FEATURE: Extended Cross-Referecing stage

[catileptic]

Is your feature request related to a problem? Please describe. A user may want all the Mentions in an investigation to be cross-referenced against Mentions and Entities in other investigations.

Currently, in Investigations, detected names in Mentions are reified and converted into proper LegalEntitys, and the cross-referenced.

Describe the solution you'd like Extended Cross-Referecing would be an optional stage, that would take all Mentions and cross-referrence them against all other Mentions and all other entities in Aleph. It wouldn't neccesarily create Entities for each Mention.

Describe alternatives you've considered An alternative to this is to download the Mentions, and create Person or LegalEntity entities through a script. Then, these entities would be uploaded back into the investigation in Aleph and a cross-reference would be triggered.

alephclient stream-entities -f ... -s Mention

or

alephclient stream-entities -f ... -s Analyzable

This required manual intervention, whereas an additional stage could be enabled for the ingestion of several Investigations at a time by an Aleph admin, and then turned off. This would work fine for smaller Aleph instances.
