A network public opinion early warning monitoring method based on space-time scanning

Abstract

The invention relates to a network public opinion early warning monitoring method based on space-time scanning, belonging to the technical field of public opinion early warning and monitoring. Obtainthe ID of each network account; Each network account ID is used as a separate monitoring point, and the network account ID information is stored in a database; Receiving and sending data of each network account is counted by time node. The distance of data relationship between accounts is confirmed by the amount of data sent between accounts; Generate global data matrix statistically; Generating adistance matrix between the accounts according to the account information and the amount of data counted by the time node; Control parameters to determine the scanning range; The logarithm generalized likelihood ratio in the scanning area is calculated and the data is stored in the database for each time. Judging whether the scanning is completed, continuing the scanning if the scanning is not completed, and processing and analyzing all the spatio-temporal scanning data if the scanning is completed; Descending the order of all the spatio-temporal scanning data, analyzing the sorted data information to obtain the suspected outbreak of network accounts and associated accounts.
