Abstract:
If knowledge sharing between people in an organisation is to be encouraged, new types of systems are needed to transfer domain knowledge and problem-solving strategies from an expert to the end users and, thereby, make the knowledge available and applicable in a specific domain. If it is to be possible to apply the knowledge in the organisation, the systems will need a means of illustrating the reasoning strategies involved in interpreting the knowledge to arrive at the conclusions drawn. One solution is to incorporate different diagrams in knowledge management systems to assist the user to comprehend the reasoning strategies and to better understand the knowledge required and gained. This paper describes the manners by which knowledge management systems can facilitate transfer of problem-solving strategies from a domain expert to different kinds of end users. With this objective in mind, we suggest using visualization, graphical diagrams and simulation in conjunction to support the
transfer of problem-solving strategies from a domain expert to the end users. Visualization can support end users, enabling them to follow the reasoning strategy of the system more easily. The visualization discussed here includes static and dynamic presentation of the rules and facts in the knowledge base that are used during execution of the system. The static presentation illustrates how different rules are related statically in a sequence diagram in the Unified Modeling Language (UML). The dynamic presentation, in contrast, visualizes rules used and facts relevant to a specific consultation, i.e., this presentation depends on the input inserted by the users and is illustrated in a collaboration diagram in the UML. Utilising these diagrams can support the sharing and reuse of the knowledge and strategies used for handling routine tasks and problems more efficiently and profitably whilst minimizing potential for loss of knowledge. This is important when experts are not available on the spot. These diagrams can also be used for the organisation and the disseminating of knowledge by locating experts in an organisation, which is important when these are to be relocated in large organisations or geographically distributed.
