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 a configuration example of an information providing system according to this embodiment. The information providing system 10 includes an information acquisition device 100, an information providing server 200, and a terminal device 300. The information acquisition device 100 and the information providing server 200, and the terminal device 300 and the information providing server 200 are connected via a network 400, respectively.

The type of network 400 is not particularly limited as long as it is a communication network used for data communication between devices, and may be, for example, a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, or the like. The communication line used for data communication may be wired or wireless, and both may be used in combination. Alternatively, a relay device such as a gateway device or a router may be used to connect each device via a plurality of networks or communication lines.

Note that 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 a so-called edge server is interposed, and each piece of information is acquired by this relay server. A configuration may also be adopted in which information acquired by the device 100 is collected and transmitted to the information providing server 200. In this case, position information related to the event to be detected may be held in the relay server, and the relay server may transmit it to the information providing server 200 together with the information acquired by the information acquisition device 100.

<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 section 101, an information reception section 102, an attribute setting section 103, and a transmission section 104. Equipped with

The information search unit 101 searches for information on other servers connected via the network 400 and obtains information on the search results. When various disasters occur, including natural disasters such as meteorological disasters, earthquakes, and eruptions, and man-made disasters such as train accidents and aircraft accidents, for example, new weather disaster information is posted on the Japan Meteorological Agency's website. Sometimes, posted information is obtained as earthquake information, tsunami information, weather information, etc. In addition, when an evacuation preparation order is posted on a local government website, power outage information (information indicating the area of power outage) is posted on an electric power company's website, or railway information is updated on a railway company's website, Obtain published information as evacuation information, lifeline information, and traffic information.

In addition, when damage information such as employee safety confirmation, base damage confirmation, and business partner damage confirmation is posted on a company's homepage, the information search unit 101 posts each information as safety information, base information, and business partner information. Get information.
Note that the safety information, base information, and business partner information may be obtained by answering a questionnaire or receiving an email, or may be obtained by using SNS (Social networking service), which will be described later.

The information search unit 101 is not limited to such disaster information such as earthquake information, and may acquire information other than disaster information through search. The information search unit 101 acquires information that has increased rapidly through trend analysis, for example, on SNS, as information on communication system failures, information on incidents and accidents, and the like. Further, the information search unit 101 acquires, for example, information such as events posted for tourism on the official site of the region and products that are in season, as local information or tourist information.

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

The sensor connected to the information reception unit 102 is a detection device that detects various information from objects and the environment as physical quantities. 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 singly or in combination. As a result, various information such as temperature changes, water volume changes, and the presence or absence of damage or malfunction is acquired regarding the locations and items set as detection targets. The specific configuration of the sensor is specified depending on the target for which information is to be acquired, the type of information to be acquired, the type of event to be detected, and the like.

The camera connected to the information reception unit 102 is an imaging device that acquires images as information. The image acquired by the camera may be either a moving image or a still image, and may be set depending on the object to be photographed or the type of information to be acquired. When acquiring a moving image, in addition to moving image data in a moving image format, a configuration may be adopted in which a set of time-series still image data taken at regular intervals is acquired. Images acquired by the camera are sent to the information providing server 200 as digital data. As the camera, cameras with various configurations may be used depending on the object to be imaged and the usage environment. For example, it may be a fixed camera or a portable camera (handy camera). Furthermore, a wide-angle camera or all-around camera that captures images of a wide surrounding space, a plurality of camera groups that capture images of a specific object or location from various angles, etc. may be used. Furthermore, focusing on the data format of the image to be acquired, it may be a digital camera that acquires the image as a digital image, or an analog camera that acquires the image as an analog image. In the case of an analog camera, an image acquired as an analog image is converted into digital data and output. The specific configuration of the camera is determined depending on the environment and scene in which video is collected, restrictions on usable equipment, etc.

The microphone connected to the information reception unit 102 is a device that records sound as information (acoustic information). As the microphone, microphones having various characteristics and configurations may be used depending on the location to be recorded, the type of acoustic information, etc. For example, when recording a person's voice or the operating sound of a specific object, a highly directional microphone is used that has sound range characteristics that match the range of the voice or operating sound. Furthermore, when recording voices of people gathered in a certain size area or environmental sounds, omnidirectional or low-directional microphones are used. The acoustic information recorded by the microphone is sent to the information providing server 200 as digital data. Furthermore, the microphone itself can have various configurations, such as a fixed microphone, a sound collecting microphone, and a microphone array with strong directivity. The specific configuration of the microphone is determined depending on the environment and scene in which recording is performed, restrictions on 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 reception unit 102. Attribute information, which is information about set attributes, is a plurality of elements used when the user wants to narrow down information, and it is possible to narrow down by combining them.

