[交流] 大数据分析材料类SCI论文的用词 —— Results and Discussion 部分

本文内容来源于《破解SCI 论文写作奥秘》。

文中，作者将大数据与SCI 论文进行有机结合，通过自然语言处理技术，得到SCI论文的各部分的用词频率统计情况，以期对材料类科研工作者的SCI 论文写作提供一定的帮助。

具体的处理步骤如下：

（1）将PDF格式的论文转换为txt格式；

（2）去除噪声信息（如论文页面边角信息、页眉、引文等）；

（3）文献按 Introduction、 Experiment、 Results and discussion、 Conclusions 分块；

（4）自然语言处理技术进行处理；

（5）标注词性及去除错误；

（6）得到词频统计情况。
