Establishing similarity between objects, e.g. goods - determining similarity of first object to several second objects, determining ranking sequence of second objects and then the quality of goods

摘要

First, data describing parameter model of first object is first determined. The first data is compared with second data of the second parameter model of the second object. The similarity of the two objects is established so that by comparison of two sets of data at least a part of parameters of the first and/or second parameter model is weighed. First, the similarity of the first objects to several second objects is determined then, based on this, the ranking sequence of the second objects is established. The quality of goods is affected based on the ranking sequence. The process can be used to determine the fit comparison between the first and at least one second object.
