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 ... WebMaking the whole thing more efficient in addition to the blocking that we discussed before. So, in this very brief overview of key record linkage techniques, let me summarize that. We have deterministic matching, just a rule-based method. We have probabilistic record linkage, mostly known by a Fellegi and Sunter paper.
