BookRAG (Hierarchical Structure-aware Index-based Approach)

A framework designed for complex documents that keeps the original structure instead of flattening it.

It is powered by BookIndex (Tree + Graph):

- Hierarchical tree → rebuilds document structure (like a table of contents)

- Knowledge graph → maps entities and relationships

- GT-Link → connects every entity to its exact location in the document

Result: better context, deeper reasoning and reliable answers on complex PDFs, manuals and books.
