• KeyBERT

  5 3,585 6.5 Python

  Minimal keyword extraction with BERT

• yake

  5 1,656 3.0 Python

  Single-document unsupervised keyword extraction

  

  You can look for usage here: https://github.com/LIAAD/yake and there is also a reference section with publications for more details of how this works. From what I remember, each keyphrase candidate is assigned an aggregated score based on various features: position in the text, casing, frequency, surrounding text frequency...

• scattertext

  3 2,257 3.7 Python

  Beautiful visualizations of how language differs among document types.

  Other suggestions: Take a look at Scattertext. Compare keywords to the problem of aspect extraction. I think an underutilized way to look at textual data when you have a single group of interest is the word-frequency-based odds ratio.
