Equivalent Domains

Equivalent domains are identified domain pairs that belong to the same organization. It is important to match these domains together to understand whether individuals communicating under both domains may be the same person.

During the Match Equivalent Domains pipeline step, our AI predicts pairs of domains that might belong to the same business entity. These predicted pairings populate on the Equivalent Domains (Priv) tab allowing you to annotate on the Annotator Decision field. Annotating an equivalent domain on the Annotator Decision field as equivalent will allow you to link different aliases with these two domains to the same entity. Each pair of domains also has an Aliases Impacted field which notes how many Aliases share both domains, and should be used to prioritize the annotation of domain pairings that have a higher Aliases Impacted count.

Requirements

Equivalent Domains can only be annotated when the Match Equivalent Domains pipeline step has a status of Ready to Apply Annotations.

Single equivalent domain annotation

To annotate Equivalent Domains:

1. Navigate to the Annotation (Priv)>Equivalent Domains (Priv) tab.

2. Filter the list to show Equivalent Domains that you have not annotated by setting Annotator Decision to (Not Set).

3. Select the Edit button on the first equivalent domain pairing in the list.

4. Review both domains, the Similarity Value field, and the Pair Frequency.
   

   Notes: Unlike other annotation objects, Equivalent Domains do not have a Prediction value. Instead, you will see a Similarity Value which gives you more data to aid in annotation.

5. On the Annotator Decision field, select either Equivalent or Not Equivalent. See Suggested annotation workflow.
   

   Notes: The AI considers Equivalent Domains not annotated on the Annotator Decision field Not Equivalent.

6. Select Save and Next to annotate the next Equivalent Domains.
   You have completed Equivalent Domain annotations when all Equivalent Domains have an Annotator Decision field value.
   

7. See Match Equivalent Domains to complete the pipeline step.

Mass equivalent domain annotation

To annotate Equivalent Domains using the Mass Actions available:

1. Navigate to the Annotation (Priv)>Equivalent Domains (Priv) tab.
2. Filter the list to show Equivalent Domains that you have not annotated by setting Annotator Decision to (Not Set).
3. Scroll through the list of Equivalent Domains and review the Similarity value. Select all of the Equivalent Domains you want to annotate as Equivalent.
   See Suggested annotation workflow.
4. Use the Annotate as Equivalent mass action button at the bottom of the page.
5. Confirm that you want to Annotate these Equivalent Domains as Equivalent. This will update the Annotator Decision field on the items selected.
6. Repeat steps 3-5 to mass annotate Equivalent Domains as Not Equivalent using the Annotate as Not Equivalent mass action.

You have completed Equivalent Domain annotations when all Equivalent Domains have an Annotator Decision field value.

See Match Equivalent Domains to complete this pipeline step.

Annotate equivalent domains fields

The following fields appear when annotating Equivalent Domains:

Field	Field type	Description	Notes
Artifact ID	Fixed-length text	A unique identifier for this specific equivalent domain pairing. This value will never change and is not editable.	Click on this value from a list to open the Equivalent Domain page where you can find more metadata on the included domains. Used to find a specific Equivalent Domains.
Domain 1	Fixed-length text	The first domain in the pairing. Extracted from the email addresses in the data set. This information will not change and you can not edit it.
Domain 2	Fixed-length text	The second domain in the pairing. Extracted from the email addresses in the data set. This information will not change and you can not edit it.
Similarity Value	Fixed-length text	How similar the two domain addresses are on a scale from 0-1.	Use this field to sort the Equivalent Domains by and prioritize annotations.
Impacted Aliases	Whole number	The number of entities in the data set predicted to have email addresses with both domains.	Use this field to sort the Equivalent Domains by and prioritize annotations.
Annotator Decision	Single choice	Equivalent domain lets you decide on whether the two domains belong to the same organization or not. Select Equivalent or Not Equivalent.
Annotated	Yes/No	Upon annotating and saving an equivalent domain this field will be populated with a checkmark. You can not edit this field.	Use this field in searches to quickly find Equivalent Domains you’ve annotated or have not. Include this field in dashboard widgets for visual representation of your annotation progress.
Privilege Project	Multiple object	This field links to the project that found this specific equivalent domain. You can not edit this field.	A, equivalent domain may link to multiple projects if it appears in multiple analyzed data sets.
Reference ID	Fixed-length text	A unique identifier used by the system. This value will never change and you can not edit it.

Suggested annotation workflow

Following is the suggested annotation workflow for Equivalent Domains. These steps should be completed in priority order:

Step	Expected Annotation	Content Type	Example	How to Locate
1	Equivalent	Two In House Domains	clientdomain1.com  clientdomain2.com	Perform the following search across equivalent domains:    Domain 1 IS LIKE [client’s domain]  AND  Domain 2 IS LIKE [client’s domain]
2	Not Equivalent	One In House Domain	clientdomain1.com  3rdpartydomain1.com	Perform the following search across equivalent domains:    Domain 1 IS LIKE [client’s domain]  AND  Domain 2 IS NOT LIKE  [client’s domain]    Separately,  Domain 1 IS NOT LIKE [client’s domain]  AND  Domain 2 IS LIKE [client’s domain]
3	Equivalent	Two Law Firm Domains	lawfirmdomain1.com  lawfirmdomain2.com	Perform the following search across equivalent domains:    Domain 1 IS LIKE law  AND  Domain 2 IS LIKE law
4	Not Equivalent	One Law Firm Domain	Lawfirmdomain1.com  3rdpartydomain1.com	Perform the following search across equivalent domains:    Domain 1 IS LIKE law  AND  Domain 2 IS NOT LIKE  law    Separately,  Domain 1 IS NOT LIKE law  AND  Domain 2 IS LIKE  law
5	Equivalent	High Similarity Value	domain1.com  domain1.net	Perform the following search across equivalent domains:    Similarity Value IS GREATER THAN 0.45000000000  Sort descending by Similarity Value
6	Not Equivalent	Remaining		All equivalent domains without an annotator decision after following the steps above.
