What is it about?
How does the chunking strategy impact the performance of your RAG application? Nobody knows for sure, but this paper is the first step. By pioneering a new way of evaluating document chunking, this paper provides a new hope for expanding our understanding of the inner workings of RAG applications.

Why is it important?
RAG systems are widely adapted in both industry and academia, and have enormous impact on a variety of fields. Nevertheless, little to no reaserch is done on the chunking process, although it is an essential part of all RAG applications. This paper provide new insights into the chunking process, thus expanding our knowledge about RAG systems.
Perspectives
A new HOPE intends to start a new line of research soly focusing on how to topically transform large corpuses into text segments that are optimal for LLMs, rather that humans. This paper does not have all the answers to chunking, but it pioneers a new path that hopefully leads to new reaserch on chunking and text pre-prosessing for LLM-based applications.
