In this paper, we try to classify Korean hedge sentences, which are regarded as not important since they
express uncertainties or personal assumptions. Through previous researches to English language, we found
dependency information of words has been one of important features in hedge classification, but not used in
Korean researches. Additionally, we found that word embedding vectors include the word usage information.
We assume that the word usage information could somehow represent the dependency information.
Therefore, we utilized word embedding and neural networks in hedge sentence classification. We used more than one and half million sentences as word embedding dataset and also manually constructed
12,517-sentence hedge classification dataset obtained from online news. We used SVM and CRF as our
baseline systems and the proposed system outperformed SVM by 7.2%p and also CRF by 1.2%p. This
indicates that word usage information has positive impacts on Korean hedge classification.
