Abstract

The invention relates to a webpage information extraction method and device based on an http protocol. The method comprises the steps of template generation, webpage address analysis, information extraction, information checking and information storage, wherein in the template generation step, a corresponding page analysis template is customized according to a target page where information is about to be extracted, and a target field and checking rules are predefined in the page analysis template; in the webpage address analysis step, the webpage address of the target page is analyzed to obtain an HTML source file of the target page; in the information extraction step, the HTML source file of the target page is read and analyzed, and page information matched with the target field predefined in the page analysis template is extracted from the HTML source file of the target page; in the information checking step, whether the extracted page information meets requirements is checked according to the predefined checking rules; in the information storage step, the page information subjected to information checking is stored. According to the webpage information extraction method and device, the page information in a network is subjected to effective data filtration, acquisition and collection through the open http protocol, templates are customized according to different target pages, and extraction of customizing information is achieved.

Description

technical field [0001] The invention relates to the field of information crawling and analysis in network technology, in particular to a method and device for extracting webpage information based on the http protocol. Background technique [0002] The Web 2.0 era is an era of information explosion. Massive data information is flooding in all aspects of work and life. Therefore, the demand for data-based analysis and potential value mining is becoming increasingly urgent. However, in reality, because the data owner has very strict control over the data, many valuable data information cannot be easily collected and extracted. In this context, the importance of data is highlighted, but the availability of data is not high, or even limited. Therefore, how to collect, extract and utilize the target data of concern based on the Internet characteristics of the data has become an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved b...
