运用Q统计分析网络空间现象关联模式

Spatial Association Analysis of Network SpatialPhenomena with the Q Statistic

  • 摘要: 目的 空间关联模式的分析和发现是空间数据挖掘领域关注的热点问题。介绍了Q 统计的概念,并将距离测度定义为网络最短路径。应用 Q统计对一种网络空间现象———酒店的空间关联模式进行了分析。研究结果从空间数据挖掘的角度验证了酒店间的聚集效应。同时,也说明了 Q 统计在进行网络空间现象关联模式分析中是有效的。最后对欧式空间与网络空间下的 Q统计进行了比较。

     

    Abstract: Objective The analysis and discovery of spatial association is a hot issue in the field of spatial data min-ing.However,a little attention has been paid to the spatial association of network spatial phenomena.The objective of this article is to demonstrate the application of the Q statistic,developed for the anal-ysis of the spatial association of qualitative variables,to the detection of spatial association of the net-work spatial phenomena.This paper introduces the Q statistic concept,and defines distance measureby the shortest path.The spatial association of the hotels in Shenzhen city in China are analyzed usingthe Q statistic.A comparative analysis of the Q statistic in Euclidean space and network space wasconducted.The results show the agglomeration effects among hotels from a spatial data mining per-spective.Results also show that the Q statistic is valid for spatial association analysis of network spa-tial phenomena.
