Spatio-temporal data dynamic evolution diagram generation method for public security events and dynamic evolution system thereof

Abstract

The invention relates to a spatio-temporal data dynamic evolution diagram generation method for public security events and a dynamic evolution system thereof. Compared with the prior art, the defect that data cannot be visually displayed through theoretical analysis of public security event data is overcome. The method comprises the following steps: mining spatio-temporal data; preprocessing the public security spatio-temporal object data; setting a public security event spatio-temporal sequence; and constructing a spatio-temporal data dynamic evolution diagram. According to the method, a bigdata semantic analysis technology and a grading spatio-temporal expression method based on spatio-temporal objects are utilized, grading construction is carried out on the spatio-temporal process of the public security event, a spatio-temporal data dynamic demonstration diagram is generated through a graph theory, and therefore the spatio-temporal evolution relation between the public security event objects is visually expressed.

Description

technical field [0001] The invention relates to the technical field of data semantic analysis, in particular to a method for generating a dynamic evolution diagram of spatio-temporal data oriented to public safety events and a dynamic evolution system thereof. Background technique [0002] Public security incidents refer to incidents that affect the safety of people's lives and property and national security and stability, including natural disasters, accident disasters, public health emergencies, and social security. Although the occurrence of public security incidents has strong randomness and contingency, from the perspective of data analysis, the basic laws and characteristics of their occurrence still have a strong temporal and spatial correlation. [0003] With the development and improvement of information technology and the continuous maturity of Internet of Things devices, public security data has shown explosive growth. Explore the time-varying laws and spatio-tem...
