Abstract:
1. A symbol analyzing device for analyzing a symbol used in a plurality of communications, comprising: symbol acquiring device configured to acquire, for each of the plurality of communications, one or more symbols used in the communication; first symbol position coordinates calculating device configured to calculate position coordinates of each symbol acquired for each of the plurality of communications by the symbol acquiring device, in a first space having coordinate axes each corresponding to each of the plurality of communications; characteristic direction calculating device configured to calculate one or more characteristic directions in the first space based on the position coordinates calculated by the first symbol position coordinates calculating device; and second symbol position coordinates calculating device configured to calculate position coordinates of each symbol acquired by the symbol acquiring device, in a second space having coordinate axes each corresponding to each of the characteristic directions calculated by the characteristic direction calculating device, based on the characteristic directions calculated by the characteristic direction calculating device and the position coordinates calculated by the first symbol position coordinates calculating device, wherein the first symbol position coordinates calculating device calculates, with respect to each symbol, position coordinates which include, as coordinate components thereof, values calculated depending on use of the symbol in each communication, and wherein the second symbol position coordinates calculating device calculates position coordinates in the second space, of each symbol acquired by the symbol acquiring device, based on an inner product of the characteristic direction calculated by the characteristic direction calculating device and the position coordinates calculated by the first symbol position coordinates calculating device.
