Question restatement:
Under the new information dissemination pattern, how to get rid of the "scream effect" and "echo chamber effect" and get out of the " information cocoon room " is a practical problem that needs to be solved urgently at present, that is, how to design from the top level of information transmission and recommendation algorithm In terms of fairness and the responsibility of the majority of Internet users, it helps the public to have a relatively accurate and clear understanding and judgment of news events and even social reality, and to find a balance between mainstream awareness and personalized information, making the Internet public opinion environment more stable. Be rational and constructive. Please answer the following questions:
1. For certain topics, download relevant data from social media such as WeChat, Weibo, Facebook, and Twitter, quantitatively describe the dissemination process of the topic (or information), and analyze its influencing factors. The data analysis needs to discuss at least two different topics, one of which tends to be the same (neutral consensus), and the other topic tends to be polarized (opinion polarization).
2. Establish a mathematical model to describe the generation mechanism of neutral consensus and opinion polarization, explore the formation mechanism of "screaming effect", "echo chamber effect" and "information cocoon room", and discuss the attractiveness of topics, user activity, Factors such as user psychology, interaction between different users, and platform recommendation algorithms have an impact on the formation of these phenomena.
3. According to the mathematical model established in question 2, formulate strategies to break the "scream effect" and "echo chamber effect" and avoid the "information cocoon".
4. Based on the above data analysis and mathematical model, write a 1-2 page report on how to break the "information cocoon", and put forward corresponding solutions or suggestions for the top-level design of the government, the leadership of the mainstream media, and the responsibility of the majority of Internet users. .
