Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
<System Configuration>
1 is a diagram showing an example of the configuration of an information providing system according to the present embodiment. The information providing system 10 includes an information acquiring device 100, an information providing server 200, and a terminal device 300. The information acquiring device 100 and the information providing server 200, and the terminal device 300 and the information providing server 200 are connected to each other via a network 400.

The type of network 400 is not particularly limited as long as it is a communication network used for data communication between each device, and it may be, for example, a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, etc. The communication lines used for data communication may be either wired or wireless, and a combination of these may be used. In addition, a gateway device, a router, or other relay device may be used to connect each device via multiple networks or communication lines.

In the configuration example shown in FIG. 1, the information acquisition device 100 is directly connected to the information providing server 200 via the network 400, 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 transmit it to the information providing server 200. In this case, location information related to the event to be detected may be stored in the relay server, which may then transmit the information acquired by the information acquisition device 100 to the information providing server 200.

<Configuration of Information Acquisition Device>
FIG. 2 is a diagram showing the functional configuration of the information acquisition device 100.
The information acquisition device 100 is a device that acquires information necessary for the information providing server 200 to provide information, and includes an information search unit 101 , an information receiving unit 102 , an attribute setting unit 103 , and a transmitting unit 104 .

The information search unit 101 searches for information from other servers connected via the network 400, and acquires information from the search results. In the case of various disasters, including natural disasters such as meteorological disasters, earthquakes, and volcanic eruptions, and man-made disasters such as train accidents and aviation accidents, for example, when new meteorological disaster information is posted on the Japan Meteorological Agency website, the posted information is acquired as earthquake information, tsunami information, weather information, etc. In addition, when an evacuation preparation order is issued on a local government website, when power outage information (information indicating areas with power outages) is posted on a power company website, or when railway information is updated on a railway company website, the posted information is acquired as evacuation information, lifeline information, and traffic information, respectively.

In addition, when damage information such as confirmation of employee safety, confirmation of damage to bases, and confirmation of damage to business partners is posted on a company's homepage, the information search unit 101 acquires the posted information as safety information, base information, and business partner information, respectively.
The safety information, base information, and business partner information may be obtained from questionnaire responses or received emails, or may be obtained from a social networking service (SNS) as described below.

The information search unit 101 is not limited to disaster information such as earthquake information, and may also acquire information other than disaster information through searches. For example, the information search unit 101 acquires information that has suddenly increased due to trend analysis on SNS, as information on communication system failures, incidents, accidents, etc. In addition, the information search unit 101 acquires, for example, information on events and seasonal products posted for tourism purposes on official regional websites, as regional information or tourism information.

The information receiving unit 102 receives information for determining whether a specific, predetermined disaster-related event has occurred. The information receiving unit 102 is connected to devices such as various sensors, cameras, microphones, etc.

The sensor connected to the information receiving unit 102 is a detection device that detects various information from an object or environment as a physical quantity. Various types of sensors may be used depending on the type of information to be detected. For example, a temperature sensor, humidity sensor, illuminance sensor, speed sensor, vibration sensor, etc. may be used alone or in combination. This allows various information to be obtained about a location or item set as a detection target, such as temperature changes, changes in water volume, and the presence or absence of damage or malfunction. The specific configuration of the sensor is specified depending on the object from which information is to be obtained, the type of information to be obtained, the type of event to be detected, etc.

The camera connected to the information receiving unit 102 is an imaging device that acquires images as information. The images acquired by the camera may be either video or still images, and may be set according to the object of shooting and the type of information to be acquired. When acquiring video, in addition to video data in a video format, a configuration may be used in which a set of time-series still image data captured at regular intervals is acquired. The images acquired by the camera are sent to the information providing server 200 as digital data. The camera may be of various configurations depending on the object of shooting and the environment of use. For example, it may be a fixed camera or a portable camera (handy camera). In addition, a wide-angle camera or a panoramic camera that acquires images of a wide surrounding space, or a group of multiple cameras that capture a specific object or place from various angles, may be used. Furthermore, in terms of the data format of the acquired image, it may be a digital camera that acquires images as digital images, or an analog camera that acquires images as analog images. In the case of an analog camera, the image acquired as an analog image is converted to digital data and output. The specific configuration of the camera is specified according to the environment or scene in which the video is collected, the constraints of the available equipment, etc.

The microphone connected to the information receiving unit 102 is a device that records sound (acoustic information) as information. Microphones with various characteristics and configurations may be used depending on the location to be recorded and the type of acoustic information. For example, when recording human voices or the operating sounds of a specific object, a microphone with high directivity and sound range characteristics that match the range of the voices or operating sounds is used. When recording the voices of people gathered in a certain area or environmental sounds, a microphone with omnidirectional or low directivity is used. The acoustic information recorded by the microphone is sent to the information providing server 200 as digital data. The microphone itself can be configured in various ways, such as a fixed microphone, a sound collecting microphone, or a microphone array with strong directionality. The specific configuration of the microphone is specified depending on the environment or scene in which the recording is performed, the constraints of the available equipment, etc.

