대용량의 언어 코퍼스를 이용할 때, 오류 어휘가 코퍼스에 포함되어 있는 경우 해당 코퍼스를 이용한 실험의 성능이 저하될 수 있다. 이 때문에 정확한 문장들로 이루어진 코퍼스를 구축하기 위해 다량의 문장 중에서 정확하게 오류 어휘를 탐지할 필요가 있다. 본 논문에서는 대용량 데이터에서 빈도수가 낮은 음절을 이용해 오류 어휘를 탐지하는 방법을 제안하고, 제안 방법을 이용하여 오류 어휘 탐지 시 고려하여야 할 점에 대해 서술한다.

The purpose of developing an automated scoring system for English composition is to score the tests for writing English sentences and to give feedback on them without human's efforts. This paper presents an automated system to score English composition, whose input is a single sentence, not an essay. Dealing with a single sentence as an input has some advantages on comparing the input with the given answers by human teachers and giving detailed feedback to the test takers. The system has been developed and tested with the real test data collected through English tests given to the third grade students in junior high school. Two steps of the process are required to score a single sentence. The first process is analyzing the input sentence in order to detect possible errors, such as spelling errors, syntactic errors and so on. The second process is comparing the input sentence with the given answer to identify the differences as errors. The results produced by the system were then compared with those provided by human raters.
