초록

본 논문에서는 한국어와 중국어의 언어학적인 특징을 고려하여 문서 자동분류 시스템의 성능을 높일 수 있는 최적의 자질어 단위를 제안한다. 언어 종속적 단위인 형태소 자질어와 언어 독립적 단위인 n-gram 자질어 그리고 이들을 조합한 복합 자질어 집합을 대상으로 각 언어의 인터넷 신문기사를 SVM으로 분류하는 실험을 수행하였다. 실험 결과, 한국어 문서분류에서는 bi-gram이 F1-measure 87.07%로 가장 좋은 분류 성능을 보였고, 중국어 문서분류에서는 'uni-gram 명사 동사 형용사 사자성어'의 복합 자질어 집합이 F1-measure 82.79%로 가장 좋은 성능을 보였다.

This paper proposed the optimal attributes for text classification based on Korean and Chinese linguistic features. The experiments committed to discover which is the best feature among n-grams which is known as language independent, morphemes that have language dependency and some other feature sets consisted with n-grams and morphemes showed best results. This paper used SVM classifier and Internet news for text classification. As a result, bi-gram was the best feature in Korean text categorization with the highest F1-Measure of 87.07%, and for Chinese document classification, 'uni-gram+noun+verb+adjective+idiom', which is the combined feature set, showed the best performance with the highest F1-Measure of 82.79%.