The attribute setting unit 103 sets attributes for each piece of information acquired by the information search unit 101 and the information receiving unit 102. The attribute information, which is information on the set attributes, is a number of elements used when the user wishes to narrow down information, and it is possible to narrow down information by combining them.

The attributes set by the attribute setting unit 103 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.
The information indicating the area refers to information for identifying which area the acquired information pertains to, and is used to identify the geographical area (district). The information indicating the degree refers to information for identifying one of a number of predetermined stages, and is used to identify 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 a certain point in time. In addition, the other information is allowed to be set according to the acquired information.

As an 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, the possibility of a tsunami caused by the earthquake.

The attributes are set by analyzing the acquired information and detecting the source and circumstances of the information acquisition. More specifically, the attribute setting unit 103 sets information extracted from the acquired information as attribute information, or sets information input by an operator as attribute information.

To explain an example of attribute information, if the acquired information is information indicating the operation status of a railway such as the suspension of service on the Yamanote Line, the information indicating the area is "Yamanote Line", the information indicating the degree is, for example, "4" out of a range from the lightest "1" to the most severe "5", the information indicating the type is "railway information", and the information indicating the time is "September 9, 2021, 15:48". In this case, the other information is, for example, "personal injury accident".
The other information is not limited to one, and may be multiple. By providing multiple information, the 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 non-volatile memory, together with the set attribute information.

In this embodiment, the information acquisition device 100 is provided with the attribute setting unit 103, but this is not limited to the above. In other words, instead of the information acquisition device 100 being provided with the attribute setting unit 103, the information providing server 200 may be provided with the information acquisition device 100. Also, a configuration in which the information acquisition device 100 and the information providing server 200 each have the attribute setting unit 103 may be adopted.

The transmitting unit 104 realizes a communication function for transmitting the information acquired by the information searching unit 101 and the information receiving unit 102 to the information providing server 200. That is, the transmitting unit 104 transmits the acquired information to the information providing server 200 together with the attribute information.
The transmitting unit 104 may transmit to the information providing server 200 when a predetermined time condition is satisfied, or may transmit to the information providing server 200 when an attribute is set.

<Configuration of information providing server>
The information providing server 200 is a server that manages the information acquired from the information acquisition device 100, and provides information corresponding to a request from a user among the managed information to the terminal device 300 (see FIG. 1).
More specifically, the information is managed by the information providing server 200 using the attributes of the acquired information, so that the acquired information can be accumulated in a state where it is managed by a plurality of attributes.
A request from a user is made, for example, at the terminal device 300, using an attribute selected from a plurality of attributes. Provided information, which is information provided in response to the user request, is specified using the attribute selected by the user.
The information referred to here includes, for example, event information such as disaster information, and may also include information other than event information.

FIG. 3 is a diagram showing the functional configuration of the information providing server 200. As shown in FIG.
The information providing server 200 includes a transmission/reception unit 201, an acquired information analysis unit 202, an attribute management unit 203, a provision information identification unit 204, and a notification content creation unit 205. The transmission/reception unit 201 is an example of a receiving means and an example of a notification means. The attribute management unit 203 is an example of a management means.

The transmitting/receiving unit 201 of the information providing server 200 is a network interface that connects to the information acquiring device 100 and the terminal device 300 via the network 400 and exchanges data. The transmitting/receiving unit 201 receives event information from the information acquiring device 100, receives filtering conditions and the like from the terminal device 300, and transmits the filtering results, that is, the provided information, to the terminal device 300.

The acquired information analysis unit 202 analyzes the attributes of the event information received from the information acquisition device 100 by the transmission/reception unit 201, and determines whether or not the event information is related to already acquired event information.
Furthermore, the acquired information analysis unit 202 analyzes the received event information and checks the attribute information set by the attribute setting unit 103 of the information acquisition device 100. Then, the acquired information analysis unit 202 checks whether the attribute information of the event information is missing or can be added.

If the acquired information analysis unit 202 determines that the received event information is related to already acquired event information, the attribute management unit 203 manages the related event information in association with each other.
Furthermore, when the acquired information analysis unit 202 determines that the attribute information of the event information is insufficient or can be added, the attribute management unit 203 automatically sets the attribute information or sets the manually inputted content. The attribute management unit 203 may modify or change the attributes set on the information acquisition device 100 side.

The information to be provided identification unit 204 uses the filtering conditions to filter the event information whose attributes are managed by the attribute management unit 203, and identifies the information to be provided to the terminal device 300. The filtering conditions are transmitted from the terminal device 300.

The notification content creation unit 205 creates notification content to be sent to the terminal device 300 based on the provided information identified by the provided information identification unit 204. The notification content may be composed of text information, may include images or videos, may include audio, or may be audio only.

The functional configuration of the information providing server 200 described above is realized by a control unit that includes 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.

<Configuration of Terminal Device>
The terminal device 300 is a device that accesses the information providing server 200 and browses event information. The terminal device 300 is realized by, for example, a personal computer (PC), a so-called tablet terminal device, a smartphone, or other information terminal device that can be connected to the network 400. Note that, although a plurality of terminal devices 300 are connected to the network 400, only one terminal device 300 is shown in FIG. 1, and the other terminal devices 300 are not shown.

