초록
국내 학술회의 논문으로 구성된 문헌집합을 대상으로 기계학습에 기초한 자동분류의 성능에 영향을 미치는 요소들을 검토하였다. 특히 구현이 쉽고 컴퓨터 처리 속도가 빠른 로치오 알고리즘을 사용하여 『한국정보관리학회 학술대회 논문집』의 논문에 주제 범주를 자동 할당하는 분류 성능 측면에서 분류기 생성 방법, 학습집합 규모, 가중치부여 기법, 범주 할당 방법 등 주요 요소들의 특성을 다각적인 실험을 통해 살펴보았다. 결과적으로 분류 환경 및 문헌집합의 특성에 따라 파라미터(β, λ)와 학습집합의 크기(5년 이상)를 적절하게 적용하는 것이 효과적이며, 동등한 성능 수준이라면 보다 단순한 단일 가중치부여 기법을 사용하여 분류의 효율성을 높일 수 있음을 발견하였다. 또한 국내 학술회의 논문의 분류는 특정 논문에 하나 이상의 범주가 부여되는 복수-범주 분류(multi-label classification)가 실제 환경에 부합한다고 할 수 있으므로, 이러한 환경을 고려하여 주요 성능 요소들의 특성에 기초한 최적의 분류 모델을 개발할 필요가 있다.

Abstract
This study examined the factors affecting the performance of automatic classification for the domestic conference papers based on machine learning techniques. In particular, In view of the classification performance that assigning automatically the class labels to the papers in Proceedings of the Conference of Korean Society for Information Management using Rocchio algorithm, I investigated the characteristics of the key factors (classifier formation methods, training set size, weighting schemes, label assigning methods) through the diversified experiments. Consequently, It is more effective that apply proper parameters (β, λ) and training set size (more than 5 years) according to the classification environments and properties of the document set. and If the performance is equivalent, I discovered that the use of the more simple methods (single weighting schemes) is very efficient. Also, because the classification of domestic papers is corresponding with multi-label classification which assigning more than one label to an article, it is necessary to develop the optimum classification model based on the characteristics of the key factors in consideration of this environment.
