+# 📚 AWS PDF Chunk Dataset
+
+This dataset consists of chunked text extracted from **all publicly available PDF documents on the Amazon Web Services (AWS) official website**. The data includes whitepapers, user guides, technical documentation, and best practice manuals—covering **virtually every AWS service, concept, and architecture** in depth.
+
+It is designed to serve as a high-quality knowledge base for use in **embedding generation, vector databases, and retrieval-augmented generation (RAG)** systems.
+

+
+## 📦 Dataset Structure
+
+The dataset is provided as a `.json` file. Each entry corresponds to a text chunk extracted from a PDF document using a sliding window with **800-token chunks and 100-token overlap**. This preserves semantic continuity and improves embedding-based retrieval performance.
+
