An Unbiased Estimator for Hamming LSH Blocking
Record linkage has recently received much attention as a result of the many data sources that are nowadays available and need to be integrated to enable large-scale data analyses. Accurately estimating the proportion of matching record pairs, and obtaining a sample of such pairs, would greatly assist data custodians to compile appropriate business plans. This paper presents the first sampling method that is specifically tailored to the particular characteristics of the Hamming Locality-Sensitive Hashing (LSH) Blocking. This sampling method estimates the proportion of the number of matching record pairs between two data sets, with a specified acceptable level of error and a certain probabilistic confidence. Through experimental evaluation using four real-world data sets, we show the effectiveness and efficiency of our approach in estimating the number of matching pairs in record linkage tasks.
