Applying probabilistic record linkage algorithms
Deduplication is one of the key challenges in MDM and refers to the accurate identification and linkage of duplicate records. Unlike the case of email deduplication applied to a single field, as you saw in the previous chapter, it is often necessary to deduplicate records based on multiple fields that may be similar. In this section, we’ll see how to approach a case of deduplication using probabilistic record linkage in Python, R, and Power BI.
Applying probabilistic record linkage in Python
One of the most popular open-source Python libraries designed for probabilistic record linkage is Splink (https://github.com/moj-analytical-services/splink). It simplifies the process of implementing probabilistic record linkage by providing an easy-to-use and intuitive interface. It can efficiently handle large datasets, making it suitable for both small and large data applications.
