Information processing device and program

Abstract

To reduce a burden of answering a questionnaire as compared with the case where the present invention is not applied.SOLUTION: The present invention provides an information processing device that, upon acquiring an event information, transmits a questionnaire for confirming a degree of safety to a transmission destination corresponding to the event information, and receives an answer from the transmission destination. The information processing device has a first state (steady state mode) and a second state (emergency mode). In the second state (the emergency mode), the degree of safety obtained by receiving the answer from the transmission destination is held as safety information (S216), and when the safety information is held (Yes in S205), the safety information is updated according to the answer (S209) when the answer is received (S210). In the case of the second state (the emergency mode) (Yes in S203 or S204), when the event information is acquired (S201), the questionnaire to be transmitted to the transmission destination is created using the safety information held for the transmission destination (S207).SELECTED DRAWING: Figure 7

[Technical Field]

[0001] The present invention relates to an information processing device and a program. [Background technology]

[0002] There are various safety confirmation systems. For example, Patent Document 1 discloses an information management device capable of communicating with a plurality of terminals via a communication network, which includes: a transmission information generation unit that generates inquiry information for each inquiry, in which contact identification information of the person who is the subject of the inquiry is set, and stores the inquiry information in a storage unit in association with the contact identification information and a generation time; and a reception information reflection unit that converts received information, which is a response to the inquiry information, into a response to inquiry information whose generation time is earlier than the transmission time of the received information, which is stored in the storage unit in association with the contact identification information of the sender of the received information.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-65412 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, when a questionnaire is conducted to confirm the safety of individuals when an event occurs, the individuals whose safety is requested respond to the questionnaire about their current situation. When multiple events occur, a questionnaire is conducted for each event. When a questionnaire is conducted for each of multiple events, in order to ensure smooth operation of a system that uses questionnaires to confirm the safety of individuals, it is necessary to reduce the burden of responding to the questionnaire, for example. However, various configurations proposed in the past have not been sufficient in reducing the burden of responding to the questionnaire. The present invention aims to reduce the burden of responding to a questionnaire compared to when the present invention is not applied. [Means for solving the problem]

[0005] The information processing device of the present invention, which achieves the above-mentioned object, is an information processing device that, when it acquires event information, sends a questionnaire to confirm the safety of a destination corresponding to the event information and receives a response from the destination, and has a first state and a second state in which it stores the safety information obtained by receiving the response from the destination as safety information, and when it receives a response while storing the safety information, it updates the safety information to reflect the response, and when it acquires the event information in the second state, it creates the questionnaire to be sent to the destination using the safety information stored for the destination. More preferably, the safety information includes the safety and date and time information related to the questionnaire or the response, and when the safety information is updated, there are cases where the safety and the date and time information are updated, and cases where the safety is not updated but the date and time information is updated. Also, when there is no response to the questionnaire from the destination, the safety information is not updated. Furthermore, the safety information is retained until information indicating that an operation instructing a transition to the first state has been performed is received. Another program of the present invention that achieves the above-mentioned object has an information processing device that, when it acquires event information, sends a questionnaire to confirm the safety of a destination corresponding to the event information and receives a response from the destination, and has the following functions: a first state; and a second state in which the safety information obtained by receiving the response from the destination is stored as safety information, and when the safety information is stored and the response is received, the safety information is updated to reflect the response; and when the event information is acquired in the second state, the information processing device creates the questionnaire to be sent to the destination using the safety information stored for the destination. [Effects of the Invention]

[0006] According to the present invention, it is possible to reduce the burden of answering a questionnaire compared to when the present invention is not applied. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. <System configuration> FIG. 1 is a diagram showing an example of the configuration of a questionnaire system 10 according to this embodiment. When a survey implementation condition, which is a preset condition such as the occurrence of a disaster, is met, the survey system 10 implements a survey according to the survey implementation condition. That is, when a disaster, accident, etc. occurs, the survey system 10 prepares a survey regarding the damage situation for disaster victims or victims (hereinafter referred to as "specified persons") who may be facing the disaster or accident among predetermined persons (survey subjects) and sends the survey to the specified persons. When the survey system 10 receives the survey responses, it sends the survey responses to the company to which the specified persons belong.

[0009] Such a questionnaire system 10 comprises an information acquisition device 100, an administrator terminal device 200, a survey server 300, and a specified person terminal device 400. The information acquisition device 100 and the survey server 300, the administrator terminal device 200 and the survey server 300, and the specified person terminal device 400 and the survey server 300 are each connected via a network 500. The manager terminal device 200 referred to here is a terminal used by a manager who checks the safety of employees in an organization such as a company. The manager referred to here is, for example, a disaster prevention officer in the general affairs department. The specified person terminal device 400 is a terminal used by a specified person.

[0010] The network 500 may be any type of communication network used for data communication between devices, and may be, for example, a local area network (LAN), a wide area network (WAN), the Internet, etc. The communication lines used for data communication may be wired or wireless, or a combination of both. Furthermore, a gateway device, a router, or other relay device may be used to connect devices via multiple networks or communication lines.

[0011] 1, the information acquisition devices 100 are directly connected to the survey server 300 via the network 500, but a relay server such as an edge server may be used as an intermediary, and the relay server may collect information acquired by each information acquisition device 100 and send it to the survey server 300. In this case, location information related to the event to be detected may be stored in the relay server, and the relay server may send this information to the survey server 300 together with the information acquired by the information acquisition devices 100.

[0012] <Configuration of information acquisition device> The information acquisition device 100 is a device that acquires information necessary for the survey implementation server 300 to conduct a survey. That is, the information acquisition device 100 searches for information on other servers connected via the network 500 and acquires search result information. To explain the case where a natural disaster such as a meteorological disaster, earthquake, or eruption occurs, for example, when new meteorological disaster information or information related to lifelines is posted on the website of a public institution or private company, the information acquisition device 100 acquires the posted information such as earthquake information, tsunami information, weather information, and lifeline information. The posted information includes information indicating the type and extent of the disaster, as well as the location and time of the disaster.

