, and determines that the available period determination unit 1m determines the previous time of the memo information. If x days (x is an integer equal to or greater than 1) have passed since the update date, update processing of the memo information is started.

  The update date of the memo information can be recorded in the memo information by the memo information update unit 1e after the memo information is updated. Data indicating the value of x indicating the number of days elapsed is stored in advance in a built-in memory such as the ROM 12 of the memo information management server 1. When the value of x indicating the number of days elapsed is relatively small, when the meta information of the meta information server 5 is updated (for example, when the planned release date of the music CD is determined), it is updated in a relatively short time. The latest latest meta information can be reflected in the memo information in the memo information database 1c. However, in this case, since the number of accesses to the meta information server 5 is relatively large, the load on the meta information server 5 increases. Therefore, the value of x indicating the number of days elapsed is determined in consideration of the load on the meta information server and the accuracy of notification of memo information (including the probability of notification of memo information, the probability of scheduled notification date, etc.). .

  When the availability period determination unit 1m determines that the specific period / date is set in the item of the memo information transmitted to the availability period determination unit 1m, the steady update unit 1e1 The memo information is updated based on the past update date history (the update date history is stored in the update date history information database 1p).

  First, the steady update unit 1e1 determines the information source of the meta information (for example, the content of the meta information part (for example, the meta information part shown in FIG. 15) or “category”) acquired from the memo information database 1c. The information source D32) shown in FIG. 16 is acquired. After acquiring the information source of meta information, the regular update unit 1e1 causes the information update date determination unit 1n to calculate a periodic update date corresponding to the acquired information source.

  The information update date determination unit 1n first acquires the update date history so far corresponding to the information source of the meta information from the update date history information database 1p. The update date history acquired by the information update date determination unit 1n can be traced back from the current time by a predetermined period (for example, the past year), but all data stored in the update date history information database 1p. It can also be acquired from the inside.

  The information update date determination unit 1n acquires all day values from the acquired update date history, and calculates a variance value related to “day of the week”. In this case, different numerical values are set for each day of the week from Sunday to Saturday (data indicating the numerical values is stored in advance in a built-in memory such as the ROM 12 of the memo information management server 1).

  The information update date determination unit 1n uses the numeric value of the day of the week acquired from the update date history and the number of times of each day of the week to calculate a variance value related to “day of the week” and an average value related to “day of the week”. calculate. The information update date determination unit 1n determines that there is a tendency to be updated on a specific day of the week when the calculated variance for the “day of the week” is less than or equal to the reference variance “m”, and the average value for the “day of the week” The day of the week corresponding to the numerical value closest to is specified, and the date corresponding to the specified day of the week after today is determined as the regular update date, and the determination result is notified to the steady update unit 1e1. The information update date determination unit 1n can calculate the average value related to “day of the week” after obtaining the result that the variance value related to “day of the week” is equal to or less than the reference variance value “m”.

  For example, the reference variance value “m” is set to “1” (m = 1), today is set to December 17, 2009, and the update date history information D3 shown in FIG. The value calculation process will be specifically described. First, the information update date determination unit 1n obtains, for example, only the row of “RRR record” that is an information source of meta information (that is, only the update date history of “RRR record”) from the update date history information D3.

  The update dates are 2009.11.2 (Monday), 2009.12.1 (Tuesday), 2009.11.10 (Tuesday), 2009.11.17 (Tuesday). Thus, the update is performed sequentially on Monday, Tuesday, Tuesday, and Tuesday. It is assumed that a numerical value “1” is set on Monday and a numerical value “2” is set on Tuesday (a numerical value set for each of Wednesday, Thursday, Friday, Saturday, and Sunday is “3”, for example) , “4”, “5”, “6”, “0”, etc.).

  The information update date determination unit 1n obtains “0.1875” by calculating the variance value related to “day of the week”, and further obtains “1.75” by calculating the average value related to “day of the week”. Since the variance value “0.1875” related to “day of the week” is equal to or less than the value “1” of the reference variance value “m”, the information update date determination unit 1n determines the average value “1. The day of the week corresponding to the numerical value “2” closest to 75 ”is specified (ie, Tuesday), and the date corresponding to this specified Tuesday after this day (ie, December 22, 2009) is the periodic update date. And the determination result is notified to the steady update unit 1e1.

