Description

Report management device, report management method, and recording medium

[0001] The present invention relates to a report management device, a report management method, and a recording medium.

[0002] When an accident, incident, disaster, or other event occurs, the fire department, police, etc. generally respond to the event after receiving a report. In these types of reports, multiple reports may be made for the same event. Therefore, if firefighters, police officers, etc. are dispatched for each report, they may be dispatched to the same event multiple times, which may result in delays in responding to other events or make it difficult to respond adequately. It is important to appropriately allocate resources, such as personnel and vehicles, to events.

[0003] For example, Patent Document 1 discloses an information assistance device that assists in quickly and accurately grasping the situation at the site where an event is occurring. This information acquisition assistance device includes an acquisition unit, an analysis unit, and an event situation generation unit. The acquisition unit acquires multiple reports related to the event. The analysis unit analyzes the multiple reports based on analysis criteria. The event situation generation unit generates event situation information that integrates information indicated by the multiple reports based on the analysis results of the multiple reports and information integration criteria.

[0004] For example, Patent Document 2 discloses a system for assisting in determining the condition of an injured or sick person. This system includes a determination unit that determines the condition of the injured or sick person from collected information about the injured or sick person, and an estimation unit that estimates questions corresponding to information to be collected from the collected information about the injured or sick person and determines the priority of the estimated questions.

[0006] While the technologies described in Patent Documents 1 and 2 can assist in grasping the situation at the scene of an incident and determining the condition of injured people, they do not provide a technology for determining whether the incidents related to the reports are the same. As a result, there is a risk that resources will be allocated to the same incident in an overlapping manner, making it difficult to respond to the incident appropriately and quickly.

[0007] In view of the above-mentioned problems, an example of an object of the present invention is to enable an appropriate and prompt response to an event.

[0008] According to one aspect of the present invention, a notification management device is provided, comprising: a similarity acquisition means for acquiring similarities between a plurality of pieces of notification information relating to an event using the plurality of pieces of notification information; and an identical event determination means for determining whether the events relating to each of the plurality of pieces of notification information are the same event using the similarities, wherein the similarities are acquired using environmental sounds included in each of the plurality of pieces of notification information.

[0009] According to one aspect of the present invention, a notification management method is provided in which one or more computers use a plurality of notification information related to an event to obtain a similarity between the plurality of notification information, and use the similarity to determine whether the event related to each of the plurality of notification information is the same event, and the similarity is obtained using environmental sounds included in each of the plurality of notification information.

[0010] According to one aspect of the present invention, a recording medium is provided having recorded thereon a program for causing one or more computers to perform the following operations: use a plurality of pieces of report information relating to an event to obtain a similarity between the plurality of pieces of report information; use the similarity to determine whether the event relating to each of the plurality of pieces of report information is the same event; and obtain the similarity using environmental sounds contained in each of the plurality of pieces of report information.

[0011] According to one aspect of the present invention, it is possible to respond to an event appropriately and quickly.

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, like components are designated by like reference numerals, and the description thereof will be omitted as appropriate.

[0014] 1 is a diagram showing an overview of a report management system 100 according to embodiment 1. The report management system 100 includes at least one base device 102 that generates report information related to an event based on a report received at a report reception base, and a report management device 103 that manages a plurality of reports.

[0015] FIG. 2 is a diagram showing an overview of the report management device 103 according to the first embodiment.

[0016] The report management device 103 includes a similarity acquisition unit 133 and an identical event determination unit 134. The similarity acquisition unit 133 uses a plurality of report information related to an event to acquire a similarity between the plurality of report information. The identical event determination unit 134 uses the similarity to determine whether the events related to each of the plurality of report information are the same event. The similarity is acquired using environmental sounds included in each of the plurality of report information.

[0017] The notification management system 100 makes it possible to respond to events appropriately and quickly. The notification management device 103 also makes it possible to respond to events appropriately and quickly.

[0018] FIG. 3 is a diagram illustrating an outline of the report management process according to the first embodiment.

[0019] The similarity obtaining unit 133 obtains similarities between the plurality of pieces of report information related to an event (step S106). The same-event determining unit 134 determines whether the events related to each of the plurality of pieces of report information are the same event using the similarities (step S107). The similarities are obtained using environmental sounds included in each of the plurality of pieces of report information.

[0020] This report management process makes it possible to respond to events appropriately and quickly.

[0021] A detailed example of the report management system 100 according to the first embodiment will be described below.

[0022] 4 is a diagram showing an example of the configuration of the report management system 100 according to the first embodiment. The report management system 100 is a system for managing a plurality of reports. The report management system 100 includes a reporter terminal 101, a base device 102, and a report management device 103, which are connected to each other via a network NT.

