Record Linkage: Deterministic vs Probabilistic approaches

WebDeterministic Linkage Methods. 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. 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 ...

WebDeterministic record linkage is often portrayed as a method which doesn’t account for missing values and partial agreements and yields less success than probabilistic methods. For example, Whalen et. al.2 believe that “probabilistic matching produces more links than other methods and that many of these links are missed by other methods.
