Description

  The present invention relates to a display control device, a control method for a display control device, and a program.

  When an emergency situation (target event) such as a natural disaster occurs, a report on the target event (for example, the status of damage, the response status of the case that occurred according to the target event, etc.) From the corresponding department to the response headquarters that supervises the response to the target event.

  In such a report, in the case of a standardized report, a form in which the form and the like are arranged in advance is often prepared. In this case, the reporter only has to input damage or response status along the form, and the burden of reporting is reduced. Moreover, the countermeasures headquarters also facilitates automatic tabulation and aggregation of reports, and it is easy to grasp the situation from a bird's-eye view by tabulating reports and displaying them on a map.

  However, in the case of reports that have not been standardized, it is common for reports to be made by free description by the reporter. In particular, in the event of an emergency such as a natural disaster, many such reports are not made. In this case, it is difficult to grasp the situation from a large amount of free description sentences (text sentences) and to examine a response policy.

  As a technique for grasping the status of a target event, there is a technique using a thread display that is used for displaying an e-mail or a bulletin board (BBS: Bulletin Board System). In this technique, responses to a specific topic (thread) are classified as a group. Therefore, since a report on a specific topic can be grasped as a series of flows, it becomes easy to grasp the situation on the specific topic.

  In addition, as a technique for examining a response policy for a target event, Patent Document 1 discloses a technique for accumulating know-how for past events and providing know-how for responding to past events similar to the target event. It is disclosed.

  However, in the technology using thread display, the reporter confirms whether there is a thread corresponding to the report content, and if a thread similar to the report content exists, that thread corresponds to the report content. It is necessary to check whether or not. As a result, the efficiency of the reporting process decreases. Further, with this technology, it is possible to grasp the situation regarding a specific topic, but it is difficult to grasp the situation of the entire target event from a bird's-eye view.

  Moreover, in the technique disclosed in Patent Document 1, it is difficult to perform an appropriate response even if the know-how for the past event is referred to unless the situation of the entire target event is grasped.

  An object of the present invention is to provide a display control apparatus, a display control apparatus control method, and a program capable of solving the above-described problems and more efficiently performing a report on the target event and an overview of the status of the target event. There is to do.

  Embodiments of the present invention will be described below.

  FIG. 1 is a block diagram showing a configuration of a crisis response information display control device 100 according to an embodiment of the present invention. As shown in FIG. 1, the crisis response information display control device 100 is connected to a client terminal 11 provided in a disaster countermeasure headquarters or the like via a network 10 and controls display on the display unit of the client terminal 11. Device.

  A crisis response information display control device 100 shown in FIG. 1 includes a storage unit 110 and a control unit 120. The storage unit 110 includes an activity log storage unit 111, a list storage unit 112, and a classification result storage unit 113. The control unit 120 includes a case management unit 121, an overhead view display search unit 122 (display control unit), and a dynamic axis setting unit 123.

  The activity log accumulation unit 111 accumulates an activity log that is a report related to a non-standardized matter that occurs in response to the target event.

  FIG. 2 is a diagram illustrating a configuration example of an activity log accumulated by the activity log accumulation unit 111.

  As shown in FIG. 2, in the activity log, the event ID for identifying the case, the registration date / time of the case, the occurrence date / time of the case, the response status tag (not supported / supported / completed), and the priority tag (high) / Medium / Low), Importance tag (High / Low), Response start date / time when response started, Response end date / time when response ended, Item request source, Item request destination, Item name And the contents of the case and the answer to the case are associated with each other. The activity log storage unit 111 can also sort the activity logs in chronological order based on the registration date and time and occurrence date and time. In addition, the subject name and contents of the project are usually input by free description by the reporter. The response start date and time and the response end date and time are sequentially input in accordance with changes in the response status.

