  Use of chatbots for emotional exchange is recently increasing in various domains. However, as existing chatbots have been considered in terms of natural language processing techniques for interaction with text-based chatting, there are problems with the flow and the style of the conversation. Consequently, chatbot interaction with users is lacking in terms of considering the emotions of users and managing turn-taking in conversation. We suggest a new interaction technique having touch interactions with graphic interfaces (TwG) to solve these problems. In the proposed system, users send their emotions and manage turn-taking through TwG technique. This project is a part of DGIST UGRP (Undergraduate Group Research Program), and the research is supported by DGIST UGRP Grant.

I am one of the project leader of Harooo Communication. A representative service is SNS 'Harooo' where writings last 24 hours. Harooo Communication was announced by media, and members of Harooo Communication are supported by NAVER. There are many projects in Harooo Communication.

Since 2018, I have been an undergraduate tutor of DGIST. In 2018, I worked as a tutor of General Chemistry I in the first semester and Multivariable Calculus in the second semester. In 2019, I worked as a tutor of Linear Algebra in the first semester and Object-Oriented Programmin in the second semester. Now, I am working as a tutor of Data Structure for this semester. While I have been working as a tutor, I try to fill the gaps which I did not understand when I was a fresher student. Thanks to the efforts, I was selected as a superb tutor in the first semester of 2018, and the second semester of 2019.

  There are two types of vocabulary knowledge - vocabulary size & vocabulary control. Generally, non-native Speakers are hard to control vocabulary in English writing. Therefore, we studies on how to support controlling vocabulary in English writing. Our basic approach is using NLP-based interactions to teach knowledges of vocabulary control. In current prototype, learners can learn a specific word and write an example sentence using the word. After that, our prototype fixes and paraphrases the sentence using Transformer-based Language Model (Bert, GPT2).

  To help language learners achieve fluency, instructors often focus on teaching formulaic sequences (FS)–phrases such as idioms or phrasal verbs that are processed, stored and retrieved holistically. Teaching FS effectively is challenging as it heavily involves instructors’ intuition, prior knowledge, and manualefforts to identify a set of FSs with high utility. We suggest FSIST, a tool that supports instructorsfor video-based instruction of FS. The core idea of FSIST is to utilize videos at scale to build a list of FSs along with videos that include example usages. To evaluate how FSIST can effectively supportinstructors, we conducted a user study with three English instructors. Results show that the browsing interactions provided in FSIST support instructors to efficiently find parts of videos that show example usages of FSs.