[0023] The network NT is a communication network configured by wired or wireless communication or a combination of these. The reporter terminal 101, the base device 102, and the report management device 103 transmit and receive information to and from each other via the network NT.

[0024] 1 and 4 show an example in which the report management system 100 includes one base device 102, but there may be a plurality of base devices 102. In addition, there may also be a plurality of reporter terminals 101.

[0025] (Regarding the reporter terminal 101 according to the first embodiment) The reporter terminal 101 is a terminal used by a reporter to report events such as accidents, incidents, and disasters. The reporter terminal 101 is a portable terminal equipped with, for example, a smartphone, a tablet terminal, etc. However, the reporter terminal 101 is not limited to this and may be a stationary terminal, etc.

[0026] 5 is a diagram showing an example of the functional configuration of the reporter terminal 101 according to embodiment 1. The reporter terminal 101 functionally includes, for example, a voice call unit 111 and a location information transmission unit 112.

[0027] The voice communication unit 111 performs processing for a voice call between a reporter who makes a report and a receiver who receives the report. The voice communication unit 111 establishes a call line with a report receiving center via a telephone line, network NT, etc. (not shown) in response to, for example, an operation by the reporter. This call line is a line through which the reporter makes a report using voice. This allows a call to be made between the reporter and the receiver.

[0028] The report reception center is a center that receives reports regarding events such as accidents, incidents, disasters, etc., and is appropriately set up in organizations that respond to events, such as fire departments, police, etc. The receiver is, for example, a person who receives reports at the report reception center.

[0029] When a call is made using the voice call unit 111, the location information transmission unit 112 acquires the current location of the reporter terminal 101 and transmits location information including the acquired current location to the device of the other party of the call. The location information transmission unit 112 may acquire the current location using, for example, at least one of a GPS (Global Positioning System) function, a wireless LAN (Local Area Network) function, etc.

[0030] When transmitting the location information, the location information transmitting unit 112 may request a predetermined operation to obtain the caller's consent for the transmission of the location information, using a screen display or the like on the caller terminal 101. Then, when the caller performs the predetermined operation, the location information transmitting unit 112 may transmit the location information to the device of the other party of the call.

[0031] (Regarding the base device 102 according to the first embodiment) The base device 102 is a device installed at a report receiving base. The base device 102 generates report information related to an event based on a report received at the report receiving base from the reporter terminal 101.

[0032] The notification information may be information about an event that can be generated based on a notification, and may include, for example, at least one of a notification sound, a notification time, and a notification location.

[0033] The notification sound is a sound included in the call sound for reporting, and includes a voice emitted by at least one of the caller and the call recipient, and an environmental sound other than the voices of the caller and the call recipient.

[0034] The notification time is the time when the notification was made. The notification time may include, for example, at least one of the start and end times of the notification and the call duration (e.g., length) for the notification. The start and end times may be expressed, for example, as a combination of date and time. Note that the information included in the notification time and the method of expressing the start and end times are not limited to those exemplified here.

[0035] The reporting location is the location where the report was made. The reporting location may be expressed using at least one of latitude and longitude, an address, and an area in a predetermined unit (e.g., near a certain intersection).

[0036] 6 is a diagram illustrating an example of the functional configuration of the base device 102 according to embodiment 1. The base device 102 functionally includes, for example, a message information generating unit 121 and a message information transmitting unit 122.

[0037] The report information generating unit 121 generates report information relating to an event based on a report received at a report receiving center.

[0038] For example, when a call line for a reporter to make a call is established in response to a request from the reporter terminal 101, the report information generation unit 121 acquires at least one of a call sound, a call time, a call location, etc. The report information generation unit 121 generates report information using the acquired at least one of the call sound, the call time, the call location, etc.

[0039] The notification sound may be acquired, for example, via a telephone line.

[0040] The notification time may be obtained using, for example, a timing function provided in the base device 102 .

[0041] The reporting location may be obtained, for example, using the location information transmitted by the location information transmission unit 112. That is, the reporting location in this case is a location (for example, the current location of the reporter terminal 101) obtained using the location information of the reporter terminal 101 used for the report.

[0042] The reporting location is not limited to the current location of the reporter terminal 101, but may be obtained using base station information used for the reporting. That is, the reporting location may be obtained using at least one of the base station information used for the reporting, the location information of the terminal used for the reporting, etc. The base station information used for the reporting is, for example, information regarding the location of a base station intervening in the communication line. The location of the base station may be indicated by the location of the base station (latitude and longitude, address, etc.) or by the area in which the base station establishes a communication line.

[0043] The report information transmitting unit 122 transmits the report information generated by the report information generating unit 121 to, for example, the report management device 103 .

[0044] (Regarding the notification management device 103 according to embodiment 1) In order to manage multiple notifications, the notification management device 103 uses multiple notification information to determine whether the events related to each of the multiple notification information are the same event (identity of events related to the notification information).

