The record

Purpose: The Python Record Linkage Toolkit is a Python library for linking records between data sources and finding duplicates within a source.
Intended use: The project is developed for research and linking small or medium sized files.
Data preparation: It provides tools to clean and standardize data, including phonetic encoding.
Candidate generation: Its indexing methods include blocking and sorted neighbourhood indexing to make candidate record pairs.
Record comparison: It compares strings, numbers, and dates using comparison and similarity measures.
Classification: It includes supervised and unsupervised classification algorithms.
Evaluation: The toolkit includes record linkage evaluation tools and built-in datasets.
Extensibility: Users can add their own indexing algorithms, comparison or similarity measures, and classifiers.
Integrations: The toolkit uses pandas and NumPy, and its pandas integration can fit into existing data manipulation projects.
Install: The package can be installed with pip or cloned from GitHub; the stable installation page says it requires Python 3.6 or higher.
Scale limit: The project describes its intended workload as small or medium sized files; full indexing can be slow on large dataframes because comparisons scale quadratically.
License: The project repository identifies the toolkit's license as BSD-3-Clause.
Support: The project repository directs users with questions to contact the maintainer by email.
