Embodiment Construction

[0037] The specific embodiment of the present invention is as figure 1 As shown, the specific steps are described as follows.

[0038] 1. Web page information crawling

[0039] Use Internet information crawler software (such as Heritrix, Nutch, etc.) to crawl the webpage information in the information source. During the crawling process, based on technologies such as limited range crawling and vertical crawling, the required Internet webpage information is obtained as much as possible and stored. .

[0040] 2. Spam filtering

[0041]With the development of the Internet, the number of web pages and the amount of content on the Internet are increasing. But at the same time, there are more and more spam information in the webpage. In order to ensure the accuracy of subsequent information processing, it is necessary to filter the spam information. The spam filtering link can be divided into two aspects: Web spam page filtering and spam opinion filtering in user-generated conte...

Abstract

The invention discloses an internet open information-based event occurrence risk prediction and early-warning method. The method comprises the following steps: (1), carrying out spam filtering on webpage information; (2), parsing words expressing location in the filtered webpage information to obtain a place name word; and carrying out processing on the parsed webpage information based on an established information body and classifying the webpage information into a matching region; (3), filtering the webpage information so as to obtain webpage information related to food safety, and carrying out processing on the filtered webpage information by using a regression analysis model and determining an object type related to each piece of webpage information; (4), determining webpage information sets of events of a set region and a set object and establishing event feature parameters and calculating parameter values regularly, and carrying out early warning on an event whose feature parameter exceeds a set threshold value; and (5), on the basis of a matrix analysis and a regression prediction model, carrying out different early warning on a risk of set event occurrence at a target region. According to the invention, the efficiency of risk early warning is improved.

Description

technical field [0001] The invention belongs to the field of information technology, and particularly relates to a method for performing specific processing on crawled Internet information, and then predicting and early warning the risk of a specific event in a specific area, which is mainly used in food safety information monitoring, risk early warning, etc. Emergency response to unconventional emergencies. Background technique [0002] In recent years, food safety incidents such as poisonous capsules, twice-cooked oil, clenbuterol, dyed steamed buns, plasticizers, and poisonous cucumbers have occurred frequently, which have not only caused extremely bad social impacts, but also brought a lot of economic losses. In order to avoid or minimize the harm caused by these food safety incidents, event-based risk early warning technology has begun to receive great attention. For event-based risk early warning, it is necessary to discover information about these events in advance. ...
