Abstract

The present invention extends to methods, systems, and computer program products for selecting candidate records for deduplication from a table. A table can be processed to compute an inverse index for each field of the table. A deduplication algorithm can traverse the inverse indices in accordance with a flexible user-defined policy to identify candidate records for deduplication. Both exact matches and approximate matches can be found.
