Naver (035420.KS) announced Wednesday that it has completed the upgrade of its malicious comment detection system, "AI Cleanbot 3.0." The upgrade intensively blocks comments posted on Naver that promote disregard for life in connection with suicide, death or bodily harm, as well as hateful comments directed at victims of incidents and accidents and their bereaved families.
The "AI Cleanbot 3.0" model is characterized by enhanced malicious comment detection capabilities combined with article context. It has undergone continuous optimization to detect malicious comments by comprehensively analyzing not only the content of news comments but also article titles and body text.
"AI Cleanbot," which Naver introduced in 2019 as the industry's first such system, has expanded its detection scope and accuracy to respond to rapidly changing neologisms and hateful expressions, alongside broader technical and policy efforts across its comment service.
Moving beyond the initial level of automatically detecting profanity and vulgar language based on malicious keywords, Naver expanded the criteria for judging malicious comments to "sentence context" in 2020, actively detecting insulting expressions even in the absence of profanity. Naver has continued upgrading the system to block expressions that cause sexual discomfort, as well as hatred, disparagement, discriminatory expressions, and circumvented malicious comments using symbols and characters.
In addition, the company is actively cooperating with external bodies to establish a healthy communication environment, including reflecting the Korea Internet Self-Governance Organization (KISO) guidelines on hateful expressions in 2023.
"Naver is continuously strengthening Cleanbot's performance to detect not only profanity and vulgar language but also newly emerging expressions of hatred, disparagement and discrimination," Kim Soo-hyang, a leader at Naver, said. "We plan to advance Cleanbot's performance by listening to diverse opinions, including on intensive blocking of content that promotes disregard for life, mocks victims and bereaved families, and spreads hatred."
