Introduction

빅데이터 연구실은 실용적 어플리케이션 연구에 초점을 맞추어 Twitter, Facebook, IMDB, Yelp 등 다양한 소셜 미디어에서 수집되는 대규모 다형성(heterogeneous) 데이터를 연구합니다. 예를 들어, 트위터의 그래프 형태의 소셜 네트워크 관계와 텍스트 형태의 메시지(micro-blogging), GPS 위치정보 등 서로 성질이 다른 다양한 데이터 형태로부터 클러스터링, 패턴 마이닝, 추천 시스템 등을 개발합니다. 현재는 인간 행동(human behavior)의 패턴을 분석하여 트위터의 텍스트와 GPS 위치정보를 통해 여행자의 경로 패턴을 찾거나 Q&A서비스의 데이터 분석을 통해 분야별 전문가 찾기와 같은 연구를 수행하고 있습니다. 연구에 활용되는 기반 기술로서 MapReduce를 이용한 병렬컴퓨팅, 데이터마이닝 기법, 데이터 베이스, 자연어처리, 머신 러닝과 딥러닝 등을 폭 넓게 학습합니다.

We study real data mining problems in social media such as Twitter, Facebook, IMDB and Yelp. We focus on developing clustering, pattern mining and recommendation algorithms by analyzing big heterogenous data with various types including micro-blog message, GPS location and friend relationship. In this research direction, our group has been investigated the discovery of interesting and useful patterns in human behavior such as traveling trajectory patterns from geo-tagged Twitter messages and expert detection by analyzing Q&A dialogues collected from Stack Overflow. We expect our members to: Develop sufficient expertise in recent knowledge mining techniques and Become skillful in managing big data with various data processing models such as MapReduce frameworks and NoSQLs.
