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
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….