[0045] The plurality of pieces of report information according to this embodiment are an example of a group of report information generated based on each of a plurality of reports received at one report receiving base.

[0046] 7 is a diagram illustrating an example of the functional configuration of the report management device 103 according to embodiment 1. Functionally, the report management device 103 includes, for example, an analysis result storage unit 131, a report information acquisition unit 132, a similarity acquisition unit 133, an identical event determination unit 134, a display unit 135, and a display control unit 136.

[0047] The analysis result storage unit 131 is a storage unit for storing analysis information.

[0048] The analysis information includes the report information and the analysis result of the report information. The analysis result includes the content of the sound (sound content) and the environmental sound information acquired using the report information. The sound content and the environmental sound information will be described in detail later.

[0049] The report information acquisition unit 132 acquires the report information transmitted by the report information transmission unit 122. The report information acquisition unit 132 generates analysis information including the acquired report information and stores the analysis information in the analysis result storage unit 131.

[0050] The similarity acquisition unit 133 uses the plurality of pieces of report information acquired by the report information acquisition unit 132 to acquire similarities related to the plurality of pieces of report information.

[0051] 8 is a diagram illustrating an example of the functional configuration of the similarity acquisition unit 133 according to embodiment 1. Functionally, the similarity acquisition unit 133 includes, for example, a voice recognition unit 133a, an environmental sound analysis unit 133b, and a similarity calculation unit 133c.

[0052] The voice recognition unit 133a recognizes the voice content included in each of the plurality of pieces of message information acquired by the message information acquisition unit 132, and generates a recognition result.

[0053] For example, the voice recognition unit 133a generates text information (voice text information) indicating the content of the voice as a result of recognizing the voice contained in each of the plurality of pieces of report information.

[0054] The voice content is the content of the voice included in the call sound for reporting, and includes, for example, at least one of the location where the event occurred, the time when the event occurred, and the content of the event.

[0055] The environmental sound analysis unit 133b analyzes the environmental sound included in each of the plurality of pieces of report information acquired by the report information acquisition unit 132, and generates the analysis result.

[0056] As described above, environmental sounds are sounds other than voice that are included in the call sounds for reporting. Environmental sounds include, for example, at least one of weather-related sounds, walking sounds, and sounds generated from objects or facilities. Weather-related sounds include, for example, at least one of the sounds of rain and thunder. Walking sounds are, for example, sounds generated when a caller walks on at least one of gravel roads, dirt, puddles, etc. Sounds generated from objects or facilities include, for example, at least one of time signals, train whistles, emergency vehicle sirens, the sound of fireworks, cheers and music at facilities, etc.

[0057] The environmental sound analysis unit 133b then generates environmental sound information as a result of analyzing the environmental sounds included in each of the multiple pieces of notification information. The environmental sound information is, for example, text information (environmental sound text information) that indicates the type of environmental sound as described above. Note that the environmental sound information is not limited to text and may be, for example, information that includes environmental sounds extracted from call sounds as a result of the analysis.

[0058] The voice recognition unit 133a and the environmental sound analysis unit 133b store analysis information including the results of their recognition and analysis in the analysis result storage unit 131. In detail, for example, the voice recognition unit 133a and the environmental sound analysis unit 133b store analysis information in the analysis result storage unit 131, in which the results of their recognition and analysis are associated with the report information that was the subject of their recognition and analysis.

[0059] The voice recognition unit 133a and the environmental sound analysis unit 133b may each use common techniques such as pattern matching and machine learning models to recognize the voice content from the notification information (call sound) and analyze the environmental sound.

[0060] For example, the voice recognition unit 133a may include a voice recognition model that recognizes the voice content when notification information is input and outputs the result as text information or the like. The voice recognition model is a machine learning model that has been trained to recognize the voice content from the call sound included in the notification information. During training, training may be performed using training call sounds and correct answer data related to the voice content included in the call sounds.

[0061] For example, the environmental sound analysis unit 133b may include an environmental recognition model that, when notification information is input, analyzes environmental sounds and outputs the results as text information or the like. The environmental recognition model is a machine learning model that has been trained to analyze environmental sounds from call sounds included in the notification information. During training, training may be performed using training call sounds and correct answer data related to the environmental sounds included in the call sounds.

[0062] The similarity calculation unit 133c calculates the similarity between a plurality of pieces of report information.

[0063] For example, the similarity calculation unit 133c refers to the analysis information and calculates the similarity between each of the plurality of pieces of report information by using the results of recognition and analysis associated with each of the plurality of pieces of report information. That is, the similarity is obtained by using the environmental sound included in each of the plurality of pieces of report information. In this embodiment, the similarity is obtained by further using the audio content included in each of the plurality of pieces of report information.

