<p>PROBLEM TO BE SOLVED: To provide a data exchange support method and apparatus in which data can be exchanged equivalently even between a low subject and a high subject in a value of possessed data.SOLUTION: Two subjects N4, N5 of a value "2" are considered to be candidates of a data exchange pair, and the permission of data exchange is queried [Fig. 5(a)]. When the permission of the data exchange is obtained, the subjects N4, N5 are considered to be the data exchange pair and free data exchange becomes possible [Fig. 5(b)], and a shared subject M45 of a value "4" is born. The value "4" of the possessed data of the shared subject N45 becomes substantially equivalent to a value "3" of the possessed data of a subject N3, so that both are considered to be the candidates of the data exchange pair and the permission of the data exchange is queried. When the permission of the data exchange is obtained, the subjects N3, M45 are considered to be the data exchange pair and free data exchange becomes possible, and a shared subject M345 of a value "7" is born. Similar processing is repeated in the following, and subjects N1, M2345 are considered to be the data exchange pair and free data exchange becomes possible [Fig. 5(d)].</p> |