The attributes set by the attribute setting unit 103 include information indicating the area, information indicating the level, information indicating the type (category), and time of the acquired information as multiple elements. ), and may also include other information other than these pieces of information.
Information indicating a region refers to information for specifying which region the acquired information relates to, and specifies a geographical range (district). The information indicating the degree refers to information for specifying one of a plurality of predetermined stages, and specifies the degree of urgency, severity, importance, etc. (level). The information indicating the type refers to information indicating which predetermined category it belongs to, and the information indicating the time refers to information indicating at what point in time the situation is. Further, other information is allowed to be set according to the acquired information.

For example, when information is obtained that an earthquake has occurred, the information indicating the area includes the location of the epicenter and the area where the seismic intensity was detected, and the information indicating the magnitude indicates the scale of the earthquake. This includes magnitude and intensity, which indicates the magnitude of shaking in each region. The information indicating the type is an earthquake, and the information indicating the time is the time of occurrence of the earthquake. Further, other information includes, for example, that there is a possibility of a tsunami caused by an earthquake.

Attributes are set by analyzing the acquired information and detecting the information source and acquisition status. 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 the railway that operation is suspended on the Yamanote Line, the information indicating the region is "Yamanote Line", and the information indicating the extent is most likely For example, "4" is selected from "1" for the lightest to "5" for the most serious, "Railroad information" is the information indicating the type, and "15:48, September 9, 2021" is the information indicating the time. In this case, other information may be, for example, "injury accident."
The number of other pieces of information is not limited to one, but may be plural. Search accuracy can be improved by specifying more than one. For example, in the above-mentioned example, the other information includes "injury accident", "outside driving", "no prospect of resuming operation", etc. The number of other pieces of information can be changed for each event piece of information.
Note that the acquired information is stored in a storage means such as a nonvolatile memory, and is also stored together with the set attribute information.

Note that although this embodiment employs a configuration in which the information acquisition device 100 includes the attribute setting section 103, the present invention is not limited to this. That is, the information providing server 200 may include the information acquisition device 100 instead of the information acquisition device 100. Further, a configuration may be adopted in which each of the information acquisition device 100 and the information providing server 200 includes the attribute setting unit 103.

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 transmitter 104 transmits the acquired information together with the attribute information to the information providing server 200.
In addition to transmitting to the information providing server 200 when a predetermined time condition is satisfied, the transmitting unit 104 may transmit the information 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 information acquired from the information acquisition device 100 and provides the terminal device 300 (see FIG. 1) with information corresponding to a request from a user among the managed information.
More specifically, information management in the information providing server 200 is performed using attributes of the acquired information. Therefore, the acquired information can be managed and accumulated using multiple attributes.
Further, a request from a user is made, for example, at the terminal device 300, and is made based on an attribute selected from a plurality of attributes. The provided information, which is information provided in response to a user's request, is specified using the attribute selected by the user.
The information here includes event information such as disaster information, and may include information other than event information.

FIG. 3 is a diagram showing the functional configuration of the information providing server 200.
The information providing server 200 includes a transmitting/receiving section 201 , an acquired information analyzing section 202 , an attribute managing section 203 , a provided information specifying section 204 , and a notification content creating section 205 . The transmitting/receiving 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 unit.

The transmitting/receiving unit 201 of the information providing server 200 is a network interface that connects with the information acquisition 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 acquisition device 100 , receives narrowing conditions and the like from the terminal device 300 , and transmits provided information that is the narrowing result 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 transmitting/receiving unit 201, and determines whether there is a relationship with already acquired event information.
Further, 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 there is any missing attribute information or information that can be added to the attribute information of the event information.

When the acquired information analysis unit 202 determines that the received event information is related to already acquired event information, the attribute management unit 203 associates and manages the related event information.
Further, when the acquired information analysis unit 202 determines that there is missing attribute information or additional information that can be added to the event information, the attribute management unit 203 automatically sets the attribute information or sets the manually input content. do. Note that the attribute management unit 203 may modify or change the attributes set on the information acquisition device 100 side.

The provided information specifying unit 204 narrows down event information whose attributes are managed by the attribute managing unit 203 using narrowing conditions, and specifies information to be provided to the terminal device 300. The narrowing down 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 specified by the provided information identification unit 204. The content of the notification may be composed of text information, may include images or videos, may include audio, or may include only audio.

The functional configuration of the information providing server 200 described above includes a CPU (Central Processing Unit) which is an arithmetic unit, a ROM (Read Only Memory) that stores programs executed by the CPU, and a RAM (Random Access Memory).

