Entity Anchor
Summary of Usage
An Entity Anchor is used when the anchor is a type of entity handled automatically by Semaphore’s natural language processing layer.
Entity anchors leverage the native entity extraction capabilities of the language pack in use. The entities found are not modeled in the model itself—only the type is specified.
An entity anchor can reference many different types of entities. Supported types are listed here: Information Entities.
Refer to the FACTS model for the most up-to-date Entity type taxonomy.
Note: There are no unit tests available for Entity Anchor currently.
