Optimizing your chunking techniques is one of the top places to improve performance in your RAG pipelines, but what’s the best one? Jina AI just released a new method called late chunking that takes the same amount of storage space as naive chunking, but solves the problem of lost... show more

The paper addresses the problem of lost context information when using traditional "chunking" approaches in text retrieval systems. In such systems, long documents are often split into smaller chunks before encoding them into vector representations. However, this can lead to the loss of contextual information from surrounding chunks, resulting in suboptimal representations. The paper presents both a qualitative and quantitative evaluation of the late chunking method: • Qualitative analysis: The authors demonstrate how late chunking enables the transfer of context information from text values outside of a chunk's span into its embedding representation. • Quantitative evaluation: The authors test late chunking on various retrieval benchmarks and show that it outperforms the traditional chunking approach across all tasks. The improvements are more significant for longer documents, where the context information is more critical. full paper:

@JinaAI_ Yay, another one of these!

@JinaAI_ Excellent breakdown with just enough information to stay up-to-date with recent developments!

@JinaAI_ 👏👏

@JinaAI_ Great info! I’m going to experiment with late chunking.

@JinaAI_ super interesting approach

@JinaAI_ ♥️