  When the variance value relating to the calculated “day of the week” is greater than the reference variance value “m”, the information update date determination unit 1n determines the day value (1 to 31 from the update date history acquired from the update date history information database 1p. If the value is any value and the day is 17th, for example, "17") is acquired. The information update date determination unit 1n uses the value of the day acquired from the update date history and the number of times of each day to calculate the variance value related to “day” and the average value related to “day”. calculate.

  The information update date determination unit 1n determines that there is a tendency to be updated on a specific day when the calculated variance value related to “day” is equal to or less than the reference variance value “n”, and the average value related to “day” The date corresponding to the numerical value closest to is specified, the date corresponding to this specified date after today is determined as the regular update date, and the determination result is notified to the steady update unit 1e1.

  When the variance value relating to the calculated “day” is greater than the reference variance value “n”, the information update date determination unit 1n determines that the first day of the next month after today is the regular update date, and this determination The result is notified to the regular update unit 1e1, and the regular update date determination process is terminated. The information update date determination unit 1n can calculate the average value related to “day” after obtaining the result that the variance value related to “day” is equal to or less than the reference variance value “n”.

  If the regular update date (update date by the information source of the content of the meta information part included in the memo information) notified from the information update date determination unit 1n to the regular update unit 1e1 is not today, the memo information update unit 1e The update unit 1e2 is determined each time whether or not the update date of the meta information by the information source corresponds to the update date.

  The update date is the content of the meta information part determined by the update unit 1e2 each time according to the content of the schedule information based on the user's action schedule information such as the schedule information stored in the schedule information database 1k This is a suitable update timing.

  The update date is read by the user of the mobile terminal 3 according to the determination of the memo information notification control unit 1d that notifies the user of the mobile terminal 3 of the memo information or by the manual operation of the user of the mobile terminal 3. Is determined by the update unit 1e2 each time using the possibility that the meta information is updated (possibility of use) and the possibility that the meta information server 5 may update the meta information again after the meta information is updated (renewability possibility). The The update date determined in this way can be a date on which the availability of memo information is sufficiently high and the possibility of re-update of meta information after update is sufficiently low.

  In this embodiment, the update date is determined by the update unit 1e2 each time based on the schedule information of the user of the mobile terminal 3 stored in the schedule information database 1k. Specifically, the update unit 1e2 refers to the schedule information of the user of the mobile terminal 3 every time, and when there is a plan to go out on the next day (travel, business trip, meal, etc.), the update unit 1e2 uses it on the day before this planned going out date. It can be determined that the possibility is the highest.

  Each time the update unit 1e2 also has a monotonically decreasing function (for example, the number of days elapsed from the regular update date) that minimizes the possibility of re-updating on the regular update date of the meta information calculated by the information update date determination unit 1n. Renewability is possible using the function that indicates the possibility of renewal for the function, and the renewability is monotonously decreased with the increase in the number of days in the period from the day following the regular renewal date to the regular renewal date) Sex can be evaluated.

  Then, each time the update unit 1e2 uses the availability and re-updability as described above, the day before the planned outing date recorded in the schedule information is set as the update date, and the memo information update unit 1e The contents of the meta information part of the memo information are updated on the update date each time.

  The memo information update unit 1e, when today corresponds to at least one of the regular update date and the update date each time, the necessary information (meta information corresponding to the information source of the content of the meta information part of the memo information) After acquiring from the server 5 and updating the memo information using the acquired meta information, the meta information update date (referred to as the first update date) used for updating the memo information is included in the meta information. The update date history or the update date history of the meta information acquired via the meta information server 5 is acquired, and the latest update date (referred to as the second update date) for the meta information is further updated. Obtained from the update date history information D3 of the information database 1p. The memo information update unit 1e compares the first update date and the second update date, and if the first update date is later than the second update date, the information source of the update date history information D3 The first date is reflected in the update date history and used for the calculation of the regular update date after today.

  Next, the operation of the memo information management system 10 according to the embodiment will be described with reference to the flowcharts of FIGS.