FIG. 4 is a diagram illustrating the configuration of the terminal device 300. As shown in FIG.
The terminal device 300 includes a control unit 301 , a transmission/reception unit 302 , a display control unit 303 , a display unit 304 , and an input reception unit 305 .
The control unit 301 controls the operation of the entire device, and is configured with a CPU, a ROM, and a RAM.
The transmitting/receiving unit 302 is a network interface that connects to the information providing server 200 via the network 400 and exchanges data with the information providing server 200. The display control unit 303 controls the screen displayed on the display unit 304.
The display unit 304 displays various screens under the control of the display control unit 303, and is realized by, for example, a liquid crystal display etc. The input accepting unit 405 accepts input operations by the user of the terminal device 300, and includes operation devices such as a keyboard, a mouse, a touch panel, etc. for the user to operate.

<Management and filtering of information in the information providing server 200>
5 is a diagram for explaining the information acquired by the information providing server 200 when an earthquake occurs, and (a), (b), and (c) are shown in chronological order. In (a) to (c), a time axis proceeding from top to bottom is set, and the acquired information is conceptually shown.
5A shows a scene where the first earthquake information report is received. The first earthquake information report (flash report) includes information indicating that an earthquake has occurred (earthquake occurrence information) and that the earthquake occurred at 8:△△, as well as the approximate epicenter, magnitude, and depth of the epicenter (flash report or provisional value) (information regarding seismic intensity at the epicenter).
Such earthquake occurrence information is managed as information indicating the type, and the earthquake occurrence time is managed as information indicating the time. The epicenter is managed as information indicating the region, and the magnitude and depth of the epicenter are managed as information indicating the degree.

Earthquake information also typically includes information on the seismic intensity of various locations around the epicenter, but this information on the seismic intensity of various locations is managed as other information. In other words, the locations where the seismic intensity is indicated are managed in association with the seismic intensity of each location. The number of other information items is not limited to one, and may be multiple.

In addition, the seismic intensity information of each region is not limited to being managed as other information. For example, each region where the seismic intensity is indicated may be managed as information indicating the region, and the seismic intensity of each region 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 any one of information indicating a type, information indicating a region, information indicating a degree, and information indicating a time (e.g., information indicating a type), some or all of the information other than the one piece of information (e.g., information indicating a region, information indicating a degree, and information indicating a time) may be managed so as to be associated with multiple pieces of information.

5B shows a scene in which the second report (detailed report) of earthquake information is obtained and the first report of tsunami information is also obtained. When the second report of earthquake information is obtained, it is managed together with the first report of earthquake information already obtained as information of the type earthquake information.
The time when the second report was released is "8:00," and this time is managed as information indicating time. Therefore, earthquake information can be illustrated by columns extending in chronological order.

To explain further, the second report may include seismic intensities over a wider area 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 first and second reports are managed together in a linked manner, rather than the second report being overwritten on the first report.

The tsunami information in FIG. 5(b) also includes the expected time of arrival in each area and the expected height of the tsunami, as well as information indicating for which areas a tsunami warning or advisory has been issued if one has been issued.
More specifically, the first report of tsunami information includes information indicating the possibility of a tsunami occurring (tsunami occurrence possibility information) and information indicating the time the tsunami information was announced as "8:00." It also includes information indicating the expected time of arrival of the first wave in each area and its height, and information indicating the issued warnings and advisories.

The information on the possibility of a tsunami occurring referred to here is managed as information indicating the type, and the time when the tsunami information is released is managed as information indicating the time. Additionally, each location is information indicating the region, 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.

The acquired tsunami information differs from the earthquake information in the information indicating its type. For this reason, as shown in FIG. 5(b), columns of tsunami information are added in addition to the columns of earthquake information. However, the information indicating the time in the tsunami information is "8:00", which is after "8:00:00", and the columns of tsunami information are illustrated along the time axis, just like the earthquake information.

FIG. 5C shows a scene in which the third report of earthquake information and the second report of tsunami information are received, as well as the first report of safety information.
The third earthquake information report was issued at 8:00 a.m. and is issued, for example, in cases where the collection of seismic intensity information from various locations is not possible in time for the second report in the case of an earthquake that shakes a wide area, or when the magnitude and depth of the first report are revised based on subsequent accurate calculations.

In addition to categorizing earthquake information as a first, second, or third report for a single earthquake, there may be cases where an aftershock is followed by a main shock, which is followed by another aftershock, and such distinctions may be made. In addition to cases where the mainshock and aftershocks are managed in association with each other, they may also be managed independently. In the case of earthquake swarms, where there are multiple aftershocks in a single day, they may be managed independently in addition to being managed in association with each other.

The second report of tsunami information was issued at 8:◎◎ and, in cases where there is information indicating the possibility of a tsunami occurring, includes information on the expected 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. If further tsunami information is announced from the third report onwards depending on the situation, it is sequentially acquired by the information providing server 200 and the information is managed.

