Link to GitHub?

https://github.com/citiususc/pyplexity . My bad :)

All good, might want to link the other ones you posted in those other post comments, too (Smarty-GPT, etc) -- most of the time you can just link the GitHub directly from the post here.

My bad, quite a newbie: https://github.com/citiususc/Smarty-GPT

so... what are perplexity filters ?

A perplexity filter allows to remove sentences by likelihood to a given language model. In there you need to "play" with the parameter or threshold

Mind elaborating?

Sure! The idea is that you create a language model from a given corpus (let's say BNC) and then you use a similarity measure, in this case, perplexity, but can be another one to test how well your sample (sentence) "fits" into the model distribution. Since we assume the distribution is correct, this allows us to identified malformed sentences.