  Referring back to FIG. 1, the list storage unit 112 stores an axis setting list in which classification axes set according to the related items of the target event are registered. The related items of the target event include, for example, matters that need to be handled depending on the target event and the situation of the target event for each region. The classification axis is set in advance based on the region or department unit, the type of response business based on the crisis response manual, ESF (Emergency Support Function) indicating the function of the disaster response business, and the like. In addition, as will be described later, the list storage unit 112 divides the classification axis registered in the axis setting list, and when a new classification axis is set, the new classification axis is registered. Accumulate axis management list. Further, the list storage unit 112 stores a list management table for managing an axis setting list in which each classification axis is registered when the classification axes are set based on different criteria.

  FIG. 3 is a diagram illustrating a configuration example of an axis setting list accumulated by the list accumulation unit 112. FIG. 3 shows an example in which the classification axis is set based on the ESF.

  As shown in FIG. 3, in the axis setting list, the name of the classification axis, the contents of the classification axis, and a new axis link that indicates a link to the newly set classification axis when the classification axis is divided. It is associated. If the classification axis is not classified, “(empty)” is registered in the new axis link. It should be noted that the contents of the classification axis are desirably described in detail because they serve as indices for natural language processing by the overhead view display search unit 122 and the dynamic axis setting unit 123 described later.

  When the classification axis is divided, as shown in FIG. 4, the classification axis “ESF # 1 transportation support” is divided into a new axis list corresponding to the divided classification axis “ESF # 1 transportation support”. A link “ESF # 1_001” to a new axis management list for managing a newly set classification axis is registered.

  FIG. 5 is a diagram illustrating a configuration example of a new axis management list stored in the list storage unit 112.

  As shown in FIG. 5, in the new axis management list, a newly set classification axis name (new axis name) is associated with a new axis link. Therefore, the newly set classification axis can be divided and further subdivided.

  FIG. 6 is a diagram illustrating a configuration example of an axis setting list accumulated by the list accumulation unit 112.

  As shown in FIG. 6, in the axis setting list, an axis setting list ID (list ID) and a list name are associated with each other. In the example of FIG. 6, list 1 is an axis setting list based on ESF, and list 2 is an axis setting list based on area names.

  Referring again to FIG. 1, the classification result storage unit 113 stores the classification results obtained by classifying the input activity log according to the classification axis registered in the axis setting list stored in the list storage unit 112 as a classification result management table. To do.

  FIG. 7 is a diagram illustrating a configuration example of the classification result management table accumulated by the classification result accumulation unit 113.

  As shown in FIG. 7, in the classification result management table, an activity log ID (event ID) is associated with the name of the classification axis into which the activity log is classified. FIG. 7 shows an example in which a plurality of axis setting tables are provided. In the example of FIG. 7, the activity log with the event ID “001” is classified into the classification axis with the name “ESF # 1 transportation support” in the axis setting list based on the ESF with the list ID “list 1”. In the axis setting list based on the area name of “List 2”, it is classified into the classification axis of the name “A town”.

  Referring to FIG. 1 again, the case management unit 121 receives a report (activity log) to the disaster countermeasure headquarters, manages the input activity log as a case, and manages the input activity log as an activity log storage unit. It accumulates in 111. In addition, the case management unit 121 updates the activity log stored in the activity log storage unit 111 according to changes in the response status.

  The bird's-eye view display search unit 122 classifies the activity log according to the classification axis registered in the axis setting list stored in the list storage unit 112 and stores the classification result in the classification result storage unit 113. As described above, an activity log that has not been standardized is often reported as a free description by the reporter. The bird's-eye view display search unit 122 categorizes activity logs by analyzing free description sentences using natural language processing, which is a technology for processing natural language on a computer.

  The overhead view display search unit 122 displays an image corresponding to the classification result stored in the classification result storage unit 113 on the display unit of the client terminal 11.

  When the number of activity logs classified into a certain classification axis becomes larger than a predetermined threshold (for example, a value obtained by multiplying the average value of the number of activity logs classified into another classification axis) by the dynamic axis setting unit 123. Then, the classification axis is divided (subdivided) and a new axis is set.

  Next, a display example by the overhead view display search unit 122 will be described.

  FIG. 8 is a diagram illustrating a display example by the overhead view display search unit 122. FIG. 8 shows an example in which an axis setting list based on ESF (list 1) and an axis setting list based on area name (list 2) are provided.

