How do Scoring Thresholds work?
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.
