Web25. jan 2016. · History []. The initial idea of record linkage goes back to Halbert L. Dunn in his 1946 article titled "Record Linkage" published in the American Journal of Public Health. Howard Borden Newcombe laid the probabilistic foundations of modern record linkage theory in a 1959 article in Science, which were then formalized in 1969 by Ivan Fellegi … Web30. jan 2024. · 151 2. The U probabilities should come from domain knowledge about the data itself. For example, if comparing birth month, the probability of two non-matching records having the same birth month is approximately 1 / 12 (in theory). – shabbychef.