[0064] In detail, for example, when analysis information (analysis information including the results of recognition and analysis) is generated for the most recent reporting information, the similarity calculation unit 133c calculates the similarity between the most recent reporting information and reporting information that satisfies specified conditions.

[0065] The most recent report information means report information generated based on the most recent report.

[0066] The predetermined condition is, for example, that the notification time is within a predetermined time (for example, within 30 minutes) from the notification time of the most recent notification information. The notification time here is the start or end time of the notification, but is not limited to these.

[0067] When there is a plurality of pieces of report information that satisfy the predetermined condition, the similarity calculation unit 133c calculates the similarity between the most recent report information and each piece of report information that satisfies the predetermined condition. In this way, the plurality of pieces of report information (e.g., the most recent report information and at least one piece of report information that satisfies the predetermined condition) from which similarity is to be obtained have a predetermined relationship in the report times, which are the times when the multiple reports were made to generate each piece of report information. Note that the predetermined relationship is not limited to the relationship exemplified here.

[0068] The similarity of the report information is, for example, a value obtained by calculating the similarity for each corresponding item (item similarity) between the report information to be compared and integrating the item similarities. For the integration, for example, a value obtained by adding up the item similarities, an average value of the item similarities, a weighted average value of the item similarities, etc. may be used.

[0069] The item similarity may be calculated using a predetermined method depending on the magnitude of the difference (gap) between the report location, the report time, the event occurrence location, and the event occurrence time. Examples of the predetermined method include a formula, a table, etc. that defines the relationship between the difference and the similarity. Furthermore, for the content of the event and the environmental sound, the item similarity may be calculated based on the percentage of all texts or keywords that match the text or keywords that represent the content of the event and the environmental sound.

[0070] Referring again to Fig. 7, the same event determination unit 134 uses the similarity acquired by the similarity acquisition unit 133 to determine whether the events related to each of the plurality of pieces of report information are the same event.

[0071] The display unit 135 displays various types of information. The display control unit 136 causes the display unit 135 to display various types of information. For example, the display control unit 136 causes the display unit 135 to display a report management screen including at least one of the similarity degrees acquired (calculated) for multiple pieces of report information, the determination results of whether or not the events are the same, etc. A detailed example of the report management screen will be described later.

[0072] The report management system 100 may not include the base device 102, and the report management device 103 may have the functions of the base device 102.

[0073] (Example of physical configuration of the report management system 100 according to the first embodiment) The report management system 100 is physically composed of, for example, a reporter terminal 101, a base device 102, and a report management device 103, which are connected via a network NT. Each of the reporter terminal 101, the base device 102, and the report management device 103 may be physically composed of, for example, a single device having a similar configuration. Below, an example of the physical configuration of the report management device 103 will be described with reference to the drawings.

[0074] Note that one or more of the reporter terminal 101, the base device 102, and the report management device 103 may be physically configured as multiple devices. In this case, each device may also be physically configured in the same manner as the report management device 103 described below.

[0075] 9 is a diagram illustrating an example of the physical configuration of the report management device 103 according to embodiment 1. The report management device 103 physically includes, for example, a bus 1010, a processor 1020, a memory 1030, a storage device 1040, a network interface 1050, an input interface 1060, and an output interface 1070.

[0076] The bus 1010 is a data transmission path for transmitting and receiving data among the processor 1020, memory 1030, storage device 1040, network interface 1050, input interface 1060, and output interface 1070. However, the method of connecting the processor 1020 and the like to each other is not limited to bus connection.

[0077] The processor 1020 is implemented as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit).

[0078] The memory 1030 is a main storage device realized by a RAM (Random Access Memory) or the like.

[0079] The storage device 1040 is an auxiliary storage device realized by a hard disk drive (HDD), a solid state drive (SSD), a memory card, a read-only memory (ROM), or the like. The storage device 1040 stores program modules for realizing the functions of the device that includes the storage device 1040. The processor 1020 loads each of these program modules into the memory 1030 and executes them to realize the function corresponding to that program module.

[0080] The network interface 1050 is an interface for connecting a device equipped with it to the network NT.

[0081] The input interface 1060 is an interface for the user to input information, and is configured from, for example, a touch panel, a keyboard, a mouse, and the like.

[0082] The output interface 1070 is an interface for presenting information to the user, and is configured, for example, by a liquid crystal panel, an organic EL (Electro-Luminescence) panel, or the like.

[0083] (Example of Operation of the Report Management System 100 According to the First Embodiment) The report management system 100 executes a report management process for managing multiple reports. The report management process is started when a communication line is established between the reporter terminal 101 and the base device 102. This communication line is established, for example, when a reporter uses the reporter terminal 101 to call a predetermined telephone number such as 110, 119, 9110, or 7119, and the call is accepted by the receiver. Note that the trigger for starting the report management process and the method for establishing a communication line are not limited to those exemplified here.

