Record linkage of millions of individual health records for ethically-approved research purposes is a computationally expensive task. Blocking methods are used in record linkage systems to reduce the number of candidate record comparison pairs to a feasible number whilst still maintaining linkage accuracy. New blocking methods have been implemented recently using high-dimensional indexing or clustering algorithms.
