1. A method for implementing a property comparison between several comparison targets with a comparator residing in a server in a data transfer network, which comparator uses at least a two dimensional graphic evaluation frame, the method comprising giving at least one reference evaluation of the properties of a one comparison target by the graphic evaluation frame of a reference user's data processing device and storing the evaluations given as reference in a database of the server implementing the functions of the comparator normalizing evaluations describing the degree of importance of the properties of one comparison target included in the reference evaluations with the graphic evaluation frame of the server, so that an average of the importance evaluations of all the properties is at the origin at the center of the used graphic evaluation frame and the standard deviation of the importance evaluations has a predetermined magnitude giving an evaluation of an evaluated property of one comparison target utilizing the two dimensional graphic evaluation frame of a user's data processing device, which is connected to the data transfer network, and the evaluation is stored in the server determining an accuracy percentage describing the congruency of the evaluations given by the comparator user's data processing device and reference evaluations concerning the same comparison target in the server implementing the comparator presenting on the comparator user's data processing device a total accuracy percentage for all the properties obtained from the congruency comparison created in the server, correcting the accuracy percentage of at least one property of the comparison target in the server with a weighting coefficient determined at least from the reference evaluations and presenting the comparison targets of the comparator in an order determined by a total accuracy percentage corrected with the weighting coefficient on the comparator user's data processing device.
