3.3 Matching

Entity matching is centered on entity names. Other items of data, such as associated countries and cities, are used to strengthen a possible match.

Match Rules

The match rules in Oracle Financial Services Customer Screening are organized by the level of entity name match, with the strongest name matching rules at the top of the decision table.

Optional elimination rules exist that allow lower risk matches to be suppressed.

The following match rules are involved in entity screening:

• The elimination rules, which are used in the rule templates to suppress the generation of lower risk matches - for example, low quality matches against list records with a low-risk score. The elimination rules may be moved up and down in order to change where they apply.
• The entity name matching rules. Entity name matching rules are organized by the level of entity name match, with the strongest matching rules placed at the top of the decision table.

  Note:

  This means that the match rules are not ordered by strength across all identifiers. For example, a weaker match rule that is strengthened by matches on City and Country is likely to be a stronger overall match than a strong match rule with strongly contradictory data in the other fields.
• The loose entity matching rules. These are also based around entity name matching, but identify looser matches and are not enabled by default. These rules are likely to result in a large number of false-positive matches and are most likely to be of use when screening against sanctions lists, where it is important that no true matches are missed.

For the sake of clarity, match rules are divided into groups, as shown below:
