GWSM and Record Linkage
Data from different sources are increasingly being combined to augment the amount of information that we have. Often, the databases are combined using record linkage. When the files involved have a unique identifier that can be used, the linkage is done directly using the identifier as a matching key. When there is no unique identifier, a probabilistic linkage is used. In that case, a record on the first file is linked to a record from the second file with a certain probability. Then, a decision is made on whether this link is a true link or not. Note that this process usually requires a certain amount of manual resolution.
