基于常识的空间推理研究

Research on Spatial Reasoning Based on General Knowledge

空间推理是空间信息智能化处理的难题之一,目前的空间推理过程缺乏柔性化与智能化的一个重要原因就是不能有效利用常识。该文中阐述常识、常识推理及常识的表示,研究空间推理、基于常识的空间推理的关键技术及其在空间信息处理中的作用。最后结合基于常识的空间推理的空间可视性分析示例,提出利用空间常识提高空间信息处理系统智能性的思路。

Spatial reasoning is the process which utilizes spatial theory and spatial information to analyze and solve problems, it plays a key role in the procedure of spatial information intelligent process. There is a lack of flexibility and intelligence in the existing spatial reasoning process,and an important cause to this is that the existing spatial information reasoning process can＇t utilize spatial general knowledge effectively. In this paper, the general knowledge and its represent were discussed. Based on this, spatial soning,and the key technologies in spatial commonsense reasoning were studied, a new approach to improve the spatial information intelligence process illustrated with region visibility analysis based on spatial general knowledge was proposed. General spatial knowledge will play a key role for the increment of spatial information value in the future intdligent spatial reasoning process,so there is much further work that should be done both in the mechanism of general spatial knowledge formulation and in the application research of general spatial knowledge process for spatial reasoning.
