Space-time clustering method for information acquisition of public security event

Abstract

The invention discloses a space-time clustering method for information acquisition of a public security event. The method comprises the steps of extracting information about the public security event in network text, and conducting clustering processing; then, conducting visualization; analyzing the influence range, development process, possible results and the like of the public event. Through the adoption of the space-time clustering method for the information acquisition of the public security event, after the public security event occurs, in combination with an event type and event keywords, the effective information about the event can be quickly extracted from social websites, and therefore through a space-time clustering algorithm and a map visualization system, the development process and evolution rules of the event are obtained efficiently, the determination of a solving decision for the public event is facilitated, and the solving efficiency of the public event is improved.

Description

technical field [0001] The invention belongs to the field of application of crowd-sourced network data to management, monitoring, early warning and emergency response of public safety events, and in particular relates to a time-space clustering method for information acquisition of public safety events. Background technique [0002] With the rapid development of the national economy and the continuous advancement of national urbanization, more and more people are concentrated in cities. The rapid growth of urban population data has caused certain troubles for urban public management. At present, the management of various public events in cities is mainly in the charge of government departments, including urban management departments, police agencies, fire agencies, medical departments, disaster prevention and reduction centers, disaster response command centers, etc. (Zhu Wuxiong, 2010; Xu Zhisheng et al., 2005; ), these government agencies provide an effective security bar...
