Description

[Technical field]

[0001] The present invention relates to an information acquisition support device, an information acquisition support method, and an information acquisition support program. [Background technology]

[0002] When disasters, accidents, incidents, and other events occur, command centers such as fire departments or police stations that direct responses to these events receive reports about the event, understand the situation at the site of the event based on the information provided by the reports, and respond to the event. In some cases, the number of reports received by command centers can be large, and sorting through the information provided by these reports can take time, which can cause delays in responding to events. Therefore, there is a need for technology that can help sort through the information provided by these reports.

[0003] As a technology related to this technology, Patent Document 1 discloses a system in which, when a reporter makes multiple reports, a control center receives the reports and identifies duplicate reports by determining whether the reports are identical. Regarding this identity determination, this system determines whether a newly received report is caused by the same incident as a previously received report based on the correlation between the reporter's location, the time of the report, and the type of report. The control center in this system identifies a responder who will handle the incident based on the result of the identity determination, and notifies the identified responder of the response.

[0004] [Patent Document 1] JP 2019-179313 A Summary of the Invention [Problem to be solved by the invention]

[0005] When a command center receives a large number of reports (there may be cases where a large number of reports are generated regarding one event, or cases where a plurality of events are occurring), it is possible to organize the large amount of information to some extent by using, for example, the technology shown in the above-mentioned Patent Document 1. However, the technology shown in Patent Document 1 cannot be said to be sufficient in terms of supporting rapid and accurate understanding of the situation at the site where the event is occurring.

[0006] That is, the system according to Patent Document 1 judges whether multiple reports are about the same event, but does not organize the contents of those reports. For example, even if the reports are about the same event, the contents of the situation at the scene where the event occurred indicated by the multiple reports may not match or may be contradictory due to differences in the time and place where the reporter witnessed the event, or the reporter's perception of the event. In such cases, the command center cannot quickly and accurately grasp the situation at the scene where the event is occurring, which causes delays in appropriate response to the event. In other words, the challenge is to support a quick and accurate understanding of the situation at the scene where the event is occurring.

[0007] A primary object of the present invention is to provide an information acquisition support device and the like that supports rapid and accurate understanding of the situation at the site where an event is occurring. [Means for solving the problem]

[0008] An information acquisition support device according to one embodiment of the present invention includes an acquisition means for acquiring a plurality of first reports related to a first event, an analysis means for analyzing the plurality of first reports based on an analysis criterion, and an event situation generation means for generating event situation information that integrates information indicated by the plurality of first reports based on an analysis result of the plurality of first reports and an information integration criterion.

[0009] In another aspect of achieving the above-mentioned object, an information acquisition support method according to one embodiment of the present invention includes an information processing device that acquires a plurality of first reports related to a first event, analyzes the plurality of first reports based on an analysis criterion, and generates event status information that integrates information indicated by the plurality of first reports based on an analysis result of the plurality of first reports and an information integration criterion.

[0010] In addition, in a further aspect of achieving the above-mentioned object, an information acquisition support program according to one embodiment of the present invention causes a computer to execute an acquisition process for acquiring multiple first reports related to a first event, an analysis process for analyzing the multiple first reports based on an analysis criterion, and an event situation generation process for generating event situation information that integrates information indicated by the multiple first reports based on an analysis result for the multiple first reports and an information integration criterion.

[0011] Furthermore, the present invention can also be realized by a computer-readable, non-volatile recording medium in which such an information acquisition assistance program (computer program) is stored. Effect of the Invention

[0012] According to the present invention, it is possible to obtain an information acquisition support device or the like that supports rapid and accurate understanding of the situation at the site where an event is occurring. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0015] <First embodiment> 1 is a block diagram showing a configuration of an information acquisition support device 10 according to a first embodiment of the present invention. The information acquisition support device 10 is a device that receives a large number of reports on events such as disasters (including natural disasters and man-made disasters), accidents, and incidents, integrates (aggregates) the information represented by the reports, and presents the integrated information to a command center such as a fire station or police station that directs a response to the events, or to relevant people in a local government, or to the general public.

[0016] The information acquisition support device 10 is communicatively connected to one or more smartphones 21, one or more surveillance cameras 22, one or more reporting devices 23, and one or more output devices 30 via a communication network 20. The communication network 20 is, for example, the Internet or a communication network that constitutes a telephone line.

[0017] The information acquisition support device 10 includes an acquisition unit 11, an analysis unit 12, an event situation generation unit 13, an integrated criterion generation unit 14, and a storage unit 15. The acquisition unit 11, the analysis unit 12, the event situation generation unit 13, and the integrated criterion generation unit 14 are examples of an acquisition means, an analysis means, an event situation generation means, and an integrated criterion generation means, respectively.

