Abstract

The invention provides an information discrimination method and system. The method comprises the steps of based on a web crawler technology, retrieving and collecting webpage information corresponding to hotspot information of a traditional media and a social media, and processing the collected webpage information to obtain traditional and social media data sets marked with categorical data and divided into training set data and test set data; based on the training set data, performing topic modeling to obtain topic and keyword documents, and establishing a topic characteristic set corresponding to traditional media data and a keyword characteristic set corresponding to social media data; and training a classifier by utilizing the topic characteristic set and the keyword characteristic set, and performing classification discrimination on the test set data through the obtained traditional media classifier and social media classifier to obtain traditional media data capable of triggering social media reports and/or social media data capable of triggering traditional media reports. By monitoring a plurality of medias, the trend of public sentiment development can be analyzed and predicted more comprehensively and more quickly.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an information discrimination method and system. Background technique [0002] At present, the method of monitoring network public opinion mainly adopts the automatic identification of new topics from the information flow and continuous tracking of known topics. For example, the TDT (Topic Detection and Tracking) system in the United States, and the TRS public opinion monitoring system of Beijing Tops Corporation. However, the network public opinion monitoring carried out by the above system is only monitored in a single media, and it cannot combine the interactive relationship between the information flow of traditional media and social media to better analyze and predict the development trend of public opinion. [0003] In view of the current large and scattered national conditions in my country, the source of people's access to information does not only depend...
