Patent ID: 8271511

Claim:
A computer-implemented method for forming a mark reference list using an automated information retrieval system with database including a register of mark-forming objects in the form of a sample array, and a mark array, wherein a query sample is compared to a mark of the mark array, and a match index between the query sample and the mark is determined based on said comparison, and the decision is made whether the mark should be included into the mark reference list based on said index, characterized in that the mark is compared with each sample of the sample array, match indexes between the mark and said each sample are determined based on said comparison, and a list of high match indexes of the mark and the samples is formed, and the decision is made that the mark should be included into the mark reference list if said match index between the query sample and the mark is higher than the lowest match index from said list of high match indexes of the mark and the samples.
