Abstract
Techniques are provided for determining the semantic-type of a target column based on 'fingerprints' that are created based on the values in the target column. The fingerprint set for the target column is only generated once, not once per semantic-type. Thus, the target column only needs to be scanned once, and resource usage is minimized. Once generated, the fingerprint set of the column is compared against fingerprint set that corresponds to each semantic-type to generate a “similarity measure”. The semantic-type whose fingerprint set produces the highest similarity measure relative to the target column's fingerprint set is determined to be the semantic-type of the target column.
