Formalize Knowledge

Formalize Knowledge

Knowledge Formalization is the process of translating narrative guidelines into structured knowledge that can be implemented consistently as automated CDS.  A black box stands between the published document and the computer-based decision support tool. Following poorly defined, largely non-generalizable processes, a published guideline is input into the black box and emerges in some computable format. GLIDES is particularly interested in opening and understanding what goes on in the box.

GLIDES has designed and implemented a process for knowledge formalization that balances a core of structured processes, methods and tools, with a flexible approach that can be adapted to reflect the “on the ground” realities of how clinical systems are designed, built and implemented at clinical sites.

III. Create Structured Rules

Once the guideline has been “marked-up”, GEM provides tools that work with the GEM XML file to iteratively refine the information, highlighting conditional logic, decision variables and...

In refining the logic specification, eligibility criteria, decision variables and actions types are iteratively refined and organized. Each recommendation is mapped to a
