Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] In order to effectively determine news influence, we make full use of some characteristics of news web pages. We found the reposting or similar webpages of the news webpage through weight judgment processing, then extracted the reprinting information and reply information, and calculated the reprinting rate and replying rate of the news, and finally used the CIIS value of the news source website as the final scaling factor, Use the formula to calculate the influence of the news. by figure 1 For example:

[0040] The structure of the system of the present invention comprises:

[0041] Web page content weight judgment module 1: The MD5 method is used to judge the weight of the entire document. If the documents are completely consistent, the reprint relationship between the web pages is directly determined. If the documents are not completely consiste...

Abstract

The invention provides a tool for quantitatively analyzing internet news influence based on information retrieval and a method thereof. The tool comprises a webpage content duplication determine module, a relevant information extracting module, a news reprint rate calculating module, a newsletter source website influence determine module, a news recovery rate calculating module and a news influence calculating module, wherein, the webpage content duplication determine module determines whether a webpage is an approximate webpage or not; the relevant information extracting module extracts relevant information in the webpage; the news reprint rate calculating module reprints a website technorati authority value; a news source website and the news reprint rate are found out; the newsletter source website influence determine module determines the popularity index of the news source website to acquire a newsletter source website influence factor; the news response rate calculating module determines a network news recovery rate; and the news influence calculating module calculates the news influence value. The method comprises the following steps: determining that whether the webpage is the approximate webpage or not; extracting news webpage reprint information and recovery information; calculating the news reprint rate; calculating the recovery rate of the news; calculating the technorati authority of the news source website; calculating the influence factor of the news source website; and calculating the news influence. The quantitative calculating result is combined with qualitative analysis of a user to help the user determine the news influence.

Description

technical field [0001] The invention relates to the field of network information content security, in particular to a method for realizing network news influence analysis in the field of network information content security. Background technique [0002] As an emerging way of information dissemination, online news will have a great impact on social stability. The rise of news and public opinion supervision began with the "Fourth Power Theory" created by US Justice Stewart. The so-called "fourth power" refers to news and public opinion. In fact, it is not state power, but it has become more and more important as the news media plays an increasingly important role in social political, economic, and cultural life, and exerts an important influence. Therefore, it is of great significance to determine the influence of news to grasp the trend of public opinion, so as to determine the impact of news on social security. [0003] Prior to this, the analysis of online news was main...
