Description

  The present invention relates to an information recall search system, an information recall search apparatus, an information recall method, a program, and a recording medium, and more specifically, to realize a reminder function that recalls what has been conceived or must not be forgotten. It is about technology.

  Thinking about something at work or in life is not necessarily about what you are working on at the time. You can think of it in various situations, such as when you are at work, walking, on the train, relaxing at home, cleaning, or talking to people.

In such a situation, when managing the occurrence and progress of schedules or organizing ideas, many people record them in a notebook or memo pad and refer to them later.
However, after writing down and organizing all of your schedules and ideas, you can use them reliably, but you may get them and leave them without taking notes, and you may not be able to remember the contents later. Also, I took a note, but I lost the note or forgot the existence of the note. For example, “What was the idea that came up during cleaning yesterday?”, “When I met Mr. A There are many things that end without remembering what you should not forget, even if you remember the situation.

  In order to support such a situation, there is a personal information management system known as PIM (Personal Information Manager) or PDA (Personal Digital Assistant). In this personal information management system, what to do for what, such as schedule management to create and manage schedules such as monthly schedule, weekly schedule, daily schedule, etc. Personal information management functions such as ToDo management for setting and managing work items and address book management for creating and managing address books are incorporated.

  However, work items that should not be forgotten such as what you need to tell someone or want to ask someone can be entered to some extent in the personal information management system as described above, but the title and contents are written in text. Since the input is common, in the personal information management system, it is never easy to use anywhere anytime while walking or on the train, considering the trouble of inputting information and the ease of use of information. It is not enough, and in the end, many people use notebooks and notepads.

Also, I want to record what I came up with in the process of thinking about my work, without leaking it for later organization. The contents of such ideas may be drafts of ideas that cannot be expressed in text, or they may be in a hazy state that needs to be clarified but is not yet materialized. Since there is not enough time to convert to text, we are currently drawing diagrams with PDAs and recording contents with voice on IC recorders.
However, each record is just fragmentary information and is recorded only as a file, so people must remember what they recorded and voluntarily refer to the contents of this file as necessary. It cannot be used.

On the other hand, in order to remember what has come up in the past and what needs to be done in the past, people are reminded of the contents from the situation when they came up. Or if you know what you need to do, but don't know what the group is, you can recall the group from the resulting situation.
As a technique for supporting such memories, there is a technique of Patent Document 1.

  The technology of Patent Literature 1 includes an agent, a database, and a means for communicating with another object in each object (terminal, device, machine, etc. carried by a person). The agent records the fact (time, target, target attribute, meaning of attribute) when communicating with another target through the communication means in the database of the target to which the agent belongs. For example, if two objects are at the same location, each agent communicates and records the facts in each database. When searching for past facts, the database is searched by designating a part of the facts.

On the other hand, there is a technique of Patent Document 2 or Patent Document 3 for a request to remember a content that has been conceived when necessary (a reminder).
In the technique of Patent Document 2, an information ID (eg, AA town B-chome C, bookstore) transmitted from a small antenna station at an installation location, and information in a memory of a reminder device approaching the installation location (eg: AA) When a match is made with Machi B Chome, bookstore), an alarm sound is generated, and a free message (“Here is AA Mcho B C”, “There is a bookstore”) is displayed on the display means, and the result The user who carries the reminder device can awaken the input message.

Further, in the technique of Patent Document 3, the current position acquired is compared with the stored setting point, and when it is determined that the current position has approached the setting point, the stored memo information is displayed. In addition, light, sound, vibration, etc. are generated to notify the approach. Thereby, when approaching the set point, the user can be notified and the user can be surely reminded of the work item.

In the following description, an information recall system built on a company network will be described as an example.

FIG. 3 is a block diagram showing a functional configuration of the information recall search server and the information recall search client of the information recall search system according to the first embodiment. In the figure, an information recall server 100 includes an information management means 110, an information search means 120, a situation search means 130, an information storage database (hereinafter abbreviated as DB) 140, a recall means 150, a recall management means 160, The time acquisition means 170, the reception means 180, and the transmission means 190 are comprised.
The information retrieval search client 200 includes an input unit 210, a display unit 220, a notification unit 230, a transmission unit 240, and a reception unit 250.

