Trend analysis of public opinion based on Markov chain
摘要
Abstract
Public opinion often has a hidden trend behind its characteristics shown online.A Markov chain based public opin ion analysis method is proposed.In this method, indicator data of public opinion are collected to get the value of time series for the trend.Then the trend changes and the state spaces are analyzed, and the state transition matrix for the final trend is built.Experiments demonstrate that this method can effectively predict the trend of focus public opinion, and be of signifi cance in guiding and controlling the public opinion.关键词
