About Dedupe
Dedupe is an open-source Python library that uses machine learning for fuzzy matching, deduplication and entity resolution on structured data. It takes human-provided training data and derives rules to find similar records in a dataset.
It can remove duplicate names and addresses, link separate lists such as customer information and order history without shared IDs, and group records where names were entered slightly differently. It is installed with pip install dedupe and used through its Python API.
Key features
- Fuzzy matching of structured records using machine learning
- Deduplication of duplicate names and addresses
- Record linkage across lists without unique IDs
- Learns matching rules from human-provided training data
- csvdedupe command-line tool for CSV deduplication and linking
- Installable with pip install dedupe
Best for: Python developers and data workers who need to deduplicate structured records and link datasets without shared identifiers.
Good for
- Released as open source under the MIT License
- Learns dataset-specific matching rules from human training examples
- Provides example projects and a CSV command-line tool
Watch out for
- Requires Python to install and use the library
- Needs human-provided training data to learn matching rules
