SEARCH TABLES UNDERSTANDING Russian patent published in 2018 - IPC G06F17/30 G06F7/02 

FIELD: computer equipment.

SUBSTANCE: invention relates to computer engineering. Technical result is achieved by selecting a predetermined number of columns from the table as subject candidate columns, each candidate column is potentially suitable for the correct subject table column, with each subject candidate column including a plurality of values; for each subject candidate column: determining the joint occurrence for values in the subject candidate column, including determining how often the values in the subject candidate column also occur in the correct subject columns in a variety of other tables, calculating an estimate for the subject candidate column based on the said determined collaborative occurrence, the computed estimate showing the likelihood that the subject candidate column is the correct subject column; and classifying the subject candidate column as one of the correct subject table column and a non-proprietary column of the table based on the calculated score for the subject candidate column.

EFFECT: technical result consists in increasing the efficiency of detecting one or more subject table columns.
