Evaluating String Comparator Performance for Record Linkage

RRS2005-05
William E. Yancey
Component ID: #ti712620520

Abstract

We compare variations of string comparators based on the Jaro-Winkler comparator and edit distance comparator. We apply the comparators to Census data to see which are better classifiers for matches and non-matches, first by comparing their classification abilities using a ROC curve based analysis, then by considering a direct comparison between two candidate comparators in record linkage results.
