Matching Thresholds

How do Scoring Thresholds work?

Matching Thresholds

The matching logic thresholds are explained below:

Name Matching Logic

W2 use a numbered scoring system for name matching.

•    A score of 100 means that Alert Profile name matches exactly the Client record name.

•    A score of 90 means that Alert Profile name contains Client record name in same order with no gaps.

•    A score of 85 means that Alert Profile name contains Client record name in same order.

•    A score of 80 means that Alert Profile name contains Client record name in any order.

Date of Birth Matching Logic

For Date of Birth matching a numbered scoring system 0-100 (100 being a total match) with a weighting towards Year of Birth and positive/negative depending on factors that match/mismatch is used: 

•    Year of Birth match is +60, Year of Birth mismatch is -60

•    Month of Birth match is +20, Month of Birth mismatch is -20

•    Day of Birth match is +20, Day of Birth mismatch is -20

•    Missing information in any of the above fields is +/-0

When calling records using a score on either Name and/or Date of Birth only records matching that score or greater will be returned. In some cases the Date of Birth held within Sanctions records is not in a recognisable format, such as ‘circa 1960’ or ‘between 1965 and 1970’. In these, and other similar cases we treat the Date of Birth as missing for scoring purposes.
