Overview of the EReL@MIR 2025 Multimodal Document Retrieval Challenge (Track 1)
Published in arXiv preprint
This report describes the Multimodal Document Retrieval Challenge (Track 1 of the MIR Challenge) at the first EReL@MIR workshop, co-located with The Web Conference 2025: challenge design, datasets, and evaluation protocol across closed-set document page retrieval (MMDocIR) and open-domain image-based retrieval (M2KR), final standings, and an analysis of the three winning systems. The challenge drew 22 teams, 455 entrants, and 586 submissions; all three winning systems build on decoder-based Multimodal-LLM embedders from the Qwen2-VL family rather than CLIP-style encoders.