[0084] FIG. 10 is a diagram illustrating an example of the flow of a report management process according to the first embodiment.

[0085] For example, while a call line with the reporter terminal 101 is established, the report information generation unit 121 generates report information including a call sound that is a sound transmitted and received via the communication line (step S101). At this time, the report information generation unit 121 may acquire the report time, the report location, etc., for example, before the call ends, and include the acquired report time, the report location, etc. in the report information.

[0086] The notification information generation unit 121 determines whether the call has ended (Step S102). If the notification information generation unit 121 determines that the call has not ended (Step S102; No), the notification information generation unit 121 continues Step S101.

[0087] When the caller or the call recipient performs a predetermined operation to end the call, the call information generating unit 121 disconnects the call line and determines that the call has ended (step S102; Yes).

[0088] The notification information transmitting unit 122 transmits the notification information generated in step S101 to the notification management device 103 (step S103).

[0089] The message information acquisition unit 132 acquires the message information transmitted in step S103 (step S104).

[0090] The message information acquisition unit 132 generates analysis information including the message information acquired in step S104, and stores the analysis information in the analysis result storage unit 131 (step S105).

[0091] The similarity obtaining unit 133 obtains the similarity between the report information obtained in step S104 (the most recent report information) and the report information that satisfies a predetermined condition (step S106).

[0092] FIG. 11 is a flowchart showing an example of the similarity obtaining process (step S106) according to the first embodiment.

[0093] The voice recognition unit 133a acquires the message information acquired in step S104 (the most recent message information) and message information that satisfies a predetermined condition (step S106a).

[0094] The voice recognition unit 133a recognizes the voice content included in each of the plurality of pieces of report information acquired in step S106a, and generates a recognition result (step S106b).

[0095] The environmental sound analysis unit 133b analyzes the environmental sound included in each of the plurality of pieces of report information acquired in step S106a, and generates the analysis result (step S106c).

[0096] The voice recognition unit 133a and the environmental sound analysis unit 133b store analysis information in the analysis result memory unit 131 that associates the recognition results and analysis results with the notification information that was the subject of each recognition and analysis (step S106d).

[0097] The similarity calculation unit 133c calculates the similarity between the plurality of pieces of report information acquired in step S106a (step S106e), and returns to the report management process.

[0098] For example, the similarity calculation unit 133c calculates the similarity between each of at least one piece of report information that satisfies a predetermined condition and the most recent piece of report information.

[0099] Referring again to Fig. 10, the same event determination unit 134 uses the similarity calculated in step S106e to determine whether the events related to the plurality of pieces of report information acquired in step S106a are the same event (step S107).

[0100] For example, the same event determination unit 134 determines whether the event relating to each of at least one piece of report information that satisfies a predetermined condition and the event relating to the most recent report information are the same event.

[0101] The display control unit 136 causes the display unit 135 to display the report management screen (step S108), and ends the report management process.

[0102] As described above, the report management screen includes at least one of the similarity calculated in step S106e, the determination result in step S107, and the like.

[0103] 12 is a diagram showing a first example of a notification management screen. The notification management screen shown in FIG. 12 is an example in which the similarity between the most recent notification information and each of multiple notification information that meets a predetermined condition is represented by a color intensity. In the same figure, an example is shown in which the darker the color, the higher the similarity, but the method of associating the similarity with the color is not limited to this.

[0104] Fig. 13 is a diagram showing a second example of the report management screen. The report management screen shown in Fig. 13 is an example that includes information related to the most recent report information based on a report received on "Line: 1" and report information based on a report received on "Line: 3" among the report information that satisfies predetermined conditions.

[0105] The information displayed on the report management screen illustrated in FIG. 13 includes the results of recognizing audio content, the distance between report locations, and the results of analyzing environmental sounds (ambient acoustic information). In the results of recognizing audio content, parts with high similarity are underlined. In the results of analyzing environmental sounds, information indicating environmental sounds contained in each piece of report information that has high similarity is marked with a predetermined mark (a rectangular frame in FIG. 13 ). That is, in FIG. 13 , for some or all of the corresponding items between specific pieces of report information, the display mode of parts with high similarity (e.g., equal to or greater than a predetermined value) is displayed more emphasized than the other parts. The report management screen illustrated in FIG. 13 is an example of a screen in which some or all of the corresponding items between specific pieces of report information are displayed in different display modes depending on the similarity. This type of report management screen is suitable for comparing events related to specific pieces of report information.

[0106] (Actions and Effects) As described above, according to this embodiment, the report management device 103 includes a similarity acquisition unit 133 and an identical event determination unit 134. The similarity acquisition unit 133 uses multiple pieces of report information related to an event to acquire similarities between the multiple pieces of report information. The identical event determination unit 134 uses the similarities to determine whether the events related to each piece of report information are the same event. The similarities are acquired using environmental sounds included in each piece of report information.

