Computer technology has become an important part of many aspects of modern life, and the role of computers in health care will undoubtedly increase in the future. One of the most popular fields in medical informatics involves decision support systems (DSSs), which focus on providing the decision maker with accurate data, factual medical knowledge and problem-solving support. A common observation when building DSSs is that knowledge bases over time tends to become large and complex. Maintenance and extension of knowledge bases is a difficult task and time consuming work. Furthermore, no single institution can ever define a knowledge base which covers all aspects of medicine. Therefore, it is necessary and desirable to share knowledge among institutions.
An approved standard (Defining and Sharing Modular Knowledge Bases ASTM E-1460) of medical knowledge representation called Arden Syntax constitutes an attempt to facilitate medical knowledge sharing among institutions, and to enhance the writabillity and readabillity of medical knowledge.
In this thesis, development of methods for realizing the Arden Syntax in building DSSs is reported. Essential components in building DSSs have been analysed. The design and functions of MLM editors are described. An MLM pre-compiler which after syntax checking, translates MLMs into C++ code, evoke definition til.ble, and trigger information table is dernonstrated. A prototype system has been built in order to show the feasibility of the developed rnethods.