[0018] The storage unit 15 is, for example, a storage device such as a RAM (Random Access Memory) or a hard disk 904, which will be described later with reference to Fig. 5. The storage unit 15 stores report information 151, analysis criteria 152, analysis results 153, information integration criteria 154, event status information 155, and teacher data 156. The information stored in the storage unit 15 will be described in detail later.

[0019] The acquisition unit 11 acquires a plurality of reports (first reports) regarding an event that has occurred via the communication network 20. The acquisition unit 11 acquires information regarding the event transmitted by, for example, a person who witnessed the occurrence of the event via a smartphone 21. The transmitted information includes, for example, information (captured images, text documents, etc.) uploaded to a social networking service (SNS), an email sent to a command center, a call to 110 or 119 regarding the event, or a report via the Net119 emergency report system. Note that the Net119 emergency report system is a system provided in Japan by the Fire and Disaster Management Agency.

[0020] The acquisition unit 11 acquires, for example, an image of an event captured by a surveillance camera 22 installed in the vicinity of a place where the event occurred. The acquisition unit 11 may acquire images captured by the surveillance camera 22 at any time regardless of whether an event has occurred or not.

[0021] The acquisition unit 11 acquires, for example, a report made by a person who witnessed the occurrence of an event using the report device 23. The report device 23 is, for example, an emergency report device installed in a fire station or a branch station thereof.

[0022] The source of the report acquired by the acquisition unit 11 is not limited to the above-mentioned smartphone 21, the surveillance camera 22, and the reporting device 23. The acquisition unit 11 may acquire a report on an event that has occurred from a device other than the smartphone 21, the surveillance camera 22, and the reporting device 23.

[0023] The acquisition unit 11 stores the report information 151 representing the reports acquired as described above in the storage unit 15. The report information 151 includes at least one of the time when each report was made and the place where each report was made.

[0024] The analysis unit 12 analyzes the report information 151 stored in the storage unit 15 by the acquisition unit 11 based on the analysis criteria 152. The analysis criteria 152 are assumed to be given in advance to the information acquisition support device 10 by, for example, a user. For example, when the report represented by the report information 151 includes the voice of the reporter, the analysis unit 12 converts the voice of the reporter into a text document using an existing voice recognition technology based on the criteria used for voice recognition indicated by the analysis criteria 152. The analysis unit 12 performs syntactic analysis on the generated text document using an existing syntactic analysis technology based on the criteria used for syntactic analysis indicated by the analysis criteria 152. For example, when the report represented by the report information 151 is information represented by a text document such as an e-mail, the analysis unit 12 performs syntactic analysis on the text document.

[0025] By performing the above-mentioned syntax analysis, the analysis unit 12 extracts, for example, a phrase indicating the time or place contained in the report represented by the report information 151, and identifies the time or place of occurrence of the event. Note that, when the report information 151 is, for example, information uploaded to an SNS or an e-mail, the analysis unit 12 may extract information indicating the sending time or sending place of the report contained in such information. In this case, however, the analysis criteria 152 include criteria required for extracting information indicating the sending time or sending place of the report from the information uploaded to an SNS or an e-mail.

[0026] The analysis unit 12 also performs the above-mentioned syntax analysis to extract, for example, phrases (keywords) indicating the occurrence status of the event included in the report represented by the report information 151, and analyzes the occurrence status of the event. The analysis unit 12 analyzes the number of victims of the event by extracting, for example, phrases indicating the number of people, such as "3 people" or "5 people", from the report. The analysis unit 12 analyzes the scale of the occurrence of the event by extracting, for example, phrases indicating the scale of a fire, traffic accident, or the like, such as "2 houses" or "4 cars", from the report.

[0027] For example, when a report represented by report information 151 includes an image captured by smartphone 21 or surveillance camera 22, analysis unit 12 analyzes the captured image using existing image recognition technology based on the criteria used for image recognition indicated by analysis criteria 152. Analysis unit 12 determines that the event reported is a fire by, for example, detecting flames or smoke emanating from a house from the captured image and analyzes the occurrence of the fire. Alternatively, analysis unit 12 determines that the event reported is a traffic accident by, for example, detecting multiple vehicles damaged by a collision from the captured image and analyzes the occurrence of the traffic accident.

[0028] The analysis unit 12 stores in the memory unit 15 the analysis result 153 representing the situation of the event obtained by analyzing the situation of the event represented by the data such as text, audio, and images contained in the report information 151 based on the analysis criteria 152 as described above.

