| description | The invention discloses an unsupervised emergency telephone traffic event monitoring and early warning method. The method comprises the following steps: preprocessing an emergency corpus; constructinga text-word feature matrix, adopting a word monitoring method, extracting similar words of each target word through a word vector model, and then judging whether each call hits the target words and the similar words of the target words or not; calculating a feature index and a statistical index of each target word, and extracting the target word with large statistical index fluctuation as a burstword; extracting one or more time periods with the most abnormal characteristic index fluctuation of each burst word to serve as time periods when the emergencies occur; improving event information,enriching keywords of events and calculating telephone traffic and index information of the events and filtering events and outputting emergency telephone traffic event information. The method solvesthe problem of how to monito |
