• Clear recording and appropriate interpretation of context is essential for safe use and accurate analysis of

  . 
• The context in which a 

  Gloss
  t concept

   is used can be represented in various ways. Some of the possible representation are shown in the examples section below.
• Appropriate interpretation of different representations of context can be facilitated by 

  Gloss
  t terminology binding

   techniques that resolve multiple

   into a common

  .

Examples

• A disease such as "asthma" might be referred to in various contexts.
  • A current presenting problem needing treatment
  • A past history recorded during assessment for treatment of another condition
  • A family history recorded routinely during a consultation
• Family history of asthma can be recorded using 

  Gloss
  t SNOMED CT

   in several ways three of which are illustrated here.

  • Use of a single concept from the 

    Gloss
    t situation with explicit context

     

    Gloss
    t domain

    :

    
    

    Scg expression
    t Border solid ShowFormat block
    160377001 |Family history: Asthma (situation)|

  • Application of a 

    Gloss
    t context wrapper

     to the concept

    Concept
    t 195967001 Asthma (disorder)

    :

    57177007 |Family history with explicit context (situation)|: {246090004 |Associated finding (attribute)| = 195967001 |Asthma (disorder)|}

  • Use of features of an 

    Gloss

     model, such as separate record sections for information with different contexts.

  • Based on the definitions of these concepts, a 

    Gloss
    t description logic classifier

     will infer that first two representations above have precisely the same meaning. The third representation can be similarly resolved if the "Family History Record Section" has a model or meaning binding to the

     wrapper.