[0029] The event status generating unit 13 generates event status information 155 by integrating (aggregating) information indicated by a plurality of reports based on the analysis result 153 generated by the analyzing unit 12 as described above and the information integration criterion 154. Note that the information integration criterion 154 is a criterion indicating, for example, deleting duplication in the report information 151 and performing a predetermined statistical process on quantifiable information. The information integration criterion 154 may be given to the information acquisition support device 10 in advance by, for example, a user, or may be generated or updated by the integration criterion generating unit 14 described later.

[0030] For example, with regard to multiple reports represented by the report information 151, the event status generating unit 13 associates multiple reports with the same or similar sending time and sending place with the same event, and integrates the information indicated by the multiple reports associated with the same event. However, in this embodiment, "integrating" refers to, for example, deleting parts of information with overlapping content, and performing a predetermined statistical process (e.g., finding an average value, a median value, etc.) on quantifiable information. In this embodiment, "integrating" may be written as "aggregating" or "organizing".

[0031] When multiple reports associated with the same event indicate, for example, fires in three adjacent houses, the event status generation unit 13 integrates the overlapping information indicating fires in the three houses into a single event status information 155.

[0032] In the case where multiple reports associated with the same event contain multiple values, for example, regarding the number of houses where a fire has occurred, the event situation generating unit 13 performs a predetermined statistical process on the multiple values ​​and integrates the number of houses where a fire has occurred into the value resulting from the statistical process. For example, in the case where multiple reports associated with the same fire indicate that three to five houses are on fire, the event situation generating unit 13 integrates the number of houses where a fire has occurred into, for example, the maximum value of five houses. In this case, the information integration standard 154 indicates that, in the case where multiple reports contain multiple values ​​regarding the scale of the event, the scale of the event is integrated into the maximum value of the multiple values. This is based on the policy of recognizing the occurrence situation of the event as bad as possible so that a steady response to the event can be made.

[0033] The information integration standard 154 is not limited to the standard based on the above-mentioned policy. For example, when multiple reports include multiple numerical values ​​related to the scale of the occurrence of an event, the information integration standard 154 may indicate that the numerical values ​​are integrated into an average value. Alternatively, for example, when a numerical value that is significantly different from other numerical values ​​exists among the multiple numerical values ​​related to the scale of the occurrence of an event, the information integration standard 154 may indicate that the significantly different numerical value is ignored.

[0034] The event situation generating unit 13 stores the event situation information 155 generated as described above based on the analysis result 153 and the information integration criterion 154 in the storage unit 15. Then, the event situation generating unit 13 displays the generated event situation information 155 on the display screen of the output device 30.

[0035] Fig. 2 is a diagram illustrating an example of a manner in which the information acquisition support device 10 according to the present embodiment displays the generated event status information 155 on the display screen of the output device 30. In the example shown in Fig. 2, the event status generating unit 13 displays the damage status at the fire site, the activity status at the fire site, the captured image of the fire site, and the location of the fire site, which are represented by the event status information 155.

[0036] The damage situation at the fire scene illustrated in Fig. 2 represents information regarding the location (address) of the fire, the number of houses where the fire occurred, the shape of the houses where the fire occurred, the fire situation, and the rescue situation, which are integrated information represented by multiple reports by the event situation generating unit 13. The damage situation at the fire scene illustrated in Fig. 2 represents information regarding the fire stations that responded to the fire and the rescue situation, which are integrated information represented by reports from the fire stations.

[0037] The captured images of the fire scene illustrated in FIG. 2 are still images or moving images captured by the smartphone 21, the surveillance camera 22, or the like, and clearly show the situation of the fire scene. The event situation generating unit 13 selects and displays captured images that are consistent with the organized situation of the fire scene based on the analysis result of the captured images shown by the analysis result 153. The event situation generating unit 13 may display a plurality of captured images side by side on the display screen of the output device 30, for example. Alternatively, the event situation generating unit 13 may display real-time captured images transmitted from the smartphone 21, the surveillance camera 22, or the like on the display screen of the output device 30, for example.

[0038] 2 is information showing the location of the fire on a map. However, it is assumed that the information acquisition support device 10 is provided with map information of the area surrounding the fire.

[0039] The manner in which the event situation generating unit 13 displays the event situation information 155 on the display screen of the output device 30 is not limited to the manner exemplified in Fig. 2, and the event situation generating unit 13 may display the event situation information 155 on the display screen of the output device 30 in a manner different from that shown in Fig. 2. Furthermore, the event situation generating unit 13 may change the manner of the event situation information 155 according to the presentation destination of the event situation information 155, and display the event situation information 155 in a different manner for each presentation destination on the display screen of the output device 30 that presents the event situation information 155 to the presentation destination. However, the criteria for changing the manner of the event situation information 155 for each presentation destination is included in the information integration criteria 154.

