► Quantitative► Numerical data:
► 2mm, 2.4V, between 4 and 5 feet
► Unambiguous tokens
► Main problem is accuracy at initial capture
► Numerical analysis (e.g. statistics) well understood
► Examples:► How big is this breast lump?
► What is the average age of patients with cancer ?
► How much time elapsed between original GP referral and first appointment at the hospital ?
Describe the WorldDescribe the World
► Qualitative► Descriptive data
► Cold, colder, blueish, not pink, drunk
► Ambiguous tokens
► What’s wrong with being drunk ?
► Ask a glass of water.
► Accuracy poorly defined
► Automated analysis or aggregation is a new science
► Examples► Which patient is more psychotic ?
► What is the typical microscopic appearance of these tumours ?
► How bad are the side effects of chemotherapy ?

► Concept orientation► Separate language (terms) and concepts (codes)
► Concept permanence► Never re-use a code (‘retire’ it)
► Nonsemantic concept identifiers► Separate the code from the path
► Polyhierarchy► Allow one concept to be classified in multiple ways
►Gout can be both a metabolic disease and an arthritis
Barriers to interoperabilityBarriers to interoperability Cimino’s Desiderata (2)Cimino’s Desiderata (2)
►Formal Definitions► i.e ‘Be compositional’
►Reject ‘Not elsewhere classified’► concept permanence and NEC
►Multiple granularities► Organ, tissue, cellular, molecular
► Grades, types, classes of diseases
► Special clinical criteria
►Multiple consistent views► Allow different organisations
►e.g. functional, anatomical, pathological
Barriers to interoperabilityBarriers to interoperability Cimino’s Desiderata (3)Cimino’s Desiderata (3)

Pros and ConsPros and Cons►An invaluable resource, but...
► No better than the vocabularies which are mapped
►Limited detail for patient care
►Unreliable for indexing or abstraction of knowledge
►Best for relating everything to MeSH for indexing literature
► Still limited by combinatorial explosion
►Still can’t cope with fractal knowledge
►Not extensible - no help in building or extending terminologiese
►No help in reorganising existing terminologies to re-use for new purposes
►Top down
► Information still implicit
►Minimal help with software
► No help with data capture, user interfaces

Caveats:Caveats:
Language is slipperyLanguage is slippery
►Human cognition makes it look easy► Logic fails to capture it
►Classification is easy until you try to do it
►Trying since Aristotle in the West and Ancient Chinese in the East
►Words/Concepts mean what a community decides they mean
► Does a chimpanzee have four hands?
► Is a prion alive?
► Is surgery on the ovary a kind of ‘Endocrine surgery’?
►Easier to agree on the concrete than the abstract► Easy to agree on useful abstractions and generalisations
►Harder to agree on how to name them