[0013] The information acquisition device 100 may be connected to various devices such as sensors, cameras, microphones, etc., and may acquire information for determining whether a predetermined specific disaster-related event has occurred. The information acquisition device 100 may also acquire information that has suddenly increased through trend analysis on social media, for example, as information on incidents and accidents. The various types of information acquired by the information acquisition device 100 in this manner will be referred to as "event information" hereinafter.

[0014] <Configuration of administrator terminal device> FIG. 2 is a diagram showing the functional configuration of the administrator terminal device 200. As shown in FIG. As shown in FIG. 2, the administrator terminal device 200 includes a transmitting / receiving unit 201 , an implementation condition instructing unit 202 , a survey implementation information receiving unit 203 , a mode transition instructing unit 204 , and a display unit 205 .

[0015] The transmitting / receiving unit 201 is a network interface that connects to the information acquisition device 100, the survey implementation server 300, and the specified person terminal device 400 via the network 500 and exchanges data. The transmitting / receiving unit 201 transmits the conditions under which the survey will be conducted by the survey implementation server 300, and receives report data on the responses to the conducted survey.

[0016] The implementation condition instruction unit 202 has a function of allowing the user to specify implementation conditions for determining whether or not to conduct a survey when event information is acquired by the information acquisition device 100, and accepts input from the user. More specifically, the implementation conditions specified by the implementation condition instruction unit 202 are applied to subsequently acquired event information, and a determination is made as to whether or not to conduct a survey. As will be described later, the implementation conditions can include a plurality of elements, combining information indicating attributes such as area, degree, type, and time.

[0017] The survey information receiving unit 203 receives information about the survey conducted by the survey server 300 using the implementation conditions (hereinafter referred to as survey information). This survey information includes at least one of information indicating that a survey will be sent to a destination corresponding to the implementation conditions when the implementation conditions are met, information indicating the implementation conditions, and information indicating event information acquired via the information acquisition device 100.

[0018] As described above, the survey implementation information may include information indicating that, assuming that the administrator has acquired event information that satisfies the implementation conditions predetermined by the administrator, a survey will be sent to a destination corresponding to the implementation conditions, and may also include information indicating the implementation conditions and information indicating the event information when event information that satisfies the implementation conditions is acquired.

[0019] The mode transition instruction unit 204 has a function of instructing the survey server 300 to transition to normal mode when the survey server 300 is currently in emergency mode, and accepts input from the user. The following is a more detailed explanation. For example, when the survey server 300 receives event information indicating the occurrence of an earthquake, it transitions from normal mode to emergency mode and conducts a survey regarding the earthquake. In emergency mode, when it receives event information indicating the occurrence of a tsunami caused by the earthquake, it conducts a survey regarding the tsunami. On the other hand, if the administrator determines that the situation has been resolved as a result of subsequent developments, the mode transition instruction unit 204 issues an instruction to transition to the normal mode, in order to cancel the emergency mode and transition to the normal mode. In the emergency mode, the survey server 300 can manage the safety status, as will be described later.

[0020] The display unit 205 displays the report data sent as the results of the survey from the survey implementation server 300. This report data is the results of the survey based on the implementation conditions.

[0021] <Configuration of terminal device> Here, the administrator terminal device 200 and the specified person terminal device 400 (see FIG. 1) are realized by, for example, a personal computer (PC), a so-called tablet terminal device, a smartphone, or other information terminal device connectable to the network 500. Note that, although a single administrator terminal device 200 and a single specified person terminal device 400 are connected to the network 500, a plurality of each may be provided. Each of the terminal devices 200 and 400 displays various screens under the control of a display control unit (not shown), which is realized by, for example, a liquid crystal display, etc. Each of the terminal devices 200 and 400 also includes an operation device for user operation, such as a keyboard, a mouse, or a touch panel.

[0022] <Configuration of the survey server> The survey server 300 is a server that conducts surveys in response to event information acquired from the information acquisition device 100, and creates surveys by identifying the content and destination of the survey based on the acquired information. Furthermore, when the survey server 300 receives a survey response from a specific person, it forwards and reports the response to the company to which the specific person belongs.

[0023] Next, the functional configuration of the survey server 300 will be described. FIG. 3 is a diagram showing the functional configuration of the survey server 300. The survey server 300 comprises a transmission / reception unit 301 , a survey condition acquisition unit 302 , an attribute management unit 303 , a specified person extraction unit 304 , a survey data creation unit 305 , a safety status management unit 306 , and a report data creation unit 307 .

[0024] The transmitting / receiving unit 301 is a network interface that connects to the information acquiring device 100, the administrator terminal device 200, and the specified person terminal device 400 via the network 500 and exchanges data. The transmitting / receiving unit 301 receives information from the information acquiring device 100, transmits a questionnaire to the specified person terminal device 400 (see FIG. 1), and receives responses to the questionnaire. The transmitting / receiving unit 301 also transmits the responses to the questionnaire to the administrator terminal device 200.

[0025] The implementation condition acquisition unit 302 acquires and stores the implementation conditions transmitted from the administrator terminal device 200. As described above, the implementation conditions are conditions for determining whether or not to conduct a survey when event information is acquired, and are specified by the user.

[0026] The attribute management unit 303 manages and sets attributes for each piece of information acquired from the information acquisition device 100. That is, the attribute information, which is information on the set attributes, is a plurality of elements used when the user wants to narrow down information, and it is possible to narrow down the information by combining them.

[0027] In this embodiment, the attribute management unit 303 is provided in the survey server 300, but this is not limiting. That is, instead of the survey server 300 being provided with the attribute management unit 303, the information acquisition device 100 may be provided with it. Alternatively, the attribute management unit 303 may be provided in both the information acquisition device 100 and the survey server 300.

[0028] The specified person extraction unit 304 performs a specified person extraction process to extract specified people to complete a survey based on the event information acquired from the information acquisition device 100. This specified person extraction process, for example, analyzes the event information to determine areas that will be affected by an occurring disaster or the like, and identifies people who live or work in those areas, thereby extracting specified people who may be facing a disaster or accident.

