摘要 提出了一种基于句法分析的特征提取方法,该方法将对句子成分进行分析,并将其作为特征集的一部分进行实验.实验证明,将句子成分分析结果加入特征集中进行定义的抽取,有较好的正确率和召回率. In the study, a feature extraction method based on syntactic analysis was proposed. The method analyzed the sentence elements, and which were use as a part of the feature set for the experiment. The results indicated that the feature set, into which the feature extracted through sentence analysis was added, has better precision and recall rate.