First, the information storage DB 140 will be described.
The information storage DB 140 is a database that stores the content that has been conceived, the situation when it comes to mind, the situation that should be remembered, and the like each time it comes to mind, and is composed of the data items illustrated in FIG. Among these data items, “partner”, “location”, “action”, and “priority” are selected from preset items. However, if there are no appropriate items in the options, a new additional item can be set, and from the next time, an option including the added item will be selected.

(A) Information-related items:
Title: The title of the information that came up.
Type: A storage format for information that has been conceived, indicating whether the format is text, audio, image, video, or the like. This type is determined by the type of device when the information is input, and when it is output, the output device is determined by this type.
Content: The content of the information that has been conceived and may be stored directly in the information storage DB, but may be a URI (Uniform Resource Identifier) storing the content of the information.

(B) The situation when you came up (current):
Date and time: Memorize the date and time when you came up.
Opponent: A list of people who were with you when you came up.
Location: Select the location where you were when you came up from the options (company, train, desk (self-seat), conference room, auditorium, etc.).
Action: Select what you were doing when you came up with from options (for example, during work, during commuting, meetings, meetings, etc.).

(C) Situations to remember:
Date and time: The content to remember is the date and time of the expiration date. Information that has passed this date and time may not be deleted until the user instructs to delete it, or information that has passed a certain date and time after this date and time is deleted. May be.
Opponent: A list of names of reminders of information that was recalled.
Location: Select the presentation location for the remembered information from the choices (conference room, auditorium, etc.).
Action: Choose what to do when you remember.

(D) Priority: The importance of the information that has come up. This importance corresponds to the frequency of notification by recall, and the higher the importance, the more frequently the notification is made. In addition, a recall period can be set, and information in which this recall period is set is notified only within this period. For example, in the case of a high priority such as “A”, notification is made once a day, and in the case of a medium priority such as “B”, notification is made at a rate of once every three days. In the case of a low priority such as “C”, notification is made at a rate of once per week.

(E) Last recall time:
It is set when recalling by priority, and recall data is notified when the date and time and the current date and time exceed the time interval specified by the priority. The initial value of the last recall date is zero.

(F) Deletion deadline:
It is set when a deletion deadline is designated by the “deletion function” from the user, and information that has passed this time is deleted from the information storage DB 140. The initial value of the deletion deadline is “not specified”.

  For example, when “Meeting” is held in “Meeting room A” and “Meeting person A”, “Meeting room” comes up with a “new plan” and “reports” at “planning meeting” one week later. Is set as follows.

(A) Information-related items:
Title: “Plan for ...”,
Type: “Voice”
Contents: URI of the audio file containing the plan.
(B) The situation when you came up (current):
Date and time: The date and time when you came up,
Partner: “Mr. A, Mr. B, himself”
Place: “Conference Room A”
Action: “Meeting”.
(C) Situations to remember:
The date and time: One week after the date and time of thinking (today)
Partner: the person,
Location: Undecided, not set
Action: “Explanation of the plan”.

Next, an operation for accumulating information that the user has come up with will be described.
The user activates the input means 210 of the information recalling search client 200 and inputs information that has come to mind. The operation of the input unit 210 will be described with reference to the flowchart of FIG.

First, when an operation for inputting information that has been conceived is performed, for example, an input screen as shown in FIG. 6 is displayed, and the content of the information that has been conceived and its title are input (step S1). Here, the title does not need to be input, but when it is input, it is input as a character string.
The content of the information that has been conceived may be any of a character string, sound, image, video, etc., but is taken into the information recall client 200 in a form that depends on the input device. In order to input the contents, it is captured by pressing an input icon displayed on the input screen. For example, for the “text” icon, the text editor is activated and a character string indicating the content is input. The “file” icon is used when a character string, sound, image, video, or the like has already been created. For example, a file transfer from a recording device such as an IC recorder to the information recall client 200 is performed. Captured in form.
Also, the type of information is determined by the type of the input device. For example, when inputting information from a keyboard, the type is “character”, when inputting from a microphone or IC recorder, the type is “speech”, and when inputting from a scanner, graphic input pad, etc., the type is “image”. When the input is from a video camera, the type is determined as “video” or the like.

Next, the situation (date, place, action, partner) to be remembered is input (step S2).
Each item of the situation is set by selecting from the set options, but it is not necessary to select and input all at once. The necessary items are input, registered once in the information storage DB 140, and edited. Insufficient information may be added.
Further, when the “date and time” is not input, the importance level of the information that has come up and the recall period of the recall notification may be designated.
Also, if there is no appropriate item in the options, a new option can be additionally set.

