National leaders often communicate with netizens online during their busy schedules. Through the Internet, they can understand people's feelings, gather people's wisdom and listen to various opinions and suggestions of netizens. Grassroots cadres should directly listen to the opinions of the masses, understand their voices, solve their difficulties, and do practical things for the masses, which has become a new embodiment of the * * * production party's adherence to the mass line. At present, both the central government and the State Council have set up special public opinion agencies to be on duty 24 hours a day, and provide them for leaders' reference in the form of "online public opinion". Party and state leaders have many instructions to online public opinion every year. At the same time, governments at all levels are setting up network public opinion monitoring, analysis and response teams, establishing relevant duty systems and emergency response mechanisms, and a considerable number of them are on duty 24 hours a day, sending special personnel to monitor designated news websites and forums. In addition, many news organizations, including the official media, are slowly establishing special public opinion analysis, judgment, evaluation and release mechanisms.
The function of public opinion detection and monitoring system Fundamentally speaking, network public opinion monitoring requires real-time, comprehensive and accurate. Duoruike public opinion data analysis station can meet the three major elements of the system public opinion information service market, namely, real-time: the earlier the public opinion is obtained, the greater the space left for response and disposal, while the development of online public opinion is often explosive, and the opportunity is fleeting. Once the best opportunity is missed, it will be regretted; Comprehensiveness: Internet public opinion is a little easier to attack, not as good as the rest, with a large amount of information, and it is easy to ignore many important information; Accuracy: under the condition of massive information, how to accurately grasp the core of the problem and not be trapped by interference is the key to making a correct judgment.
At present, public opinion monitoring has a lot to improve. First of all, manual monitoring has natural limitations. By arranging fixed personnel to be on duty 24 hours a day, constantly browsing target sites and searching for target keywords, it is the most direct and primary public opinion monitoring method in the absence of automation system. Due to the limitation of everyone's subjective thoughts, there will always be blind spots in manual monitoring, and there will always be places that are unimportant but proved to be serious afterwards. Manual monitoring cannot detect the changes of some websites or some remote web pages; At the same time, people are not machines, and repeated monitoring for a long time will easily lead to fatigue, and often the judged public opinion will be missed if you are not careful. These will fluctuate greatly in real-time and accuracy.
Second, over-reliance on search engines. People often think that only search engines have the ability to find a needle in the ocean of online public opinion. However, search engines still have many limitations. Except that the search results are greatly influenced by keywords, the results returned by search engines often come from websites that are not subject to any access restrictions, while websites that need to log in, such as forums, are completely excluded. However, it is precisely these websites that provide interactive functions that netizens express their opinions the most. Moreover, the web crawler of the search engine has a certain time delay, so it can't search for the latest network updates in real time. So the search engine can't provide us with the whole picture of the problem, because it only pays attention to keywords and doesn't pay attention to the problem, so it can't be comprehensive; Search engines can't get the results we want in the first time, because not only its content is not updated quickly enough, but also it can't provide timely services, so it can't be timely; Search engines can only return another massive result in a massive web page, and it is in a chaotic form. It knows nothing about what we care about, so the result it gives is what everyone cares about, not what I care about, so it is not accurate. It can be seen that we can't rely entirely on search engines to monitor online public opinion, and we need to propose new technical means to learn online public opinion and track it.
Therefore, in order to ensure the real-time, comprehensiveness and accuracy of public opinion monitoring, the most reliable way is to use an automated public opinion monitoring system, rely on the software system to eliminate the shortcomings of manual methods, rely on the software system to monitor target sites and the whole network at fixed points, track and analyze the development track of various public opinion topics, and automatically sort out and generate daily/weekly reports, thus organically combining public opinion with the daily work and business of the government.
The main function is: (1) The network information collection system collects news, forums, blogs, comments and other public opinion information from the Internet and stores it in the collected big data cloud library. (2) The public opinion analysis engine system is responsible for cleaning, intelligent judgment, automatic clustering and processing the collected information, and the analysis results are stored in the public opinion achievement database. The public opinion analysis engine relies on intelligent analysis technology and public opinion knowledge base. (3) The public opinion service platform publishes the processed public opinion data from the public opinion database to the Web interface and displays it. (4) Browse the public opinion information through the public opinion service platform, and the system will automatically generate a briefing and other functions to complete the public opinion deep processing and daily public opinion monitoring work.
