| 摘 要： | 目的/意义]学术文本结构功能是对学术文献的结构和章节功能的概括,针对当前研究较少从学术文本多层次结构出发进行融合和传统方法依赖人工经验构建规则或特征的问题,本文在对学术文本层次结构进行解析的基础上,构建了多层次融合的学术文本结构功能识别模型。方法/过程]以ScienceDirect数据集为例进行实验,该模型首先通过深度学习方法对不同层次学术文本进行结构功能识别,接着采用投票方法对不同层次和不同模型的识别结果进行融合。结果/结论]研究结果表明各层次集成后的整体效果较单一模型均有不同程度提升,综合结果的整体准确率、召回率和F1值分别达到86%、84%和84%,并且深度学习算法在学术文本分类任务中的性能较传统机器学习算法SVM更优,最后对学术文本结构功能错分情况进行了分析,指出本研究潜在的应用领域和下一步的研究方向。

| Abstract: | Purpose/significance] The structure function of the academic text refers to the summarization of academic text structure and section function. While few of existed studies pay attention to the fusion of multi-level structure of academic text, and the traditional methods usually rely on artificial experience to build rules or features. After the analysis of the multi-level structure of academic text, we construct a structure function recognition model based on multi-level fusion.Method/process] We use the academic text dataset from ScienceDirect for experiment. First, we apply deep learning algorithms to identify the structure function of academic text at different level. Then we employ the voting method to fuse the results from different levels and models.Result/conclusion] The results show that the performance improved to varying degrees after fusion. The precision, recall and F1 value of the combined results reached 86%, 84% and 84%, respectively. Compared with the traditional machine learning algorithm SVM, the deep learning algorithm has better performance in the task of academic text classification. Finally, we analyze the misclassification of the structure function of academic text and point out the potential application fields and future research directions. |
