Problems solved by technology

[0004] The disadvantages of the method for discovering hotspots of network public opinion based on clustering in the above-mentioned prior art are: the method is based on clustering, and the hotspots of network public opinion can only be discovered after a large amount of relevant information appears, which causes the problem that the discovery of hotspots of network public opinion is not timely; Most of the mass information is spam information. This method often judges many spam messages with high frequency as hot public opinion information, which causes the problem of low accuracy in finding hot spots of network public opinion.

Abstract

The embodiment of the invention provides a method and a device for finding network public opinion hotspots based on network article attributes. The method mainly comprises collecting network articles in the way which integrates oriented collection with search engine collection, calculating the weighted value of each network article according to several kinds of parameter information of the network article, judging whether the network articles are the network public opinion hotspots according to the weighted values of the network articles and a preset public opinion hotspot judgment threshold value, and analyzing the attributes of the judged network public opinion hotspots. According to the method and device for finding the network public opinion hotspots based on the network article attributes, the network public opinion hotspots can be found rapidly and timely. The accuracy of finding the network public opinion hotspots is improved by firstly performing pretreatment, such as filtering junk information and de-weighting, on the network articles, and then judging values of the network articles according to several kinds of parameter attributes of the network articles.

Description

technical field [0001] The invention relates to the technical field of network public opinion, in particular to a method and device for discovering network public opinion hotspots based on network article attributes. Background technique [0002] Internet public opinion refers to the Internet public opinion with different views on social issues popular on the Internet. , Predisposed remarks and opinions. [0003] At present, a clustering-based network public opinion hotspot discovery method in the prior art mainly includes: constructing a vector space model through feature extraction of sample webpage texts, using the OPTICS algorithm to obtain webpage hotspot clusters, and classifying webpages according to the feature vectors of the hotspot clusters. Perform secondary clustering to obtain the time evolution model of public opinion and provide decision support for research in related fields. Then, through secondary clustering, the quality of the relevance of public opinion...
