地震灾情位置微博抓取与展示

Capture and Display of Earthquake Disaster Information Based on Geotagged Microblog

探索了一种地震灾情位置微博的抓取与展示方法。通过分析位置微博在地震灾情获取中的作用,建立了位置微博地震灾情抓取框架。基于新浪微博SDK,实现了有效位置微博的抓取;在顾及地震灾情专题属性的基础上,对抓取的微博进行分级。以云南省昭通市鲁甸地震为例,实现了灾情的提取与严重程度的图示化展示。

We explored a method which could capture and display earthquake disaster based on geo-tagged microblog in this paper.By analyzing the effect of the geo-tagged microblog in the earthquake disaster information acquisition,we established a earthquake disaster based on geo-tagged microblog framework.And then,valid geo-tagged microblog capture based on Sina microblog SDK development was achieved.On the basis of earthquake disaster thematic attribute,captured geo-tagged microblogs were graded.Taking Ludian earthquake for example,we achieved the disaster extraction and the cartographic display of the earthquake severity.
