Abstract:

The Bigmatch program is designed for large-scale record linkage projects. The program handles several blocking strategies at a time by performing key sorts in core memory. It can process large numbers of records pairs very quickly. It can be used for matching two files or for unduplicating one file. We discuss the program, its operating features, and some application results.
