Table classification device, table classification method, and table classification program

Abstract:

The present invention aims to facilitate integration of databases by classifying a plurality of tables in databases into a group of similar tables. A table classification device 1 includes a semantic classifying unit 20 carrying out classification with considering meanings of columns which form a database and a statistical classifying unit 30 carrying out classification based on statistical information of the columns. The tables are classified hierarchically by combining a classification method of the semantic classifying unit 20 and a classification method of the statistical classifying unit 30.
