Abstract

The invention relates to a method for constructing and updating a mountain torrent disaster database based on web crawler and semantic recognition. It uses web crawler technology and semantic analysis method to grab information web pages and extract key information of mountain torrent disasters, and packs the extracted information into The standard related information is stored in the mountain torrent disaster database, and it is updated and supplemented in real time. This method makes full use of network information resources, supplements and collates the flash flood information at the site, describes and analyzes the occurrence and development process of flood events more comprehensively and accurately, and solves the problem that the current flash flood disaster network data resources are large in number, variety, and source, and it is difficult to accurately The technical problem of efficiently extracting useful data information provides a useful method for the rapid construction and update of the mountain torrent disaster database.

Description

technical field [0001] The invention belongs to the technical field of mountain torrent information collection and processing and the field of information technology using computer software to collect and process network information, in particular to a method for building and updating a mountain torrent disaster database based on web crawlers and semantic recognition, mainly used for mountain torrent disaster information Extraction and supplementary update of mountain torrent disaster information. Background technique [0002] In recent years, with the rapid development of the network, the Internet has become the carrier of a large amount of information, and searching for the required data from the Internet has become a new hot research field. It is estimated that by 2020, the total amount of global data will exceed 4 trillion GB. Using data analysis and other technical means to explore the hidden relationship rules in data is a common method in all walks of life. However,...
