INTEGRATION OF DATA-DRIVEN DECISION-SUPPORT INTO THE HELIOS ENVIRONMENT

The development of large-scale, clinically accepted decision support s ystems (DSS) calls for powerful and commonly available methods and too ls for knowledge acquisition, system realisation, and knowledge base m aintenance. The paper addresses problems associated with the integrati on of knowledge-based systems within the clinical setting with special reference to (i) data driven decision support, (ii) the Arden Syntax as a knowledge representation format and, (iii) the HELIOS software en gineering environment. Architecture of a DSS based on Arden Syntax and its integration in the HELIOS environment are presented. Realisation of the DSS is discussed in relation to client-server architecture and object-oriented databases, which are essential concepts of the HELIOS environment. Sharability and reusability of the knowledge, together wi th commonality of used software tools are also discussed.
