Seems like a lot. For me, it's 0 close friends, 0 regular contacts, and 0 active acquaintances. I think I simply never developed any useful social skills which would help me make and keep friends or acquaintances. I wish I had (somehow) kept in touch with at least some people I have met throughout my life. It has never been easier to stay in contact than in all of human history, but no, I had to ghost and ignore everyone and everything. After 29 revolutions around the sun, I have only now started to realize that all that vacuous superiority has led me nowhere. There is only a faint aftertaste of missing out, which sticks to me like tar. I can’t wash it off.

For removing noise you might want to look into TF-IDF instead of the manual method described in the post that I didn't understand. It basically looks for words common across the whole corpus as noise or ones that appear within a specific chat much higher than the whole dataset as interesting.

You can also do some fun stuff by finding phrases used asymmetrically eg more by one person in the convo than the other, or over time.

Wordclouds per person are also fun!

I find text messages impersonal and it also takes longer to communicate clearly what we need. There is so much lost. Even chats and emails for work are at risk of creating misunderstanding, especially because English is not the native language of most of my coworkers, all these adds to result in pretty low quality communication.

Don't think there is a way to recover that.. right?
