Exclusions
You can exclude specific types of entity and link, and specific entities, from a search for a connecting network. Use exclusions to configure or refine the search, and to test hypotheses.
To configure or refine the search, you might add exclusions in the following scenarios:
- A chart might contain telephone call and associate links between people. To discover whether a network of communication joins several people, you can exclude the Associate link type. You can exclude an item type at any time.
- You can exclude specific people that you know are not involved in an incident that you are investigating.
- You might know that several people are employed by the same company. To avoid this known association and search for an alternative network that connects the people, you can exclude the company.
You can test hypotheses such as whether freezing a specific bank account prevents the movement of funds between several other accounts of interest. After Analyst's Notebook identifies a connecting network, you can exclude intermediate entities that you suspect might play a central role, and then search again. The next search indicates whether an alternative network can join the entities of interest.
You can exclude a specific entity only after Analyst's Notebook identifies it as an intermediate entity in a connecting network.
