IMIA Working Group 6

Medical Concept Representation

Focus of Meeting:

  • New role of ontological research
          • for new age of biomedical informatics

Scientific developments:

foundational issues

rather than operational questions

  • Long-term view:
          • ensure development of robust
          • biomedical ontologies for the future

What will be the take home message?

What are the problems?

We have established biomedical informatics

Is it a service?

Is it a new biomedical science?

If a science

What is its theoretical foundation?

What is its methodology?

Are theory and ontological methodology applied in

slide31

Attributes of Science

Science has

a.) theories on basis of which hypotheses can be formulated

b.) methodology which can test the hypotheses

Best hope: Ontology

slide32

Need for theories and methodology

What is ontology ?

Smith (1996):

“the science which deals with the nature and organization of reality”

Grenon, Smith & Goldberg (2004)

“An ontology grasps the entities which exist within a given portion of the world at a given level of generality. It includes a taxonomy of the types of entities and relations that exist in that portion of the world seen from a given perspective.”

Ontological theories

derive from the philosophy of reality

Ontological methodology

creates an artifact which depicts a portion of the world

seen from a given perspective

slide33

Need for theories and methodology

What is ontology ?

first meaning:

Smith (1996):

“the science which deals with the nature and organization of reality

Grenon, Smith & Goldberg (2004)

“An ontology grasps the entities which exist within a given portion of the world at a given level of generality. It includes a taxonomy of the types of entities and relations that exist in that portion of the world seen from a given perspective.”

second meaning:

an artifact

projects to a given domain of reality

created through the application of

principles and methods of ontological science

slide34

Why base an ontology on reality?

Ambiguity

  • any domain discourse is full with it
  • humans are adapt at dealing with it

- printed page tolerates it

  • computational inference will be

crippled by it

slide35

Why base an ontology on reality?

Ambiguity

  • any domain discourse is full with it
  • humans are adapt at dealing with it

- printed page tolerates it

  • computational inference will be

crippled by it

Conclusion:

- we have to base ontology on reality

- need to take a new look at reality

slide36

slide75

How do we represent pathological continuants?

Will the processes remain

normal?

slide76

Can we propose a theory of

biological processes?

Rationale for theory of continuants:

based on gene expression of dependent continuants

compatible with theory of OBR

Rationale for theory of processes:

need to formulate a hypothesis

evaluate it through instantiation of

physiological and pathological processes

slide77

Can we propose a theory of

biological processes?

Start with a hypothesis:

A process is an occurrent which is realized through the conversion of physical energy of one kind to another or to a change in structural order.

slide78

Theory of biological processes

Hypothesis:

A process is an occurrent which is realized through the conversion of physical energy of one kind to another or to a change in structural order.

Rationale:

processes involve

movement of their participants

caused by some force

generated by dissipation of energy

slide84

How do we classify processes?

Definition

  • Process is
  • - an occurrent which is realized through the conversion of physical energy of one kind to another or to a change in structural order
  • - a transformation of one state of an occurrent into another state.
    • - a change in the values of the set of attributes that define a state.

Definition

  • Process is
  • - an occurrent which is realized through the conversion of physical energy of one kind to another or to a change in structural order.
  • - a transformation of one state of an occurrent into another state.
    • - a change in the values of the set of attributes that define a state
  • State is
  • a dependent continuant specified by the values of a set of attributes.

Testing the ‘Process’ hypothesis

Hypothesis:

A process is an occurrent which is realized through the conversion of physical energy of one kind to another or to a change in structural order.

  • Rationale:
  • processes involve
  • movement of their participants
  • caused by some force
  • generated by dissipation of energy
  • Testing of hypothesis:
      • rooted in non-equilibrium thermodynamics
      • first classification trial yields results
      • intuitive at the operational level
      • conform to single inheritance
