Measure the worldMeasure the world

► 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 ?

Barriers to interoperabilityBarriers to interoperability

Cimino’s Desiderata (1)Cimino’s Desiderata (1)

► 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)

► Represent context► Family history, risk, source of information

► Evolve gracefully► Allow controlled changes

► Recognise redundancy (equivalence)► ‘Carcinoma’ + ‘Lung’ ?=? ‘Carcinoma of the lung’

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