<Terminal device configuration>
The terminal device 300 is a device that accesses the information providing server 200 and views event information. The terminal device 300 is realized by, for example, a personal computer (PC) connectable to the network 400, a so-called tablet terminal device, a smartphone, or other information terminal device. Although a plurality of terminal devices 300 are connected to the network 400, one terminal device 300 is shown in FIG. 1, and illustration of the other terminal devices 300 is omitted.

FIG. 4 is a diagram illustrating the configuration of the terminal device 300.
The terminal device 300 includes a control section 301 , a transmission/reception section 302 , a display control section 303 , a display section 304 , and an input reception section 305 .
The control unit 301 controls the operation of the entire device, and includes a CPU, ROM, and 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. 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. The input receiving unit 405 receives input operations by the user of the terminal device 300, and includes an operating device such as a keyboard, a mouse, and a touch panel for the user to operate.

<Management and narrowing down of information in the information providing server 200>
FIG. 5 is a diagram illustrating 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 is set that proceeds from top to bottom, conceptually showing the information to be acquired.
FIG. 5(a) shows a scene where the first report of earthquake information is acquired. The first earthquake information report (breaking report) includes information indicating that an earthquake has occurred (earthquake occurrence information), information indicating that the earthquake occurred at "8 o'clock△△ minutes", and the approximate epicenter. Contains information (preliminary or provisional values) on the ground, magnitude, and depth of the epicenter (information on the epicenter seismic intensity).
Such earthquake occurrence information is managed as information indicating the type, and the earthquake occurrence time is managed as information indicating time. Furthermore, the epicenter is information that indicates the region, and the magnitude and depth of the epicenter are managed as information that indicates the extent.

Furthermore, earthquake information usually includes seismic intensity information for various locations around the epicenter, but such seismic intensity information for each location is managed as other information. In other words, the locations where the seismic intensity is indicated are associated with the seismic intensity of each location and managed. The number of other pieces of information is not limited to one, and may be more than one.

Furthermore, seismic intensity information for each location is not limited to being managed as other information. For example, the seismic intensity of each region may be managed as information indicating the region, and the seismic intensity of each region may be managed as information indicating the degree. That is, earthquake information, which is information indicating a type, may be associated with a plurality of pieces of information indicating an area and information indicating a degree.
In this way, for any one of the information indicating the type, information indicating the region, information indicating the degree, and information indicating the time (for example, information indicating the type), information other than the one information (for example, A part or all of the information (information indicating the area, information indicating the degree, and information indicating the time) may be managed so as to be associated with a plurality of pieces.

FIG. 5(b) shows a scene where the second report (detailed report) of earthquake information is acquired and the first report of tsunami information is acquired. When the second report of earthquake information is acquired, it is managed together with the already acquired first report of earthquake information as a type of information called earthquake information.
The time when the second report was announced is "8 o'clock□□ minutes", and this time is managed as information indicating time. Therefore, earthquake information can be illustrated as a cylinder extending in chronological order.

To explain further, the second report includes seismic intensities in a wider range of areas than the first report, and also contains more accurate information on the epicenter and magnitude than the first report. may also include information on the exact epicenter, magnitude and depth. When a second report, which is an updated version of the first report, is acquired, the second report is not managed by overwriting the first report, but the first report and the second report are managed together in a connected manner.

In addition, the tsunami information in Figure 5(b) includes the expected time of arrival at each location and the expected height of the tsunami, as well as the areas in which the warning or advisory will be issued when a tsunami warning or advisory is announced. Contains information indicating which of the following was announced.
More specifically, the first tsunami information report includes information indicating that a tsunami may occur (tsunami possibility information) and the time when the tsunami information was announced as "8:00". Contains information indicating that It also includes information showing the expected arrival time and height of the first wave in each region, as well as information showing announced warnings and advisories.

The tsunami occurrence possibility information here is managed as information indicating the type, and the tsunami information announcement time is managed as information indicating the time. Further, each place is information indicating a region, and information indicating a warning/advisory is managed as information indicating the degree. Furthermore, information indicating the expected arrival time of the first wave in each location and its height is managed as other information.

Here, the information indicating the type of the acquired tsunami information is different from the earthquake information. Therefore, as shown in FIG. 5(b), a tsunami information column is added in addition to the earthquake information column. However, the information indicating the time in the tsunami information is "8 o'clock ○○ minutes" after "8 o'clock △△ minutes", and the columns of the tsunami information are illustrated according to the time axis, similar to the earthquake information.

