In a coal preparation plant design expert system (CPDES), it is difficult to make up the knowledge bank. There is terrible huge array of knowledge for coal preparation plant design. Some of them can eveu not be listed into distinct entries with common expressing methods. Some others would be tangled and tedious if unsuitable methods were used.The thesis explained how the expert knowledge for coal preparation plant design is accePted by computer, and how the different expression of knowledge is selected according to its characteristics.展开更多

Unlike most of the current knowledge discovery methods, the comprehensive knowledge discovery considers both the spatial relations and attributes of spatial entities or objects. We introduce the theory of spatial knowledge expression system and some concepts including comprehensive knowledge discovery and spatial union information table (SUIT). In theory, SUIT records all information contained in the studied objects, but in reality, because of the complexity and varieties of spatial relations, only those factors of interest to us are selected. In order to find out the comprehensive knowledge from spatial databases, an efficient comprehensive knowledge discovery algorithm called recycled algorithm (RAR) is suggested.展开更多
