  1. Exercise 2 Group 6 TDT4210 Healthcare Informatics Fall 2003

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

  3. Chosen problem • Ethanol poisoning. • Why: • Emergency guideline • Common problem • The NEL entry had enough information to base a model on

  4. Requirements for formalisms • Expressiveness • Available specifications, examples and tutorials • Available tools

  5. 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)

  6. Difficulties with EON • Few available learning materials • Protégé ontology not freely available

  7. 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

  8. GLIF 3.5 and 3.0 syntax

  9. GLIF 3.5 and 3.0 syntax

  10. GLIF 3.5 and 3.0 syntax

  11. 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….
