초록

품사 부착 말뭉치의 품질은 품사 부착기를 개발하는데 있어서 매우 중요한 역할을 수행한다. 그러나 세종말뭉치를 비롯하여 한국에서 구축된 많은 품사 부착 말뭉치들은 여전히 다양한 형태의 오류를 포함하고 있다. 이런 오류들을 살펴보면 품사 부착 오류는 물론이고 철자 오류, 문자의 삽입 및 삭제 등 매우 다양하다. 본 논문에서는 오류 패턴을 이용하여 품사 부착 오류를 검출하고 이를 효과적으로 수정하는 도구를 개발한다. 제안된방법과 도구를 이용해서 오류를 수정할 경우 평균 9배 이상 빠르게 오류를 수정할 수 있어서 이 방법이 매우 효과적인 방법임을 확인할 수 있었다.

Abstract

The quality of the part-of-speech (POS) annotation in a corpus plays an important role in developing POS taggers. There, however, are several kinds of errors in Korean POS-tagged corpora like Sejong Corpus. Such errors are likely to be various like annotation errors, spelling errors, insertion and/or deletion of unexpected characters. In this paper,we propose a method for detecting annotation errors using error patterns, and also develop a tool for effectively correcting them. Overall, based on the proposed method, we have hand-corrected annotation errors in Sejong POS Tagged Corpus using the developed tool. As the result, it is faster at least 9 times when compared without using any tools. Therefore we have observed that the proposed method is effective for correcting annotation errors in POS-tagged corpus.
