AB PROTEGE-II is a suite of tools and a methodology for building
knowledge-based systems and domain-specific knowledge-acquisition tools.
In this paper, we show how PROTEGE-II can be applied to the task of
providing protocol-based decision support in the domain of treating
HIV-infected patients. To apply PROTEGE-II, (1) we construct a
decomposable problem-solving method called episodic skeletal-plan
refinement, (2) we build an application ontology that consists of the
terms and relations in the domain, and of method-specific distinctions
not already captured in the domain terms, and (3) we specify mapping
relations that link terms from the application ontology to the
domain-independent terms used in the problem-solving method. From the
application ontology, we automatically generate a domain-specific
knowledge-acquisition tool that is custom-tailored for the application.
The knowledge-acquisition tool is used for the creation and maintenance
of domain knowledge used by the problem-solving method. The general goal
of the PROTEGE-II approach is to produce systems and components that are
reusable and easily maintained. This is the rationale for constructing
ontologies and problem-solving methods that can be composed from a set
of smaller-grained methods and mechanisms. This is also why we tightly
couple the knowledge-acquisition tools to the application ontology that
specifies the domain terms used in the problem-solving systems. Although
our evaluation is still preliminary, for the application task of
providing protocol-based decision support, we show that these goals of
reusability and easy maintenance can be achieved. We discuss design
decisions and the tradeoffs that have to be made in the development of
the system.