The safety information is information that confirms the safety of, for example, company employees after an earthquake or tsunami occurs, and can be obtained automatically, for example, from the results of responses to a questionnaire sent by the company to employees, or it can be obtained by manual input by a user based on email reports from employees. Such manual input can be performed by the information providing server 200, or it can be configured to be performed by the terminal device 300, or it can be configured to be performed by the information acquiring device 100.

Safety information is shown in a separate cylinder from the earthquake and tsunami information cylinders.
The first safety information report includes information indicating the safety confirmation (safety confirmation information) and information indicating that the time the safety confirmation information was obtained was "8:xx". It also includes information indicating the name of the person who confirmed the safety and the result of the safety confirmation. The result of the safety confirmation may be whether or not the person is safe, or whether or not there is any injury (minor injury/serious injury) and the degree of injury.

The safety confirmation information is managed as information indicating the type, and the time of acquisition is managed as information indicating the time. Furthermore, if there is information indicating the residential or working area or location corresponding to the safety confirmation name, that information is managed as information indicating the area. Furthermore, the presence or absence of injuries, which are the results of the safety confirmation, is managed as information indicating the severity.

In addition, the name of the safety confirmation and information indicating the result are managed as other information. Furthermore, if there is information that associates the name with an affiliation within an organization, the information indicating the affiliation within the organization may also be managed as other information. Furthermore, if the safety information includes a message, the message may be managed as other information.

In this way, safety information is managed by the time it was obtained. However, unlike the earthquake and tsunami information described above, this information is obtained relatively frequently, so the safety information provided in follow-up reports from the second report onwards may be managed based on a predetermined time interval.
If the predetermined time is, for example, 15 minutes, safety information obtained up to 15 minutes after the time of obtaining the first report will be considered the second report, and safety information obtained between 15 minutes and 30 minutes after the time of obtaining the first report will be considered the third report, and so on. In this way, safety information from the second report onwards is managed in 15-minute intervals.

In addition to the information acquired by the information providing server 200 being textual, it may also be in the form of non-textual video (e.g., images from a camera installed on a river), still images (e.g., satellite photos), or audio. In such cases, attributes are assigned and the information is managed by the attributes.

6A and 6B are flowcharts showing an example of a processing procedure of the information providing server 200, in which (a) shows a case where event information is managed, and (b) shows a case where event information is narrowed down. Narrowing down of event information is performed based on attribute information of events.
In the processing example shown in Fig. 6(a), when the transmitting/receiving unit 201 (see Fig. 3) of the information providing server 200 acquires event information from the information acquiring device 100 (see Fig. 1) (step 101), the acquired information analyzing unit 202 (see Fig. 3) analyzes the attributes of the event information (step 102). This makes it possible to determine whether the acquired event information is related to already acquired event information.

Thereafter, the attribute management unit 203 (see FIG. 3) judges whether or not there are additions or changes to the attributes of the event information (step 103). If there are additions or changes (Yes in step 103), the attributes are added or changed (step 104) and managed (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 described with reference to FIG.

In the processing example shown in FIG. 6(b), when the transmitting/receiving unit 201 (see FIG. 3) of the information providing server 200 receives the narrowing down conditions from the terminal device 300 (see FIG. 1) (step 111), the provided information identifying unit 204 (see FIG. 3) narrows down the event information based on the narrowing down conditions (step 112). The narrowing down conditions include area conditions, degree conditions, type conditions, time conditions, and other conditions that correspond to the attributes of the event information.

As described above, the method of narrowing down the search results using the narrowing down conditions is performed by the provided information identification unit 204 (see FIG. 3). Conceptually, cross-sectional information is created using the time condition among the narrowing down conditions, the type of the cross-sectional information is narrowed down using the type condition, and the information is further narrowed down using the area condition, the degree condition, and other conditions. The information narrowed down in this way can be called cross-sectional information.

Based on the narrowing down results, the notification content creation unit 205 (see FIG. 3) creates the notification content (step 113). The created notification content is output by the transmission/reception unit 201 to the terminal device 300 (step 114).

Then, the transmission/reception unit 201 determines whether there is an instruction from the terminal device 300 to change the filtering conditions (step 115), and if there is a change (Yes in step 115), the transmission/reception unit 201 returns to step 112 to perform filtering, etc., using the changed filtering conditions. If there is no change (No in step 115), the processing ends.

<Examples of management and filtering>
7 is a conceptual diagram showing an example of classification of various types of information acquired before and after an earthquake occurrence. In other words, the acquired various types of event information are conceptually shown as cylinders as coherent information associated with each other by attributes.
7, nine columns are shown, including a column 11 of earthquake information, and the other columns are omitted. That is, a column 12 of tsunami information is shown next to the column 11 of earthquake information, followed in order by a column 13 of weather information, a column 14 of evacuation information, a column 15 of lifeline information, a column 16 of traffic information, a column 17 of safety information, a column 18 of base information, and a column 19 of business partner information. In this way, the acquired information is displayed three-dimensionally by type.

