Dedupe Python Library
dedupe is a python library that uses machine learning to perform fuzzy matching, deduplication and entity resolution quickly on structured data.
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.

Tools built with dedupe
A full service web service powered by dedupe for de-duplicating and find matches in your messy data. It provides an easy-to-use interface and provides cluster review and automation, as well as advanced record linkage, continuous matching and API integrations. See the product page and the launch blog post.
If you only want to use dedupe, install it this way:
pip install "numpy>=1.9" pip install dedupe
Once you have virtualenvwrapper set up,
mkvirtualenv dedupe git clone git://github.com/datamade/dedupe.git cd dedupe pip install "numpy>=1.9" pip install -r requirements.txt cython src/*.pyx pip install -e .
If these tests pass, then everything should have been installed correctly!
