Deterministic record linkage
WebSep 24, 2024 · In the most basic version of deterministic record linkage, the weight for a pair is simply the number of linking variables with exact agreement, yielding values ranging from 0 to the number of linking variables. Probabilistic weight determination uses statistical modeling based on estimated probabilities that records match, ... WebExact matching can be divided into two subtypes: deterministic record linkage and probabilistic record linkage, as illustrated by figure 3.4.5.1 below. Description for Figure 3.4.5.1. The figure is a hierarchical diagram showing the relation between the different types of …

Deterministic algorithms determine whether record pairs agree or disagree on a given set of identifiers, where agreement on a given identifier is assessed as a discrete—“all-or-nothing”—outcome. Match status can be assessed in a single step or in multiple steps.

WebMar 25, 2024 · The “Deterministic record linkage” section discusses rule- and similarity-based approaches, which are popular due to their interpretability and scalability. The “Probabilistic record linkage” section introduces probabilistic record linkage methods that have led to many advancements and extensions.
WebMar 28, 2024 · Deterministic record linkage is a good option when the entities in the data sets have identified common identifiers with a relatively high quality of data. Probabilistic matching is a statistical approach in measuring the probability that two records represent the same subject or individual based on whether they agree or disagree on the various ... WebIn deterministic linkage, pairs of records are classified as links if their linking variables predominantly agree, or as non-links if they predominantly disagree. There are 2n possible link/non-link configurations of n fields, so probabilistic record linkage uses M and U probabilities for agreement and disagreement between a range of linking ...
WebSep 22, 2024 · By 1970, at least 100 papers were being published on record linkage (deterministic and probabilistic) each year. From about 1970 to 1999, most of the record linkage research was occurring at national statistics agencies. By the late 1980s, over 300 papers were being published annually, and the first books related to record linkage …
