16. Related Work
• Not much related work:
• Lobach and Kerner. A systematic process for
converting text-based guidelines into a linear algorithm
for electronic implementation
− Very conceptual, no tooling
• Grammar-based Approaches: irrelevant tools
− input texts do not adhere to grammatical rules

19. Demo

20. Demo
• Clinical guidelines published as plain text
• Formalized using the flowcharts using
only a subset of the notation
• Flowcharts are published as images only
20

21. Demo
• Annotation tool used to annotate
title, observations, action/treatments, info
rmation/explanation
21

22. Demo
• The annotations are transformed to a
flowchart skeleton model
22

23. Demo
• The flowchart is manually refined
23

24. Demo
• The flowchart is transformed into a
Clinical Decision Support System app

• Improvements:
• Binary decisions in flowchart can produce long
sequences of questions
− Metamodel Extensions
