Joint Campaign with National Institute of Korean Language and National Hangul Museum on 100th Anniversary of Hangul Day
SK Telecom (SKT) has analyzed Korean language dictionary manuscripts from over 100 years ago using its proprietary AI foundation model to create a new font and has compiled rediscovered pure Korean words that have disappeared from daily use into a book. This is a case where AI technology has been applied to restore historical records of the Korean language on the occasion of the 100th anniversary of Hangul Day's establishment.
SKT announced on the 7th that it will launch the "2026 Malmoi" campaign in commemoration of the 100th anniversary of Hangul Day's establishment in collaboration with the National Institute of Korean Language and the National Hangul Museum.
The company analyzed scanned versions of the Korean language dictionary manuscript "Malmoi" left by Professor Ju Si-gyeong and his students, along with native Korean word data from the Standard Korean Dictionary and "Urimalssem," a crowdsourced Korean language knowledge encyclopedia, using the AI foundation model "A.X K2" to create the "Malmoi Font" and select 100 pure Korean words.
The book of 100 pure Korean words will be distributed on the 8th and is scheduled to be donated to the National Hangul Museum.
The "Malmoi Font" was completed by having A.X K2 analyze the character images of the entry 'ㄱ (galJuk)' remaining in the manuscript and extract the forms of consonants and vowels.
SKT announced that the completed font can be downloaded free of charge from the Korean Language Society website.
The criteria for selecting the 100 pure Korean words are: △words with lyrical or positive connotations in their definitions △words that do not sound awkward even when used in the present day △words that can be used in titles, names, and subtitles, etc.
The selection results include △'Yunseul' meaning small ripples that sparkle in reflected sunlight or moonlight △'Sutnun' referring to clean snow in its accumulated state △'Boleumul' referring to dimples △'Puthnat' meaning acquaintances familiar enough to recognize each other's faces, and others.
The final list underwent verification by the National Institute of Korean Language.
In addition to written records, audio recordings have also been included in this campaign.
A campaign video utilizing voice recordings of Korean language scholar Professor Yi Guk-ro, kept at the French National Library, was released on SKT's YouTube channel on the 7th.
The video captures the process of Korean language records from 100 years ago being connected through AI to fonts and speech.
Customer participation-type SNS events are also being conducted simultaneously.
SKT will post reels and card news featuring dialects and new terminology on its official SNS accounts, and plans to provide selected event participants with special edition "2026 Malmoi" books and "2026 Malmoi Font" keycaps through a drawing.
Lee Seung-yeol, Head of Strategy and Communications at SKT, stated, "We prepared this campaign so that the Korean language collected by our ancestors over 100 years ago can be carried forward through AI and shared by everyone as a font and language." He added, "We will continue to work to ensure that AI can be used to preserve the value of the Korean language and our culture."
