Information monitoring and analyzing system

Abstract

The invention provides an information monitoring and analyzing system. The information monitoring and analyzing system comprises a data preprocessing module and a semantic orientation identification module, wherein the data preprocessing module is used for screening web texts by utilizing positive and negative emotion symbols and extracting a candidate-word set from the screened web texts; the semantic orientation identification module is used for establishing a network of lexical semantic trend values for the candidate-word set obtained from data preprocessing, selecting emotion symbols of which the word frequency in the candidate-word set in an emotion set is higher than the preset value as candidate words, expanding low-frequency words by utilizing a synonym word group, extracting emotion words, and calculating the semantic orientation strength by utilizing the candidate words and the network of lexical semantic trend values so as to realize the semantic orientation recognition of words. Through the adoption of the information monitoring and analyzing system provided by the invention, the multi-dimensional monitoring is performed on the public sentiment of the Internet, and the sensitive information is effectively acquired and analyzed, so that the precision ratio and the recall ratio are increased.

Description

technical field [0001] The invention relates to data collection and analysis, in particular to an information monitoring and analysis system. Background technique [0002] Compared with the original traditional Internet form, today's Internet form has undergone tremendous changes. With the continuous introduction of new portable mobile devices, people have broken away from the traditional wired Internet mode of old-fashioned desktop computers. The functions of mobile devices are emerging in an endless stream. is the most basic function. People can take photos of what is happening around them through mobile devices, and upload them directly to the Internet. The speed of information dissemination is extremely fast. If there is no reasonable monitoring, illegal information may appear, misleading the public's judgment, and leading to the wrong direction of public opinion. direction. In public opinion detection, the data collection function is particularly important. After all ...
