The Second Workshop on Evaluation for Multimodal Generation

Multimodal generation and retrieval systems are increasingly central to modern information retrieval, powering retrieval-augmented generation (RAG), multimodal search, recommendation, and knowledge-intensive applications. Despite rapid progress in multimodal large language models (MLLMs), robust and principled evaluation of multimodal generation and retrieval remains a major open challenge for the IR community. This workshop aims to foster discussions and research efforts by bringing together researchers and practitioners in information retrieval, natural language processing, computer vision, and multimodal AI. Our goal is to establish evaluation methods for multimodal research and advance research efforts in this direction.

CALL FOR PAPERS

Both long papers and short papers (up to 9 pages and 4 pages respectively, with unlimited references and appendices) are welcome for submission.

A list of topics relevant to this workshop (but not limited to):

*

Multimodal retrieval for RAG, Agentic AI, recommendation systems *

Evaluation of retrieved cross-modal samples, without relying on augmented generation *

Multi-aspect evaluation methods capturing inter- and intra-modal coherence, relevance, grounding, and contextual consistency *

Benchmark retrieval datasets, evaluation protocols and annotations for text-image-audio-video-3D generation *

Automatic and human-centric metrics for informativeness, factuality, fluency, faithfulness, calibration, and usability for multimodal generation *

Methodology for detecting, analysing, and mitigating multimodal bias, stereotypes, toxicity, and hallucinations *

Evaluation in multimodal low-resource and multilingual settings, including culturally aware and cross-lingual metrics *

Agent-based evaluation of multimodal generation in multi-turn, tool-use, or iterative editing scenarios *

Game-theoretic or optimization-based formulations of evaluation objectives and protocols *

Evaluation of the generation quality of synthetic multimodal data, provenance/attribution, and downstream impact on training and deployment *

Ethical considerations in the evaluation of multimodal text generation, including bias detection and mitigation strategies *

Evaluation of Security and Privacy Dimensions in Multimodal Applications *
