Abstract

The invention relates to a text big data based digitized emergency management case library establishment method and device. The method comprises the steps that data is acquired at regular intervals, and the acquired data is preprocessed to obtain Chinese text segmentation results; based on the Chinese text segmentation results, identification of emergency related data is achieved through data cleaning according to a set emergency field keyword vocabulary to obtain emergency classification results; based on the emergency classification results, identification and tracking of special emergencies are performed; structuralized information description is conducted on special data about emergency identification and tracking by utilizing an information extraction method to obtain various emergency case libraries. The emergency related data can be automatically acquired, and secondary emergency classification can be automatically achieved. The special emergency identification and tracking can be automatically performed, and analysis and information extraction conducted on designated emergency related data are represented through cases to form emergency case representation.

Description

technical field [0001] The invention relates to the field of computer technology applications, in particular to a method and device for constructing a digitized emergency management case library based on textual big data. Background technique [0002] The emergency response process can be divided into four stages: prevention and emergency preparation, monitoring and early warning, emergency response and rescue, and post-event recovery and reconstruction. However, due to the explosive and complex characteristics of emergencies, it is difficult to achieve effective and comprehensive prevention and early warning. Therefore, only by making timely and effective emergency response decisions in the process of emergency response and rescue can the development of the incident be controlled. situation. Considering the limited pertinence and operability of emergency plans, historical emergencies can be sorted out to form typical cases, and then emergency personnel can learn from typic...