FIG. 5C shows a scene in which the third report of earthquake information and the second report of tsunami information are acquired, as well as the first report of safety information.
The third earthquake information report was announced at 8:00▽▽ minutes.For example, in the case of an earthquake that shook a wide area, the collection of seismic intensity information in each area could not be completed in time for the second report, or An announcement will be made when the magnitude and depth of the first report are corrected based on subsequent accurate calculations.

Earthquake information is not only divided into first, second, and third reports for a single earthquake, but also when there are aftershocks followed by a main shock and then aftershocks. can also be considered. In addition to managing the main shock and aftershocks in association with each other, it is also possible to manage them independently. In the case of an earthquake swarm where aftershocks occur multiple times a day, independent management may be considered in addition to linked management.

The second tsunami information report was announced at 8:00◎◎ minutes, and in the case of information that there is a possibility of a tsunami occurring, it is a prediction that the first wave will reach a wider area than the first report. Contains time and height information. Furthermore, when the first wave arrives, the second report includes information indicating the place and time of arrival, its height, etc. Depending on the subsequent situation, when further tsunami information is announced after the third report, the information providing server 200 sequentially acquires the information and manages the information.

Safety information is information that confirms whether a company's employees are safe after an earthquake or tsunami occurs, and is automatically obtained based on the results of a questionnaire sent by the company to employees. Alternatively, the information may be obtained by manual input by a user based on an email report from an employee. In addition to being performed on the information providing server 200, such manual input may be configured to be performed on the terminal device 300, or may be configured so as to be performed on the information acquisition device 100. It's okay.

Safety information is shown in a separate column from the earthquake information and tsunami information columns.
The first report of safety information includes information indicating safety confirmation (safety confirmation information) and information indicating that the time when the safety confirmation information was acquired is "8:00 XX minutes." It also includes information indicating the name and result of the safety confirmation. The results of the safety confirmation include whether the person is safe, the presence or absence of injuries, such as minor/serious injuries, and the degree of injury.

The safety confirmation information is managed as information indicating the type, and the acquisition time is managed as information indicating the time. Furthermore, if the name in the safety confirmation includes information indicating the residence area, work area, and whereabouts, that information is managed as information indicating the area. Furthermore, the presence or absence of injuries, which is a result of safety confirmation, is managed as information indicating the degree of injury.

In addition, information indicating the name and result of safety confirmation is managed as other information. In addition, if information that associates a name with an organization affiliation is included, the information indicating the organization affiliation may also be managed as other information. Further, if the safety information includes notification items, the notification items may be managed as other information.

In this way, safety information is managed based on the acquisition time, but unlike the earthquake information and tsunami information mentioned above, it is acquired relatively frequently each time, so safety information in follow-up reports after the second report is determined in advance. Information may be managed in units of time intervals.
If the predetermined time is, for example, 15 minutes, the safety information acquired until 15 minutes have elapsed since the acquisition time of the first report will be treated as the second report, and the safety information will be sent 30 minutes after 15 minutes have passed from the acquisition time of the first report. The safety information obtained before the end of the period is treated as the third report, and the safety information from the second report onward is managed in 15-minute intervals.

It should be noted that the information acquired by the information providing server 200 may be in the form of not only text but also videos (e.g., images from a camera installed on a river), still images (e.g., satellite photos, etc.), and audio. Even in such cases, attributes are assigned and managed using attributes.

FIG. 6 is a flowchart showing an example of a processing procedure of the information providing server 200, in which (a) shows a case in which event information is managed, and (b) shows a case in which event information is narrowed down. Event information is narrowed down based on event attribute information.
In the processing example shown in FIG. 6A, when the transmitter/receiver 201 (see FIG. 3) of the information providing server 200 acquires event information from the information acquisition device 100 (see FIG. 1) (step 101), the acquired information analyzer 202 (see FIG. 3) analyzes the attributes of the event information (step 102). This allows it to be determined whether the acquired event information is related to already acquired event information.

Thereafter, the attribute management unit 203 (see FIG. 3) determines whether there is an addition or change to the attributes of the event information (step 103). If there is an additional change (Yes in step 103), the attribute is additionally changed (step 104) and managed (step 105). If there is no additional change (No in step 103), management is performed using the acquired event information (step 105).
Management here refers to associating already acquired event information with related items based on the attributes of the event information, and is as explained in FIG. 5.

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 narrowing conditions from the terminal device 300 (see FIG. 1) (step 111), the provided information specifying unit 204 (see FIG. (see FIG. 3) narrows down event information based on narrowing conditions (step 112). The narrowing down conditions include area conditions, extent conditions, type conditions, time conditions, and other conditions that correspond to attributes of event information.

