Dedupe 3.0.2

dedupe is a library that uses machine learning to perform de-duplication and entity resolution quickly on structured data.

If you’re looking for the documentation for the Dedupe.io Web API, you can find that here: https://apidocs.dedupe.io/

dedupe will help you:

• remove duplicate entries from a spreadsheet of names and addresses

• link a list with customer information to another with order history, even without unique customer id’s

• take a database of campaign contributions and figure out which ones were made by the same person, even if the names were entered slightly differently for each record

dedupe takes in human training data and comes up with the best rules for your dataset to quickly and automatically find similar records, even with very large databases.