  Next, in the same way as the above-mentioned situation that should be remembered, the situation (partner, place, action, date and time) at the time of coming up is selected and input (step S3). Here, “date and time” displays the current time, but the user can also change it.

When the above-mentioned information input of the idea ends, for example, when the registration button is pressed, the information recall client 200 transmits the title of the input information, the content, the type of the content, the situation at the time of coming up, and the situation to be remembered. Pass to means 240.
The transmission means 240 transmits the passed information to the information recall server 100 as a registration request.

Next, the information recall server 100 receives the registration request transmitted from the information recall client 200 by the receiving unit 180.
When receiving the registration request, the receiving unit 180 activates the information management unit 110 and passes the received registration request, and the information management unit 110 registers the received information as new information in the information storage DB 140.
Here, when registration is completed when successful, a message to that effect is sent, and when registration is unsuccessful, a message to the effect that registration is not possible is sent via the transmission means 190 to the information recalling search client 200. You may make it transmit to.

In the above input means 210, the situation at the time of coming up was input by selecting from the set options, but the situation similar to the present is extracted from past data and added to the options You may make it display.
In this case, the input unit 210 inquires of the information recall server 100 about a selection item when displaying a choice of “situation when the user comes up”.

In response to this inquiry, the information retrieval server 100 activates the situation retrieval means 130, searches the information storage DB 140 based on the current day and time, and obtains a situation (location, location, Action) and returns this situation to the input means 210 of the information recall client.
For example, if the current day of the week is Tuesday and the time is 9:00 am, the information storage DB 140 is searched under the search condition “day of week is Tuesday, time is 9:00 am (30 minutes before and after)”. As a result of the search, if the items of “Location” are “Company” and “Train”, “Behavior” is “Working”, “Commuting” and “Meeting” as high-frequency situations, Are extracted as selection items.

  The input means 210 displays a new option in which the received situation (location, action) is inserted at the head of the option, and the user selects the current situation, and if there is no appropriate option, the current option is displayed. Enter the status.

  The information that should be recorded often comes from the time that is not registered in the daily schedule, but the same time on the same day of the week often does the same thing. The input burden can be reduced by effectively using.

Next, a case where the user finds information that has come up in the past will be described.
The user activates the input unit 210 of the information retrieval search client 200 and inputs a part or all of the situation when he / she comes up or the situation to be remembered as a search condition. Here, the search condition may be input by the user, or each situation extracted using the situation search means 130 described above may be displayed as an option.
When the input of the search condition is completed, the input unit 210 transmits the input search request to the information recall search server 100 via the transmission unit 240.

The information recall server 100 receives a search request from the information recall search client 200 by the receiving unit 180, starts the information search unit 120, and passes the received search request.
The information search means 120 searches the information storage DB 140 with the received search condition, and sends the information that matches the search condition and the situation accompanying the information as a search result to the information recall search client 200 via the transmission means 190. Send back.

The information retrieval search client 200 receives the returned search result by the receiving means 250, activates the display means 220, and passes this search result.
The display means 220 displays the search results as a list. At this time, if there is an input title or situation, it is displayed in the list, and the information storage format (character string, audio, video, etc.) is displayed with a type icon or the like.

For example, when searching for information conceived in the “conference room”, for example, a search result as shown in FIG. 7 is displayed. The first line in FIG. 7 shows search conditions, and the second and subsequent lines represent search results.
The search results indicate “date and time”, “title”, “information storage format icon”, and “partner” when they come up.
Among these, the “information storage format icon” is an icon representing an information storage format (for example, text, sound, image, video, etc.), and the contents of the information are displayed by executing this icon.
The user executes the icon of the information he / she is looking for from the displayed search results, and outputs the information to a display device or a speaker to extract the contents.

Next, the memory activation work that prompts the user to recall will be described.
The recall management unit 160 of the information recall search server 100 operates at a recall processing time interval set in advance, and notifies the user of information retrieved at (1) the date and time and (2) the priority.