7, the order of arrangement of the cylinders 11 to 19 is specified for each predetermined category, and the order is determined based on the information indicating the type. However, the arrangement of the cylinders may be selected by the user, or the order may be determined based on the order in which the first reports were obtained.
The positions of the columns 11 to 19 on the time axis are determined based on information indicating time. More specifically, the meteorological information column 13 and the traffic information column 16 were obtained before the first earthquake information report, and may be follow-up reports rather than the first report. The lifeline information column 15 is the first report after the occurrence of the earthquake.

In Figure 7, earthquake information is shown by a single column 11, but if multiple earthquakes occur, a column is shown for each earthquake, rather than just one. For example, if there is one aftershock after the main shock, the column for the aftershock is shown separately from the column for the main shock. Also, if there are multiple aftershocks, each aftershock is shown with its own column.

Although FIG. 7 shows one meteorological information column 13, since there are multiple types of meteorological information, such as heavy rain information and landslide warning information, a column of heavy rain information and a column of landslide warning information (not shown) may be shown together with or in place of the meteorological information column 13. Furthermore, when heavy rain information and landslide warning information extracted from the meteorological information are shown separately together with the meteorological information, the column of heavy rain information and the column of landslide warning information may each be shown extending in a spiral around the periphery of the meteorological information column 13.

The time axis shown in FIG. 7 is a time axis of hours, minutes, and seconds, in which case information showing a situation that changes from moment to moment is cut at any time to generate cross-sectional information, but this is not limited to this. For example, the time axis may be a week divided into days of the week from Monday to Sunday. In such a case, cross-sectional information can be formed for each day of the week.

The multiple cylinders shown in FIG. 7 may be, but are not limited to, stored information for multiple users. By managing the acquired information for each user, information customized for each user may be managed, and cross-sectional information for each user may be formed.

In the example shown in FIG. 7, the acquired information is shown divided into cylinders extending in the time axis direction for each type of information, but this is not limited to this and may be shown in a columnar shape other than a cylinder. Also, while the example shown in FIG. 7 shows cylinders of the same shape, information may be shown in different columnar shapes depending on the type of information. Furthermore, while the example shown in FIG. 7 shows cylinders with the same outer diameter, information may be shown in cylinders with different outer diameters depending on the type of information, or information may be shown in cylinders with different outer diameters depending on the importance of the information.

8 is a diagram for explaining cross-sectional information of event information, where (a) shows a time point 60 minutes after the occurrence of an earthquake, and (b) shows a time point 120 minutes after the occurrence of an earthquake. When various types of acquired event information are conceptually represented as a cylinder as coherent information associated with each other by attributes, the cross-sectional information of event information referred to here refers to information corresponding to a circular cross section obtained by cutting the cylinder at a certain position (time).
8(a) includes information corresponding to the cross sections of the earthquake information cylinder 11, the tsunami information cylinder 12, the weather information cylinder 13, the lifeline information cylinder 15, the traffic information cylinder 16, the safety information cylinder 17, and the base information cylinder 18. The cross section information 60 minutes after the occurrence of the earthquake does not include information corresponding to the cross sections of the evacuation information cylinder 14 and the business partner information cylinder 19.
Since the summary is created based on such cross-sectional information, evacuation information and business partner information will not be displayed in the summary if it is 60 minutes after the occurrence of an earthquake.

Furthermore, the cross-sectional information shown in FIG. 8( b ) includes information corresponding to the cross sections of the earthquake information cylinder 11, the tsunami information cylinder 12, the evacuation information cylinder 14, the lifeline information cylinder 15, the traffic information cylinder 16, the safety information cylinder 17, the base information cylinder 18 and the business partner information cylinder 19, but does not include information corresponding to the weather information cylinder 13.
In this way, information included in the cross-sectional information at one time point may not be included in the cross-sectional information at another time point. In other words, the position of the time axis determines which type of information is included in the cross-sectional information. More specifically, the position of the time axis determines whether the first report or the second report is included.

8 shows a case where a cylinder extending in the direction of the time axis is divided by information indicating the type and cut by time, but this is not limited to this and it may be cut by any of the attributes. That is, the attributes of the event information are used not only to classify the event information but also as an element for cutting the cross section, i.e., an element for narrowing down the search.
Also, in FIG. 8, the data is divided by type and time axis, but this is not limiting, and other combinations of elements, such as region and type, may be used.

Although FIG. 8 shows an example of cross-sectional information cut at a certain time, the present invention is not limited to this example, and cross-sectional information may be cut at a time range with a beginning and an end. For example, by creating cross-sectional information for each day over a time range of 10 days from the occurrence of an earthquake, summary information when viewed from a broad perspective can be generated.

FIG. 9 is a diagram illustrating a narrowing-down condition input screen displayed on the display unit 304 of the terminal device 300. As shown in FIG.
The display unit 304 shown in FIG. 9 displays a screen for inputting the narrowing down conditions received by the information providing server 200 in step 111 in FIG. 6B, and shows items that can be input.

The items that can be entered correspond to attributes, and are type, time, area, and degree, as well as other conditions. An add button 31 is provided for other conditions, and pressing the add button 31 causes items for the other conditions to be added and displayed. This allows multiple other conditions to be entered.

