FIELD: information technology. ^ SUBSTANCE: query is sent to a database with an interface attribute set to the value of the global attribute. The number of times the global attribute value occurs as the value of the resultant attribute of the query result for each combination of the global attribute of the global domain scheme, the interface attribute of the interface scheme and the resultant attribute of the resultant database scheme is counted. Mutual information between pairs of schemes based on the counting values is assessed. Based on the assessment of the mutual information, attributes which correspond to each other are identified. Indicators of corresponding attributes are stored. ^ EFFECT: invention enables identification of attributes of different schemes, which semantically offer the same content. ^ 15 cl, 13 dwg, 5 tbl |
