Preview API changes
Use this article to get an overview of the new API changes starting from 2023-04-15-preview version. This API change mainly introduces two new concepts (entity types and entity tags) replacing the category and subcategory fields in the current Generally Available API. A detailed overview of each API parameter and the supported API versions it corresponds to can be found on the [Skill Parameters][../how-to/skill-parameters.md] page
Entity types
Entity types represent the lowest (or finest) granularity at which the entity has been detected and can be considered to be the base class that has been detected.
Entity tags
Entity tags are used to further identify an entity where a detected entity is tagged by the entity type and additional tags to differentiate the identified entity. The entity tags list could be considered to include categories, subcategories, sub-subcategories, and so on.
Changes from generally available API to preview API
The changes introduce better flexibility for the named entity recognition service, including:
Updates to the structure of input formats: • InclusionList • ExclusionList • Overlap policy
Updates to the handling of output formats:
- More granular entity recognition outputs through introducing the tags list where an entity could be tagged by more than one entity tag.
- Overlapping entities where entities could be recognized as more than one entity type and if so, this entity would be returned twice. If an entity was recognized to belong to two entity tags under the same entity type, both entity tags are returned in the tags list.
- Filtering entities using entity tags, you can learn more about this by navigating to this article.
- Metadata Objects which contain additional information about the entity but currently only act as a wrapper for the existing entity resolution feature. You can learn more about this new feature here.
Generally available to preview API entity mappings
You can see a comparison between the structure of the entity categories/types in the Supported Named Entity Recognition (NER) entity categories and entity types article. Below is a table describing the mappings between the results you would expect to see from the Generally Available API and the Preview API.
