Jämförelsemetod och -maskin för grafisk jämförelse av målgrupper

摘要

A method, a data network arrangement and a computer program product by which a comparator can be implemented in a data network. The user of the comparator stores his evaluation of the properties included in the targets to be evaluated in a database in the server in the data network using a graphic one- or two-dimensional evaluation frame. In the comparator the comparator user's evaluations are compared to property evaluations given by a reference user. When calculating the total accuracy percentage of the comparison the evaluations given by the comparator user are weighted with a weighting coefficient, which is obtained by normalising first the importance evaluations of all the properties given by the reference user and by using the normalised importance evaluation of a certain property as the weighting coefficient for this property.