[0029] The specific person extraction process by the specific person extraction unit 304 is performed using a database in which information on survey subjects is updated based on information acquired from the administrator terminal device 200 and the specific person terminal device 400 via the transmission / reception unit 301.

[0030] The specific person extraction process by the specific person extraction unit 304 is not limited to this. Another specific person extraction process involves analyzing event information to determine whether survey implementation conditions, which are conditions for determining whether a survey should be conducted, are met, and if the survey implementation conditions are met, extracting a specific person to conduct a survey. For example, when an earthquake occurs, the survey implementation conditions are that the magnitude or maximum seismic intensity is equal to or greater than a predetermined value, and if the survey implementation conditions are met, a specific person is extracted, but if the survey implementation conditions are not met, a specific person is not extracted.

[0031] Alternatively, a specific person may be extracted directly from the event information acquired from the information acquisition device 100. That is, survey conditions are set in advance for each person included in the group of survey subjects, and the specific person is extracted using information obtained by analyzing the event information. Therefore, even if the specific person extraction process is performed, there are cases where the specific person is not extracted.

[0032] The questionnaire data creation unit 305 creates questionnaire data for specific individuals. That is, questionnaire data is created for each specific individual. The wording of the questionnaire data is selected from predetermined ones. For example, a fixed phrase may be predetermined for each type of event. The wording of the questionnaire data may be created by a program using information obtained by analyzing the event information. The questionnaire data may be written in a format that presents options to make it easier to answer, or in a free-form format, or in a format that includes both.

[0033] The questionnaire data creation unit 305 also manages the destinations of the specified person as questionnaire destination information, and creates the questionnaire data by including the destinations corresponding to the specified person in the questionnaire data. The questionnaire destination information may be acquired from the manager terminal device 200, which is a terminal of the affiliated company, or from the specified person terminal device 400 that answers the questionnaire. The survey data may be in a format in which the survey is displayed in the body of the email, or in a format in which a URL (Uniform Resource Locator) is displayed that allows the survey to be viewed by clicking on the body of the email and accessing a server device (not shown).

[0034] When the survey server 300 is in emergency mode and receives a response to a survey, the safety status management unit 306 manages the content of the response as a safety status. The safety status may include at least either the content of the response or date and time information related to the survey or the response. The date and time information related to the questionnaire mentioned here includes the date and time when the questionnaire was created or sent, and the date and time information related to the responses mentioned here includes the date and time when the responses were received or sent.

[0035] In this way, when the safety status management unit 306 is not managing the safety status, it creates and manages a safety status when it receives a response. Also, when the safety status management unit 306 is managing the safety status and receives another response, it updates the safety status to that of the other response. In the emergency mode, if a response has not yet been received, no safety status is created. If the safety status is managed when creating a questionnaire, the safety status is used to create the questionnaire, i.e., part or all of the safety status is included in the questionnaire.

[0036] The safety status is created and stored by the safety status management unit 306 in emergency mode, but is not stored and is deleted when transitioning to normal mode. When the safety status is deleted, the information included in the safety status may be recorded, for example, as a log. When the mode transition instruction unit 204 (see FIG. 2) of the administrator terminal device 200 is operated, the mode transitions from emergency mode to normal mode. Therefore, the safety status is held until the survey implementation server 300 receives information indicating that the operation has been performed. In other words, the safety status is held until the mode transitions from emergency mode to normal mode.

[0037] The report data creation unit 307 creates report data based on the responses to the questionnaire sent by the specified person. The report data is sent to the administrator terminal device 200 as a report to the administrator via the transmission / reception unit 301. The report data can be created using the safety status of each specified person.

[0038] The functional configuration of the above-mentioned survey implementation server 300 is realized by a control unit comprising a CPU (Central Processing Unit) which is a computing device, a ROM (Read Only Memory) which stores the programs executed by the CPU, and a RAM (Random Access Memory) which is used as a working memory.

[0039] The information acquired by the survey server 300 via the transmitter / receiver unit 301 may be in the form of text, or may be in the form of non-textual video (e.g., images from a camera installed on a river), still images (e.g., satellite photographs), or audio. In such cases, the attribute management unit 303 assigns attributes to the information and manages it as attributes.

[0040] <Event Information> The event information referred to here is various types of crisis management information. Crisis management information here refers to information that is effective in preventing a crisis or mitigating its impact, where a planned action by an individual or organization is disrupted by some external factor. For example, when a manager in charge of crisis management at a company obtains crisis management information, he or she will conduct a questionnaire to check the safety of the company's employees and other persons subject to crisis management. In addition, the manager will provide the crisis management information to the persons subject to crisis management as necessary.

[0041] More specifically, the event information transmitted from the information acquisition device 100 to the survey implementation server 300 includes information indicating the type, time, region, and extent of the event. For example, in the event of an earthquake, the event information includes information indicating that an earthquake has occurred as the type of event, information indicating the time of the earthquake as the time of the event, and information indicating the epicenter as the region of the event. Furthermore, the event information includes information indicating the magnitude and depth of the epicenter as well as information indicating the seismic intensity of each region as the extent of the event. The method of determining the areas affected by an earthquake may be based on areas where a seismic intensity equal to or greater than a predetermined value is observed, or may be based on the epicenter, magnitude, depth of the epicenter, etc.

[0042] To explain further, the attributes of the event information managed and set by the attribute management unit 303 include, as multiple elements, some or all of the information indicating the area, level, category, and time of the acquired information, and may further include other information besides these.

[0043] The information indicating the area refers to information for identifying the area the acquired information pertains to, and specifies the geographical area (district). The information indicating the degree refers to information for identifying one of several predetermined stages, and specifies the level of urgency, seriousness, importance, etc. The information indicating the type refers to information indicating which of the predetermined categories the information belongs to, and the information indicating the time refers to information indicating the situation at what point in time. Furthermore, the other information can be set according to the acquired information.