  The memo information registration process will be described with reference to FIG. The memo information input unit 3c of the mobile terminal 3 displays the “category” and “free text” input fields included in the memo information on the display device of the mobile terminal 3, and inputs “category” and “free text”. To the user (step A1). Then, it is monitored whether or not the user inputs “category” and / or “free text” (step A2). If there is an input (step A2; Yes), the communication unit 3a of the mobile terminal 3 The memo information including the contents of the input “category” and / or “free text” is transmitted to the memo information management server 1. Thereafter, the communication unit 1a of the memo information management server 1 receives the memo information (including “category” and / or “free text” information) transmitted from the mobile terminal 3 via the network N1. Then, the memo information recording unit 1b of the memo information management server 1 receives the keyword (category, product name, etc.) included in the content of “category” or “free text” of the memo information received by the communication unit 1a. Meta information corresponding to (information shown) is acquired from the meta information server 5 via the network N2 (step A3).

  The memo information recording unit 1b of the memo information management server 1 determines whether or not there is only one meta information acquired from the meta information server 5 (step A4), and determines that there is only one (step A4). Yes), the content of the meta information is included in the memo information including “category” and “free text”, and the memo information including the content of the meta information is stored in the memo information database 1c of the memo information management server 1. Store (step A7). When the memo information recording unit 1b of the memo information management server 1 determines that a plurality of pieces of meta information have been acquired as a result of determining whether or not the meta information acquired from the meta information server 5 is only one (step A4). No), transmitting all of the plurality of meta information to the mobile terminal 3 via the network N1, requesting selection input of one meta information (step A5), and responding to this request, the user of the mobile terminal 3 When the selection input of one piece of meta information is performed in the mobile terminal 3 (step A6; Yes), the selected one piece of meta information is received from the mobile terminal 3, and the received one piece of meta information is received. Then, the process of step A7 is performed.

  The memo information update process will be described with reference to FIG. The regular update unit 1e1 acquires one piece of memo information from the memo information database 1c, and transmits the acquired memo information to the available period determination unit 1m (step B1). The available period determination unit 1m can be used by the user such as “scheduled release date” in the case of memo information of a music CD among the memo information transmitted from the steady update unit 1e1 (for example, purchase of a music CD) An item related to the period is acquired, it is determined whether or not a specific period / date is set in this item, and the determination result is notified to the steady update unit 1e1 (step B2).

  Based on the determination result by the available period determination unit 1m performed in step B2, the regular update unit 1e1 has a specific period / date set in the item of the memo information transmitted to the available period determination unit 1m. If it is determined that there is not (Step B3; No), it is determined whether or not x days (x is an integer of 1 or more) have passed since the previous update date of the memo information (Step B10), and x days have passed. If it is determined that it has been determined (step B10; Yes), the process proceeds to step B11. If it is determined that x days have not elapsed (step B10; No), the process returns to step B1.

  In step B3, the steady updating unit 1e1 sets a specific period / date in the item of the memo information transmitted to the usable period determining unit 1m based on the determination result by the usable period determining unit 1m performed in step B2. Is determined (step B; Yes), the information source of the content of the meta information part from the meta information part (for example, meta information shown in FIG. 15) of the memo information acquired from the memo information database 1c. (For example, the information source D32 shown in FIG. 16) is acquired (step B4).

  After acquiring the information source in step B4, the regular update unit 1e1 causes the information update date determination unit 1n to calculate a regular update date corresponding to the acquired information source (step B5). The memo information update unit 1e determines whether the regular update date notified from the information update date determination unit 1n to the regular update unit 1e1 after step B5 is today (step B6). When the memo information update unit 1e determines that the regular update date is today (step B6; Yes), the process proceeds to step B11. When the memo information update unit 1e determines that the regular update date is not today (step B6; No), the acquisition is performed in step B1. The update unit 1e2 is determined each time whether or not the update date of the meta information by the information source of the meta information portion of the memo information that has been received corresponds to the update date.

  After step B6 (No), the update unit 1e2 refers to the schedule information of the user of the mobile terminal 3 stored in the schedule information database 1k, and acquires tomorrow's schedule from this schedule information (step B7). . Then, the update unit 1e2 determines whether or not the tomorrow's schedule acquired in step B7 is going to go out (step B8), and determines that it is going to go out (step B8; Yes), the process proceeds to step B11, and if it is determined that it is not scheduled to go out (step B8; No), it is determined whether or not this update process has been performed on all the memo information in the memo information database 1c. (Step B9), when it is determined that the memo information that has not been subjected to the update process is present in the memo information database 1c (Step B9; No), the process proceeds to Step B1, and all the memo information in the memo information database 1c is processed. If it is determined that the update process has been performed (step B9; Yes), the update process ends.