(1) Timing by Date and Time The operation of the recall management means 160 when recalling at the timing by date and time will be described using the flowchart of FIG.
When the preset recall processing time interval is reached, the recall management unit 160 starts operating, and the recall management unit 160 acquires the current date from the time acquisition unit 170 and uses this date as a search condition (step S11). .
The information search means 120 is activated under this search condition, and the information storage DB 140 is referenced to obtain the information that matches the “date and time” of the situation to be remembered and the date of the search condition (step S12).
If there is no search result (NO in step S14), the process is terminated.
On the other hand, if there is a search result (YES in step S14), the search result is transferred to the recalling means 150, converted into a format suitable for notification by referring to the type of information (step S15), and the converted notification information Is transmitted to the information recall client 200 via the transmission means 190 (step S16), and the process is terminated. The notification here is notified by any one or combination of the following.
• Sound an alarm or beep.
-Display / reproduce the title and contents of information on the display device.
・ Play information content from speakers.
・ Send information as an email.

  The information recall client 200 passes the notification information received by the reception unit 250 to the notification unit 230. The notification unit 230 generates an alarm or a beep according to the format of the notification information, and displays / displays the title and contents of the information on the display. The user is notified that there is information by playing it, playing the information content from the speaker, or sending the information content as an e-mail.

  In this way, it is possible to use information registered in the database as a reminder by checking whether there is a situation to be remembered in the information storage DB 140 and notifying the user if this is the case.

(2) Timing by Priority The operation of the recall management means 160 when recalling at the timing by priority will be described using the flowchart of FIG.
When the preset recall processing time interval is reached, the recall manager 160 starts operating, and the recall manager 160 takes out one priority from the preset priority list (step S21).
If there is an extracted priority (YES in step S22), the recall timing corresponding to this priority is extracted (step S23).
For example, as shown in FIG. 10, the recall timing represents the frequency of recall corresponding to the priority. For example, when the priority is “A”, the recall timing is daily. Is set in advance to notify the recall data every 3 days, and in the case of “C” every 4 days.
There is a lot of information that has to be processed, although the deadline is not fixed, and such information is initially abstract and becomes increasingly specific. In order to support this process, it is possible to make a recall according to the priority of the contents by changing the recall timing.

Next, the current date and time are acquired from the time acquisition means 170, and the current date and time, the recall timing and the priority are set as search conditions (step S24).
The information search unit 120 refers to the information storage DB 140 and acquires information having the same priority and a difference between the current date and time and the previous recall date and time that is equal to or greater than the recall timing (step S25).
If a recall period is set in the acquired information (YES in step S26) and the current date and time is within the recall period (YES in step S27), or if a recall period is not set in the acquired information ( In step S26 NO), the information storage DB 140 is updated by replacing the previous recall date and time with the current date and time, and the search result is temporarily stored in the storage device (step S28). Search for priority.
If the current date and time is not included in the recall period of the acquired information (NO in step S27), the acquired information is set as information not to be recalled, and the process returns to step S21 to search for the next priority.

  On the other hand, when there is no priority to be processed in the priority list (NO in step S22), the search result temporarily stored in the storage device is transferred to the recalling means 150 and notified by referring to the type of information. (Step S29), the converted notification information is transmitted to the information recall client 200 via the transmission means 190 (step S30), and the process is terminated.

Next, editing of registered contents in the information storage DB 140 and deletion of data will be described.
In order to additionally edit or delete the registered contents of the information storage DB 140, first, when the search result information or recall information is displayed, the contents are additionally edited or deleted according to the user's instruction. This additional editing can also be used when only a part of the data is registered when registering the information that has come up.

After the information is displayed on the display device by the display means 220 as a result of the search or notification by recall, when the “additional editing” function is selected on this display screen, the input means 210 of the information recall search client 200 The additional editing screen is displayed on the display device.
The user adds or changes the situation when he / she comes up, the situation to be remembered, the title, etc. from this additional editing screen. Also, if there is a change in the information content itself, if the information is represented by a character string, the information is corrected, added, or deleted for the character string. In other cases (for example, audio, video, image, etc.), information is captured as a whole.
The input unit 210 transmits the input edit information as an edit request to the information recall server 100 via the transmission unit 240.
In the information recall server 100, the editing request received by the receiving unit 180 is passed to the information management unit 110, and the information recorded in the information storage DB 140 is updated.

In this way, even if all information is not available, it can be registered easily, and it can be recalled later, edited in an environment that is easy to edit, such as a keyboard, and corrected to information that is easy to use.
For example, while audio and video information are easy to create, they are difficult to use later, so it is possible to add a title to such information or convert it to text.

