IM Relationship Resolution Information Center, Version 4.2

Role alert rules

Role alert rules are user-defined rules that identify one or more roles that cannot exist in a single entity or cannot be linked between multiple entities. During entity resolution, if the criteria for a role alert rule is met, the system generates a role alert.

Although most role alert rules specify when roles conflict, you can also define a role alert rule where an entity that is assigned a role knows another entity that is assigned the same role. For example, you might find it interesting to know whenever your customers know one another, and define a role alert rule (customer knows customer) that generates a role alert whenever one customer entity relates to another customer entity in the entity database.

Because entities consist of multiple records (often from different data sources), and because roles are typically assigned by data source, one entity can be assigned multiple roles. So it is also possible to define a role alert rule that generates a role alert whenever one entity is assigned both the customer role and the bad guy role, based on incoming data.

Note: Keep in mind that when a system is configured to use a large number of roles, the number of role alert rules increases exponentially.

Although the system detects each relationship that violates a role alert rule, by default it only reports one role alert for each entity. For example, if the system detects that an entity that is assigned an employee role is related to two different vendor entities, and a role alert rule is configured to generate a role alert when employee knows vendor, both conflicts are detected and written to the database, but by default, only one role alert is reported.

When configuring role alert rules, you can also specify alert filters that govern whether the system re-alerts (generates a new alert) when new identities or new data source codes are introduced to existing entities involved in a previously generated alert.