[0107] This allows the system to use environmental sounds to determine the identity of events related to the notification information, improving the accuracy of the determination. This reduces the need to allocate resources to the same events in an appropriate manner, thereby enabling the system to respond to events appropriately and quickly.

[0108] According to this embodiment, the similarity is obtained by further using the voice content included in each of the plurality of pieces of report information.

[0109] This allows the accuracy of the determination to be improved by further using the voice content to determine the identity of the event related to the report information. This reduces the need to appropriately allocate resources to the same event, thereby enabling appropriate and prompt response to the event.

[0110] According to this embodiment, the plurality of pieces of report information includes a group of report information generated based on each of a plurality of reports received at one report receiving base.

[0111] This reduces the need to allocate resources to multiple incidents when responding to an incident based on a report to a certain reporting center, thereby enabling an appropriate and prompt response to the incident.

[0112] In the first embodiment, an example has been described in which the plurality of pieces of report information that are the targets of obtaining similarity and determining whether the events are the same (determination of event identity) include a report information group generated based on each of the plurality of reports received at one report reception center. The plurality of pieces of report information may include at least one of a report information group generated based on each of the plurality of reports received at one report reception center and a report information group generated based on each of the plurality of reports received at multiple report reception centers.

[0113] In the second embodiment, an example will be described in which the multiple pieces of report information to be used for similarity acquisition and event identity determination include a group of report information generated based on each of the multiple reports received at multiple report reception centers. This makes it possible to determine whether the events related to each of the multiple reports received at the multiple report reception centers are the same event. This makes it possible to reduce the overlapping allocation of resources to the same event for the multiple reports received at the multiple report reception centers.

[0114] Generally, each of the plurality of report receiving bases is associated with one or more of a plurality of predetermined areas of responsibility, and the one or more areas of responsibility associated with each of the plurality of report receiving bases may be different from one another or may be the same.

[0115] 14 is a diagram showing the relationship between report reception bases and coverage areas according to embodiment 2. The diagram shows an example of three report reception bases (first to third report reception bases) and their respective predetermined coverage areas (coverage areas A to C). That is, the diagram shows an example in which one or more coverage areas associated with the first report reception base, the second report reception base, and the third report reception base are different from one another.

[0116] The coverage area is an area corresponding to the incident related to the report received at the report receiving center. That is, in many cases, the report receiving center receives reports related to incidents occurring within the coverage area of ​​the report receiving center. The coverage area may be determined according to, for example, an administrative division such as a prefecture or a city, town, or village, but is not limited to this.

[0117] However, for example, if an event occurs in an area near the boundary of a coverage area, such as the specific area shown in the figure, a report reception base may receive a report regarding an event that occurred within the coverage area of ​​another report reception base. The figure shows an example in which a report regarding event P that occurred within a specific area of ​​coverage area A is reported to a second report reception base from a report position outside coverage area A but near the location where event P occurred (within the specific area). The report position shown in the figure is a specific area within coverage area B. Note that the specific area may be determined in advance as appropriate and is not limited to being near the boundary of a coverage area.

[0118] In this way, when a report reception center (the second report reception center in the example of FIG. 14 ) receives a report about an event (event P in the example of FIG. 14 ) that occurred outside the area covered by the report reception center, there is a possibility that a report about the event has also been received by another report reception center (the first report reception center in the example of FIG. 14 ). It may be more difficult for report reception centers with different areas of responsibility to share information about event reports than it is for report reception centers with the same area of ​​responsibility. Therefore, it is important to facilitate the sharing of information about reports between report reception centers with different areas of responsibility and to promote cooperation between these report reception centers.

[0119] In this embodiment, an example of cooperation between first and second notification reception centers will be described. Specifically, when a notification is received at a first notification reception center, the identity of an event related to the notification and an event related to a notification that satisfies a predetermined condition among multiple notifications received at the first and second notification reception centers will be determined.

[0120] When cooperation between report reception centers is attempted, the number of the report reception centers is not limited to two, and may be three or more. In this case, a report that satisfies a predetermined condition may be selected from a plurality of reports received at three or more report reception centers.

[0121] In this embodiment, for the sake of brevity, the configuration different from that of the first embodiment will be mainly described, and descriptions that overlap with the first embodiment will be omitted as appropriate.

[0122] 15 is a diagram showing an example of the configuration of a report management system 200 according to embodiment 2. The report management system 200 includes a reporter terminal 101 similar to the reporter terminal 101, base devices 102a and 102b, and a report management device 203.

