Regional attribute determination method, regional attribute determination device, and regional attribute determination program
In a regional attribute determination method for determining a regional attribute representing an attribute of people gathering in each region, user information including the locations and attributes of a number of users is acquired from a number of portable information terminal devices used by the number of users, the acquired user information of the number of users is stored in a user information storage part, and the regional attribute is determined on the basis of the user information of the number of users stored in the user information storage part.
1. A regional attribute determination system for determining a regional attribute representing an attribute of people gathering in a particular region, the system comprising:
an input device;
a display device;
a processor;
a memory device which stores a plurality of instructions, which when executed by the processor, cause the processor to operate with the display device and the input device to:
(a) acquire first user information including a first location and a first attribute of a first user from a first portable information terminal device used by the first user;
(b) acquire second user information including a second location and a second attribute of a second user from a second portable information terminal device used by the second user;
(c) store: the first user information of the first user; and (ii) the second user information of the second user, wherein: (i) the stored first user information is updated in real time every time the first user performs information retrieval; and (ii) the stored second user information is updated in real time every time the second user performs information retrieval;
(d) calculate a first effect on a region by multiplying a first power of influence, the first power of influence being based on said first attribute, wherein said first effect is:
(i) produced by said first user;
(ii) calculated using a regional attribute defining function;
(iii) reduced as said first user moves away from said region; and
(e) calculate a second effect on the region by multiplying a second power of influence, the second power of influence being based on said second attribute, wherein said second effect is:
(i) produced by said second user;
(ii) calculated using a regional attribute defining function;
(iii) reduced as said second user moves away from said region; and
(f) determine the regional attribute by combining: (i) the first calculated effect on each region produced by the first user; and (ii) the second calculated effect on each region produced by the second user.
2. A machine readable media storing a regional attribute determination program for determining a regional attribute representing an attribute of people gathering in a particular region, the program structured to cause a computer to:
acquire first user information including a first location and a first attribute of a first user from a first portable information terminal device used by the first user;
acquire second user information including a second location and a second attribute of a second user from a second portable information terminal device used by the second user;
store: (i) the acquired first user information of the first user; and (ii) the acquired second user information of the second user, wherein: (i) the stored first user information is updated in real time every time the first user performs information retrieval; and (ii) the stored second user information is updated in real time every time the second user performs information retrieval;
calculate a first effect on a region by multiplying a first power of influence, the first power of influence being based on said first attribute, wherein said first effect is:
(i) produced by said first user;
(ii) calculated using a regional attribute defining function;
(iii) reduced as said first user moves away from said region; and
calculate a second effect on the region by multiplying a second power of influence, the second power of influence being based on said second attribute, wherein said second effect is:
(i) produced by said second user;
(ii) calculated using a regional attribute defining function;
(iii) reduced as said second user moves away from said region; and
determine the regional attribute by combining: (i) the first calculated effect on each region produced by the first user; and (ii) the second calculated effect on each region produced by the second user.
