Exercise 2

Group 6

TDT4210 Healthcare Informatics

Fall 2003


Background

Background

  • Guidelines formalisms may be everything from computer interpretable to only human readable.


Chosen problem

Chosen problem

  • Ethanol poisoning.

  • Why:

    • Emergency guideline

    • Common problem

    • The NEL entry had enough information to base a model on


Requirements for formalisms

Requirements for formalisms

  • Expressiveness

  • Available specifications, examples and tutorials

  • Available tools


Eon dharma

EON/Dharma

  • Network based formalism

  • Our first choice.

  • Because:

    • Very expressive

    • Widely adopted

    • EON is both an interactive and critiquing system (can reason about record information)


Difficulties with eon

Difficulties with EON

  • Few available learning materials

  • Protégé ontology not freely available


New choice glif 3

New choice: GLIF 3

  • Guideline Interchange Format. Used for transferring guidelines between systems.

  • Network based formalism

  • Protégé ontologies freely available.

    • Example guidelines to learn from

    • Hard to use Protégé 2000 for editing (diagram vs. graph)

  • Used regular structured drawing program


Exercise 2

GLIF 3.5 and 3.0 syntax


Exercise 2

GLIF 3.5 and 3.0 syntax


Exercise 2

GLIF 3.5 and 3.0 syntax


Evaluation

Evaluation

  • Took too long to choose formalism

  • GLIF is not just used for modelling figures, but that is all we have modelled in this case study

  • Some steps might be decomposed a little bit further

  • We are not doctors….
