World Intellectual Property Organization. 2014. No. Publication Number WO/2014/148948, International Application Number PCT/RU2013/001180.

The invention relates to a method for selecting and ranking valid variants in search and recommendation systems. The claimed method makes it possible to select and rank variants with a high degree of accuracy and speed, especially in the case of a large number of variants which can be characterized by a large set of indicators. In the claimed method (variant), criteria for evaluating the relevance of a variant to the search request are first generated and a set of procedures for the selection and ranking of variants and a sequence for performing said procedures for the selection of variants evaluated as the most valid are established, and an evaluation of each of the variants is made on the basis of the relevance to search request criteria and, on the basis of this evaluation, the variants are ranked by means of assigning a rank to each of said variants based on the condition of correspondence to the greatest number of criteria in decreasing order, and then the variants are selected and ranked in at least two stages using the superposition method, and the variants are selected, ranked and excluded until all of the established selection procedures have been used and the selected group of variants is evaluated as being the most valid.
