Abstract

The goal of this paper is to explore the field of Computer and Information Science with the aid of text mining techniques by mining Computer and Information Science related conference data available in DBLP (Digital Bibliography & Library Project). Although studies based on bibliometric analysis are most prevalent in investigating dynamics of a research field, we attempt to understand dynamics of the field by utilizing Latent Dirichlet Allocation (LDA)-based multinomial topic modeling. For this study, we collect 236,170 documents from 353 conferences related to Computer and Information Science in DBLP. We aim to include conferences in the field of Computer and Information Science as broad as possible. We analyze topic modeling results along with datasets collected over the period of 2000 to 2011 including top authors per topic and top conferences per topic. We identify the following four different patterns in topic trends in the field of computer and information science during this period: growing (network related topics), shrinking (AI and data mining related topics), continuing (web, text mining information retrieval and database related topics), and fluctuating pattern (HCI, information system and multimedia system related topics).

이 논문의 연구목적은 컴퓨터공학 및 정보학 관련 연구동향을 분석하는 것이다. 이를 위해 텍스트마이닝 기법을 이용하여 DBLP(Digital Bibliography & Library Project)의 학술회의 데이터를 분석하였다. 대부분의 연구동향 분석 연구가 계량서지학적 연구방법을 사용한 것과 달리 이 논문에서는 LDA(Latent Dirichlet Allocation) 기반 다항분포 토픽모델링 기법을 이용하였다. 가능하면 컴퓨터공학 및 정보학과 관련된 광범위한 자료를 수집하기 위해서 DBLP에서 컴퓨터공학 및 정보학과 관련된 353개의 학술회의를 수집 대상으로 하였으며 2000년부터 2011년 기간 동안 출판된 236,170개의 문헌을 수집하였다. 토픽모델링 결과와 주제별 문헌 수, 주제별 학술회의 수를 조사하여 2000년부터 2011년 사이의 주제별 상위 저자와 주제별 상위 학술회의를 제시하였다. 주제동향 분석 결과 네트워크 관련 연구 주제 분야는 성장 패턴을 보였으며, 인공지능, 데이터마이닝 관련 연구 분야는 쇠퇴 패턴을 나타냈고, 지속 패턴을 보인 주제는 웹, 텍스트마이닝, 정보검색, 데이터베이스 관련 연구 주제이며, HCI, 정보시스템, 멀티미디어 시스템 관련 연구 주제 분야는 성장과 하락을 지속하는 변동 패턴을 나타냈다.
