More about me

Personal characteristics
  • ESTJ in 2007, INFP in 2018.
  • Friends call me a dreamer or romantist to a fault - but I enjoy living my life as such.
  • I am a productivity geek, and spend much of my free time automating things.
  • I easily get addicted to things, so I don't start things easily.
Things I love
  • Riding my bike, swimming, scuba diving, playing the piano and making my own fresh coffee with a siphon.
  • Adventures, smiling, learning, and pursuing community action.
  • Exploration, as opposed to exploitation. I particularly enjoy exploring the realm of cuisines. I have two particular dishes I do not enjoy -- 홍어, 추어탕 -- but who knows? I may even come to like these in the future.
  • Openness, sharing, and cooperation (ex: Everyware)

My life goal is to lower the barriers of knowledge through data. I am currently working for NAVER Papago – and lowering the barriers of linguistic knowledge by building machine translation models. Current areas of interest include context-aware machine translation, and translation evaluation. You can often find me on the Web as Eunjeong, echojuliett, echojuli&t, e9t.

The Korean language is used by more than 80M people and is increasingly gaining popularity due to K-dramas, K-pop, variety shows, and games. However, despite its popularity, it is a minor language in natural language processing research, while most research is carried out in English. During her graduate studies at Seoul National University, Lucy learned that many open source packages for the Korean language were often difficult to access, if not less documented. So in 2014, she developed and released KoNLPy (, an open-source Python package for Korean natural language processing, focused on easy access, usability and scalability. The package picked up many users in Korea and is still widely used for production and educational purposes. She continued her affair for the Korean language while working on Papago, NAVER's machine translation application. She built an honorific-sensitive machine translation model in 2017, which gained popularity from many people learning the Korean language. In 2020 Lucy co-founded Upstage, where she keeps developing AI models to make AI beneficial to many people. Upstage is an AI solution company working on computer vision, recommender systems, and natural language processing. One of the efforts they recently made for the Korean language processing is to lead the initiative for KLUE, a Korean language understanding evaluation benchmark. This is a big deal since the released dataset is one of the first and most extensive Korean datasets free from copyright license issues. Lucy participated in creating data for the machine reading comprehension task. Upstage has earned 8.8 billion won in revenue in just eight months since its founding by providing AI solutions. They will be releasing reusable AI packs in the near future.