  The overhead view display search unit 122 refers to the classification result management table, and as shown in FIG. 8, the classification axes based on ESF (ESF # 1, ESF # 2, ESF # 3, ESF # 4, ESF # 5,... -) And for each classification axis (A town, B town, C town,...) Based on the area name, an overview of the activity log classified on each classification axis is displayed (overhead display).

  As an example of display of the outline of the activity log, as shown in FIG. 8, an example of displaying a breakdown of the activity status correspondence tags (corresponding / not yet supported / completed) of the activity log classified on each classification axis as a pie chart 13 is shown. is there. Instead of the response status, the breakdown of priority tags and importance tags may be displayed in a pie chart. The display examples of the activity log summary are not limited to these examples, and the display format and display items are particularly limited as long as the activity log trend and response status for each classification axis can be ascertained. Not.

  FIG. 8 shows a display example using two axes, ie, a classification axis based on ESF and a classification axis based on region name, but is not limited thereto. A single axis (one axis setting list) may be used for display, or three axes (three or more axis setting lists) or more may be used for display.

  Further, the overhead view display search unit 122 displays a detail button 14 for displaying the details of the activity log for each classification axis. When the fact that the detail button 14 of a certain classification axis is pressed is input through the input device of the client terminal 11, for example, the overhead view display search unit 122 is classified into the classification axis as shown in FIG. Display a list of activity logs (detailed display).

  As shown in FIG. 8, the activity log is classified according to the classification axis set according to the related item of the target event, and the image according to the classification result is displayed (overhead view), so that the situation of the entire target event can be easily performed. Can be seen from a bird's-eye view. Therefore, it becomes easy to grasp the progress of the response to the target event and to allocate resources necessary for the response. Further, when the detail button 14 is pressed and display of the details of the activity log classified in each classification axis is requested, the details of the activity log classified in the classification axis are displayed as shown in FIG. Display) makes it easy to grasp detailed information such as the progress of each corresponding item.

  As described above, when the number of activity logs classified into a certain classification axis becomes greater than a predetermined threshold, the dynamic axis setting unit 123 divides the classification axis and sets a new axis. Below, the division | segmentation of the classification axis | shaft by the dynamic axis setting part 123 is demonstrated with reference to FIG. 10 and FIG.

  The dynamic axis setting unit 123 uses natural language processing to divide the feature space 15 represented by vectorizing (coordinated) each activity log classified as the division target classification axis by the feature amount, Divide the classification axis. Assuming that the number of divisions of the feature space 15 is N, the dynamic axis setting unit 123 determines that the value obtained by dividing the number of activity logs classified into the division target classification axes by N is the activity log classified into other classification axes. N is determined to be approximately equal to the number of.

  Then, the dynamic axis setting unit 123 equally divides the feature space 15 according to the division number N, for example, as indicated by a broken line in FIG. Alternatively, the dynamic axis setting unit 123 considers the density distribution of the feature space 15 as shown by a broken line in FIG. 11, that is, the density of each feature space (class) after division is approximately the same. The feature space 15 is divided.

  After dividing the feature space 15, the dynamic axis setting unit 123 assigns keywords (for example, words having a high appearance frequency) related to the activity log included in the feature space (class) after the division to the classification axis corresponding to the class. Set as the name of.

  When the classification axis is divided, the overhead view display search unit 122 expands and displays the subdivided classification axis in the overhead view display, and collapses the subdivided classification axis as necessary to return to the original classification axis. (Classification axis before being subdivided) may be displayed.

  FIG. 12 is a flowchart showing the operation of the crisis response information display control device 100.

  For example, when an activity log is input via the client terminal 11, the case management unit 121 registers the activity log as a new case in the activity log storage unit 111 (step S101). Then, when the fact that the correspondence of the matter has been started is input, the matter management unit 121 updates the correspondence status tag of the activity log to “being supported” (step S102). In addition, when it is input that the handling of the case has been completed, the case management unit 121 updates the correspondence status tag of the activity log to “completed” (step S103), and ends the management of the case. Note that the case management unit 121 also updates the response start date and time and the response end date and time of the activity log according to changes in the response status.

