“蛋-黄”模型的拓展研究

Popularized "egg-folk" Model

  • 摘要: 通过研究不确定数据间的拓扑关系,针对“蛋-黄”模型中46个拓扑关系内部逻辑关系不清的缺点,给出了“蛋-黄”模型的邻近拓扑关系之间的动态变化图和相应的93个拓扑关系,去掉41个含“切”的拓扑关系和6个重复的拓扑关系,仍然得到46个拓扑关系,这与Cohn的理论是一致的,在完善了“蛋-黄”模型的同时提高了其空间推理能力。

     

    Abstract: By analyzing the uncertain region topological relation,aiming at "egg-folk" model shortcoming that its logical relation among 46 topological relations are not clear,this paper obtains 93 topological relations through dynamic change of closest topological distance graph,by cutting out 41 topological relations contain tangency relation and 6 repetitive topological relations,46 topological relations are obtained too,which are consistent with Cohn theory,thus "egg-folk" model is popularized.
