IM Relationship Resolution Information Center, Version 4.2

Candidate lists

Candidate lists are the lists of entities that have the potential to match the incoming identity record. The candidate list is built by retrieving those entities that share attributes with the incoming identity, based on the attributes that are specified in the candidate builder configuration.

The entity resolution process only uses the entities on the candidate list for resolving entities and resolving relationships.

Because entity resolution and relationship detection are determined based on attributes, you want to carefully consider the attributes in your data sources to determine which attributes create the strongest candidates.

After the candidate list is generated, the entity resolution process compares the incoming identity to the first candidate on the list using the configured resolution rules. The system uses the resolution rules, in order, to compute a resolution score that represents how closely the incoming identity attributes match the attributes of the candidate entity. If the incoming identity attributes meet or exceed the resolution score for that rule, the incoming identity record is resolved into the candidate entity.

If the resolution score does not meet or exceed the resolution score set for that resolution rule, the system goes to the next resolution rule until the incoming identity record has been resolved into a candidate entity or all resolution rules have been exhausted.

If the incoming identity record is not resolved into an existing entity, the system resolves the record into a new entity and stores the new entity in the entity database.
