TL;DR
DIAGRAMS is a flexible review framework that streamlines reasoning-level attribution in Diagram QA by decoupling interface design from dataset-specific formats, enabling efficient evidence annotation and verification.
Contribution
It introduces DIAGRAMS, a schema-driven, dataset-agnostic review system that automates evidence selection and generation for reasoning in Diagram QA tasks.
Findings
Model-suggested evidence achieves 85.39% precision.
Recall of 75.30% against reviewer selections.
Reduces manual effort in region annotation.
Abstract
Diagram question answering (Diagram QA) requires reasoning-level attribution that links each question-answer pair to all visual regions needed to derive the answer, rather than only the region containing the final response. Creating such structured evidence across diagrams, charts, maps, circuits, and infographics is time-consuming, and existing annotation tools tightly couple their interfaces to dataset-specific formats. We present DIAGRAMS, a lightweight, schema-driven review framework that decouples interface logic from dataset-specific JSON structures through an internal meta-schema and dataset adapters. Given an image and QA pair with optional candidate regions, the system performs QA-conditioned evidence selection and proposes the regions required for reasoning. When QA pairs or candidate regions are missing, it generates them and supports human verification and refinement. Across…
