The Internet platform is one of the most important fields for information dissemination and public opinion in today's society。It uses powerful data collection、Calculation Power，undertake the distribution and communication function of network information，Relying on the algorithm model to screen out information that meets user interests and preferences，and then push it to users accurately。This algorithm recommendation service，Both are conducive to user information acquisition and dissemination，It will also lead to the user’s "information cocoon room effect" and polarization of opinions，and guide public opinion to the mainstream media constitute a certain challenge。

What is the "information cocoon room effect"? American scholar Cass Sunstein (in the book "Utopia"，defines it as "we only listen to what we choose and the communication field of what we are happy"。That is to say，Users usually only pay attention to the content they are interested in，It is like being trapped in a cocoon for a long time，isolated from other information。

In the Internet era，To compete for users and traffic，Some media and algorithm recommendation services only actively push the user's favorite information，The breadth of the user obtaining information over time is seriously limited。At the same time，The algorithm is judged based on the user's occasional browsing or click，Continuous push related content，It may bet365 best casino games also lead to solidification of users' interest，Falling into "Information Cocoon Room"。As the "user portrait" in the algorithm is becoming more and more accurate，The content of the content of algorithm production and communication is getting higher and higher with the audience，Other content is easily excluded from the scope of the audience。

"Information Cocoon Room Effect" is not only a limit on individuals，will also lead to the group polarization of the entire network of public opinion。On the Internet platform，Users can freely choose content interested、Follow the person you like、Add to the online community interested in。Under the boom of the algorithm recommendation technology，People can easily get the same information，Find a like -minded person。Case Santan mentioned the "Echo Room" when defining the "Information Cocoon Room"，"It is easy to get various views through the Internet，or even hundreds of thousands、Common collaboration of millions of people，Risks and promises are derived from this。Every day，People with similar ideas can and return themselves into the echo room they designed，Make extreme errors、Excessive self -confidence and extremism that is unreasonable "。The information obtained by people is their own voice that reflected through the "Echo Room"。

This "echo room effect" has exacerbated the perspective of the inside of the group，Repeated discussions make the views becoming more and more extreme。According to the "Silent Spiral" theory of German Communication Scholar Elizabeth Normann，Once the user thinks that Bet365 lotto review a certain value orientation is widely welcome，Then the sound that is consistent will rise，The sound of opposite will fall into silence。Algorithm Recommended Households to produce the impression that "many people have this value orientation"，Lead of distortion of online public opinion field。If there are a large number of audiences have conceptual polarization problems，The potential resistance of condensing social consensus will increase，Various thoughts and concepts of various ideas will become more serious。

Algorithm recommendation service not only affects the information acquisition and opinion formation of individuals and groups，It also affects the fairness and openness of public opinion，Leading online public opinion guidance is facing difficulties。The algorithm is recommended according to the user's historical behavior and interest，The emphasis on user preference rather than news value，It has encouraged the living environment of false information。In the era of traffic，Fake information is usually more attractive and controversial，It is easy to cause users to click and share。

Algorithm recommendations are also easily abused to manipulate public opinion，It may dissolve the party and the government's guidance of public opinion on the Internet。Some political forces、Commercial institutions and individuals can use algorithms to recommend promoting their agenda，You can influence the public through customized content and information to push the public，Even implementing political manipulation。The fairness and independence of the mainstream online public opinion pose a threat，Bet365 app download Actions that may cause manipulation information，Not based on objective facts and public interests。

other，The operating mechanism recommended by the algorithm is usually "black box"，Lack of transparency。It is difficult for users to understand why they see certain information，The logic and algorithm behind the recommendation cannot be tracked，It is difficult to understand your information acquisition process。Insufficient transparency may cause users to doubt the source of information，It also reduces the influence of mainstream public opinion guidance。

Why is algorithm recommendation difficult to supervise? Mainly due to the complexity of its technology，Operating mechanism is opaque，It is difficult to conduct effective review and evaluation。Algorithm recommendation service providers are often reluctant to disclose the design principle of the algorithm、Data source、Model Construction、Project verification and other information，It makes it difficult for the regulatory authorities and the public to understand and master the real operation of the algorithm，It is difficult to find and correct the problems and defects of the existing algorithm。

　　The media dominant position in the reinforcement algorithm recommendation 

For public opinion guidance，Algorithm recommendation is "Double Blade Sword"。So，Researcher Zhang Taofu proposed: "You should make full use of the algorithm technical advantage，Large range、Precision grasp the needs of the audience，In particular, it is necessary to accurately inspect the value preference of users，Some targeted accurate communication，to achieve effective arrival of mainstream bet365 Play online games value。"to achieve this goal，can start from the following aspect。

First，Strengthening the dominant position of mainstream media in the recommendation of algorithms，Give play to the guidance of public opinion。Mainstream media must strengthen the construction of new media expression capabilities，Establish a special agency to develop algorithm models that meet their own value orientation，Strengthen the supervision of the algorithm，Prevent excessive commercial tendencies。To increase the output of positive information，Rich and high -quality energy content library，Meeting the requirements of the algorithm。Innovation positive propaganda form，Improve the spread of mainstream media on the new media platform，Give play to the positive guidance。

Second，A perfect algorithm management regulations，Clarify the main responsibility and behavioral specifications。Pressing the main responsibility of the platform，Strengthen the development of algorithms、Application、Organic process management，Prevent algorithms from deviating from the core values ​​of socialism。Strengthen the implementation effect of the "Recommended Management Regulations on Internet Information Service Algorithms"，Timely accountability for a platform that failed to fulfill the main responsibility、Supervise rectification，Ensuring fair transactions and consumer rights。

third，Innovation algorithm supervision method，Realize dynamic monitoring and rapid response。Use "Buried Point" technology，Implement the entire process of content dissemination，Supplemented by manual bet365 Play online games review to improve monitoring accuracy。Establish an emergency response mechanism for public opinion，Quick intervention for emergencies，Stable and guiding public opinion。Optimization of report rewards and processing mechanisms，Forms a joint supervision force。

Fourth，Break "Information Cocoon Room"，Improve algorithm guidance effect。The algorithm platform should set a variety of recommendation functions，Guide users to expose more wide range of content，Improve information acceptability。Properly push information on different views on the homepage or key page，Taking care of user knowledge structure diversity。Establish a user label system，Differential user type，Avoid labeling thinking。A comprehensive algorithm responsibility mechanism，Accept social supervision，Improve recommendation transparency and fairness。

Fifth，The ability to improve the public recognition algorithm，Stimulate social supervision forces。Strengthening Education of Algorithm Knowledge，Make the public clear the algorithm operation mechanism。Guide the public to cultivate multiple information requirements，Improve the authenticity of identification information。At the same time，Encourage users to actively participate in and supervise the operation and development of the recommendation service services，Reporting or complaining algorithm Recommended services in time or adverse effects，and feedback or make suggestions to relevant departments and institutions，Maintain the health and order of public opinion on the Internet。
