Element Graph v2.1 — Multimodal Academic Document Retrieval
Typed element graphs derived from three multimodal academic document QA datasets:
SPIQA, SciEGQA, and MMDocIR. Each document is decomposed into a typed graph
with cross-modal edges (caption_of), reference edges (refer_to), and
section-aware structural edges (contains, reading_next, section_next).
The graphs are designed for retrieval research:
- Training supervision via Graph-Relevance Contrastive Loss (GRCL)
- Inference-time graph propagation of retrieval scores
- Same edge-weight schema drives both (single source of truth)

Schema
See SCHEMA.md for full schema definition (node types, edge types, attributes,
target-attribute modifiers).
Provenance
- SPIQA: graph extracted from original LaTeX (
\section{},\ref{}) andall_figuresmetadata. Caption-figure pairs are author-provided. - SciEGQA: graph derived from docling layout parsing + heuristic extraction.
- MMDocIR: graph derived from MMDocIR_layouts.parquet + heuristic extraction.

Images
Image files are NOT included. Download from original dataset sources and look up by (doc_id, eid) — the eid is preserved as the figure filename (SPIQA) or layout_id (MMDocIR).
