Douyin Vice President Li Liang Explains Recommendation Algorithm: Breaking Information Bubbles and Protecting the Content Ecosystem

Recently, Douyin Group Vice President Li Liang engaged in an in-depth discussion with the media regarding the practices and considerations behind Douyin's recommendation algorithm, covering aspects such as algorithm value and governance. He pointed out that in the age of information explosion, recommendation algorithms are crucial for improving information acquisition efficiency and have become an indispensable part of people's daily lives.

Li Liang stated that recommendation algorithms effectively reduce the cost of information acquisition for users, preventing them from wasting time and energy sifting through massive amounts of information. He used the example of Shi Tiesheng's work "I and the Temple of Heaven" regaining popularity on the Douyin platform to illustrate the immense benefits of accurately matching high-quality content with target user groups. This not only boosted book sales but also promoted the dissemination and inheritance of cultural works, enabling more young people to access and understand classic literary works.

Regarding the differences between Douyin's recommendation algorithm and those of other platforms, Li Liang emphasized that from an algorithmic principle perspective, there are no fundamental differences. The key lies in the platform's objectives. Douyin's North Star metric is long-term user retention; therefore, its algorithm design focuses on satisfying users' long-term interests and needs, striving to provide a consistently high-quality content experience to improve user stickiness and extend usage time.

Addressing the consideration of more diversified algorithm models, Li Liang acknowledged that in the current context of information overload, simply arranging information chronologically is no longer feasible. To this end, Douyin's algorithm incorporates an interest exploration mechanism to proactively help users discover diverse content and break down information homogeneity. Simultaneously, Douyin provides users with the option to turn off personalized recommendations, respecting users' choices regarding information acquisition methods and catering to diverse needs.

Regarding the public's widespread concern about information bubbles, Li Liang stated that information bubbles are not directly caused by the algorithm itself. All information dissemination channels have certain limitations, and most people's information acquisition methods are diverse and comprehensive. From a business logic perspective, platforms have no incentive to create information bubbles; instead, they have a greater incentive to break them, providing users with a broader information horizon. To achieve this goal, Douyin has implemented a series of measures: introducing search, social sharing, and trending hot lists as diverse content distribution mechanisms; strengthening social recommendations; deliberately promoting diversified recommendations; and incorporating an interest exploration mechanism into the algorithm to provide users with richer and more comprehensive content choices.

Regarding algorithm optimization and governance, Li Liang introduced Douyin's specific strategies. Douyin's recommendation mechanism considers various signals, including user comments, likes, dislikes, and reports, to reduce the spread of unfriendly and controversial content and maintain a healthy platform ecosystem. To address issues such as exploiting algorithm loopholes to gain traffic and fostering gray and black industries, Douyin will continue to increase its efforts in combating and governing these issues, using standardized and scalable processing capabilities to ensure the timely and effective handling of misinformation. Furthermore, Douyin pays particular attention to misinformation about companies related to sensitive public opinion issues, accelerating processing speed and establishing inter-departmental communication mechanisms to reduce information transmission bias. They also cultivate employees who are experts in specific corporate rumors to improve judgment and resolution efficiency.

Li Liang emphasized that ecosystem governance is crucial for the healthy development of the platform. Douyin will continue to optimize algorithm governance to provide a higher-quality and more diverse content experience, creating a positive, healthy, and harmonious online environment for users. He believes that the ultimate goal of the algorithm is to serve users, providing them with more convenient and efficient channels to access information, while also bearing the responsibility of maintaining the platform ecosystem and combating illegal activities. Douyin will continue to invest resources in continuously improving its algorithm mechanisms to provide users with safer and more reliable information services. This not only reflects Douyin's social responsibility but also provides valuable reference for other platforms in algorithm governance.

Douyin's algorithm optimization and governance work is not only reflected in the technical aspects but also emphasizes user experience and social responsibility. Through various measures, Douyin strives to balance personalized recommendations with information diversification, effectively preventing the information bubble effect while enhancing user experience and maintaining a healthy platform ecosystem. This reflects Douyin's strategic consideration for long-term development and its commitment to social responsibility.

In the age of information explosion, how to effectively utilize algorithm technology to meet users' personalized needs while avoiding the information bubble effect is a common challenge facing all internet platforms. Douyin's practical experience provides valuable reference for other platforms and offers new ideas for exploring more comprehensive algorithm governance models. Douyin's efforts also demonstrate that technology is not neutral, and platforms need to assume corresponding social responsibilities in the process of technology application, actively exploring more responsible and sustainable technological development paths.

The fairness, transparency, and societal impact of algorithms are attracting increasing public attention. Douyin's exploration and practice in algorithm governance have not only enhanced its platform governance capabilities but have also set a good example for the entire internet industry. In the future, Douyin will continue to uphold the user-centric philosophy, continuously optimize algorithm mechanisms, and contribute to creating a healthier and more positive online environment. Douyin will also actively cooperate with other platforms and regulatory agencies to explore more effective algorithm governance solutions and contribute to building a more harmonious digital society.

Through continuous improvement of algorithm mechanisms and optimization of the content ecosystem, Douyin strives to provide personalized information services while avoiding the risks of information bubbles, thereby enhancing the overall quality and experience of users' information acquisition. This requires not only continuous technological innovation but also a deep understanding of user needs and the assumption of corresponding social responsibilities by the platform.

Douyin's practice shows that effective algorithm governance requires the joint efforts of multiple parties. The platform itself needs to continuously improve technical means and enhance regulatory capabilities; users need to improve their ability to discern information and avoid being misled by false information; and regulatory agencies need to improve relevant regulations to provide institutional guarantees for algorithm governance. Only through the joint efforts of multiple parties can a healthier, safer, and more orderly online environment be built. Douyin's exploration and practice provide valuable reference for achieving this goal.

Li Liang's explanation of Douyin's algorithm in the interview also provides valuable experience and reference for other internet platforms. While pursuing user experience and commercial interests, how to balance the algorithm's personalized recommendations with social responsibility is an issue that all internet platforms need to seriously consider and address. Douyin's exploration and practice provide new ideas and directions for resolving this issue.

Through continuous efforts and improvements, Douyin is committed to creating a safer, more reliable, and healthier information environment for users and contributing to building a more harmonious digital society. This is not only Douyin's responsibility but also the shared mission of all internet platforms. In the future, more platforms are expected to join the ranks of algorithm governance to jointly promote the healthy development of the internet industry.
