I am a final-year Ph.D. student in the Language Technologies Institute of the School of Computer Science at Carnegie Mellon University, working with my fantastic advisor, Eduard Hovy. I interned at Facebook AI, Allen Institute for AI (AI2), and Microsoft Research. My Ph.D. study has been supported by Allen Institute for AI (AI2) Fellowship, CMU Presidential Fellowship, and ILJU Graduate Fellowship. In the middle of my study, I completed my alternative military service in South Korea at Naver Labs and KAIST Institute. Before joining CMU, I obtained my BS and MS in Computer Science Engineering at KAIST, Korea.
Neural-symbolic integration for knowledge-augmented generation. The open-ended QA is a sub-task of language generation where external knowledge and its reasoning (“what” in Ideational metafunction) are required to answer the question. To take advantages of two opposing systems (neural and symbolic), I developed three ways of neural-symbolic integrated systems through embedding representations, data [ACL18adventure], and modules [EMNLP18nsnet], filling the knowledge gaps of the neural system and showing the state-of-the-art performance on the science QA tasks.
Text-planning for coherently-structured generation. A multi-text document (e.g., a paragraph) itself contains various forms of inductive structures that can be linguistically represented: co-reference, discourse, scripts, and more. Our proposed text-planning approach horizontally or vertically controls the high-level plans (“how” in Textual) using the linguistic structures before the surface realization. Our results show that the linguistic structures (e.g., relations [EMNLP19flownet][EMNLP17cgraph], scripts, policies [EMNLP19gorecdial], aspects [NAACL18peerread]) guide to produce more coherent text in different paragraph completion tasks.
Cross-stylization for stylistic generation. Style is a strategic choice of text for some personal or social goal (“who” in Interpersonal). It is formed by a complex combination of different stylistic factors, including formality, emotions, personal demographic traits, etc. Studying the nature of the co-varying combinations across different styles shed light on stylistic language in general called crossstylization. We addressed two fundamental challenges in the cross-style study: (1) the lack of parallel dataset to address the semantic drift [EMNLP19pastel] and (2) the lack of benchmark for cross-style correlation study [ARXIV19xslue].