  After step B6 (Yes), step B8 (Yes), and step B10 (Yes), in step B11, the memo information update unit 1e updates the latest meta information corresponding to the information source of the memo information acquired in step B4. Then, it is obtained from the meta information server 5 (the latest meta information is always stored in the meta information server 5), and the memo information is updated using the obtained meta information (step B11). After step B11, the memo information update unit 1e performs an update process on the update date history (update date history stored in the update date history information database 1p) of the meta information acquired in step B11 (step B12). The process proceeds to step B1.

  The information source acquisition process will be described with reference to FIG. The processing content shown in the flowchart of FIG. 5 is the processing content of step B4 in the flowchart of FIG. The regular update unit 1e1 acquires the content of “category” included in the memo information acquired in advance from the memo information database 1c (step C1). The steady updating unit 1e1 determines whether or not the content of the “category” acquired in step C1 is “book” (step C2). If it is determined as “book” (step C2; Yes), the memo The contents of the “publisher” included in the meta information part of the information are acquired (step C5), and the meta information for the information source of the contents of the “publisher” is acquired from the meta information server 5.

  When the steady update unit 1e1 does not determine “book” in step C2 (step C2; No), the content of the “category” acquired in step C1 is “music CD” or “DVD”. It is determined whether or not there is (step C3), and when it is determined that the data is either “music CD” or “DVD” (step C3; Yes), the “label” included in the meta information portion of the memo information Information is acquired (step C 6), and meta information that uses the content of the “label” as an information source is acquired from the meta information server 5. When the steady updating unit 1e1 does not determine that the data is “music CD” or “DVD” in step C3 (step C3; No), the content of the “category” of the memo information is used as the information source. Meta information is acquired from the meta information server 5 (step C4).

  With reference to FIG. 6, the process of calculating the periodic update date will be described. The processing content shown in the flowchart of FIG. 6 is the processing content of step B5 in the flowchart of FIG. First, the information update date determination unit 1n acquires the update date history so far corresponding to the information source of the meta information part of the memo information from the update date history information database 1p (step D1).

  The update date history acquired by the information update date determination unit 1n can be traced back from the current time by a predetermined period (for example, the past year), but all data stored in the update date history information database 1p. It can also be acquired from the inside. The information update date determination unit 1n acquires all values of the day of the week from the acquired update date history, and calculates a variance value related to “day of the week” (step D2). In this case, different numerical values are set for each day of the week from Sunday to Saturday (data indicating these numerical values is stored in advance in a built-in memory such as the ROM 12 of the memo information management server 1).

  The information update date determination unit 1n uses the numeric value of the day of the week acquired from the update date history and the number of times of each day of the week to calculate a variance value related to “day of the week” and an average value related to “day of the week”. calculate. The information update date determination unit 1n determines that there is a tendency to be updated on a specific day of the week when the calculated variance value related to “day of week” is equal to or less than the reference variance value “m” (step D3; Yes). The day of the week corresponding to the average value related to the “day of the week” is specified (step D7), and the date corresponding to the specified day of the week after today is determined as the periodic update date. The steady update unit 1e1 is notified (step D8). The information update date determination unit 1n can calculate the average value related to “day of the week” after obtaining the result that the variance value related to “day of the week” is equal to or less than the reference variance value “m”.

  When the variance value related to “day of the week” calculated in step D2 is greater than the reference variance value “m” (step D3; No), the information update date determination unit 1n updates the update date history acquired from the update date history information database 1p. To the day value (any value from 1 to 31 and “17” if “day” is 17 days, for example), and the date value obtained from this update date history and each day Using each number of times, a variance value related to “day” and an average value related to “day” are calculated (step D4).

  The information update date determination unit 1n determines that there is a tendency to be updated on a specific day when the variance value related to “day” calculated in step D4 is equal to or less than the reference variance value “n” (step D5; Yes). The date corresponding to the numerical value closest to the average value related to “day” is specified (step D9), and the date corresponding to the specified date after today is determined as the periodic update date, and the determination result Is notified to the regular update unit 1e1 (step D10).