When the input operation of specifying values for the necessary items is completed, pressing the execute narrowing button 32 transmits the narrowing conditions to the information providing server 200. More specifically, the information input in the type item in Fig. 9 is transmitted as the type condition of the narrowing conditions. Furthermore, the information input in the time item is transmitted as the time condition of the narrowing conditions. The information input in the area and degree items is transmitted as the area condition and degree condition, respectively, and the information input in the other condition items is transmitted as the other conditions.
The type condition is information indicating a type of a plurality of attributes, the time condition is information indicating a time, and the area condition, the degree condition, and the other condition are information indicating an area, information indicating a degree, and other information, respectively.
In the example display shown in FIG. 9, the add button 31 is provided for other conditions, but the present invention is not limited to this and may be provided for other items.

FIG. 10 is a diagram illustrating a refined result display screen displayed on the display unit 304 of the terminal device 300, where (a) is one example and (b) is another example.
In the example shown in Fig. 10(a), "Summary screen 1/n after 60 minutes" is displayed on the display unit 304. This indicates that the summary screen is displayed when the time in the narrowing-down conditions is 60 minutes after the occurrence of an earthquake.
The summary screen also shows that the contents span n pages (n is a natural number equal to or greater than 2), and that the displayed page is the first page.
In order to display the remaining summaries, the next display button 33 is pressed.

As described above, in the example shown in FIG. 10A, the time condition is narrowed down to 60 minutes after the occurrence of the earthquake.
In one example, the search is not narrowed down by type conditions, and all types are displayed on the display unit 304. That is, as shown in Fig. 10(a) , earthquake information, tsunami information, weather information, and lifeline information are displayed on the first page of the summary. Traffic information, safety information, and base information (see Fig. 8(a) ) are displayed on the second and subsequent pages.
Furthermore, in one example, the search results are narrowed down by one or more combinations of area conditions, degree conditions, and other conditions.
In one example, when the search is narrowed down by at least a time condition and a region condition, one of the time condition and the region condition is an example of a first attribute, and the other is an example of a second attribute.

If the user wishes to change the filtering conditions and perform filtering again, the user presses the filter condition change button 34 (see Yes in step 115 in FIG. 6(b)). In other words, by changing the values specified in the items on the filter condition input screen (see FIG. 9), the user can perform filtering with different content.

Note that information that is not included in the cross-sectional information after 60 minutes is not displayed as a summary, but it may be possible to clearly indicate which information is not included in the cross-sectional information among the information indicating the type.

In another example shown in Fig. 10(b), a "Summary screen after 60 minutes" is displayed on the display unit 304 of the terminal device 300. The other example in Fig. 10(b) is the same as the example in Fig. 10(a) in that it is a summary screen after 60 minutes, but differs from the example in which the summary is one page, which is n pages.
More specifically, in another example, earthquake information is input in the type field of the refinement condition input screen (see FIG. 9 ), and the type condition is earthquake information. Also, the time condition is 60 minutes after the earthquake occurs. Therefore, only the earthquake information from the cross-sectional information 60 minutes later (see FIG. 8( a )) is included in the summary. In another example, either the type condition or the time condition is an example of a first attribute, and the other is an example of a second attribute.
In the other examples, similarly to the first example, when narrowing down the search results again by changing the narrowing down conditions, the button 34 for changing the narrowing down conditions is pressed.

In this manner, in this embodiment, the information providing server 200 acquires event information from the information acquisition device 100 (see FIG. 1), manages/narrows the acquired event information by attributes, and notifies the user of the narrowed-down results as summarized information or cross-sectional information from the terminal device 300. This makes it possible to ensure the accuracy of narrowing down the conditions required by the user for event information that may be updated at different times and frequencies. It also makes it possible to provide summarized information on an individual basis.

The refined result display screen shown in Figs. 10(a) and (b) is displayed on the display unit 304 by the display control of the display control unit 303 (see Fig. 4) in the terminal device 300 that received the notification content, and is composed of text. However, this is not limited to this. For example, an image other than text, such as that shown in Fig. 8, may be displayed, and when the mouse pointer is placed over a circular portion that is the cross-sectional information, the corresponding refined result may be displayed.

Here, the acquired information that the information providing server 200 acquires from the information acquisition device 100 is not limited to event information such as disaster information.
When the acquired information is, for example, an SNS, any trend situation can be generated by narrowing down the information by attributes at any timing and generating cross-sectional information.

In addition, if the acquired information is tourist information and cross-sectional information is generated by narrowing down the information by attributes at any time, it can be generated as arbitrary tourist information and can be used in combination with, for example, a set of itineraries.
Furthermore, if the acquired information is event information such as local events and other such activities, and cross-sectional information is generated by narrowing down the information by attributes at any time, it can be generated as any event information, and can be used in combination with online travel product applications, etc.

