You can use the tMatchGroup component to detect duplicates and define how to merge similar records to create a master record.
Creating a master record is an iterative process: each new master record can be used to find new duplicates.
You can choose between two different algorithms to create master records:
Simple VSR Matcher
The main difference between the two algorithms is that T-Swoosh creates, for each master record, a new record that does not exist in the list of input records.
