BigMatch: A Program for Extracting Probable Matches from a Large File

William E. Yancey

KEY WORDS: record linkage, software


We present documentation for running the BigMatch program, a new record linkage tool for use in matching a very large file against a moderate size file. For each of several blocking criteria, the program can extract likely matching record candidates from the large file without requiring sorting of either file.