[0123] The base device 102a is an example of a base device installed at a first report receiving base. The base device 102b is an example of a base device installed at a second report receiving base. Each of the base devices 102a and 102b may be configured similarly to the base device 102 according to the first embodiment, both functionally and physically.

[0124] That is, the multiple report reception bases according to this embodiment include a first report reception base and a second report reception base. Furthermore, the multiple pieces of report information generated by the base devices 102a and 102b include first report information and second report information generated based on reports received at the first report reception base and the second report reception base, respectively. The first report information is report information generated and transmitted by the base device 102a. The second report information is report information generated and transmitted by the base device 102b.

[0125] 16 shows an example of the functional configuration of the report management device 203 according to the second embodiment. Functionally, the report management device 203 includes, for example, a report information acquisition unit 232 and a similarity acquisition unit 233, which replace the report information acquisition unit 132 and the similarity acquisition unit 133 according to the first embodiment. Except for these, the report management device 203 may be configured functionally in a similar manner to the report management device 103 according to the first embodiment. Physically, the report management device 203 may be configured in a similar manner to the report management device 103 according to the first embodiment.

[0126] Similar to the notification information acquisition unit 132 in embodiment 1, the notification information acquisition unit 232 acquires the notification information sent by the notification information sending unit 122, generates analysis information including the acquired notification information, and stores it in the analysis result memory unit 131.

[0127] The message information acquisition unit 232 according to this embodiment acquires the message information transmitted by the message information transmission unit 122 of each of the base devices 102a and 102b.

[0128] The similarity acquisition unit 233 acquires a similarity between the plurality of pieces of report information acquired by the report information acquisition unit 232, using the plurality of pieces of report information. As described above, the plurality of pieces of report information includes first report information and second report information. For example, when the first report information is specific report information, the similarity acquisition unit 233 acquires the similarity between the first report information and the second report information. The specific report information is report information about an event that occurred in a predetermined specific area. In the example of FIG. 14 , the report information about event P is specific report information.

[0129] 17 shows an example of the functional configuration of the similarity acquisition unit 233 according to embodiment 2. Functionally, the similarity acquisition unit 233 includes, for example, a similarity calculation unit 233c that replaces the similarity calculation unit 133c according to embodiment 1, and further includes a specific message determination unit 233d. Except for these, functionally, the similarity acquisition unit 233 may be configured generally similarly to, for example, the similarity acquisition unit 133 according to embodiment 1.

[0130] The specific notification determination unit 233d determines whether the first notification information is specific notification information. This determination, i.e., whether the first notification information is specific notification information, may be made based on whether the notification location, which is the location where the notification for generating the first notification information was made, is within the specific area. As described in the first embodiment, the notification location may be included in the notification information.

[0131] The similarity calculation unit 233c may calculate the similarity between multiple pieces of report information, similar to the similarity calculation unit 133c according to embodiment 1. For example, when the specific report determination unit 233d determines that the first report information is specific report information, the similarity calculation unit 233c according to this embodiment calculates the similarity between the first report information and the second report information. Here, there may be multiple pieces of second report information to be used for calculating the similarity.

[0132] (Example of Operation of the Report Management System 100 According to the First Embodiment) The report management system 200 executes a report management process for managing a plurality of reports. Fig. 18 is a diagram showing an example of the flow of the report management process according to the second embodiment.

[0133] The message information transmitted from the base device 102a in step S103 is the first message information. The message information acquisition unit 132 acquires the message information transmitted in step S103 as the first message information (step S104).

[0134] The message information acquisition unit 132 generates analysis information including the first message information acquired in step S104, and stores the analysis information in the analysis result storage unit 131 (step S205).

[0135] Following S105, which is the same as in the first embodiment, the similarity acquisition unit 133 acquires a similarity between the first notification information (the most recent first notification information) acquired in step S204 and notification information that satisfies a predetermined condition (step S206). In this embodiment, the notification information that satisfies the predetermined condition includes first notification information and second notification information that satisfy the predetermined condition. There may be one or more pieces of first notification information and second notification information.

[0136] FIG. 19 is a flowchart showing an example of the similarity obtaining process (step S206) according to the second embodiment.

[0137] The specific message determination unit 233d determines whether the first message information acquired in step S204 is specific message information (step S206f).

[0138] For example, if the notification location included in the first notification information is not included in the specific area, the specific notification determination unit 233d determines that the first notification information is not specific notification information. If it is determined that the first notification information is not specific notification information (step S206f; No), steps S106a to S106e similar to those in the first embodiment are executed, and the process returns to the notification management process.

[0139] For example, if the notification location included in the first notification information is included in the specific area, the specific notification determination unit 233d determines that the first notification information is specific notification information. If the first notification information is determined to be specific notification information (step S206f; Yes), the notification information acquisition unit 232 acquires second notification information that satisfies a predetermined condition (step S206g).

