Abstract:
Relationships between decision-support systems and knowledge representation are examined
from three different points of view: the characteristics of medical decisions that
might influence the selection of appropriate knowledge representations, – the extent
to which different knowledge representations can support efficient medical decisions
and, – the validation of knowledge hypotheses through the practice of decision support
systems. A three-level model of knowledge representation is proposed that includes
a contextual, a conceptual and a computational level. Taking into consideration the
context that leads to the selection of a given representation raises the issue of
multiexpertise and multirepresentation modeling. Implementation of decision support
systems as sets of cooperative agents and integration in the health information systems
are considered.
