- W45917232 abstract "구문 분석에서 가장 큰 문제점 중 하나는 구문 구조의 중의성을 어떻게 해결하느냐에 달려있다. 확률 구문 규칙은 구문 구조의 중의성 해결에 한 방법이 될 수 있다. 본 논문에서는 중심어 간의 공기정보를 이용하여 한국어 구문 구조의 중의성을 해결하는 확률 모델을 제안하고자 한다. 중심어는 어휘를 이용하기 때문에 자료 부족 문제를 야기시킬 수 있다. 이 때문에 자료부족 문제를 어떻게 해결하느냐에 따라 어휘 정보 사용의 성공이 결정될 수 있다. 본 논문에서는 구문규칙을 단순화하고 Back-off 방법을 이용해서 이 문제를 완화한다. 제안된 모델은 실험 데이터에 대해 약 84%의 정확도를 보였다. Since a natural language has inherently structural ambiguities, one of the difficulties of parsing is resolving the structural ambiguities. Recently, a probabilistic approach to tackle this disambiguation problem has received considerable attention because it has some attractions such as automatic learning, wide-coverage, and robustness. In this paper, we focus on Korean probabilistic parsing model using head co-occurrence. We are apt to meet the data sparseness problem when we're using head co-occurrence because it is lexical. Therefore, how to handle this problem is more important than others. To lighten the problem, we have used the restricted and simplified phrase-structure grammar and back-off model as smoothing. The proposed model has showed that the accuracy is about 84%." @default.
