Second, there is a refinement stage that involves evaluating the prototype, refining the knowledge base, modifying the design and re-evaluating the improved system.
Further, there must be the analytic capacity and the commitment to use and refine the knowledge gained.
The dynamic nature of the plug-in allows updates in the knowledge base to refine application semantics to improve the quality of the query response.
Our review has begun to extend the knowledge base by identifying and refining some of the middle-range theories that explain the 'how', 'why' and 'in what circumstances' questions about Internet-based medical education.
Third, terminological cycles and inconsistencies are manually eliminated and, in the last step, the knowledge base built this way is incrementally refined by a medical expert.
The knowledge base resulting from the shared shaping of the research experiment, can be used to further develop and refine the current research experiment, but also future experiments.
Read the articles in the knowledge base.
Knowledge maintenance in RDR is simplified with an interface that guides a domain expert in developing the knowledge bases and incrementally refining them as required.
The approach extends a combined rule and case-based knowledge acquisition technique known as Multiple Classification Ripple Down Rules to allow multiple users to collaboratively view, define and refine a knowledge base over time and space.
The accumulated and refined knowledge base includes, but is by no means restricted to, weather forecasts and precipitation indicators, livestock health problems, important poisonous or injurious plants, range degradation and drought mitigation strategies (e.g. Dube and Sekhwela 2008 Cassidy et al. 2011; Mogotsi et al. 2011b, Motlhanka and Nthoiwa 2013).