[0040] For example, the activity status at the fire scene illustrated in Fig. 2 is information that the command center should grasp. Therefore, the event situation generating unit 13 may display the activity status at the fire scene on the display screen of the output device 30 for the command center, but may not display the activity status at the fire scene on the display screen of the output device 30 for the general public. Alternatively, for example, the event situation generating unit 13 may display even a highly stimulating captured image of the scene (where the devastation at the scene can be clearly understood) on the display screen of the output device 30 for the command center, but may not display a highly stimulating captured image of the scene on the display screen of the output device 30 for the general public.

[0041] 1 generates or updates an information integration standard 154 by performing machine learning such as deep learning by artificial intelligence such as a neural network on the relationship between the analysis result 153 and the event status information 155 using teacher data 156. Note that the teacher data 156 is information in which the analysis results of a plurality of reports (second reports) regarding an event (second event) that occurred in the past are associated with the actual occurrence status of the event. The teacher data 156 is assumed to be provided in advance to the information acquisition support device 10 by, for example, a user.

[0042] Next, the operation (processing) of the information acquisition support device 10 according to this embodiment will be described in detail with reference to the flowchart of FIG.

[0043] The acquisition unit 11 acquires reports on events from the smartphone 21, the surveillance camera 22, the reporting device 23, etc., and stores the reports as report information 151 in the storage unit 15 (step S101). The analysis unit 12 identifies the events represented by the reports from the time and place at which the reports were made, as represented by the report information 151 (step S102). The analysis unit 12 analyzes the report information 151 on each event based on the analysis criteria 152, and stores the analysis results 153 in the storage unit 15 (step S103).

[0044] The event situation generating unit 13 generates event situation information 155 that organizes the situation of the site where the event occurred for each event based on the analysis result 153 and the information integration standard 154 (step S104). The event situation generating unit 13 outputs the generated event situation information 155 via the output device 30 in a different mode according to the presentation destination of the event situation information 155 (step S105), and the entire process ends.

[0045] The information acquisition support device 10 according to this embodiment can support rapid and accurate understanding of the situation at the site where an event is occurring. This is because the information acquisition support device 10 analyzes multiple reports related to the event based on an analysis criterion 152, and generates event situation information 155 by integrating information indicated by the multiple reports based on the analysis result 153 and information integration criterion 154.

[0046] The effects achieved by the information acquisition support device 10 according to this embodiment will be described in detail below.

[0047] When a command center responding to an event such as a disaster or accident receives a large number of reports, for example, even if the reports are about the same event, the contents of the situation at the scene where the event occurred indicated by the multiple reports may not match or may be contradictory due to differences in the time and place where the reporter witnessed the event, or the reporter's perception of the event. In such cases, the command center cannot quickly and accurately grasp the situation at the scene where the event is occurring, which causes delays in appropriate response to the event. In other words, the challenge is to support a quick and accurate understanding of the situation at the scene where the event is occurring.

[0048] In response to such problems, the information acquisition support device 10 according to this embodiment includes an acquisition unit 11, an analysis unit 12, and an event situation generation unit 13, and operates as described above with reference to Figs. 1 to 3, for example. That is, the acquisition unit 11 acquires report information 151 representing a plurality of reports (first reports) related to an event (first event). The analysis unit 12 analyzes the report information 151 based on an analysis criterion 152. Then, the event situation generation unit 13 generates event situation information 155 that integrates information indicated by the plurality of reports based on an analysis result 153 for the report information 151 and an information integration criterion 154.

[0049] That is, the information acquisition support device 10 according to the present embodiment integrates (consolidates) the contents of multiple reports that contain overlapping or contradictory information regarding the situation at the site where the event occurred. This allows the information acquisition support device 10 to support quick and accurate understanding of the situation at the site where the event occurred.

[0050] Furthermore, the information acquisition support device 10 according to the present embodiment generates or updates the information integration standard 154 by performing machine learning on the relationship between the analysis results of a plurality of reports (second reports) regarding events (second events) that occurred in the past and the actual occurrence status of those events. This allows the information acquisition support device 10 to gradually increase the accuracy of the information integration standard 154, thereby increasing the accuracy of the event status information 155 to be generated.

