Why Naive Text Chunking Breaks RAG and How to Build a Better Alternative

The article explains how simple character‑ or page‑based chunking destroys the spatial and semantic relationships of tables, figures, formulas and headings in PDFs, proposes a structure‑aware multimodal RAG pipeline that restores layout via layout detection, visual description generation, modal enhancement and cross‑encoder re‑ranking, and shows that these steps dramatically improve retrieval quality, especially for visual queries.

Image-to-UI Code Generation Demo and Architecture Overview

The Xianyu team’s new “black‑tech” system automatically transforms UI mockup images into production‑ready code by detecting components with deep‑learning models, extracting layouts via OpenCV, and employing a modular stream‑oriented architecture of units, tasks, and server layers that enables rapid testing, flexible composition, and future enhancements such as improved container recognition and semantic understanding.