  If the variance value related to “day” calculated in step D4 is greater than the reference variance value “n” (step D5; No), the information update date determination unit 1n determines the first day of the next month after today. The regular update date is determined, the determination result is notified to the regular update unit 1e1 (step D6), and the regular update date calculation process is terminated. The information update date determination unit 1n can calculate the average value related to “day” after obtaining the result that the variance value related to “day” is equal to or less than the reference variance value “n”.

  The update date history update process will be described with reference to FIG. The processing content shown in the flowchart of FIG. 7 is the processing content of step B12 in the flowchart of FIG. The memo information update unit 1e acquires the update date (referred to as the first update date) of the meta information used for updating the memo information via the update date history included in the meta information or the meta information server 5. An update date history of the meta information is acquired (step E1).

  After step E1, the memo information update unit 1e updates the latest update date (the first update date) of the meta information recorded in the update date history information (update date history information D3) stored in the update date history information database 1p. 2) is acquired from the update date history information in the update date history information database 1p (step E2).

  After step E2, the memo information update unit 1e compares the first update date and the second update date (step E3), and if the first update date is later than the second update date (step E3) E3; Yes), the first update date is reflected in the update date history of the meta information of the information source in the update date history information (step E4), and is used for the calculation of the regular update date after this date.

  The memo information notification process will be described with reference to FIG. The memo information notification control unit 1d acquires one piece of memo information stored in the memo information database 1c (step F1). After step F1, the memo information notification control unit 1d causes the availability determination unit 1d1 to perform a process for determining whether the memo information can be used (step F2). After step F2, the memo information notification control unit 1d determines whether or not the use availability determination result by the use availability determination unit 1d1 is “YES” (step F3).

  In step F3, when the determination result of availability is not “YES” (step F3; No), the process proceeds to step F7, and when the determination result of availability is “YES” (step F3; Yes), step F4. Migrate to In step F4, the memo information notification control unit 1d causes the notification enable / disable determination unit 1d2 to perform determination processing of whether or not to notify memo information (step F4). After step F4, the memo information notification control unit 1d determines whether or not the notification determination result by the notification determination unit 1d2 is “YES” (step F5).

  In Step F5, when the determination result of the notification availability is not “YES” (Step F5; No), the process proceeds to Step F7, and when the determination result of the notification availability is “YES” (Step F5; Yes), Step F6. Migrate to In step F6, the memo information notification control unit 1d determines that the availability determination result is “YES” (memo information is available), and the notification availability determination result is “YES” (memo information can be notified). Therefore, it is determined that the memo information is notified to the user, and an instruction signal for instructing the mobile terminal 3 to notify the content of the memo information is transmitted to the mobile terminal 3 together with the memo information to be notified. Transmit (step F6).

  After step F6, the memo information notification control unit 1d determines whether or not the processing of steps F1 to F6 has been performed on all the memo information stored in the memo information database 1c, and the memo information database 1c If it is determined that the processing of Step F1 to Step F6 has been performed on all stored memo information (Step F7; Yes), the notification processing of this memo information is terminated, and if it is determined that it has not been performed (Step F7; No), the process proceeds to step F1. As described above, the processing from step F1 to step F6 is performed on all the memo information stored in the memo information database 1c.

  With reference to FIG. 9, the process for determining whether or not to use memo information will be described. First, the availability determination unit 1d1 determines whether the content of the “category” included in the memo information is “music CD”, “DVD”, or “book” (step G1). When the availability determination unit 1d1 determines that the content of the “category” included in the memo information is “music CD”, “DVD”, or “book” (step G1; Yes), The content of “scheduled release date” is acquired, and the current date and time is acquired by the date information acquisition unit 1h (step G4).

  The availability determination unit 1d1 compares the scheduled release date indicated in the “scheduled release date” acquired in step G4 with the current date and time acquired by the date and time information acquisition unit 1h in step G4, and the current date and time is “released”. It is determined whether or not the scheduled release date indicated in “scheduled date” has passed (step G5). When the availability determination unit 1d1 determines that the current date and time has passed the scheduled release date indicated in the “scheduled release date” (step G5; Yes), the availability of the memo information is set to “YES” (the memo information is (Available)) (step G6). If the availability determination unit 1d1 determines that the current date / time has not passed the scheduled release date indicated in the “scheduled release date” (step G5; No), the determination process ends.

