GBN词频单词 vs Physics

Google Books Ngrams是一个大型语料库，由Google计划开发并由Harvard University Library进行托管。该数据集由将Google Books中的数百万本书籍数字化转换成文本格式，再对其进行处理得到的一个结果。 N-grams是指书籍中的连续字节序列，例如单个字母，双字母，三字母，四字母等。Google Books Ngrams数据集记录了每个N-gram在所有可用书籍中出现的频率，并且可以与时间轴一起查询，以便可以观察到从18世纪以来英语中短语的使用趋势。 据数据表明，Google Books Ngrams数据集中含有大约5.2万亿个N-grams。这使得这个数据集成为了一种有用的研究语言和文化变化的资源。此外，该数据集还可用于研究各种研究领域，例如历史，社会学，语言学和文学研究，其中一些领域的研究人员已经使用过Google Books Ngrams数据集来支持他们的研究。 本APP 根据单词在 20120701 和 20220217 Google Books Ngrams 数据集中出现的次数,并且在 20220217 数据集中按频率降序排列,整理出前50000个最常用单词。
