Towards Parameter-free Blocking for Scalable Record Linkage
Linking or matching databases is becoming increasingly important in many data mining projects, as linked data can contain information that is not available otherwise, or that would be too expensive to collect. A main challenge when linking large databases is the complexity of the linkage process: potentially each record in one database has to be compared with all records in the other database.
