| 摘 要： | 借鉴数据抽取的相关理论,提出一种面向专业管线抽取综合管线数据的语义映射机制建立方法,以燃气管线数据为例,在剖析两者间的语义、几何、属性、拓扑关系等方面差异的基础上,设计综合管线和燃气管线的数据结构和数据描述模型,构建数据自动转换规则,建立两者间的语义映射机制,进而为实现了燃气管线数据到综合管线的“一站式”抽取打下基础.

| Abstract: | This paper proposes a kind of semantic mapping mechanism about data extraction ofrom professional line to comprehensive pipeline. Firstly, we have discussed, the semantic differences and similarity of gas pipeline and complex pipeline, and then we have set up the geometry, topology and semantic rules. Secondly, we have design the dynamic mapping algorithm adaptive to the geometry types. Lastly, By taking gas pipeline for example, the semantic mapping mechanism between special pipeline from complex pipeline, to be achieved. |
