"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. " - Deterministic record linkage