[0044] For example, when information is acquired that an earthquake has occurred, information indicating the region includes the location of the epicenter and the region where the seismic intensity was detected, and information indicating the extent includes the magnitude indicating the scale of the earthquake and the seismic intensity indicating the magnitude of shaking in each region. Information indicating the type is "earthquake," and information indicating the time is the time the earthquake occurred. Other information may include, for example, whether a tsunami is expected due to the earthquake. Furthermore, when information is acquired that there is a possibility of a tsunami occurring following an earthquake, the information indicating the area includes the area where the tsunami is expected to arrive, the information indicating the extent includes the expected wave height for each area, the information indicating the type is tsunami, and the information indicating the time includes the expected time of the tsunami arrival. Other information includes whether or not the first wave will arrive. Furthermore, when information is acquired that a fire has broken out following an earthquake, the information indicating the area includes the location where the fire broke out, the information indicating the extent includes information indicating whether the building where the fire broke out is a detached house, an apartment building, or a factory, the information indicating the type is "fire," and the information indicating the time includes the time when the fire department was contacted. Other information may also include the possibility of the fire spreading.

[0045] The attributes are set by analyzing the acquired information, detecting the source of the information, and the circumstances under which the information was acquired. More specifically, the attribute management unit 303 sets information extracted from the acquired information as attribute information, or sets information input by an operator as attribute information.

[0046] To explain an example of attribute information, if the acquired information is information indicating the operational status of a train, such as the suspension of service on the Yamanote Line, the information indicating the area would be "Yamanote Line," the information indicating the severity would be, for example, "4" on a scale from "1" (the lightest) to "5" (the most severe), the information indicating the type would be "railway information," and the information indicating the time would be "September 9, 2021, 3:48 PM." The other information in this case would be, for example, "personal injury accident." The other information is not limited to one, and may be multiple. By providing multiple information, search accuracy can be improved. For example, in the above example, the other information may be "outside route" or "no prospect of resuming operation" in addition to "injury accident." The number of other information can be changed for each event information. The acquired information is stored in a storage means such as a nonvolatile memory, together with the set attribute information.

[0047] 4A, 4B, and 4C are diagrams explaining the information acquired by the survey server 300 in response to the occurrence of an earthquake, which is event information, and are shown in chronological order. In (a) to (c), a time axis running from top to bottom is set, and the acquired information is conceptually shown. Figure 4(a) shows the scene where the first earthquake information report is received. The first earthquake information report (breaking news) includes information indicating that an earthquake has occurred (earthquake information) and that the time of the earthquake is "8:△△," as well as information on the approximate epicenter, magnitude, and depth of the epicenter (preliminary or provisional values) (information on the seismic intensity at the epicenter). Such earthquake occurrence information is managed as information indicating the type, the time of earthquake occurrence as information indicating the time, the epicenter as information indicating the region, and the magnitude and depth of the epicenter as information indicating the degree.

[0048] Furthermore, earthquake information usually includes information on seismic intensity in various locations around the epicenter, but such information on seismic intensity in various locations is managed as other information. That is, the locations where the seismic intensity is indicated and the seismic intensity in various locations are managed in association with each other. The number of other information is not limited to one, and may be multiple.

[0049] Furthermore, the seismic intensity information for each location is not limited to being managed as other information. For example, each location for which seismic intensity is indicated may be managed as information indicating the region, and the seismic intensity for each location may be managed as information indicating the degree. In other words, multiple pieces of information indicating the region and information indicating the degree may be associated with earthquake information, which is information indicating the type. In this way, for one piece of information (e.g., information indicating type) from among information indicating type, information indicating area, information indicating degree, and information indicating time, some or all of the information other than the one piece of information (e.g., information indicating area, information indicating degree, and information indicating time) may be managed so as to correspond to the information.

[0050] Figure 4(b) shows a scene where the second earthquake report (detailed report) is obtained, and the first tsunami report is also obtained. When the second earthquake report is obtained, it is managed together with the first earthquake report that has already been obtained, as information of the earthquake information type. The second report was released at 8:00, and this time is managed as information indicating time. For this reason, earthquake information can be illustrated as columns extending in chronological order.

[0051] To explain further, the second report may include seismic intensity data from a wider range of locations than the first report, and may also include more accurate information on the epicenter and magnitude than the first report, and may also include more accurate information on the epicenter, magnitude, and depth than the first report. When the second report, which is an updated version of the first report, is obtained, the second report is not overwritten on the first report and managed, but the first and second reports are managed together in a linked manner.

[0052] The tsunami information in Figure 4(b) also includes the expected arrival time and expected height of the tsunami in each area, and if a tsunami warning or advisory is issued, it also includes information indicating which area the warning or advisory has been issued for. More specifically, the first tsunami information report includes information indicating the possibility of a tsunami occurring (tsunami occurrence possibility information) and the time the tsunami information was announced, which is "8:00 AM." It also includes information indicating the expected arrival time and height of the first wave in each area, as well as information indicating the issued warnings and advisories.

[0053] The tsunami occurrence possibility information mentioned here is managed as information indicating the type, and the time of tsunami information announcement is managed as information indicating the time. Also, each location is managed as information indicating the area, and information indicating warnings and advisories is managed as information indicating the level. Furthermore, information indicating the expected time of arrival of the first wave in each location and its height is managed as other information.

[0054] The acquired tsunami information differs from the earthquake information in the information indicating its type. For this reason, as shown in Figure 4(b), columns for tsunami information are added in addition to columns for earthquake information. However, the information indicating the time in the tsunami information is "8:00", which is after "8:00:00", and the columns for tsunami information are illustrated along the time axis, just like the earthquake information.

[0055] FIG. 4(c) shows a scene where the third earthquake information report and the second tsunami information report are received, as well as the first fire information report. The third earthquake information report was issued at 8:00 a.m., and is issued, for example, in the case of an earthquake that shakes a wide area, when the collection of seismic intensity information from various locations is not possible in time for the second report, or when the magnitude and depth of the first report are corrected through subsequent accurate calculations.

[0056] In addition to the distinction between first, second, and third reports for a single earthquake, there are also cases where an aftershock is followed by a main shock, which is then followed by another aftershock, and such distinctions may be made. In addition, while the mainshock and aftershocks may be managed in association with each other, they may also be managed independently. In the case of earthquake swarms, where multiple aftershocks occur in a single day, they may also be managed independently, in addition to being managed in association with each other.

