Information display system and information display method
A crime prediction server accesses an SNS server, collects submission information, which includes crime-related terms, as crime-related information from the submission information of general citizens, calculates statistical data for each attribute, which includes an occurrence place, a crime occurrence hour, a crime type of a crime, for the crime-related information, and sends crime data and map data, which are extracted from the statistical data of the crime-related information, in response to a request from a center device. The center device superimposes the crime data on the map data for each attribute on a display, and plots and displays the crime data in a position corresponding to the crime occurrence place on a map.
1. A system for assisting law enforcement in predicting future incidents of crime to which a server device that collects crime-related information relevant to an incident, a client device that includes a display for displaying the crime-related information, and a disposition server are coupled,
wherein the server device
determines a position of a site terminal of the law enforcement;
accesses, based on the position of the site terminal, a Social Networking Service (SNS) server that accumulates SNS submission information of persons, collects SNS submission information, which includes crime-related terms, from the SNS submission information as the crime-related information, and records the SNS submission information in a storage, accessing the SNS server including: searching the SNS submission information of the SNS server for at least a plurality of crime types and a plurality of crime tools,
calculates, for the crime-related information, statistical data for a set of attributes for predicting the future incidents of the crime, the set of attributes including a crime occurrence place, an occurrence hour, and a crime type of the plurality of crime types of the crime having the future incidents to be predicted, and
sends crime data for a selected time of day and map data, which are extracted from the statistical data of the crime-related information for the selected time of day, to the client device in response to a request from the client device for the selected time of day, and
wherein the client device
receives the crime data for the selected time of day and the map data which are sent from the server device, and
superimposes the crime data for the selected time of day on the map data for each attribute of the set of attributes on the display, and plots and displays the crime data for the selected time of day in a position corresponding to the crime occurrence place on a map, and
wherein the disposition server
dynamically determines a disposition plan for the law enforcement based on the crime data for the selected time of day, a selection of the crime type of the crime having the future incidents to be predicted, a work schedule of the law enforcement and the position of the site terminal of the law enforcement.
2. The system of claim 1 ,
wherein the client device displays the crime data for the selected time of day, which is narrowed down to a designated attribute, according to an attribute designation input by a user in a case where the crime data for the selected time of day is displayed.
3. The system of claim 1 ,
wherein the client device sends a statistical display request to the server device in a case where a statistical display instruction is given by a user,
wherein the server device sends statistical display data of the crime data for the selected time of day in a display mode in response to the statistical display request to the client device, and
wherein the client device displays statistical information including a statistical graph of the crime data for the selected time of day based on the received statistical display data on the display.
4. The system of claim 3 , wherein the statistical graph is a pie chart showing a distribution of the crime type.
5. The system of claim 3 , wherein the client device:
displays the crime data for the selected time of day on the map data together with a time designation bar usable by a user to select the time of day.
6. The system of claim 1 , wherein the disposition server determines the disposition plan for the law enforcement by scheduling a patrol for the law enforcement.
7. The system of claim 6 , wherein the disposition server determines the disposition plan for the law enforcement by dispatching the law enforcement.
8. A method in a system for assisting law enforcement in predicting future incidents of crime to which a server device that collects crime-related information relevant to an incident, a client device that includes a display for displaying the crime-related information, and a disposition server are coupled, the method comprising:
causing the server device to:
determine a position of a site terminal of the law enforcement;
access, based on the position of the site terminal, a Social Networking Service (SNS) server that accumulates SNS submission information of persons, to collect SNS submission information, which includes crime-related terms, from the SNS submission information as the crime-related information, and to record the SNS submission information in a storage, accessing the SNS server including: searching the SNS submission information of the SNS server for at least a plurality of crime types and a plurality of crime tools,
calculate, for the crime-related information, statistical data for a set of attributes for predicting the future incidents of the crime, the set of attributes including a crime occurrence place, an occurrence hour, and a crime type of the plurality of crime types of the crime having the future incidents to be predicted, and
send crime data for a selected time of day and map data, which are extracted from the statistical data of the crime-related information, to the client device in response to a request from the client device;
causing the client device to:
receive the crime data for the selected time of day and the map data which are sent from the server device, and
superimpose the crime data for the selected time of day on the map data for each attribute of the set of attributes on the display, and to plot and display the crime data for the selected time of day in a position corresponding to the crime occurrence place on a map; and
causing the disposition server to:
dynamically determine a disposition plan for the law enforcement based on the crime data for the selected time of day and a selection of the crime type of the crime having the future incidents to be predicted, a work schedule of the law enforcement and the position of the site terminal of the law enforcement.
9. The method of claim 8 , wherein the client device:
displays the crime data for the selected time of day on the map data together with a time designation bar usable by a user to select the time of day.
10. The method of claim 8 , wherein causing the disposition server to determine the disposition plan includes causing the disposition server to schedule a patrol for the law enforcement.
11. The method of claim 10 , wherein causing the disposition server to determine the disposition plan includes causing the disposition server to dispatch the law enforcement.
