Meta-Chunking: Learning Text Segmentation and Semantic Completion via Logical Perception

Jihao Zhao, Zhiyuan Ji, Yuchen Feng +5

While Retrieval-Augmented Generation (RAG) has emerged as a promising paradigm for boosting large language models (LLMs) in knowledge-intensive tasks, it often overlooks the crucia…