[0051] Furthermore, the information acquisition support device 10 according to the present embodiment changes the mode of the generated event status information 155 depending on the presentation destination (command center, local government, general public, etc.) of the event status information 155, and outputs the event status information 155 in a different mode for each presentation destination via the output device 30. This allows the information acquisition support device 10 to avoid presenting, for example, information that is inappropriate or unnecessary for a certain presentation destination to the said presentation destination.

[0052] Furthermore, the information acquisition support device 10 according to this embodiment acquires reports via telephone calls, e-mails, information posts to SNS, images captured by a surveillance camera 22, and a report device 23 installed at a predetermined location via a smartphone 21. In this way, the information acquisition support device 10 integrates reports acquired via various routes, i.e., reports including a large amount of information regarding an event that has occurred, and therefore can generate more accurate event status information 155.

[0053] Furthermore, events that are the subject of reports acquired by the information acquisition support device 10 according to the present embodiment are not limited to the above-mentioned disasters (including natural disasters and man-made disasters), accidents, incidents, etc. For example, the information acquisition support device 10 may also be the subject of reports regarding items left behind in public transportation, or reports to hospitals when someone who has become ill is seen, etc. <Second embodiment> FIG. 4 is a block diagram showing a configuration of an information acquisition support device 40 according to the second embodiment of the present invention.

[0054] The information acquisition support device 40 according to this embodiment includes an acquisition unit 41, an analysis unit 42, and an event situation generation unit 43. The acquisition unit 41, the analysis unit 42, and the event situation generation unit 43 are examples of an acquisition means, an analysis means, and an event situation generation means, respectively.

[0055] The acquisition unit 41 acquires a plurality of reports 410 (first reports) related to an event (first event). The acquisition unit 41 may acquire the reports 410 from devices such as the smartphone 21, the surveillance camera 22, and the reporting device 23, similar to the acquisition unit 11 according to the first embodiment, for example. The plurality of reports 410 are information similar to the report information 151 according to the first embodiment, for example.

[0056] The analysis unit 42 analyzes a plurality of messages 410 based on analysis criteria 421. The analysis criteria 421 is, for example, a criterion similar to the analysis criteria 152 according to the first embodiment. The analysis unit 42 generates an analysis result 422 by operating, for example, in the same manner as the analysis unit 12 according to the first embodiment. The analysis result 422 is, for example, information similar to the analysis result 153 according to the first embodiment.

[0057] The event situation generating unit 43 generates event situation information 432 by integrating information indicated by the multiple reports 410 based on an analysis result 422 for the multiple reports 410 and an information integration criterion 431. The information integration criterion 431 is, for example, a criterion similar to the information integration criterion 154 according to the first embodiment. The event situation generating unit 43 generates the event situation information 432 by operating in the same manner as the event situation generating unit 13 according to the first embodiment. The event situation information 432 is, for example, information similar to the event situation information 155 according to the first embodiment.

[0058] The information acquisition support device 40 according to this embodiment can support the rapid and accurate understanding of the situation at the site where an event is occurring. This is because the information acquisition support device 40 analyzes multiple reports related to the event based on an analysis criterion 421, and generates event situation information 432 by integrating information indicated by multiple reports 410 based on the analysis result 422 and information integration criterion 431.

[0059] <Hardware configuration example> In each of the above-mentioned embodiments, each unit in the information acquisition support device shown in Fig. 1 and Fig. 4 can be realized by a dedicated HW (Hardware) (electronic circuit).

Acquisition units 11 and 41, Analytical units 12 and 42, Event situation generating units 13 and 43, ·Integrated standard generation unit 14 Memory control function in the memory unit 15.

[0060] However, the division of the various parts shown in these drawings is for the convenience of explanation, and various configurations may be assumed when implementing the system. An example of the hardware environment in this case will be described with reference to FIG.

[0061] Fig. 5 is a diagram for illustratively explaining the configuration of an information processing device 900 (computer) capable of realizing the information acquisition support device according to each embodiment of the present invention.

[0063] That is, the information processing device 900 including the above components is a general computer in which these components are connected via a bus 906. The information processing device 900 may include a plurality of CPUs 901, or may include a CPU 901 configured with a multi-core.

[0064] The above-described embodiment may supply a computer program capable of realizing the following functions to the information processing device 900 shown in FIG. 5. For example, the functions are the above-described configurations in the block diagrams (FIGS. 1 and 4) referred to in the description of the embodiment, or the functions of the flowchart (FIG. 3).

Examples of such procedures include a method of installing the program into the device via various recording media 907 such as a CD-ROM, or a method of downloading the program from an external source via a communication line such as the Internet. In such a case, the computer program supplied to the information processing device according to this embodiment can be considered to be composed of the code constituting the program, or the recording media 907 on which the code is stored.
