Abstract

The invention provides a screening method and device of emergency data. The screening method mainly comprises the steps of building a denoising general list, a combined-word list and a reverse-word list; according to one or more of the denoising general list, the combined-word list and the reverse-word list, screening the collected data related to an emergency. Through natural language analysis, the screening method provides a basis for building an emergency keyword list. In order to ensure the data accuracy, the emergency data is screened by means of multiple word lists. Centering on the comprehensiveness and accuracy of the data, the precision ratio and recall ratio are used for conducting quantitative evaluation to the performances of all the word lists, and a basis is provided for update of the word lists.

Description

technical field [0001] The invention relates to the application field of computer technology, in particular to a screening method and device for emergency event data. Background technique [0002] At present, the world has entered a period of high incidence of emergencies, and various emergencies occur frequently, posing a huge threat to people's lives and property safety. In the face of emergencies, quick and effective emergency decision-making plays a vital role in reducing losses. The experience and lessons of historical emergencies have important reference value for the formulation of emergency decisions. Therefore, it is necessary to collect and study the data of emergencies. In addition, the research and analysis of historical emergencies is also of great significance to the prevention and prediction of emergencies. [0003] However, with the continuous emergence of online information publishing methods such as Weibo and social networks, the types and scale of data a...