[0057] The second report of tsunami information was issued at 8:00 AM, and if there is information about the possibility of a tsunami occurring, it includes information on the predicted arrival time and height of the first wave over a wider area than the first report. Furthermore, if the first wave has arrived, the second report includes information indicating the location and time of arrival, its height, etc. Depending on the situation, further tsunami information from the third report onwards is issued, and the survey implementation server 300 acquires it in sequence and manages the information.

[0058] Fire information is one of the disasters that occurred as a result of the earthquake, and is shown in a separate column from the columns for earthquake and tsunami information. The first fire report is issued at "8:XX" and includes information indicating the time of the fire call and the location of the fire. It may also include information indicating the type of fire, such as a structure fire (residential fire, building fire, factory fire, etc.), vehicle fire, forest fire, etc., and may also include information indicating whether or not there was an explosion.

[0059] In addition, the information acquired by the survey implementation server 300 may be in the form of text, or may be in the form of non-textual video (for example, images from a camera installed on a river), still images (for example, satellite photographs), or audio. In such cases, attributes are assigned and managed accordingly.

[0060] FIG. 5 is a flowchart showing an example of a processing procedure for managing attributes of event information in the attribute management unit 303 (see FIG. 3) of the survey implementation server 300. 5, when the transmitting / receiving unit 301 (see FIG. 3) of the survey implementation server 300 acquires event information from the information acquisition device 100 (see FIG. 1) (step 101), the attribute management unit 303 analyzes the attributes of the event information (step 102). This allows the system to determine whether the acquired event information is related to previously acquired event information.

[0061] Thereafter, the attribute management unit 303 determines whether there are any additions or changes to the attributes of the event information (step 103). If there are any additions or changes (Yes in step 103), the attributes are added or changed (step 104) and management is performed (step 105). If there are no additions or changes (No in step 103), management is performed using the acquired event information (step 105). The term "management" used here refers to associating related event information with already acquired event information based on the attributes of the event information, as explained in FIG.

[0062] Figure 6 shows the response status of employees A to H to the questionnaire when multiple events 11, 12, and 13 occurred. The time series is shown from left to right in Figure 6. A questionnaire is conducted for each of events 11 to 13 shown in Figure 6. An example of event 11 is the occurrence of the first earthquake as a disaster, an example of event 12 is the occurrence of a tsunami, and an example of event 13 is the occurrence of a fire or the occurrence of the next earthquake. Employees A to H are the recipients of the questionnaire and are the ones who respond to it.

[0063] As shown in FIG. 6, employee A's responses to the questionnaires for events 11 to 13 are all "safe," and the administrator can confirm that employee A is safe. Employee B's response to the questionnaire for event 11 is "safe," but his responses to events 12 and 13 are "injured," so the administrator can confirm that Employee B is injured. Employee C's response to the questionnaire for events 11 and 12 is "safe," but the response to event 13 is "injured," so the manager can confirm that Employee C is injured. Employees A to C responded to all three questionnaires.

[0064] Next, a case where a user has answered at least one of the three questionnaires but has not answered all of them will be described. Employee D's response to the survey for Event 11 is "safe," but there is no response to the survey for Event 12, which is "no response," while the response to Event 13 is "injured." Therefore, the administrator can confirm that Employee D is injured based on the latest information, despite the "no response." Employee E did not respond to the survey for Event 11, marking it as "No response," but his responses to Events 12 and 13 were "Safe," so the administrator can confirm that Employee E is safe based on the latest information. Employee F did not respond to the questionnaire for events 11 and 12, marking it as "no response," but his response to event 13 was "safe," so the administrator can confirm that, based on the latest information, Employee F is safe.

[0065] Employee G's response to the survey for event 11 was "injury," but he did not respond to the survey for events 12 and 13, leaving them as "no response." Therefore, the manager can confirm that Employee G was injured in the earthquake. Employee H did not respond to the questionnaire for events 11 and 12, marking it as "no response," but his response to the questionnaire for event 13 was "injury." Therefore, the manager can confirm that Employee H was injured, although it is unclear when he was injured.

[0066] In this embodiment, as shown in Figure 6, events 11 to 13 are associated with the safety status for events 11 to 13, so the administrator can use events 11 to 13 as a landmark to grasp the response status, including no response, of employees A to H, as well as their latest safety status. Furthermore, in this embodiment, since the safety status is updated, when the report data creation unit 307 (see FIG. 3) creates report data for such safety confirmation, the processing load is reduced by using the safety status.

[0067] FIG. 7 is a flowchart showing an example of a processing procedure for conducting a survey in the survey server 300. In the survey server 300, when the transmitter / receiver 301 (see FIG. 3) acquires event information from the information acquisition device 100 (see FIG. 1) (step 201), it determines whether to conduct a safety confirmation survey based on the event information (step 202). This determination can be made automatically by determining whether the event information satisfies predetermined conditions, or by displaying alert information including the event information on the display unit 205 (see FIG. 2) of the administrator terminal device 200, prompting the administrator to decide whether to conduct the survey based on the displayed content. If the administrator who has viewed the alert information decides to conduct the survey, he or she instructs the survey to be conducted by operating the device. If the survey is not to be conducted (No in step 202), the process ends.

[0068] If a survey is to be conducted (Yes in step 202), it is checked whether the system is in emergency mode (step 203). If the mode is the emergency mode (Yes in step 203), the specific person extraction unit 304 (see FIG. 3) identifies the recipients of the questionnaire based on the event information and using the implementation conditions previously instructed by the implementation condition acquisition unit 302 (step 205). The identification of the recipients is performed by the specific person extraction process by the specific person extraction unit 304 (see FIG. 3) described above or another specific person extraction process. If the mode is not emergency mode (No in step 203), the mode transitions to emergency mode (step 204), and the process proceeds to step 205. When the mode transitions to emergency mode, the safety status can be maintained by the safety status management unit 306 (see FIG. 3), and the safety status can be managed.

