Master Index Match Engine Reference

Weight Distribution Method

Each record pair in the master index application can be classified into three categories: matches, non-matches, and potential matches. In general, the distribution of records is similar to the graph shown in Figure 6. Your goal is to make sure that very few records fall into the False Matches region (if any), and that as few as possible fall into the False Non-matches region. You can see how modifying the thresholds changes this distribution. Balance this against the number of records falling within the Manual Review section, as these will each need to be reviewed, researched, and resolved individually.
