Abstract
There are a wide variety of computer applications that deal with various aspects of
medical language: concept representation, controlled vocabulary, natural language
processing, and information retrieval. While technical and theoretical methods appear
to differ, all approaches investigate different aspects of the same phenomenon: medical
sub language. This paper surveys the properties of medical sublanguage from a formal
perspective, based on detailed analyses cited in the literature. A review of several
computer systems based on sublanguage approaches shows some of the difficulties in
addressing the interaction between the syntactic and semantic aspects of sUblanguage.
A formalism called Conceptual Graph Grammar is presented that attempts to combine
both syntax and semantics into a single notation by extending standard Conceptual
Graph notation. Examples from the domain of pathology diagnoses are provided to illustrate
the use of this formalism in medical language analysis. The strengths and weaknesses
of the approach are then considered. Conceptual Graph Grammar is an attempt to synthesize
the common properties of different approaches to sublanguage into a single formalism,
and to begin to define a common foundation for language-related research in medical
informatics.