  The overhead view display search unit 122 classifies the input activity log according to the classification axis registered in the axis setting list based on the content of the activity log (step S104). Then, the overhead view display search unit 122 stores the classification result in the classification result storage unit 113 (step S105).

  Next, the overhead view display search unit 122 refers to the classification result management table and performs, for example, an overhead view display as illustrated in FIG. 8 on the client terminal 11. Further, when the display of the details of the activity log classified on a certain classification axis on the overhead view display is requested, the overhead view display search unit 122 displays a detailed display showing a list of the activity logs classified on the classification axis on the client terminal. 11 (step S106).

  When the activity log is classified into a certain classification axis, the dynamic axis setting unit 123 determines that the number of activity logs classified into the classification axis is a predetermined threshold (for example, the number of activity logs classified into other classification axes). It is determined whether or not the average value is larger than a predetermined number of times (for example, a value obtained by multiplying by 5) (step S107).

  If it is determined that the number of activity logs for the classification axis is not greater than the predetermined threshold (step S107: No), the dynamic axis setting unit 123 ends the process.

  When it is determined that the number of activity logs on the classification axis is greater than a predetermined threshold (step S107: Yes), the dynamic axis setting unit 123 divides (subdivides) the classification axis on which the activity log is classified ( Step S108).

  Then, the dynamic axis setting unit 123 registers the newly set classification axis in the list storage unit 112. The dynamic axis setting unit 123 registers the newly set classification axis in the classification result storage unit 113 (step S109). In the classification result accumulation unit 113, the activity log that has not been divided into the classification axes before the division is classified again according to the newly set classification axis, and is registered in the classification result management table. Thereafter, display processing by the overhead view display search unit 122 is performed.

  As described above, according to the present embodiment, the crisis response information display control device 100 is a report on a target event, and an activity log including a free description by the reporter is set as a related item of the target event based on the content of the activity log. A bird's-eye view display search unit 122 that classifies according to the set classification axis and displays an image according to the classification result on the display unit of the client terminal 11 is provided.

  Activity logs including free text are automatically classified according to a preset classification axis, so reports are made efficiently without the reporter being particularly aware of the report format and the classification destination of the report. be able to. In addition, since the activity log is automatically classified according to the classification axis corresponding to the relevant item of the target event, it is no longer necessary to classify while checking the free text included in the activity log, and the classification result Since the image according to the is displayed, the situation of the target event can be grasped from a bird's eye view more efficiently.

  Moreover, according to this embodiment, the overhead view display search part 122 displays the outline of the activity log classified into the classification axis on the display part for each classification axis. Therefore, the outline of the situation can be grasped for each classification axis, and the situation of the target event can be grasped from a bird's eye view more efficiently.

  In addition, according to the present embodiment, the overhead view display search unit 122 displays the details of the activity log classified on the classification axis when the summary of the activity log classified on the classification axis is displayed on the display unit. When requested, the details of the activity log classified on the classification axis are displayed on the display unit. Therefore, even when it is desired to grasp the details of an item corresponding to a specific classification axis, the details of the item can be easily displayed.

  Also, according to the present embodiment, the crisis response information display control device 100 divides the classification axis and sets a new classification axis when the number of activity logs classified into the classification axis exceeds a predetermined threshold. A dynamic axis setting unit 123 is provided. Therefore, it can be prevented that the number of activity logs classified into one classification axis becomes too large and it becomes difficult to grasp the situation regarding the classification axis.

  Further, according to the present embodiment, the dynamic axis setting unit 123 sets the name of the newly set classification axis based on the contents of the activity log classified into the newly set classification axis. Therefore, it is possible to intuitively grasp the contents of the activity log classified into the newly set classification axis.

  The method performed in the crisis response information display control device 100 according to the present invention may be applied to a program for causing a computer to execute. In addition, the program can be stored in a storage medium and can be provided to the outside via a network.
