# Data Matching software

- [Outdated](#outdated-no-longer-available)
- [Contributing](#contributing)
This is a list of (Fuzzy) Data Matching software. The software in this list is
FOSS (Free and open-source software).
The term data matching is used to indicate the procedure of bringing together
information from two or more records that are believed to belong to the same
entity. Data matching has two applications: (1) to match data across multiple
datasets (linkage) and (2) to match data within a dataset (deduplication).
See the [Wikipedia page](https://en.wikipedia.org/wiki/Record_linkage) about
data matching for more information.
*Similar terms:* record linkage, data matching, deduplication, fuzzy matching,
entity resolution

## Software
This section describes **data matching** software. The software is
alphabetically ordered.
#### [AtyImo](https://github.com/pierrepita/atyimo)
AtyImo implements a mixture of deterministic and probabilistic routines for data
linkage. Initially developed in 2013 to serve as a linkage tool supporting a joint
Brazil–U.K. project aiming at building a large population-based cohort with data
from more than 100 million participants and producing disease-specific data to facilitate
diverse epidemiological research studies.

#### [Dedupe](https://github.com/dedupeio/dedupe)
Dedupe is a python library for fuzzy matching, deduplication and entity
resolution on structured data. The library makes use of active learning to
match record pairs. Active learning is useful in cases without training data.
Dedupe has a side-product for deduplicating CSV files,
[csvdedupe](https://github.com/dedupeio/csvdedupe), through the command line.
Dedupeio also offers commercial products for data matching.

#### [dirty-cat](https://github.com/dirty-cat/dirty_cat)
[dirty-cat](https://dirty-cat.github.io/) is an open-source Python package that facilitates machine-learning with with dirty data: robust to morphological variants, such as typos. Some of the currently supported features are: fuzzy joining tables on dirty numerical, string or mixed type columns, deduplicating and encoding dirty categorical variables for ML. [This example](https://dirty-cat.github.io/stable/auto_examples/01_dirty_categories.html) illustrates why to use dirty-cat encoders rather than OneHotEncoder on dirty data and [this one](https://dirty-cat.github.io/stable/auto_examples/04_fuzzy_joining_and_FeatureAugmenter.html) shows how to join multiple dirty tables for ML.
The transfomers ([TableVectorizer](https://dirty-cat.github.io/stable/generated/dirty_cat.TableVectorizer.html), [FeatureAugmenter](https://dirty-cat.github.io/stable/generated/dirty_cat.FeatureAugmenter.html)) are scikit-learn compatible, and easily introduced into ML pipelines.
