PILAR: A Page-Grounded Unified Evidence Representation via an Entity-Linked Assertion Graph for Open-Domain QA Agents over Multimodal Document Corpora
EMNLP 2026 · Findings · Aug 2026
Abstract
PILAR unifies text, tables, and figures from multimodal document corpora into a single page-grounded evidence representation. Assertions are linked through shared entities into a graph, giving open-domain QA agents structured, traceable evidence across pages and documents.
Key Contribution
Entity-linked assertion graphs unify text, tables, and figures into a single page-grounded evidence representation for open-domain multimodal QA agents.
