WebJan 6, 2024 · When linking massive data sets, blocking is used to select a manageable subset of record pairs at the expense of losing a few matched pairs. This loss is an important component of the overall linkage error, because blocking decisions are made early on in the linkage process, with no way to revise them in subsequent steps. Yet, … Webdate set are examined in detail during record linkage. These blocking goals represent a trade off. On the one hand, the goal of record linkage is to find all matching records, but the process also needs to scale. This makes blocking a challeng-ing problem.
