Duplicate Detection

Duplicate detection is the process of identifying records, entries, or pieces of information that are the same or very similar within a dataset. It helps prevent redundancy, reduce errors, and improve data quality. For example, in customer databases, duplicate detection ensures that the same person isn't counted twice due to slight differences in name or contact details. This process uses algorithms to compare information and flag potential duplicates so they can be reviewed and consolidated, enhancing the accuracy and usefulness of the data for analysis, decision-making, or operational efficiency.
