KT announced on the 22nd that it has been operating a real-time spam blocking keyword registration system based on artificial intelligence (AI) since last month. This system has significantly reduced the lead time to real-time levels compared to the previous manual method, minimizing customer damage and greatly enhancing spam response efficiency.
KT has been operating a system that derives spam keywords by analyzing spam report data received from the Korea Internet & Security Agency (KISA) and blocks them. Previously, manually analyzing and registering keywords could take more than a day, but the introduction of the AI-based system has allowed for real-time reductions in registration time. As a result, it is now possible to register spam keywords on weekends or at night, establishing a 24-hour response system.
The pilot operation results showed that the number of spam blockages increased by 150% on the same day after the introduction of the AI system, and while the keywords registered by AI accounted for only 5.5% of the total keywords, the proportion of blockages caused by these keywords reached 45.9%, demonstrating high efficiency. This efficiency allows the spam customer service response personnel to focus more on sophisticated spam types such as investment solicitations and inducing conversations on social media.
Lee Byeong-mu, head of KT AX Innovation Support Division (Executive Director), noted, "Through the AI real-time keyword registration system, we are now able to respond quickly to spam that occurs on the same day," adding, "In the future, we plan to continuously enhance the accuracy and processing scope to respond to sophisticated spam such as mutated spam using the AI blocking model."
