  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.
