And S12, analyzing the public opinion information based on a public opinion data research and judgment algorithm preset in the intelligent contract of the block chain and forming a public opinion report.
The public opinion data studying and judging algorithm is mainly used for further analyzing the public opinion information written into the first block chain database. The public opinion analysis mainly comprises hotspot analysis, negative information analysis and trend analysis. The negative information analysis comprises positive and negative semantic recognition of the public opinion information, and writing a negative information analysis result in a positive and negative semantic recognition corresponding result into a public opinion report; the trend analysis mainly includes clustering and classifying documents through the frequency and the similarity of keywords in the data set, and performing hotspot or sensitive topic analysis, tendency analysis and trend analysis according to clustering and classifying results.
And S13, writing the public opinion report into a second blockchain database through a blockchain network, and supervising and controlling the public opinion.
And summarizing the results of the negative information analysis, the hotspot analysis and the trend analysis to form a public opinion report, writing the public opinion report into the block chain network and storing the public opinion report into the second block chain database, so that the safety and the non-falsification of the public opinion analysis result are ensured.