On the other hand, information once registered in the information storage DB 140 is deleted as follows.
After a search result or a reminder notification is displayed on the display device by the display means 220, a “delete” operation is performed from a button, menu, or the like, and an expiration date until the deletion is instructed. The means 210 transmits the identifier for identifying the information to be deleted and the time limit until the deletion as a deletion request to the information recall server 100 via the transmission means 240.

In the information recall server 100, the deletion request received by the receiving unit 180 is transferred to the information management unit 110, and the information storage DB 140 is updated by replacing the deletion deadline corresponding to the designated information with the received deletion deadline.
Further, the information management unit 110 operates at a preset interval, and deletes information whose time limit has expired from the information storage DB 140. Moreover, it may be deleted when a certain period of time has passed after the time registered in “Date and time” in the situation to be remembered, and the user is inquired whether or not to delete, and the deletion instruction Only when it is issued, the information may be completely deleted from the information storage DB 140.

  As described above, since the information deletion function is provided, the capacity of the information storage DB can be kept to the minimum necessary.

By constructing the first embodiment as described above, it is possible to use any media, a diagram that shows only the thought process, a handwritten memo, a spoken voice, or a video. Since it can be easily recorded as a memorandum with little effort, it can be prevented from forgetting anyway.
In addition, when recalling the content of information that has come up, it is possible to search based on the situation at the time of coming up or the situation that should be remembered.
Furthermore, if the date and priority of the situation to be remembered is specified, the user is notified according to the progress, so it can also be used as a reminder.

<Embodiment 2>
In the second embodiment, the schedule information of the schedule management system is used in the first embodiment described above.
FIG. 11 is a block diagram showing functional configurations of the information recall system and schedule management system according to the second embodiment. In the figure, an information recall client 200 and a schedule system client 400 can operate on a client computer 500 used by a user, and this client computer 500 is connected to a network (intranet, home LAN, Internet, etc.). ), The information recall server 100 and the schedule system server 300 on which the schedule management system operates are connected.

The information retrieval server 100 includes an information management unit 110, an information retrieval unit 120, a situation retrieval unit 130, an information storage DB 140, a recall unit 150, a recall management unit 160, a schedule data acquisition unit 165, a time acquisition unit 170, a reception unit 180, The transmission means 190 is comprised.
The information retrieval search client 200 includes an input unit 210, a display unit 220, a notification unit 230, a transmission unit 240, a reception unit 250, and a schedule data acquisition unit 260.
Here, in FIG. 11, the same functions as those in FIG. 3 are denoted by the same reference numerals, and only the differences will be described.

The schedule data acquisition means 260 of the information recall client 200 is connected to the schedule system server 300 via the schedule system client 400 operating in the client computer 500 to acquire schedule data.
The schedule data acquisition unit 165 of the information recall server 100 is connected to the schedule system server 300 to acquire schedule data.

  In the second embodiment, the schedule management system is operated by the schedule system server 300 connected via the network. However, the schedule management system may be operated in the client computer 500 as a matter of course. In this case, the schedule data acquisition unit 260 connects to the schedule management system in the client computer 500 and acquires the schedule data.

When registering information that has come up with the input means 210 of the second embodiment, the input of information title, content, and the situation to be remembered is the same as in the first embodiment, but when inputting the situation when it comes to mind. It works as follows.
In order to input the current status, the user performs an operation of “obtaining the current status from the schedule management system”, for example, pressing a button or selecting a menu.

  The input unit 210 acquires the current date and time by this operation, and passes this date and time to the schedule data acquisition unit 260. The schedule data acquisition unit 260 is connected to the schedule system server 300 via the schedule system client 400 to acquire schedule data within a certain time (for example, 1 hour) before and after the specified current date and time, and to the input unit 210 return.

  For example, in the schedule management system, when the schedule is registered in advance as shown in FIG. 12, the information recalling client 200 inputs information that came up at “10:00 on April 1, 2004”. , When “Get Current Status from Schedule” operation is performed, the options for the current status are “Lecture Hall”, “A Conference Room” as “Location”, “Morning”, “Meeting” ”And“ Mr. aa ”and“ Mr. bb ”are obtained as“ the other party ”.

  In the input means 210, when the schedule data is obtained, it is automatically set as the current situation, and is automatically set as the above-described information title, content, content type, and the situation to be remembered. The situation when the user remembers is transmitted to the information recall server 100 via the transmission means 240 and recorded in the information storage DB 140.