As described above, the narrowing down method using narrowing conditions is performed by the provided information specifying unit 204 (see FIG. 3), but to explain it conceptually, cross-sectional information is created according to the time condition among the narrowing conditions, and cross-sectional information is created according to the type condition. The types are narrowed down based on the information, and further narrowed down based on regional conditions, degree conditions, and other conditions. Note that 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 notification content (step 113). The created notification content is output by the transmitting/receiving unit 201 to the terminal device 300 (step 114).

After that, the transmitting/receiving unit 201 determines whether there is an instruction to change the narrowing down conditions from the terminal device 300 (step 115), and if there is a change (Yes in step 115), the process returns to step 112 and the changed narrowing conditions The results will be narrowed down. If there is no change (No in step 115), the process ends.

<Example of management/narrowing down>
FIG. 7 is a conceptual diagram showing an example in which various types of information acquired before and after an earthquake are classified by type. In other words, various types of acquired event information are conceptually represented as a column as a set of information associated with each other by attributes.
In the example shown in FIG. 7, nine columns including the earthquake information column 11 are shown, and illustration of other columns is omitted. That is, a tsunami information column 12 is shown next to an earthquake information column 11, followed by a weather information column 13, an evacuation information column 14, a lifeline information column 15, a traffic information column 16, and a safety information column. 17, a column 18 for base information, and a column 19 for customer information. In this way, acquired information is displayed three-dimensionally for each type.

The arrangement order of the positions of the cylinders 11 to 19 shown in FIG. 7 is defined for each predetermined category, and the arrangement is determined based on information indicating the type. The arrangement is not limited to this, and the user may be able to select the order in which the cylinders are arranged, or the arrangement may be determined in the order in which the first reports are acquired.
The positions of the cylinders 11 to 19 with respect to the time axis are determined based on information indicating time. More specifically, the weather information column 13 and the traffic information column 16 are obtained before the first report of earthquake information, and may be a follow-up report instead of the first report. Moreover, the lifeline information column 15 is the first report of the timing after the occurrence of the earthquake.

Here, in FIG. 7, earthquake information is shown by one column 11, but if multiple earthquakes occur, a column will be shown for each earthquake instead of one. For example, if there is one aftershock after the main shock, the column of the aftershock will be shown separately from the column of the main shock. Additionally, if there were multiple aftershocks, each aftershock is indicated by a cylinder.

In addition, although one weather information column 13 is shown in FIG. 7, since there are multiple pieces of weather information such as heavy rain information and landslide warning information, it may be used together with or in place of the weather information column 13. , a column for heavy rain information or a column for landslide warning information (not shown) may be shown. Furthermore, when heavy rain information and landslide warning information extracted from weather information are displayed separately together with the weather information, the heavy rain information cylinder and the landslide warning information cylinder are arranged in spirals on the circumferential surface of the weather information cylinder 13. It may also be shown as extending in a shape.

When the time axis shown in FIG. 7 is a time axis of hours, minutes and seconds, this is a case where information indicating an ever-changing situation is cut at an arbitrary time to generate cross-sectional information, but the present invention is not limited to this. For example, the time axis may be one week divided by day of the week from Monday to Sunday. In such a case, cross-sectional information can be created for each day of the week.

Moreover, the plurality of columns shown in FIG. 7 may be ones that accumulate information for a plurality of users, but are not limited to this. By managing acquired information for each user, information customized for each user may be managed and cross-sectional information may be formed for each user.

Note that in the example shown in FIG. 7, acquired information is shown in a form divided into columns extending in the time axis direction for each type of information, but the information is not limited to this, and may be shown in a column shape other than a cylinder. good. Furthermore, although the example shown in FIG. 7 shows cylinders having the same shape, the cylinders may have different shapes depending on the type of information. Furthermore, although the example shown in FIG. 7 shows cylinders with the same outer diameter, cylinders with different outer diameters may be used depending on the type of information, or cylinders with different outer diameters may be used depending on the importance of the information. may be shown.

FIG. 8 is a diagram illustrating cross-sectional information of event information, in which (a) shows the time point 60 minutes after the earthquake occurrence, and (b) shows the time point 120 minutes after the earthquake occurrence. The cross-sectional information of event information referred to here refers to the cross-sectional information of event information when various types of acquired event information are conceptually represented as a cylinder as coherent information related by attributes, and when the cylinder is cut at a certain position (time). Information corresponding to a circular cross section.
The cross-sectional information shown in FIG. 8(a) includes a column 11 for earthquake information, a column 12 for tsunami information, a column 13 for weather information, a column 15 for lifeline information, a column 16 for traffic information, a column 17 for safety information, and a column 17 for safety information. Information corresponding to the cross section of the information cylinder 18 is included. The cross-sectional information 60 minutes after the earthquake occurrence does not include information corresponding to the cross-sections of the evacuation information column 14 and the customer information column 19.
Since a summary is created based on such cross-sectional information, evacuation information and customer information will not be displayed in the summary if 60 minutes have passed since the earthquake occurred.

