In this paper, the authors detail about various methods prevailing in literature for efficient discovery of matching dependencies. The concept of Matching Dependencies (MDs) has recently been proposed for specifying matching rules for object identification. Similar to the functional dependencies with conditions, MDs can also be applied to various data quality applications such as detecting the violations of integrity constraints. The problem of discovering similarity constraints for matching dependencies from a given database instance is taken into consideration.