  In the above description, the schedule data obtained by the schedule data acquisition means 260 is automatically set as the current situation that has been conceived. However, the obtained data is displayed as an option, and the user can select an appropriate one from this option. It may be configured to select the correct one or to input the situation if there is no appropriate one.

Next, recall by schedule linkage will be described.
FIG. 13 is a flowchart for explaining the operation of the recall management means 160 when recalling based on the schedule managed by the schedule management system.
When the preset recall processing time interval is reached, the recall management unit 160 starts operating, and the recall management unit 160 acquires the current date from the time acquisition unit 170, and uses this date as a search condition (step S31). This search condition is passed to the schedule data acquisition means 165 to acquire schedule data related to the passed date (step S32).
If there is no schedule data related to the current date (NO in step S33), the process ends.

On the other hand, if there is schedule data (YES in step S33), the information on “location”, “action”, and “partner” included in the schedule data is passed to the information search means 120 as a search condition, and the information search means 120 searches for the “situation that should be remembered” in the information storage DB 140 using this search condition (step S34).
If there is no search result (NO in step S35), the process is terminated.
On the other hand, if there is a search result (YES in step S35), the search result is transferred to the recalling means 150, converted into a format suitable for notification by referring to the type of information (step S36), and converted notification information Is transmitted to the information retrieval search client 200 via the transmission means 190 (step S37), and the process ends.

  As in the first embodiment, the information recall client 200 passes the notification information received by the receiving unit 250 to the notification unit 230. The notification unit 230 generates an alarm or a beep sound or displays information on the display depending on the format of the notification information. The user is notified that there is information by displaying / reproducing the title and content, reproducing the information content from the speaker, and transmitting the information content as an e-mail.

By configuring the second embodiment as described above, the situation (partner, location, action) of the date and time that has been conceived can be obtained from the schedule management system, so the input burden on the user is reduced.
In addition, it is possible to notify the user of “situations that should be remembered” related to a partner, a place, and an action included in the schedule registered in the schedule management system.

<Embodiment 3>
In the first embodiment and the second embodiment described above, the information recall system that a user uses alone has been described. In the third embodiment, a case where a plurality of users share one information retrieval search system will be described.
In the third embodiment, a case in which the second embodiment is shared by a plurality of users will be described, but the same applies to the first embodiment.

FIG. 14 is a block diagram showing functional configurations of the information recall system and schedule management system according to the third embodiment. In the figure, a plurality of client computers 500, an information recall server 100, and a schedule system server 300 are connected by a network (intranet, home LAN, Internet, etc.).
Here, the client computer 500 and the schedule system server 300 have the same configuration as that of the second embodiment in FIG.

  The information recall server 100 includes an information management unit 110, an information search unit 120, a situation search unit 130, an information storage DB 140, a recall unit 150, a recall management unit 160, a schedule data acquisition unit 165, a time acquisition unit 170, a reception unit. 180, transmission means 190, user management means 115, and user DB 125. In FIG. 14, the same functions as those in FIGS. 3 and 11 are denoted by the same reference numerals, and only differences will be described.

The user DB 125 is a database of information about users who use the information recall search system, and for each user, a user ID, a user name, a user contact information (e-mail address, IP address, telephone number, etc.). Is recorded.
The user management unit 115 refers to the user DB 125 and returns a user list including user names and user IDs of all users of the system. In addition, referring to the user DB 125, the user name and contact information (mail address) of the user indicated by the user ID are returned to the inquiry source.

  In addition to the data items shown in FIG. 4, for example, as shown in FIG. 15, the information storage DB 140 directly receives the user ID for identifying the user and the “partner” in the situation to be remembered. A flag indicating whether or not to recall is added. Further, when there are a plurality of “partners” in a situation to be remembered, when all of the “partners” are recalled when this flag is ON (indicated by “◯” in FIG. 15), they may be recalled directly. Alternatively, a flag may be prepared for each of a plurality of “partners” so that the recall target can be individually designated.

  Next, an operation in the case of directly recalling the registered partner as the “situation to be remembered” will be described. First, the operation when accumulating information that the user has come up with will be described using the flowchart shown in FIG.

The user activates the input unit 210 of the information retrieval search client 200 and inputs the title of the information that has come up as in the first embodiment (step S41).
What is input here is the content of the information that came up and its title, and the type of information is determined by the type of device that has input the information.
Next, in the same manner as in the first embodiment, a situation to be remembered (date and time, place, action, partner) and priority are input by selecting from respective options (step S42).
Next, in the same manner as in the first embodiment, the situation (date / time, place, action, partner) at the time of coming up is selected and input (step S43).

