Question

使用google-scholar和R，我想知道是谁引用了某篇论文。

现有的包（如scholar）面向H指数分析：研究人员的统计数据。

我想给目标纸作为输入。一个示例网址是：

https://scholar.google.co.uk/scholar?oi=bibs&hl=en&cites=12939847369066114508

然后R应该抓住这些引文页面（谷歌学者分页这些），然后返回一系列引用目标的论文（最多500个或更多引用）。然后我们在标题中搜索关键词，列表期刊和引用作者等。

有关如何做到这一点的任何线索？或者是从字面上刮下每一页？（我可以使用复制和粘贴进行一次性操作）。

似乎这应该是一个通常有用的功能，如播种系统评论，所以有人将它添加到一个包可能会增加他们的H： - ）

Answer 1

尽管有很多可用的Google's API，但基于Google Scholar的API却不可用。因此，尽管在Google Scholar页面上创建网络爬虫可能并不困难，但我不知道它在多大程度上是非法的。选中this。

或者，您可以使用第三方解决方案，例如 SerpApi。这是一个免费试用的付费 API。我们为您处理代理、解析验证码并解析所有丰富的结构化数据。

示例 Python 代码（也可在其他库中使用）：

from serpapi import GoogleSearch

params = {
  "api_key": "secret_api_key",
  "engine": "google_scholar",
  "hl": "en",
  "cites": "12939847369066114508"
}

search = GoogleSearch(params)
results = search.get_dict()

示例 JSON 输出：