In addition, the cross-sectional information shown in FIG. 8(b) includes a column 11 for earthquake information, a column 12 for tsunami information, a column 14 for evacuation information, a column 15 for lifeline information, a column 16 for traffic information, and a column 17 for safety information. , information corresponding to the cross sections of the base information column 18 and the customer information column 19 is included, while the information corresponding to the weather information column 13 is not included.
In this way, information included in cross-sectional information at a certain point in time may not be included in cross-sectional information at another point in time. In other words, the position on the time axis determines what type of information is included in the cross-sectional information. To explain further, it is determined whether the first report or the second report is included depending on the cutting position on the time axis.

Although FIG. 8 shows a case where a cylinder that is divided by information indicating the type and extends in the direction of the time axis is cut by time, the column is not limited to this, and may be cut by any attribute. That is, the attributes of event information are used not only to classify event information, but also as elements for cutting cross-sections, that is, narrowing down.
Further, in FIG. 8, the classification is by type and time axis, but the invention is not limited to this, and the classification may be made by combining other elements, for example, by region and type.

Further, although FIG. 8 shows cross-sectional information taken at a certain time, the cross-sectional information is not limited to this, and it is also possible to use cross-sectional information as cross-sectional information taken within a certain time range from the beginning to the end. For example, by generating cross-sectional information for each day within a time range of 10 days from the occurrence of an earthquake, it is possible to generate summarized information viewed from a wide field of view.

FIG. 9 is a diagram illustrating a narrowing-down condition input screen displayed on the display unit 304 of the terminal device 300.
The display unit 304 shown in FIG. 9 displays a screen for inputting the narrowing-down conditions accepted by the information providing server 200 in step 111 of FIG. 6(b) described above, and shows inputtable items.

Items that can be input correspond to attributes, such as type, time, region, and degree, and other conditions. An add button 31 is provided for other conditions, and when the add button 31 is pressed, additional items for other conditions are displayed. This allows you to input multiple other conditions.

When the input operation for specifying values for the necessary items is completed, the narrowing down conditions are transmitted to the information providing server 200 by pressing the narrowing down execution button 32. More specifically, the information input in the type item in FIG. 9 is transmitted as the type condition of the narrowing-down condition. Further, the information input in the time item is transmitted as the time condition of the narrowing down condition. Information input into the area and degree items are transmitted as area conditions and degree conditions, respectively, and information input into other condition items is transmitted as other conditions.
The type condition is information indicating the type of a plurality of attributes, and the time condition is information indicating time. Further, the regional condition, degree condition, and other conditions are information indicating the region, information indicating the degree, and other information, respectively.
Note that in the display example shown in FIG. 9, the add button 31 is provided for other conditions, but the add button 31 is not limited to this, and may be provided for other items.

FIG. 10 is a diagram illustrating a narrowing-down result display screen displayed on the display unit 304 of the terminal device 300, in which (a) is one example, and (b) is another example.
In the example shown in FIG. 10A, “60 minutes later/Summary screen 1/n” is displayed on the display unit 304. This shows that this is a summary screen where the time in the narrowing down condition is 60 minutes after the earthquake occurred.
Further, the summary screen has contents spanning n pages (n is a natural number of 2 or more), and the displayed page is the first page.
Note that in order to display the remaining summaries, the next display button 33 is pressed.

As described above, in the example shown in FIG. 10(a), the time condition is narrowed down to 60 minutes after the occurrence of the earthquake.
Further, in one example, all types are displayed on the display unit 304 without being narrowed down based on type conditions. That is, as shown in FIG. 10(a), the first page of the summary displays earthquake information, tsunami information, weather information, and lifeline information. From the second page onwards, traffic information, safety information, base information (see FIG. 8(a)), etc. are displayed.
Furthermore, in one example, the search results are narrowed down based on one or more combinations of area conditions, degree conditions, and other conditions.
In one example, when the search is narrowed down based on at least a time condition and a region condition, one of the time condition and the region condition is an example of the first attribute, and the other is an example of the second attribute.

In addition, if the narrowing down conditions are changed and the narrowing down is performed again, the change narrowing condition button 34 is pressed (see Yes in step 115 in FIG. 6(b)). That is, by changing the values specified in the items on the narrowing-down condition input screen (see FIG. 9), narrowing down of different contents can be executed.