  If the availability determination unit 1d1 determines in step G1 that the content of the “category” included in the memo information is not “music CD”, “DVD”, or “book” (step G1; No), It is determined whether or not the content of “category” in the memo information is “restaurant” (step G2). When it is determined in step G2 that the content of the “category” of the memo information is “restaurant” (step G2; Yes), the availability determination unit 1d1 acquires the content of the “opening time zone” of the memo information. The date and time information acquisition unit 1h is made to acquire the current date and time (step G7).

  The availability determination unit 1d1 compares the time zone indicated in the “opening time zone” acquired in step G7 with the current date and time acquired by the date and time information acquisition unit 1h in step G7. It is determined whether or not it is in the time zone indicated in “Time zone” (step G8). If the availability determination unit 1d1 determines in step G8 that the current date and time is in the time zone indicated in the “opening time zone” (step G8; Yes), it is indicated in the “store position” of the memo information. Proximity determination for the position is performed by the proximity determination unit 1f (step G9). If the availability determination unit 1d1 determines in step G8 that the current date and time are not in the time zone indicated in the “opening time zone” (step G8; No), the determination process ends.

  After step G9, the availability determination unit 1d1 determines that the result of the proximity determination by the proximity determination unit 1f is “YES” (the current position of the mobile terminal 3 is close to the position indicated by “Store position”). In step G10, the availability determination unit 1d1 determines that the result of the proximity determination by the proximity determination unit 1f is “YES” (step G10; Yes). The availability is determined as “YES” (note information can be used) (step G11). When the availability determination unit 1d1 determines in step G10 that the result of the proximity determination by the proximity determination unit 1f is not “YES” (step G10; No), the determination process ends.

  When the availability determination unit 1d1 determines in step G2 that the content of the “category” of the memo information is not “restaurant” (step G2; No), the content of the “category” of the memo information is “accommodation facility”. It is determined whether or not there is (step G3). In step G3, when the availability determination unit 1d1 determines that the content of the “category” of the memo information is “accommodation facility” (step G3; Yes), the usage information determination unit 1d1 performs the processing for the position indicated in the “store position” of the memo information. Proximity determination is performed by the proximity determination unit 1f (step G12).

  After step G12, the availability determination unit 1d1 determines that the result of the proximity determination by the proximity determination unit 1f is “YES” (the current position of the mobile terminal 3 is close to the position indicated by “Store position”). It is determined whether or not there is (step G13). In step G13, when the availability determination unit 1d1 determines that the result of the proximity determination by the proximity determination unit 1f is “YES” (step G13; Yes), the availability of the memo information is determined as “YES” (the memo information is used). (Step G14).

  When the availability determination unit 1d1 determines in step G3 that the content of the “category” of the memo information is not “accommodation facility” (step G3; No), or in step G13, the proximity determination unit 1f performs proximity determination. If it determines with a result not being "YES" (step G13; No), this determination process will be complete | finished.

  The proximity determination process will be described with reference to FIG. The processing contents shown in the flowchart of FIG. 10 are the processing contents of Step G9 and Step G12 of the flowchart of FIG. The proximity determination unit 1f acquires the position (latitude / longitude) indicated by the “store position” of the memo information from the availability determination unit 1d1 and the current position (latitude / longitude) of the mobile terminal 3 as the position information acquisition unit 1j. (Step H1).

  After step H1, the proximity determination unit 1f acquires the position (latitude and longitude) acquired from the availability determination unit 1d1 in step H1 and the current position (latitude and longitude) of the mobile terminal 3 acquired by the position information acquisition unit 1j in step H1. ), Whether or not the mobile terminal 3 is within a certain range from the position indicated in “Store position” (for example, in a circular area having a predetermined radius centered on “Store position”). Determine (step H2).

  In step H2, if the proximity determination unit 1f determines that the mobile terminal 3 is within a certain range from the position indicated by the “store position” (step H2; Yes), the mobile terminal 3 indicates the “store position”. It is determined as “YES” indicating that it is close to the position that has been set (step H3), the determination result “YES” is notified to the availability determination unit 1d1, and the mobile terminal 3 indicates “Store position”. If it is determined that it is not within a certain range from the position where it is set (step H2; No), this determination process is terminated.