  The input unit 210 queries the information recall server 100 for a list of users who can use the system, and the user management unit 115 generates a user list of the system from the user DB 125 and returns it to the query source (step) S44).

The user selects an arbitrary number of users from the user list as “partners” in a situation to be remembered (step S45).
Here, when recalling directly to all “partners” in a situation to be remembered, after selecting all “partners”, “whether to directly recall the other party” is selected once.
In addition, when there are multiple “partners” in the situation to be remembered and when setting whether or not to directly recall each individual user, “whether or not to recall directly” when selecting a user. Make selections at the same time.

  For example, when the input of the information that has been conceived ends when the registration button is pressed, the user ID of the user who is performing the operation, the title of the input information, the content, the type of content, the situation at the time of coming up, The situation to be remembered and a flag indicating whether or not to recall directly are transmitted as registration requests to the information recall server 100 via the transmission means 240 (step S46).

The information recall server 100 receives the registration request transmitted from the information recall client 200 by the receiving unit 180, activates the information management unit 110, and passes the received registration request.
The information management unit 110 registers each piece of information of the received registration request as new information in the information storage DB 140 so that the user of the information that has come up with the information can be understood.

Next, recall to the user and recall to the other party will be described.
As described in the first and second embodiments, the recall management unit 160 operates at a preset recall processing time interval, and (1) timing based on date and time, (2) timing based on priority, and (3) schedule. A search is performed at the timing based on the data, and information that matches the conditions is passed to the recalling means 150.

When the information includes “recollection of the other party” as an attribute, the recalling unit 150 extracts the user ID of the “partner” from the situation to be remembered and passes it to the user management unit 115.
The user management means 115 refers to the user DB 125, extracts the user name and contact address corresponding to the user ID, and returns them to the recall means 150.
The recalling means 150 transmits information not only to the user who has come up with the information but also to the contact information of the user registered as the “partner”.
The user who receives the notification from the information recall server 100 is notified of the received content by the notification means 230 and recalls that there is information to be remembered.

  By configuring the third embodiment as described above, the user who recorded the information can be reminded directly to the other party instead of being reminded, so the user forgets to convey it. The human error is reduced once, and the same effect is obtained as requesting something by e-mail or registering information in the other party's schedule.

<Embodiment 4>
Although the information recall system according to the first and second embodiments is configured as a server / client system, it can also be realized by a dedicated device, a single computer, a PDA, a mobile phone, or the like.
Further, when utilizing schedule data of the schedule management system as in the second embodiment, (1) when implemented as an apparatus including the schedule management system itself, and (2) schedule data of the schedule management system via the network. May be used.
In the following description, the fourth embodiment will be described on the assumption that the information recall search system and the schedule management system operate on a single device.

  FIG. 17 is a block diagram illustrating a functional configuration of an information recall search system (information recall search apparatus) and a schedule management system according to the fourth embodiment. In the figure, an information recall search device 100 includes an information management means 110, an information search means 120, a situation search means 130, an information storage DB 140, a recall means 150, a recall management means 160, a time acquisition means 170, a schedule data acquisition means 165, It comprises an input means 210, a display means 220, and a notification means 230. Here, the same reference numerals are given to the same functions in FIG. 17 as those in FIGS. 3 and 11, and only the differences will be described.

First, the operation of accumulating information that the user has come up with will be described.
The user activates the input means 210, and comes up with the title and content of information (character string, sound, image, video, etc.), the situation to remember (date, place, action, partner), and the situation when he / she comes up (Date, place, action, partner) are selected by selecting from the set options. These items do not need to be selected and input all at once, but necessary items may be input, and once registered in the information storage DB 140, the missing information may be added by editing.
When the input is completed by pressing the registration button, the title, content, type of content, situation at the time of coming up, situation to be remembered are passed to the information management means 110.
The information management unit 110 registers the received information as new information in the information storage DB 140.

In the above input means 210, the situation at the time of coming up was input by selecting from the set options, but the situation similar to the present is extracted from past data and added to the options You may make it display.
In this case, the input unit 210 activates the situation search unit 130 to search the information storage DB 140 based on the current day of the week and time when the user displays an option of “situation when coming up”, Obtain a high-frequency situation (location, action) on the same day and time, and use this situation as an option.

