Abstract:
|
Record linkage computation under Fellegi-Sunter theory depends on the values of conditional pattern probabilities. Using good parameter values tailored to the given data set can significantly reduce the number of record pairs requiring clerical review. Under the naïve Bayes (conditional independence) model, these parameters can be computed using the EM algorithm using pattern counts as input data, without using training data. Alternatively we consider using a Bayesian model and MCMC to compute a distribution of the parameters also without using training data. We compare the results to the EM algorithm output.