Furthermore, if the acquired information is restaurant information and cross-sectional information is generated by narrowing down the information by attributes at any time, it can be generated as arbitrary gourmet information and can be used in combination with, for example, a navigation app.
Furthermore, if the acquired information is news information and cross-sectional information is generated by filtering the information by attributes at any time, it can be generated as any online newspaper media. For individual users, news at a certain time, for example 13:00, in areas of their interest, such as politics or sports, can be provided as summary information.

In addition, if the acquired information is sensor data, etc., and cross-sectional information is generated by filtering by attributes at any time, it can be generated as a regular measurement table of your choice, and can be generated as a database for realizing a digital twin that reproduces real space in a virtual space.

Such acquired information may be updated at different times and with different frequencies. By managing multiple attributes associated with such information and notifying the user of information obtained by identifying the information based on at least two attributes selected by the user, it is possible to ensure the accuracy of narrowing down the conditions requested by the user.

The acquired information may be sensor information or unique data owned by the user. In such a case, for example, the acquired information acquired from the terminal device 300 may be managed in conjunction with the acquired information acquired from the information acquisition device 100. For example, the information providing server 200 may acquire sensor information indicating whether a factory's equipment system is operating or not and combine this information with other information to confirm that the factory's equipment system was operating even after an earthquake occurred.

FIG. 11 is a diagram illustrating a refined result display screen displayed on the display unit 304 of the terminal device 300. As shown in FIG.
In the display screen shown in the figure, a "summary screen" and a "chronological display" are displayed on the display unit 304. Also, on the display unit 304, a time series table 35 having vertical and horizontal directions is displayed.

Items are arranged horizontally in the time series table 35. These items include the date and time when the narrowing down was performed, as well as items that can be input as narrowing down conditions, such as type, time, area, degree, and other conditions (see FIG. 9). In the example shown in FIG. 11, types include earthquake information, tsunami information, weather information, etc. (see FIG. 10(a)).

The summaries of the filtered results are arranged in chronological order vertically in the time series table 35. The chronological order here means that the summaries are arranged in the order of the time when the filtering was performed using the filtering conditions, and it is possible to select either ascending order, which sorts the summaries from oldest to newest, or descending order, which sorts the summaries from newest to oldest.

In this manner, the display unit 304 shown in FIG. 11 is in a table format in which the horizontal axis indicates the narrowing-down conditions and the cross-sectional information based on the narrowing-down, and the vertical axis indicates the time axis.
More specifically, the output format in Fig. 11 is different from that in Fig. 10. That is, in the display unit 304 in Fig. 10, only the summary most recently filtered by the filtering conditions is displayed, and when the next filtering is performed, the display contents are replaced. That is, the summaries for one filtering are sequentially switched and displayed, thereby updating.
In contrast, in the display unit 304 in Fig. 11, past narrowing results are displayed in chronological order, and when the next narrowing is performed, the information is provided in a format in which the narrowing result is added. In other words, the display unit 304 in Fig. 11 shows a summary in a table format as a log of the narrowing results. Therefore, it is possible to check what happened when and where across multiple narrowing results in the summary.

As shown in FIG. 11, a save button 36 is displayed on the display unit 304, and the user can save the data in the time series table 35 by pressing the save button 36 as necessary. Note that the data may be automatically saved at regular intervals, or automatically saved when a refinement result is added.

In addition, in the display unit 304 shown in FIG. 11, conditions may be specified to perform data extraction. For example, earthquake information and the Chugoku region are combined to perform data extraction, and only the summaries of the extracted data are displayed in chronological order on the display unit 304. Also, by combining earthquake information and Hokkaido to perform data extraction, different summaries are displayed in chronological order on the display unit 304.

In addition, in the display unit 304 shown in FIG. 11, the items to be displayed may be selected, and the selected items may be displayed while the non-selected items may not be displayed. Also, it may be possible to perform a text search on the summaries, and the narrowed-down results including summary items that are hit in the text search results may be displayed in chronological order.

In this way, the narrowed-down results are organized so that the entire result can be seen at a glance, making it easy to view and access the required information. In addition, because it is in a table format, it is possible to quickly access the desired information by performing a text search within the time series table 35.

FIG. 12 is a diagram illustrating a comparison result display screen displayed on the display unit 304 of the terminal device 300. As shown in FIG.
The display screen shown in Fig. 12 displays cross-sectional information resulting from narrowing down the event information in a different manner from that shown in Fig. 11 above, and is a comparison result display screen 37 showing the results of comparing two summaries that differ along the time axis. This notifies the user of how the narrowed-down event information is changing along the time axis.

More specifically, the comparison result display screen 37 shows the result of comparison of cross-sectional information when the event information is narrowed down by combining a time condition with one or more conditions other than the time condition, such as a type condition, a region condition, a degree condition, or other conditions. As an example, the result here is a comparison between the above-mentioned Figures 8(a) and (b).
Either the time condition or the condition other than the time condition is an example of a first attribute, and the other is an example of a second attribute. "60 minutes after the occurrence of the earthquake" in Fig. 8(a) is an example of first time information, and the cross-sectional information is an example of specification using the first time information. "120 minutes after the occurrence of the earthquake" in Fig. 8(b) is an example of second time information, and the cross-sectional information is an example of specification using the second time information.

