DataGroomr allows users to create matching rules powered by machine learning that determine how duplicates are identified.  Unlike out-of-the-box rules that are based on Datagroomr's experience with many customers, these are limited to the fields that are determined by you and trained exclusively on your data.   

To accomplish this we provide a Matching Rules feature in the Supervisor module that allows you to specify fields (and matching criteria) that is most appropriate for your needs.