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 clearly indicated what information among the information indicating the type is not included in the cross-sectional information.

In another example shown in FIG. 10(b), a “60 minutes later summary screen” is displayed on the display unit 304 of the terminal device 300. The other example in Figure (b) is similar to the example in Figure (a) in that it is a summary screen after 60 minutes, but it is different from the example in which it has n pages in that the summary is one page. do.
More specifically, in another example, earthquake information is input in the type item of the narrowing-down condition input screen (see FIG. 9), and the type condition is earthquake information. Moreover, the time condition is 60 minutes after the occurrence of the earthquake. Therefore, of the cross-sectional information after 60 minutes (see FIG. 8(a)), only the earthquake information is included in the summary. In another example, one of the type condition and the time condition is an example of the first attribute, and the other is an example of the second attribute.
Note that in other examples as well, if the narrowing down conditions are changed and the narrowing down is to be performed again, the change narrowing condition button 34 is pressed.

As described above, in this embodiment, the information providing server 200 acquires event information from the information acquisition device 100 (see FIG. 1), manages/narrows down the acquired event information based on attributes, and converts the narrowing results into summarized information. Alternatively, a configuration is adopted in which the user is notified from the terminal device 300 as the cross-sectional information. This makes it possible to ensure accuracy in narrowing down the conditions requested by the user regarding event information that may have different update times and frequencies. Furthermore, it becomes possible to provide summarized information on an individual basis.

Note that the narrowing-down result display screens shown in FIGS. 10(a) and 10(b) are displayed on the display unit 304 under the display control of the display control unit 303 (see FIG. 4) in the terminal device 300 that received the notification content. Yes, it is composed of characters. However, it 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 cross-sectional information and the mouse-over is performed, the corresponding narrowing-down results 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, SNS, by narrowing down by attributes at an arbitrary timing to generate cross-sectional information, it is possible to generate an arbitrary trend situation.

In addition, if the acquired information is tourist information and cross-sectional information is generated by narrowing down by attributes at an arbitrary timing, 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 events, and cross-sectional information is generated by narrowing down by attributes at any timing, it can be generated as arbitrary event information, and can be used for online applications for travel products, etc. Can be used in combination.

Furthermore, if the obtained information is restaurant information and cross-sectional information is generated by narrowing down the information by attributes at any timing, it can be generated as arbitrary gourmet information, and can be used in combination with navigation apps, etc. can.
Furthermore, if the acquired information is news information and cross-sectional information is generated by narrowing down based on attributes at an arbitrary timing, it can be generated as any online newspaper media. Further, even for individual users, it is possible to provide summarized information on news from a particular field of interest, such as politics or sports, as of a certain point in time, for example, at 1:00 p.m.

In addition, if the acquired information is sensor data, etc., and cross-sectional information is generated by narrowing down by attributes at any timing, it can be generated as a regular arbitrary measurement table, and digital data that reproduces real space in virtual space can be used. It can be generated as a database to realize twins.

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

Note that the acquired information may be sensor information or unique data owned by the user, in which case, for example, the acquired information acquired from the terminal device 300 may be linked with the acquired information acquired from the information acquisition device 100. You can also manage it. For example, the information providing server 200 acquires sensor information indicating whether a factory's equipment system is operating or not and combines it with other information to confirm that the factory's equipment system was still operating even after an earthquake occurred. You can check it.

FIG. 11 is a diagram illustrating a narrowing-down result display screen displayed on the display unit 304 of the terminal device 300.
In the display screen shown in the figure, a “summary screen” and a “time series display” are displayed on the display section 304. A time series table 35 having vertical and horizontal directions is displayed on the display unit 304.

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

In the vertical direction of the time series table 35, summaries of the narrowing down results are arranged in chronological order. The chronological order here means that the summaries are arranged in the order of the time when the narrowing down was performed using the narrowing conditions, and it is also possible to select either ascending order (oldest first) or descending order (newest first).

In this way, the display section 304 shown in FIG. 11 is in a table format in which the horizontal direction shows the narrowing down conditions and cross-sectional information based on the narrowing down, and the vertical axis is the time axis.
More specifically, the output format in FIG. 11 is different from that in FIG. 10. That is, the display section 304 in FIG. 10 displays only the most recent summary that has been narrowed down using the narrowing down conditions, and the displayed content is replaced when the next narrowing down is performed. That is, the summaries for one narrowing down are sequentially switched and displayed, thereby being updated.
On the other hand, in the display section 304 of FIG. 11, past narrowing down results are displayed in chronological order, and when the next narrowing down is performed, information is provided in a format with the narrowing down results added. In other words, the display unit 304 in FIG. 11 shows a summary in a table format as a log of the narrowing down results. Therefore, it is possible to check the summary of what happened when and where across multiple narrowing results.