  With reference to FIG. 11, the process for determining whether or not to notify memo information will be described. The notification availability determination unit 1d2 causes the schedule information acquisition unit 1i to acquire today's schedule information of the user of the mobile terminal 3 from the schedule information database 1k, and causes the date information acquisition unit 1h to acquire the current date and time (step J1). Based on the schedule information of the user of the mobile terminal 3 acquired by the schedule information acquisition unit 1i in step J1 and the current date and time acquired by the date and time information acquisition unit 1h in step J1, the notification availability determination unit 1d2 It is determined whether the user of the mobile terminal 3 is within the scheduled time for work or business trip (step J2).

  In Step J2, if the notification availability determination unit 1d2 determines that the current time is within the scheduled time for the user's work or business trip of the mobile terminal 3 (Step J2; Yes), the notification availability is “NO” (corresponding to the situation of notification). (Step J7), and if it is determined that the current time is not within the scheduled time for the work or business trip of the user of the mobile terminal 3 (Step J2; No), the process proceeds to Step J3. In Step J3, the notification availability determination unit 1d2 is based on the schedule information of the user of the mobile terminal 3 acquired by the schedule information acquisition unit 1i in Step J1 and the current date and time acquired by the date information acquisition unit 1h in Step J1. Thus, it is determined whether or not the present time is within other scheduled time other than work or business trip (for example, within scheduled time such as travel or meal) (step J3).

  In step J3, if the notification availability determination unit 1d2 determines that the current time is within the other scheduled time (step J3; Yes), the notification availability determination unit 1d2 determines that notification availability is “YES” (corresponding to a notification situation) (step J8). ) If it is determined that the current time is not within the other scheduled time (that is, it is not currently within any of the scheduled time of the schedule information acquired in step J1) (step J3; No), the process proceeds to step J4. To do. In step J4, the notification availability determination unit 1d2 informs the status determination unit 1g of the current status of the user of the mobile terminal 3 (“working”, “going to work / going home”, “at home”, or “going out”). Determine (step J4).

  The notification availability determination unit 1d2 determines whether the current status of the user of the mobile terminal 3 determined by the status determination unit 1g is “working” or “at home” (step J5). When it is determined that the current status of the user of the mobile terminal 3 is not “working” or “at home” (step J5; No), the notification availability determination unit 1d2 determines the notification availability as “YES” (step J9) If it is determined that the current status of the user of the mobile terminal 3 is either “working” or “at home” (step J5; Yes), the notification availability is determined as “NO”.

  The situation determination process will be described with reference to FIG. The process shown in the flowchart of FIG. 12 is the process of step J4 in the flowchart of FIG. First, the situation determination unit 1g causes the date and time information acquisition unit 1h to acquire the current date and time, causes the position information acquisition unit 1j to acquire the current position of the mobile terminal 3, and the work location of the user of the mobile terminal 3 (work location) And the home position are acquired from the built-in memory (such as the RAM 13 and the recording device 15) of the memo information management server 1 (step K1).

  Whether the current date and time acquired by the date and time information acquisition unit 1h in step K1 is in the time zone of weekdays (from Monday to Friday) and during the daytime (for example, from 6:00 am to 8:00 pm) (Step K2), and if it is determined that the current date and time is in the weekday (from Monday to Friday) and in the daytime (for example, from 6:00 am to 8:00 pm) (step K2; Yes), the process proceeds to step K5, and if it is determined that the current date and time is not a weekday (from Monday to Friday) and not in the daytime (for example, from 6 am to 8 pm) (step K2; No) ), And proceeds to step K3.

  In step K5, the situation determination unit 1g determines that the current position of the mobile terminal 3 acquired by the position information acquisition unit 1j in step K1 is within a certain range from the work location of the user of the mobile terminal 3 acquired in step K1 (for example, Then, it is determined whether or not it is in a circular area having a predetermined radius centered on the office building (step K5).

  When the situation determination unit 1g determines that the current position of the mobile terminal 3 acquired by the position information acquisition unit 1j in step K1 is within a certain range from the work position of the user of the mobile terminal 3 acquired in step K1 (step S1). K5; Yes), the situation of the user of the mobile terminal 3 is determined as “working” (step K6), and the current position of the mobile terminal 3 acquired by the position information acquisition unit 1j in step K1 is acquired in step K1. If it is determined that it is not within a certain range from the work location of the user of the terminal 3 (step K5; No), the status of the user of the mobile terminal 3 is determined as “going to work / going home” (step K7).

