What is content aware chunking?

Using content appropriate delimiters to create the chunks. If its a Python document, split it at the proper delimiters. If its an HTML document, JSON, etc. We wouldn't want to split a chunk in the middle of a function or paragraph. Or maybe we would. But that is what OP is refering to I believe.

That's a good point, and documents too needs different chunking techniques. You don't want to split a word file the same way you split an excel...

Yes, this is on the shortlist.

Do you have any preferred frameworks?

I haven't found any frameworks that offer it. The best explanation of an implementation that can take a stream of unformatted text and map over it to determine when a topic changes is explained in this video: https://youtu.be/8OJC21T2SL4?t=1932

They compute embeddings using a window of three sentences and then compute distance to find the largest deltas to break up the text into "topics". It is computationally expensive.

I just noticed this has been added to langchain: https://python.langchain.com/docs/modules/data_connection/do...
