Research On The Phenomenon Of "Information Cocoon Room" Based On Personalized Recommendation Of Tiktok Short Videos

With the era of information dissemination,network intelligence technology has achieved rapid upgrading,information dissemination methods and channels continue to increase,society presents the phenomenon of "information overload",people can not effectively integrate,organize and internalize the information required by individuals,so personalized recommendation technology came into being.The TikTok short video platform uses this technology to accurately locate the field of user preference information and record the relevant data generated by users when using it,so as to accurately portray the user’s image and achieve the purpose of personalized and accurate delivery.This greatly improves the efficiency of users in obtaining the information they need,while helping media platforms attract and retain a large number of users in the long term.However,in the long run,the source of homogeneous information is continuously pushed,and heterogeneous information cannot be presented to users due to layers of technical filtering,so that the original concept between individuals and groups is constantly strengthened,and even heterogeneous information is excluded,thus forming a closed "information cocoon".Based on Keith R.Sunstein’s research theory of "information cocoon" and other related theories,the homogeneity of the concept of "information cocoon" is decomposed into three dimensions of choice,content and group,and the concept of "information cocoon" is divided from the perspectives of horizontal and vertical,and the operation process of TikTok short video personalized recommendation system is summarized,and the main manifestations of "information cocoon" in the platform are summarized.On the basis of this theory,the research method of case analysis is used,and the description and analysis of the adverse impact cases of "information cocoon" under TikTok’s personalized recommendation are used as the background,and the internal motivation and environmental impact factors of building "cocoon room" are analyzed from the social and individual perspectives.According to the formation factors,the negative effects of the "information cocoon" phenomenon on individual cognition,behavior,mentality,platform reputation and social stickiness are summarized from three different perspectives: user,platform and society,and the corresponding "cocoon" breaking suggestions are given.It is intended to achieve the purpose of warning individuals of their perception of the "information cocoon",cultivating personal media literacy and information aggregation awareness;At the same time,it is suggested that the platform combine "personalization" and "commonality" according to technical means,and promote social promotion of literacy education.And believes that the joint efforts of the three parties are expected to break through the "information cocoon".