As shown in FIG. 11, a save button 36 is displayed on the display unit 304, and the user can save the data of the time series table 35 by pressing the save button 36 as necessary. Note that automatic saving may be performed at fixed time intervals, or automatic saving may be performed at the timing when a narrowing-down result is added.

Note that data extraction may be performed by specifying conditions on the display unit 304 shown in FIG. 11. For example, data is extracted by combining earthquake information and the Chugoku region, and only a summary of the extracted data is displayed on the display unit 304 in chronological order. Furthermore, by extracting data by combining earthquake information and Hokkaido, different summaries are displayed in chronological order on the display unit 304.

Furthermore, in the display section 304 shown in FIG. 11, items to be displayed may be selected, the selected items may be displayed, and the unselected items may not be displayed. Alternatively, it may be possible to perform a text search for summaries, and to display narrowed-down results including summary items found in the text search results in chronological order.

In this way, the narrowed-down results are summarized so that you can see the whole thing at a glance, making it easy to access the information you need. Furthermore, since it is in a table format, desired information can be quickly accessed by searching for characters 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.
The display screen shown in FIG. 12 displays cross-sectional information obtained by narrowing down event information in a manner different from that shown in FIG. be. This notifies you of how the narrowed-down event information changes over time.

More specifically, the comparison result display screen 37 narrows down event information using a combination of time conditions and one or more conditions other than time conditions, such as type conditions, region conditions, degree conditions, or other conditions. The results of comparison of cross-sectional information are shown below. The results here are, for example, a comparison between FIGS. 8(a) and 8(b) described above.
One of the time condition and a condition other than the time condition is an example of the first attribute, and the other is an example of the second attribute. “60 minutes after the earthquake occurs” in FIG. 8A is an example of the first time information, and the cross-sectional information is an example of specific use of the first time information. ``120 minutes after the earthquake occurrence'' in FIG. 4B is an example of the second time information, and the cross-sectional information is a specific example of using the second time information.

In the area 41, for each item "Response rate", "Not responded to", "Injury etc.", and "Safe", in addition to numerical display, an arrow mark 47 which is information indicating changes over time is displayed. There is. The arrow mark 47 is a symbol representing one direction, and the user can be notified of a change depending on the direction of the arrow.
As for the state of change here, an upward arrow indicates an "increase" change, a downward arrow indicates a "decrease" change, and a rightward arrow indicates "no change."

Note that instead of the arrow mark 47 shown in the area 41, another type of arrow mark, a hand mark with the index finger extended and the other fingers bent, or a triangle mark may be used to indicate upward, downward, or rightward. good. Further, the orientation may be shown as diagonally upward, diagonally downward, or rightward.
Further, the arrow mark 47 may be displayed in different colors depending on the direction in which it is pointed. Further, the magnitude of the change may be displayed in a display manner using the size of the arrow mark 47, the thickness of the line, the color, etc.

The area 42 indicating "base influence" shows the start time and elapsed time as in the case of the above-mentioned area 41, and also indicates "impacted (small scale)" as the "base influence" for status confirmation. In addition, in area 42, status confirmation is divided into the following categories: ``Impacted (large scale)'', ``Impacted (medium scale)'', ``Impacted (small scale)'', and ``Confirmed'', and 0 is set for each item. Indicates the number of cases included. Further, a summary of items having one or more items may be displayed.
Note that although the graph display section 41b of the area 41 is not displayed in the area 42, it may be displayed. Further, although the arrow mark of the area 41 is not displayed in the area 42, it may be displayed.

In the area 43 indicating "task", the start time and elapsed time are shown as in the case of the area 41 described above, and the "response status" of the task is shown as a percentage. Further, regarding the issues, the area 43 is divided into the following items: ``Not handled'', ``Working'', and ``Completed'', and a numerical display section 43a is displayed for each item, indicating the number of applicable items and the ratio thereof to the whole. . Further, in the area 43, a graph display section 43b is displayed for the task, and an arrow mark 47 is also displayed.

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

These areas 44 to 46 are divided into "occurrence/continuation" and "recovery/cancellation" items, and indicate the number of cases for each item. Further, areas 44 and 45 show the corresponding event information and the number of "occurrence/continuation" and "recovery/cancellation" for each event information. Further, in the area 46, the site incident status is divided into specific items, and the number of cases of "occurrence/continuation" and "recovery/cancellation" is shown for each item.
Furthermore, arrow marks 47 indicating changes over time are displayed in the areas 44 to 46.
