The invention relates to an emergency early warning method and device based on meta-knowledge and an electronic device. The method comprises the steps that a target keyword in target text data and the time sequence popularity of a first event in a first time period are obtained, the target text data are text data describing the first event, and the time sequence popularity of the first event in the first time period is obtained; the target keyword is a keyword used for describing feature information of the first event in the target text data; meta-knowledge of the first event is determined according to the target keyword, and the meta-knowledge is used for indicating target event features of the first event; according to the meta-knowledge and the time sequence popularity in the first time period, the target popularity of the first event in the second time period is determined, and the termination time of the first time period is earlier than the starting time of the second time period; and the occurrence probability of the second event is determined in the second time period according to the meta-knowledge and the target popularity. According to the invention, the technical problem of low efficiency of event early warning is solved.
Description
technical field [0001] The present application relates to the field of computers, in particular to a meta-knowledge-based emergency early warning method, device and electronic device. Background technique [0002] With the rapid development of social networks, it directly leads to profound changes in traditional paper media, which greatly improves the efficiency and enthusiasm of people in obtaining, paying attention to and participating in social events. As a result, more and more people use new media to create and distribute massive amounts of information, promoting information diversification, and making it easier for people to filter the information they need. In this diversified information mode, information will be disseminated quickly, so some Uncontrollable dissemination of information. Such uncontrollable events are defined as network emergencies. Such network emergencies may cause chain reaction events. In order to avoid chain reaction events caused by network emer...
