空间关系描述的9-交模型
The Nine-intersection Model for Describing Spatial Relation
-
摘要: 首先对4元组、9元组描述框架进行了剖析,指明了从4元组向9元组扩展的意义,同时也论述了9元组存在的缺点和不足及其产生的原因。最后,提出用空间实体的势力范围(AV)代替原9元组中的"补"作为空间实体的外部,并结合空间实体的边界(∂A)、内部(Å),构成新的基于空间实体势力范围的空间关系描述的9-交模型(简称NIV),并对其特点进行了分析。Abstract: Because the original nine-intersection model for describing spatial relation can't describe ordering relation and adjacency,it is expanded by replacing the object's complement with object's influence range.The new frame for describing spatial relation is introduced.After that, the characters of new intersection model are given.
