First, the amount of information should be complete. A network opinion monitoring product can monitor the whole network, which requires that in addition to monitoring the remarks of professional media, it should also monitor the remarks of netizens and consumers in social media such as BS, BLOG, microblog, SNS, and so on.
The second is that the amount of information should be accurate. Since online public opinion is monitored based on keywords, it is required that online public opinion monitoring products must be able to make correct judgments on keywords, tolerate valid information to exclude interfering information, and achieve a high accuracy rate. For example, Ant Square Software is a public opinion system that automatically monitors and analyzes big data.
Third, information monitoring must be timely. If negative information can be found in the first time, effective countermeasures can be carried out to weaken the negative information. On the contrary, if the discovery time is not timely, the negative information may sharply fission public opinion crisis, by then the crisis will not be easy to control, the political and business units will also be trapped in the public opinion passive.