[0140] For example, the report information acquisition unit 232 requests the base device 102b for second report information that satisfies a predetermined condition. In response to this request, the report information transmission unit 122 of the base device 102 selects and transmits report information that satisfies the predetermined condition from the report information generated by the base device 102b. This predetermined condition may be the same as in embodiment 1, for example. The base device 102b may also store a history of the report information. The report information acquisition unit 232 acquires the transmitted report information as the second report information (step S206g).

[0141] The message information acquisition unit 232 generates analysis information including the second message information acquired in step S206g, and stores the analysis information in the analysis result storage unit 131 (step S206h).

[0142] Next, steps S106a to S106e are executed as in the first embodiment, and the process returns to the notification management process. As a result, if there is second notification information that satisfies a predetermined condition in relation to the most recent first notification information, it is possible to obtain the similarity between the second notification information and the most recent first notification information, and to determine whether the cases are identical.

[0143] The method of acquiring the second notification information to obtain the similarity or determine the identity of the cases may be changed as appropriate.

[0144] For example, the message information acquisition unit 232 may acquire all of the message information generated by the base device 102b in advance as second message information, generate analysis information, and store it in the analysis result storage unit 131. It is desirable for the message information acquisition unit 232 to acquire the message information generated by the base device 102b in real time. In this case, the similarity acquisition process (step S206) may not include steps S206g to S206h. Then, for example, in step S106a, the speech recognition unit 133a may acquire the most recent first message information and message information that satisfies a predetermined condition from the analysis result storage unit 131. The method of acquiring second message information to acquire similarity or determine the identity of the cases is not limited to the example given here.

[0145] (Actions and Effects) As described above, according to this embodiment, the multiple pieces of report information include at least one group of report information generated based on each of the multiple reports received at multiple report reception centers.

[0146] This reduces the need to allocate resources to the same event in a timely manner when responding to an event based on reports received at multiple report receiving centers, thereby enabling an appropriate and prompt response to the event.

[0147] According to this embodiment, the multiple report reception locations include a first report reception location and a second report reception location. The multiple report information includes first report information and second report information generated based on reports received at the first report reception location and the second report reception location, respectively. When the first report information is specific report information related to an event that occurred in a predetermined specific area, the similarity acquisition unit 233 acquires a similarity between the first report information and the second report information.

[0148] This makes it possible to reduce the overlapping allocation of resources to the same event when responding to a report about an event that is likely to have occurred in a specific area based on the report received at the first report receiving center and the second report receiving center, thereby enabling an appropriate and prompt response to the event.

[0149] According to this embodiment, the report management device 203 acquires first report information and second report information. The similarity acquisition unit 233 includes a specific report determination unit 233d and a similarity calculation unit 233c. The specific report determination unit 233d determines whether the first report information is specific report information. When it is determined that the first report information is specific report information, the similarity calculation unit 233c calculates the similarity between the first report information and the second report information.

[0150] This makes it possible to reduce the overlapping allocation of resources to the same event when responding to a report about an event that is likely to have occurred in a specific area based on the report received at the first report receiving center and the second report receiving center, thereby enabling an appropriate and prompt response to the event.

[0151] According to this embodiment, whether the first notification information is specific notification information is determined based on whether the notification location, which is the location where the notification to generate the first notification information was made, is within a specific area.

[0152] This makes it possible to reduce the overlapping allocation of resources to the same event when responding to a report about an event that is likely to have occurred in a specific area based on the report received at the first report receiving center and the second report receiving center, thereby enabling an appropriate and prompt response to the event.

[0153] According to this embodiment, the reporting location is acquired using at least one of the base station information used for the reporting and the location information of the terminal used for the reporting.

[0154] This makes it possible to determine whether a report is related to an event that is likely to have occurred in a specific area. Therefore, when responding to a report related to an event that is likely to have occurred in a specific area based on reports received at the first report receiving center and the second report receiving center, it is possible to reduce the overlapping allocation of resources to the same event. Therefore, it is possible to respond to the event appropriately and quickly.

[0155] According to this embodiment, each of the plurality of report reception locations is associated with one or more of a plurality of predetermined areas of responsibility, and the one or more areas of responsibility associated with each of the first report reception location and the second report reception location are different from each other.

[0156] This allows for cooperation between call reception centers with different areas of responsibility, reducing the need to allocate resources to the same incident when it occurs in different areas of responsibility, and enabling appropriate and prompt response to the incident.

[0157] Although the embodiments of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than those described above can also be adopted.

[0158] In addition, although the flowcharts used in the above description show multiple steps (processes) in a sequential order, the order of steps executed in each embodiment is not limited to the order shown. In each embodiment, the order of the steps shown in the drawings can be changed as long as it does not cause any problems in terms of content.
