Embodiment Construction

[0038] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] refer to figure 1 , figure 1 A flow chart of a method for obtaining and classifying earthquake emergency and disaster information provided by an embodiment of the present invention, the method includes:

[0040] S1, grab target network information through data crawler tools.

[0041] Specifically, start the data crawler tool, set the subject words and save the database information; by monitoring the subject words, crawl the web pages with relevant subject words, obtain the network information related to the earthquake, and refresh the interface regularly, if there are new The information is captured into a database.

[0042] A web crawler is a program that automatically grabs web pag...

Abstract

The invention provides an acquisition and classification method and system of earthquake emergency and disaster information. The method comprises the following steps: capturing target network information through data crawler tools; performing word segmentation and part-of-speech tagging on the captured target network information and acquiring text segmentation information; calculating the overallindex value of the target network information based on initial weights of preset key words and the text segmentation information, and matching the corresponding information type with the target network information. The method provided by the invention ensures accuracy of data classification by means of word segmentation of the network information based on characteristics of different types of theearthquake emergency information and text classification based on the weights of the key words. According to the invention, an emergency information index system for public participation is generallyestablished to realize fast collection and acquisition tools of the emergency information, extend the information source for the earthquake emergency and improve timeliness and accuracy of the earthquake disaster emergency service.

Description

technical field [0001] The present invention relates to the field of computer science and technology, more specifically, to a method and system for obtaining and classifying earthquake emergency and disaster information. Background technique [0002] my country is a country with many natural disasters, accident disasters and other emergencies. There are many types of disasters, high frequency of disasters, and serious disaster losses. At the same time, it is also one of the countries with the strongest seismic activity and the worst earthquake disasters in the world. The 2008 Wenchuan Earthquake and the 2013 Lushan Earthquake both caused huge economic losses. The timely and effective command of earthquake emergency is related to the results of disaster relief. [0003] The 7.2-magnitude Hanshin earthquake in Japan in 1995, the 7.8-magnitude earthquake in Izmit, Turkey in 1999, and the 7.9-magnitude earthquake in Gujarat, India in 2001 have a lot to do with the slow respons...