[0069] Next, the safety status management unit 306 (see FIG. 3) checks whether the safety status is being held (step 206). If the safety status is being held (Yes in step 206), the held safety status is read (step 207). The questionnaire data creation unit 305 (see FIG. 3) creates a questionnaire using the read safety status (step 208), and the transmitting / receiving unit 301 (see FIG. 3) sends the created questionnaire to the destination (step 209). The date and time of sending the questionnaire is stored together with the corresponding event information, the date and time of reception thereof, and the destination information.

[0070] The sending of the questionnaire in step 209 described above may be an email questionnaire in which an email containing the contents of the questionnaire is sent, or a web questionnaire in which the contents of the questionnaire are viewed by accessing a server device (not shown). In the case of a web questionnaire, a URL for accessing the server device (not shown) may be sent by email, or a predetermined application may be used to notify the recipient of the questionnaire. The sending of the questionnaire in step 215 described below is similar to that in step 209.

[0071] When the safety status management unit 306 (see FIG. 3) receives the responses to the questionnaire (step 210), it performs an update process to update the safety status (step 211). The update process (step 211) will be described later. If no response to the questionnaire is received, the update process (step 211) is not performed, and the process proceeds to step 212, which will be described later. In other words, if there is no response, the safety status is not updated.

[0072] After the update process (step 211), it is determined whether or not an emergency mode termination instruction has been issued from the mode transition instruction unit 204 (see FIG. 2) of the administrator terminal device 200 (step 212). If an instruction to end the emergency mode is given (Yes in step 212), the mode transitions to the normal mode (step 213), and the process ends. If there is no instruction to end the emergency mode (No in step 212), the process ends while remaining in the emergency mode.

[0073] On the other hand, if the safety status is not maintained (No in step 206), the questionnaire data creation unit 305 (see Figure 3) creates a normal questionnaire that does not use the safety status (step 214), and the transmission / reception unit 301 (see the same figure) sends it to the destination (step 215).

[0074] After the questionnaire is sent, it is determined whether a response has been received (step 216), and if a response has been received (Yes in step 216), the safety status management unit 306 (see FIG. 3) creates and stores a safety status (step 217). As described above, the safety status can include the content of the response and the date and time the response was received. Then, the process proceeds to step 212. If no reply has been received (No in step 216), no safety status is created and the process proceeds to step 212. In other words, if there is no reply, no safety status is created.

[0075] In this way, in emergency mode, the safety status obtained by receiving a response from the destination is created and stored as a safety status (step 217), and when a response is received (step 210) while the safety status is being stored (Yes in step 206), the safety status is updated to one based on the response (step 211).In emergency mode (Yes in step 203 or step 205), when event information is acquired (step 201), a questionnaire to be sent to the destination is created using the safety status stored for the destination (step 208). Here, the safety status is an example of safety information. The normal mode is an example of a first state, and the emergency mode is an example of a second state. Furthermore, the mode transition instruction unit 204 (see FIG. 2) is a part where an operation to instruct transition to the first state is performed.

[0076] Next, the update process (see step 211 in FIG. 7) will be described. FIG. 8 is a flowchart showing the update process in FIG. The update process shown in Fig. 8 is an example of a procedure when a questionnaire response is received (see step 210 in Fig. 7) in a case where the safety status is managed by the safety status management unit 306 (see Fig. 3) in emergency mode. The safety status is managed for each destination of the questionnaire.

[0077] The safety status management unit 306 (see FIG. 3) determines whether the current response received has changed from the previous response (step 301). If there is a change in the current response content (Yes in step 301), the safety status management unit 306 (see Figure 3) updates the safety status response content to the current response content (step 302) and also updates the safety status reception time to the time the current response was received (step 303). If there is no change in the content of this reply (No in step 301), the reception date and time of the safety status is updated to the time when this reply was received (step 303).

[0078] In this way, if there is a change in the content of the response this time (Yes in step 301), the response content and the date and time of receipt of the safety status are updated, whereas if there is no change (No in step 301), only the date and time of receipt of the safety status is updated. This allows the safety status to be kept up to date.

[0079] If no response to the questionnaire is received, the safety status will not be updated even if the safety status is managed, but this is not limited to this. For example, if a predetermined time has passed since the questionnaire was sent, or if the next event information is obtained, information indicating that no response was received from the destination can be recorded. By using this information regarding no response, the status of each employee can be grasped (see Figure 6), and data can also be compiled. The record of information on no response may be considered to be a log corresponding to the no-response questionnaire, not included in the safety status, but may also be included in the safety status. It is also possible to employ a method in which, when the questionnaire is sent, information indicating that the recipient has not responded is recorded, and information indicating that the recipient has responded when the recipient receives a response is rewritten.

[0080] The safety status is updated by overwriting the response content and the date and time of receipt to bring them up to date, but past history may also be included. Such past history is history in emergency mode, and includes event information that triggered the transition to emergency mode and subsequent event information. The response content and the date and time of receipt are associated with each piece of past event information. Furthermore, when information indicating no response is recorded, information indicating no response is associated with that event information.

[0081] Next, an example of a questionnaire created by the questionnaire data creation unit 305 (see FIG. 3) will be described. Note that although an example of a web questionnaire will be described below, it can also be applied to an email questionnaire.

[0082] 9 and 10 are diagrams illustrating examples of web surveys. Figure 9(a) is a web survey 31 about "earthquakes," Figures 9(b), (c), and (d) are a web survey 32 about "tsunamis" that occurred after "earthquakes," and Figures 10(a), (b), and (c) are a web survey 33 about "fires" that occurred after "tsunamis." The explanation will be given assuming that "earthquake," "tsunami," and "fire" in FIGS. 9 and 10 correspond to events 11 to 13 in FIG. 6 described above.

[0083] In each of the web surveys 31 to 33 in Figures 9(a) to (d) and Figures 10(a) to (c), "Mr. / Ms. ◎◎◎◎" is the specified person, the recipient of the survey, and the person answering the survey.

