Taking improving the degree of automatic production for geo-named geographical entity data as the breakthrough point and based on the vector geographic framework data resources, a method of geo-named geographical entity automatic acquisition was proposed. Firstly, combining with the characteristics of data distribution on the vector basic geographic framework data, a strategy of automated extraction from vector data for geo-named geographical entity was designed. Then in view of repeated place name and dispersed storage of geographical data in extracted place name data, a rule of place name matching was built to eliminate repeated redundant place name data. Finally, in allusion to the characteristics of entity data organizing, an applied algorithm of geo-named geographical entity processing was constructed to implement entity data fusion by data recombination for matched geo-named geographical data to get the content results. Through those processes, the connotation uniqueness and integrality of extracted place name information could be guaranteed. Experiments on the proposed method were performed in place name extraction and place name matching and geo-named geographical entity data recombination. The experiment results showed that the proposed method not only can effectively extract the geo-name entity data, but also change the traditional data processing mode. The method made the full use of the existing geographical data and avoided duplicate construction for geo-name geographical entity.
