搞科研的小伙伴总是会被期刊严苛的引用文献格式搞的很头疼。虽然常用的文献软件可以一键导出BibTex,但由于很多论文在投稿之前都会先发上Arxiv占坑,软件就很可能会把文献引出为来自Arxiv。我用的是Zotero,就有这个毛病。

  因此,如果是IEEE的期刊,最好是直接去IEEE官网搜索并导出引用,否则可以使用谷歌学术。为了减少重复性的动作,我使用selenium来帮我完成这些操作。Selenium是Python的一个爬虫包,具体可以看:Python Selenium库的使用

  在此之前,需要安装的有:

  1、谷歌浏览器。也可以用别的浏览器,具体看上面的Selenium教程。

  2、Selenium控制谷歌浏览器的驱动。网址

  3、配置驱动的环境变量,就是把驱动解压的位置放到PATH里。感觉可有可无,因为代码中还是会用到驱动的位置。

  下面是Python代码,具体操作就是先从IEEE官网找,如果找不到再去谷歌学术找。需要具体配置的地方已在代码中注释:

  IEEE与谷歌学术可能需要VPN,在爬之前要先做好准备。另外IEEE还需要登录机构账号,在此之前也要先登录好。
