Blocking record linkage
Record linkage (also known as data matching, data linkage, entity resolution, and many other terms) is the task of finding records in a data set that refer to the same entity across different data sources (e.g., data files, books, websites, and databases). Record linkage is necessary when joining different … See more "Record linkage" is the term used by statisticians, epidemiologists, and historians, among others, to describe the process of joining records from one data source with another that describe the same entity. … See more In an application with two files, A and B, denote the rows (records) by $${\displaystyle \alpha (a)}$$ in file A and $${\displaystyle \beta (b)}$$ in file B.
