The Fellegi and Sunter method is a probabilistic approach to solve record linkage problem based on decision model. Records in data sources are assumed to represent observations of entities taken from a particular population (individuals, companies, enterprises, farms, geographic region, families, households.).

The team therefore set about developing a record linking package called Splink. 4. Introducing Splink Splink is a PySpark package that implements the Fellegi-Sunter model of record linking,
splink is a Python package for probabilistic record linkage (entity resolution). Its key features are It is extremely fast. It is capable of linking a million records on a laptop in around a minute. It is
for each linkage variable, the pre-specified rate of missing and error determined the probability that a record pair agrees on a linkage variable given that the pair is a true match (mi probability); the pre-specified discriminative power determined the probability that a record pair agrees on a variable given that the pair is a true non-match (

The Data Linkage Scientist is a skillful team player with a clear track record of identifying and leveraging linkages between diverse data sets. This individual is a deliberate and systematic scientist who can apply and develop techniques for relating data through direct and indirect pathways, practice with rigor and precision, and maintain a balancedindependent point of view
In general there are two broad types of record linkage methods (i) deterministic and (ii) probabilistic. Deterministic record linkage is the process of linking information by a uniquely shared key (s). Records are matched if linkage fields agree or unmatched if they disagree.
Engineer linkage to enable scaling and repeatable use of data. Collaborate with experts across DGO to identify the best method to engineer and join data to meet customer needs. Work on the delivery of data linkage projects and report progress via appropriate governance arrangements. Work collaboratively with stakeholderstopic experts across ONS.
Probabilistic record linkage These pages present some introductory training material on probabilistic record linkage using the Fellegi Sunter model. Many of the articles are interactive. This material presents a simplified version of the model used by Splink, a piece of probabalistic linkage software for which I'm lead developer.
