Abstract

The invention provides a method for immediately tracking random event evolution based on Internet mass information. According to the method, an initial spatial vector of an event is constructed by using basic characteristic elements, in the tracking process, entropy values of frequently-used words of Internet increment information are computed and counted on the basis of the initial spatial vector, the growth and structural change of the initial spatial vector of the event are determined by taking the entropy values as event evolution power, and the stable fission of new event space is realized by the entropy value comparison of an increment information vector and an event critical space vector, so that the identification and tracking of a derivative / secondary event are realized. By the method, the entropy values of the increment information are taken as the power of the event evolution, so that the requirements of work such as tracking, pre-warning / predicting emergency events and random events can be effectively met; and meanwhile, the method is high in topicality, reliability and expandability, and the common phenomenon that the load of computational nodes and a network is heavy in a mass information processing activity is avoided.