Also, the following may be used when inputting the situation when it comes up.
In order to input the current status, the user performs an operation of “obtaining the current status from the schedule management system”, for example, pressing a button or selecting a menu.
This operation acquires the current date and time, and passes this date and time to the schedule data acquisition unit 260. The schedule data acquisition unit 260 acquires schedule data within a certain time before and after the specified current date and time (for example, 1 hour) from the schedule management system 300 and returns the schedule data to the input unit 210.

In the input unit 210, when the schedule data is obtained, the schedule data is automatically set as the current situation and passed to the information management unit 110.
The information management unit 110 records in the information storage DB 140 the above-described information title, content, content type, situation that should be remembered, and the automatically recalled situation.
In the above description, the schedule data obtained by the schedule data acquisition means 260 is automatically set as the current situation, but the obtained data is displayed as an option, and the user can select an appropriate one from this option. It may be configured to select a thing or to enter a situation if no suitable one is available.

Next, a case where the user searches for information that has come up in the past will be described.
The user activates the input unit 210, inputs part or all of the situation when he / she came up or the situation to be remembered as a search condition, and passes it to the information search unit 120. Here, the search condition may be input by the user, or each situation extracted using the situation search means 130 described above may be displayed as an option.
The information search unit 120 searches the information storage DB 140 with the received search condition and passes the search result to the display unit 220 together with the information that matches the search condition and the situation accompanying the information.

The display means 220 displays the search results as a list. At this time, if there is an input title or situation, it is displayed in the list, and the information storage format (character string, audio, video, etc.) is displayed with a type icon or the like.
The user executes the icon of the information he / she is looking for from the displayed search results, and outputs the information to a display device or a speaker to extract the contents.

Next, the memory activation work that prompts the user to recall will be described.
The recall management unit 160 operates at a preset recall processing time interval, and notifies the user of the information retrieved at (1) the timing based on the date, (2) the timing based on the priority, and (3) the timing based on the schedule data. .

(1) Timing by date and time The current date is acquired from the time acquisition unit 170, and this date is passed to the information search unit 120 as a search condition. The information search unit 120 should remember each information with reference to the information storage DB 140. A situation where the “date and time” of the situation matches the date of the search condition is acquired and passed to the recalling means 150.

(2) Timing by priority level One priority level is extracted from a list of priority levels set in advance, the recall timing corresponding to this priority level is extracted, the current date and time is acquired from the time acquisition unit 170, The current date and time, recall timing, and priority are passed to the information search means 120 as search conditions.
The information search unit 120 refers to the information storage DB 140, acquires the same priority, the difference between the current date and time and the previous recall date is greater than the recall timing, and sets the previous recall date to the current date and time. The information storage DB 140 is updated by replacement, and the search result is temporarily stored in the storage device.
After performing the above search for all priorities in the priority list, the search results temporarily stored in the storage device are passed to the recalling means 150.

(3) Timing by Schedule Data The current date is acquired from the time acquisition unit 170, and the schedule data related to this date is acquired via the schedule data acquisition unit 165.
The information on “location”, “action”, and “partner” included in the schedule data is passed to the information search means 120 as a search condition, and the information search means 120 searches the information storage DB 140 for “situation to remember” using this search condition. The search result is passed to the recalling means 150.

The recall unit 150 converts the information obtained at the above three timings into a format suitable for notification by referring to the type of information, passes the converted notification information to the notification unit 230, and notifies the notification unit In 230, according to the format of the notification information, the user is notified that there is information by any one or combination of the following.
• Sound an alarm or beep.
-Display / reproduce the title and contents of information on the display device.
・ Play information content from speakers.

  For example, FIG. 18 shows an example of a reminder screen notified at the timing based on priority. In the figure, the title of the information that came up is “plan”, and the contents of this plan are recorded by voice. By executing the play icon, the contents of the plan can be heard. In addition, this plan suggests that it must be implemented as “Mr. Planning Department A” and “New Plan Meeting”.

By configuring the fourth embodiment as described above, it is possible to input what has been thought of using an existing familiar device, such as voice blowing by an IC recorder or simple video shooting, without requiring a special device. , You can easily input the information you have come up with, reducing the input burden.
In addition, it is possible to reduce the burden of inputting date and time information by linking with a separately managed schedule management system.
