Abstract

Author resolution is to disambiguate same-name author occurrences into real individuals. For this, pair-wise author similarities are computed for author name entities, and then clustering is performed. So far, many studies have employed hierarchical clustering techniques for author disambiguation. However, various hierarchical clustering methods have not been sufficiently investigated. This study covers an empirical evaluation and analysis of hierarchical clustering applied to Korean author resolution, using multiple distance functions such as Dice coefficient, Cosine similarity, Euclidean distance, Jaccard coefficient, Pearson correlation coefficient.

저자식별은 학술문헌에 출현한 동명저자명들을 실세계의 서로 다른 사람들로 대응시키는 것이다. 이를 위해 임의의 동명저자명쌍의 유사도를 계산하고 이를 바탕으로 동명저자명 개체들을 군집화하는 단계를 거친다. 저자명의 군집화 기법으로 주로 계층적 군집법이 사용되었으나 다양한 계층적 군집법에 대한 비교 평가는 미흡했다. 이 연구는 다이스계수, 코사인유사도, 유클리디안 거리, 자카드계수, 피어슨 상관계수 등의 다양한 개체거리/유사도수식과 계층적 군집법들의 상관관계와 계층적 군집기법들의 한글 저자식별 성능에 대한 비교/분석을 다룬다.
