Neer Match Utilities

neermatch is a framework for entity matching that supports deep learning, symbolic learning, and hybrid approaches, using neural networks, gradient boosting, logit, or probit as classifiers. It is tailored to the needs of economic historians and quantitative economists, but generalizes to any domain requiring entity matching.

The neermatch framework encompasses three packages:

1. py-neer-match: The Python implementation of the basic functionalities (ANNs only). Learn more
2. py-neer-utilities: A Python package that provides additional models and functionalities to streamline and support the entity matching workflow. (this project)
3. r-neer-match: The R implementation of the basic functionalites. Learn more

The project is financially supported by the Deutsche Forschungsgemeinschaft (DFG) under Grant 539465691 as part of the Infrastructure Priority Programme New Data Spaces for the Social Sciences (SPP 2431). Reading the article Karapanagiotis and Liebald (2023) helps to understand the theoretical foundation and design of neermatch (note that the article refers to an earlier version of the framework, previously labeled as mlmatch).

The documentation provides examples of how neermatch may be used. The data used in these examples are available in this folder of the GitHub repository.
