AWS API Changes

2018/11/27 - AWS Comprehend Medical - 2 new api methods

Changes The first release of Comprehend Medical includes two APIs, detectPHI and detectEntities. DetectPHI extracts PHI from your clinical text, and detectEntities extracts entities such as medication, medical conditions, or anatomy. DetectEntities also extracts attributes (e.g. dosage for medication) and identifies contextual traits (e.g. negation) for each entity.

DetectEntities (new)

Link ¶

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 .

Response Structure

(dict) --
- Entities (list) --
  
  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 that Comprehend Medical has in the detection and analysis. Attributes and traits of the entity are also returned.
  - (dict) --
    
    Provides information about an extracted medical entity.
    - Id (integer) --
      
      The numeric identifier for the entity. This is a monotonically increasing id unique within this response rather than a global unique identifier.
    - BeginOffset (integer) --
      
      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.
    - EndOffset (integer) --
      
      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.
    - Score (float) --
      
      The level of confidence that Comprehend Medical has in the accuracy of the detection.
    - Text (string) --

        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.
        
        Type (string) --
        
        The type of attribute.