The comparison result display screen 37 will now be described in more detail.
The comparison result display screen 37 has display areas 37a and 37b arranged in two upper and lower stages. The upper display area 37a is an area for displaying information held by the user, and the lower display area 37b is an area for displaying information held by the party providing the service to the user. More specifically, the display area 37a displays, for example, safety information, base information, business partner information, etc., while the display area 37b displays, for example, earthquake information, tsunami information, weather information, evacuation information, lifeline information, traffic information, etc.

In the example shown in FIG. 12, the display area 37a includes an area 41 showing "personal impact," an area 42 showing "base impact," and an area 43 showing "issues." The display of the display area 37a allows the user to understand the status of responses to the questionnaire, etc.

In the area 41 showing "human impact," the start time and elapsed time are shown, and the "response rate" of the safety confirmation is shown as a percentage. The safety confirmation is also divided into the categories of "no response," "injury, etc.", and "safe," and a number display section 41a is displayed showing the number of cases relative to the total and the percentage for each category. Furthermore, a graph display section 41b using a bar graph, i.e., a 100% stacked bar graph, is displayed in area 41 to show the difference as a comparison result of the safety confirmation, thereby improving the visibility.

In addition to the numerical display, an arrow mark 47, which is information showing changes over time, is displayed in each of the items "Response rate,""Not responded to,""Injuries,etc.", and "Safe" in the area 41. The arrow mark 47 is a symbol indicating one direction, and the user can be notified of the status of the change depending on the direction the arrow is pointing.
The change status referred to here is indicated by an upward arrow indicating an "increase", a downward arrow indicating a "decrease", and a rightward arrow indicating "no change".

Instead of the arrow mark 47 shown in the area 41, another type of arrow mark, a hand mark with an extended index finger and curled fingers, or a triangular mark may be used to indicate upward, downward, or rightward orientation. Also, the orientation may be diagonally upward, diagonally downward, or rightward.
The arrow mark 47 may be displayed in a different color depending on the direction it is pointing, or the amount of change may be indicated by the size, line thickness, color, etc. of the arrow mark 47.

The area 42 showing "base impact" shows the start time and elapsed time as in the case of the above-mentioned area 41, and also shows "Affected (small scale)" as the "base impact" for status confirmation. Area 42 also divides status confirmation into categories of "Affected (large scale)", "Affected (medium scale)", "Affected (small scale)", and "Under confirmation", and shows the number of cases for each category, including 0. Also, for items with one or more cases, an overview of the item may be displayed.
Although the graph display portion 41b of the area 41 is not displayed in the area 42, it may be displayed. Moreover, although the arrow mark of the area 41 is not displayed in the area 42, it may be displayed.

In the area 43 showing "tasks", the start time and elapsed time are shown as in the case of the above-mentioned area 41, and the "status" of the task is shown as a percentage. Furthermore, the tasks are divided into the categories of "not yet addressed", "in progress", and "completed", and for each category, a number display section 43a is displayed showing the number of tasks relative to the total and the percentage of those tasks. Furthermore, a graph display section 43b for the tasks is displayed in area 43, and an arrow mark 47 is also displayed.

The display area 37b shown in FIG. 12 includes an area 44 showing the "external situation (alert type)," an area 45 showing the "external situation (occurrence type)," and an area 46 showing the "base incident situation." This allows the user to understand how much event information is available.

These areas 44 to 46 are divided into the categories of "occurrence/continuation" and "restoration/cancellation" and show the number of cases for each category. Areas 44 and 45 show the corresponding event information and the number of "occurrence/continuation" and "restoration/cancellation" cases for each event information. Area 46 is divided into specific categories of base incident status and shows the number of "occurrence/continuation" and "restoration/cancellation" cases for each category.
Furthermore, in the areas 44 to 46, an arrow mark 47 indicating a change over time is displayed.

The comparison result display screen 37 has tabs 37c for switching the display. Tabs 37c can be set by the user, and in the example shown in FIG. 12, each of the bases or facilities including the user's head office ("Head Office", "East Japan Branch", etc.) and all of them ("Entire Company") are set. The user can display the required content on the comparison result display screen 37 by selecting tab 37c.

As described above, the information processing device of this embodiment includes a receiving means for receiving event information from an information acquisition device, a management means for managing a plurality of attributes associated with the event information, and a notification means for notifying a result obtained by identifying the event information based on at least a first attribute and a second attribute selected by a user from among the plurality of attributes.
In addition, the program related to this embodiment enables the information processing device to realize a receiving function for receiving event information from the information acquisition device, a management function for managing multiple attributes associated with the event information, and a notification function for notifying the result obtained by identifying the event information based on at least a first attribute and a second attribute selected by a user from among the multiple attributes.
Furthermore, the information processing method according to this embodiment includes a receiving step of receiving event information from the information acquisition device, a management step of managing a plurality of attributes associated with the event information, and a notification step of notifying a result obtained by identifying the event information based on at least a first attribute and a second attribute selected by a user from among the plurality of attributes.
