Record Linkage is the process of identifying and unifying records from various independent data sources. Existing strategies, which can be either deterministic or probabilistic, often fail to link records satisfactorily under uncertainty. This paper describes an indigenously (locally) developed fuzzy linkage method, based on fuzzy set techniques, which can effectively account for this uncertainty prevalent in the disparate data sources and address the shortcomings of the existing approaches. Extensive testing, evaluation and comparisons have demonstrated the efficacy of this fuzzy approach for record linkages.
