Public security event-based mobile cloud data mining method

Abstract

The invention discloses a public security event-based mobile cloud data mining method. The method comprises the steps of S1: selecting a mobile network cloud public social application platform, namely, according to a usage amount of a user, selecting the mobile network cloud public social application platform; S2: massively mining public security hot events, setting a time point based on data of the selected mobile network cloud public social application platform, and extracting data of three dimensions of a forwarding amount (T), a concerning amount (G) and a rating amount (C) of public security event information before the time point; S3: calculating popularity attenuation factors of the public security hot events, and by reference to and based on a Newton cooling law, generating the popularity attenuation factors of the three dimensions of each time period of the events; S4: cleaning the public security hot events, performing sigma 1, sigma 2 and sigma 3 setting on investigated weights of the data of the three dimensions, and obtaining current popularity factors of the event information; and S5: fusing public security hot event mining data, constructing or updating a database bythe events with the popularity factors higher than a threshold, and additionally attaching event keyword fields in a data storage process to serve as data mining results for the user to use. The public security event-based mobile cloud event hot data information mining is realized; an interface can be provided for a public security management related application; and the security event identification acuity is improved.
