Latest Patents

David Greenfield holds a patent for a method designed to identify the semantic type of data contained in a column of a table. This innovation introduces techniques for determining the semantic type based on unique 'fingerprints' created from the values within the target column. Notably, the fingerprint set is generated only once, minimizing resource usage by requiring the target column to be scanned just a single time. Once established, this fingerprint set is compared against those corresponding to each semantic type, leading to the generation of a “similarity measure.” The semantic type that achieves the highest similarity measure relative to the target column’s fingerprint set is ultimately identified as the semantic type of the column.
