Within the first a part of this collection, I launched you to my artificially created pal John, who was good sufficient to offer us along with his chats with 5 of the closest individuals in his life.

And naturally, we won’t undergo the messages one after the other and classify them — no, we are going to use the Python library BERTopic to extract the matters that the chats revolve round.
