ComprehendMedical.Client.detect_entities_v2(**kwargs)¶Inspects the clinical text for a variety of medical entities and returns specific information about them such as entity category, location, and confidence score on that information. Amazon Comprehend Medical only detects medical entities in English language texts.
The DetectEntitiesV2 operation replaces the DetectEntities operation. This new action uses a different model for determining the entities in your medical text and changes the way that some entities are returned in the output. You should use the DetectEntitiesV2 operation in all new applications.
The DetectEntitiesV2 operation returns the Acuity and Direction entities as attributes instead of types.

Response Structure
The collection of medical entities extracted from the input text and their associated information. For each entity, the response provides the entity text, the entity category, where the entity text begins and ends, and the level of confidence in the detection and analysis. Attributes and traits of the entity are also returned.
Provides information about an extracted medical entity.
The numeric identifier for the entity. This is a monotonically increasing id unique within this response rather than a global unique identifier.
The 0-based character offset in the input text that shows where the entity begins. The offset returns the UTF-8 code point in the string.
The 0-based character offset in the input text that shows where the entity ends. The offset returns the UTF-8 code point in the string.
The level of confidence that Comprehend Medical; has in the accuracy of the detection.
The segment of input text extracted as this entity.
The category of the entity.
Describes the specific type of entity with category of entities.
Contextual information for the entity.
Provides contextual information about the extracted entity.
Provides a name or contextual description about the trait.
The level of confidence that Comprehend Medical; has in the accuracy of this trait.
The extracted attributes that relate to this entity.
An extracted segment of the text that is an attribute of an entity, or otherwise related to an entity, such as the dosage of a medication taken. It contains information about the attribute such as id, begin and end offset within the input text, and the segment of the input text.