[0084] [Web Survey on Earthquake Occurrence 31] The web survey 31 shown in Figure 9(a) is conducted in response to the occurrence of an "earthquake" and includes an area 31a that displays the explanation "Please answer the survey about the earthquake that just occurred," an area 31b for checking safety, and an area 31h that displays a send button for submitting the survey responses.

[0085] The area 31b in FIG. 9(a) has the options for safety confirmation: "safe," "slight injury," and "severe injury." This allows the user to check whether or not there is an injury and the extent of the injury. Alternatively, the options may be limited to two: "safe" and "injured." Each item has a radio button. Each item is an exclusive option. Although not shown, some or all of the items may be configured as check boxes that allow any number of selections. In the case of the above-mentioned application, selection may be made using buttons displayed in the UI. 9(a) is created in a state where the safety status is not yet managed, even though the system is in emergency mode. That is, this is the case for employees A to H in FIG. 6.

[0086] [Web Survey on Tsunami Occurrence 32] The web survey 32 shown in Figure 9(b) is conducted in response to the "tsunami" that occurred after the "earthquake," and is composed of an area 32a that displays the explanation "Please answer the survey regarding the "tsunami" that just occurred," an area 32b for confirming safety, and an area 32h that displays a send button for submitting the survey responses.

[0087] 9(b), like FIG. 9(a), the area 32b has the options for safety confirmation, "safe," "slightly injured," and "severely injured," and radio buttons for each option. The stage at which the web survey 32 shown in Figure 9(b) is created is the same as in Figure 9(a), in that the system is in emergency mode but safety status is not being managed. More specifically, the stage at which the web survey 32 shown in Figure 9(b) is created is when no responses have been made to the web survey 31 (see Figure 9(a)) regarding "earthquakes." That is, this is the case for employees E, F, and H in Figure 6 described above.

[0088] The web survey 32 shown in Figure 9(c) is conducted in response to a "tsunami" after an "earthquake," just like the web survey 32 shown in Figure 9(b). On the other hand, unlike the web survey 32 shown in Figure 9(b), the web survey 32 shown in Figure 9(c) is conducted when responses were made to the web survey 31 (see Figure 9(a)) about an "earthquake."

[0089] The web survey 32 shown in Figure 9(c) is composed of an area 32a that displays the explanation "Please answer the survey about the tsunami that occurred just now," an area 32c for displaying the details of the safety status, an area 32d for confirming safety, and an area 32h that displays a send button for submitting the survey responses.

[0090] Area 32c in Figure 9(c) includes the content of the response to the questionnaire that has already been conducted (see Figure 9(a)) and the date and time of receipt of the response. That is, it includes the content of the response, "The response to the questionnaire about the earthquake was 'safe'," and the date and time of receipt of the response, "◇◇ month ◇◇ day ◇◇ hour ◇◇ minute." That is, it is the case of employees A to D in Figure 6 described above.

[0091] Area 32d in Figure 9(c) has options for safety confirmation, such as "No change," "Minor injury," and "Severe injury," along with radio buttons for each option, based on the content of the answer to the safety status. Since the answer to the "earthquake" questionnaire was "safe," "No change" means "safe."

[0092] To explain further, when answering the questionnaire about "tsunami," the answer you have already given can be confirmed in area 32c, so if you are still "safe," your answer this time will be "no change" in area 32d. Also, if you are not "safe" due to injury, your answer will be "changed," so your answer will be either "slight injury" or "severe injury" in area 32d. In this way, assuming the answer to the "earthquake" questionnaire is "safe," the answer to the "tsunami" questionnaire is whether there has been any change in area 32d. This reduces the burden on respondents when answering the questionnaire compared to when the questionnaire includes options such as area 32b of the web questionnaire 32 shown in Figure 9(b). Furthermore, in the "tsunami" questionnaire, the answers to the "earthquake" questionnaire that have already been returned are entered in area 32c, so those answering the questionnaire can recognize that their answers to the "earthquake" questionnaire have been conveyed to the administrator.

[0093] The web survey 32 shown in FIG. 9(c) asks users to indicate whether there has been any change. After users respond to the web survey 32, the safety status is updated as described above. One safety status is updated for each recipient in turn. This allows users to track changes in the situation over time for each recipient of the web survey. By updating the safety status in this way, the most recent safety status can be presented when creating the next questionnaire. More specifically, if no response has been received for the previous questionnaire, the response for the previous questionnaire is presented. In this way, the most recent received response can be presented when creating the next questionnaire.

[0094] The web survey 32 shown in Figure 9(d), like the web surveys 32 shown in Figures 9(b) and (c), is conducted in response to a "tsunami" after an "earthquake," and like the web survey 32 shown in Figure 9(c), it is conducted when responses are made to the web survey 31 (see Figure 9(a)) about an "earthquake."

[0095] The web survey 32 shown in Figure 9(d) is composed of an area 32a that displays the explanation "Please answer the survey about the tsunami that occurred just now," an area 32c for displaying the details of the safety status, an area 32e for confirming safety, and an area 32h that displays a send button for submitting the survey responses.

[0096] Area 32c in Figure 9(d) includes the content of the response to the questionnaire that has already been conducted (see Figure 9(a)) and the date and time of receipt of the response. That is, it includes the content of the response, "The response to the questionnaire about the earthquake was 'Minor injury'," and the date and time of receipt of the response, "◇◇ month ◇◇ day ◇◇ hour ◇◇ minute." This is the case of employee G in Figure 6 described above.

[0097] Area 32e in Fig. 9(d) has options for safety confirmation, "No change" and "Severe injury," and radio buttons for each option, based on the content of the answer to the safety status. Since the questionnaire for "earthquake" indicated "Minor injury," area 32e in Fig. 9(d) does not have an option for "safe," and "No change" means "Minor injury."

