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

The research shows that some valuable spatial correlation patterns can be further found from the clustering result comparison with multi-themes, based on traditional spatial clustering as the first step. Those patterns can tell us what relations those themes have, and thus will help us have a deeper understanding of the studied spatial entities. An example is also given to demonstrate the principle and process of the method.展开更多

The language is closely related to Dani, Walak, and Nggem. It is an SOV language typology that has a complex morphological system. Four spatial dimensions are morphosyntactically coded in elevative deixis, which are steepness/non-steepness distinction, proximity/distality distinction, adverbial/attributive expressions, and vertical/horizontal plane. This paper discusses the grammatical operation of a set of two-term system： ei ＂up＂ and ou ＂down＂ that serves as the basic forms for the elevational deixis in Wano.展开更多