  In step K3, the situation determination unit 1g determines that the current position of the mobile terminal 3 acquired by the position information acquisition unit 1j in step K1 is within a certain range from the home position of the user of the mobile terminal 3 acquired in step K1 (for example, It is determined whether or not it is within a circular area having a predetermined radius centered on the home (step K3).

  When the situation determination unit 1g determines that the current position of the mobile terminal 3 acquired by the position information acquisition unit 1j in step K1 is within a certain range from the home position of the user of the mobile terminal 3 acquired in step K1 (step K3 Yes), the situation of the user of the mobile terminal 3 is determined to be “at home” (step K8), and the mobile terminal 3 that the current position of the mobile terminal 3 acquired by the position information acquisition unit 1j in step K1 is acquired in step K1. If it is determined that it is not within a certain range from the user's home position (step K3; No), the user status of the mobile terminal 3 is determined to be “going out” (step K4).

  Next, the effect of the memo information management server 1 will be described. The memo information management server 1 manages memo information transmitted from the mobile terminal 3. The memo information management server 1 includes a memo information database 1c and a schedule information database 1k. The memo information database 1c stores memo information (for example, memo information D1) transmitted from the mobile terminal 3. The schedule information database 1k stores schedule information (for example, schedule information D2) of the user of the mobile terminal 3.

  In addition, the memo information management server 1 includes an availability determination unit 1d1, a notification availability determination unit 1d2, and a communication unit 1a. The availability determination unit 1d1 acquires usage conditions (for example, planned release date, opening hours, store location, etc.) of the memo information from the memo information stored in the memo information database 1c, and based on the acquired usage conditions. To determine whether the memo information can be used.

  The notification availability determination unit 1d2 indicates status information indicating the current status of the user of the mobile terminal 3 based on the schedule information of the user of the mobile terminal 3 (for example, information indicating work, business trip, going to work / going home, staying home, going out, etc.) ), And based on the acquired status information, it is determined whether or not the mobile terminal 3 is to be notified of the contents of the memo information determined to be usable by the availability determining unit 1d1. When the communication unit 1a informs the mobile terminal 3 of the memo information determined to be usable by the use determination unit 1d1, the communication unit 1a receives a signal instructing to notify the memo information when determined by the notification determination unit 1d2. It is transmitted to the mobile terminal 3 together with the memo information.

  According to the memo information management server 1 according to this embodiment, the user of the mobile terminal 3 does not directly operate the mobile terminal 3 to browse the content of the memo information, but is suitable for browsing according to the content of the memo information. (For example, when you approach the “store” included in the memo information, or when you return home, or when a special date such as the planned release date arrives, etc.) Since it is displayed on the display device of the terminal 3, even if the user of the mobile terminal 3 is not aware of the necessity of browsing the memo information (for example, the user of the mobile terminal 3 forgets the content of the memo information Even in the event of a failure, the memo information can be used.

  The memo information management server 1 further includes a memo information update unit 1e. The memo information update unit 1e acquires meta information used to update the memo information stored in the memo information database 1c from the meta information server 5, and updates the memo information using the acquired meta information. The memo information update unit 1e is based on the contents of the memo information to be updated and the schedule information stored in the schedule information database (for example, the planned release date included in the memo information, the information source of the memo information) Specific update date, the number of days elapsed since the last update date, tomorrow's schedule included in the schedule information, etc.), and the update date (whether today is the update date) of the memo information The memo information is updated using the meta information according to the updated date.

  According to the memo information management server 1 according to the present embodiment, the memo information stored in the memo information database 1c of the memo information management server 1 is updated to the latest information at a suitable frequency and timing according to the content of the memo information. Since it becomes possible, the overload to the meta information server 5 by acquiring information more frequently than necessary can be suppressed.

  Conventionally, when browsing memo contents, some browsing operation has to be performed.For this reason, for example, in the case of memo contents related to the purchase of books, even if the user passes near a store where purchase is possible, If the user is not aware of “Look at the memo”, the contents of the memo are not viewed, and the user may forget to purchase the book. On the other hand, if the memo information management server 1 according to the present embodiment is used, information suitable for the user can be provided to the user at an appropriate timing. Although you are not in a situation where you can perform an action such as purchasing, you want to keep a record of the product you want to purchase (input memo information) for the time being. It is enough to meet the needs of users who want to be able to refer to the latest content.