[0098] Consider a case where the answer to the questionnaire about "earthquake" is "slightly injured," but the web questionnaire 32 shown in Figure 9(d) does not reflect this answer and instead includes "safe" as an option. From the perspective of the person responding to the questionnaire, they must be careful not to mistakenly select the "safe" option, which can increase the burden of answering the questionnaire and can lead to doubts about the significance of answering the questionnaire, reducing their motivation to answer. This is all the more true when the person being asked to confirm their safety is, for example, someone who has been affected by an earthquake or other disaster. In this embodiment, the burden of answering the questionnaire can be reduced by providing options that reflect the responses to the question "earthquake" in area 32e of the web questionnaire 32 shown in Fig. 9(d). This can increase the response rate to the questionnaire and the accuracy of the responses, thereby facilitating the smooth operation of the system for confirming the safety of people through questionnaires.

[0099] [Web Survey on Fire Breakdown 33] The web survey 33 shown in Figure 10(a) is conducted in response to a "fire" that occurred after a "tsunami," and includes an area 33a that displays the explanation "Please answer the survey regarding the "fire" that just occurred," an area 33b for confirming safety, and an area 33h that displays a send button for submitting the survey responses.

[0100] The area 33b in FIG. 10(a) has options for safety confirmation, such as "safe," "slightly injured," and "severely injured," and radio buttons for each option. The stage at which the web questionnaire 33 shown in Figure 10(a) is created is a state in which the system is in emergency mode but safety status is not being managed at the time of the fire outbreak, i.e., the case of employee F in Figure 6 described above.

[0101] The web survey 33 shown in Figure 10(b) is conducted in response to a "fire" that occurred after a "tsunami," and includes an area 33a that displays the explanation "Please answer the survey regarding the "fire" that just occurred," an area 33c for displaying the details of the safety status, an area 33f for confirming safety, and an area 33h that displays a send button for submitting the survey responses.

[0102] Area 33c in Figure 10(b) includes the content of the response to the questionnaire that has already been conducted (see Figure 9(b)) and the date and time of receipt of the response. That is, it includes the content of the response, "The response to the questionnaire about 'tsunami' was 'safe'," and the date and time of receipt of the response, "◇◇ month ◇◇ day ◇◇ hour ◇◇ minutes." Area 33f in Figure 10(b) has options for safety confirmation, such as "No change," "Minor injury," and "Severe injury," along with radio buttons for each option, based on the content of the response to the safety status due to the tsunami. Since the response to the "tsunami" questionnaire was "safe," "No change" means "safe."

[0103] The web survey 33 shown in Figure 10(c) is conducted in response to a "fire" that occurred after a "tsunami," and includes an area 33a that displays the explanation "Please answer the survey regarding the "fire" that just occurred," an area 33c for displaying the details of the safety status, an area 33f for confirming safety, and an area 33h that displays a send button for submitting the survey responses.

[0104] Area 33c in Figure 10(c) includes the content of the response to the questionnaire that has already been conducted (see Figure 9(a)) and the date and time of receipt of the response. That is, it includes the content of the response, "The response to the questionnaire about the earthquake was 'safe'," and the date and time of receipt of the response, "◇◇ month ◇◇ day ◇◇ hour ◇◇ minutes."

[0105] It is also possible to include in area 33c a message indicating that the questionnaire regarding the "tsunami" that occurred after the "earthquake" was left unanswered. This allows those answering the questionnaire to understand whether or not the questionnaire regarding multiple disasters, namely the "earthquake," "tsunami," and "fire," has been answered, and the content of the answers, and prevents respondents from answering a questionnaire regarding a disaster other than the most recent one in the series.

[0106] More specifically, the destination of the web survey 33 shown in Figure 10(c) has received the web survey 31 about earthquakes and the web survey 32 about tsunamis, but the recipient has responded to the web survey 31 but not to the web survey 32. This is the case of employee D in Figure 6 described above. Therefore, the safety status stored in this case is the answer to the questionnaire about the "earthquake," and the answer to the questionnaire about the earthquake is reflected in the area 33g.

[0107] Area 33f in Figure 10(c) has the options for safety confirmation, "No change," "Minor injury," and "Severe injury," along with radio buttons for each option, based on the content of the response to the safety status due to the earthquake (area 33g in Figure 10(c)). Since the response to the "earthquake" questionnaire was "safe," "No change" means "safe."

[0108] Here, the safety status includes the safety status from the safety confirmation in areas 31b, 32b to 32e, 33b, and 33f, which are the contents of the responses to the web questionnaires 31 to 33, and the date and time of receiving the response, but the safety status can be updated in two ways: when both the safety status and the date and time of receiving the response are updated, or when only the date and time of receiving the response is updated. The former is when the safety confirmation remains unchanged, and the latter is when the safety confirmation has changed (for example, to serious injury).

[0109] The web questionnaires 31 to 33 are examples of questionnaires, and the date and time of receipt of the responses is an example of date and time information relating to the questionnaires or the responses.

[0110] As shown in Figures 9 and 10, when creating a questionnaire to be sent to a destination using the safety status held for the destination, the safety confirmation items are set based on the safety of the safety status. That is, based on the safety status, the presence or absence of injuries and, if there are injuries, the severity of the injuries are confirmed. Then, for example, the following questionnaire is created: The item that is the same as the safety status item is renamed to "No change" and displayed in the questionnaire (see FIG. 9(c), FIG. 9(d), FIG. 10(b) or FIG. 10(c)). Furthermore, if the safety status is "injured," items that mean "not injured" (for example, "safe") are not displayed in the questionnaire (see Figure 9(d)). Furthermore, if the safety status is "injured," items indicating less severe injuries will not be displayed in the questionnaire. For example, if there are three safety confirmation items, "mild injury," "moderate injury," and "severe injury," and the safety status is "moderate injury," "mild injury" will not be displayed in the questionnaire.

[0111] If there is an error in the safety confirmation answer given to the questionnaire, the safety status will be updated with the incorrect safety status. Therefore, the next questionnaire will contain an incorrect answer. For example, if you answer "slightly injured" even though you are "safe." In consideration of such a situation, it is conceivable to create a questionnaire so that when the next questionnaire is received and an incorrect answer is realized, if the answer differs from the current situation, the administrator is notified of this fact. For example, a possible variation is to include a free-form comment field in the questionnaire created using the safety status. [Explanation of symbols]
