MOTIVATION AND GOALS

Multimodal recommender systems are transforming the way we experience digital services, enabling smarter and richer recommendations in domains such as fashion, music, food, e-commerce, and digital media. By combining data from images, text, audio, video, and other heterogeneous signals, these systems can support richer user profiling and more accurate recommendations than traditional single-modality approaches.

However, multimodal recommender systems are highly sensitive to the quality of the data they rely on. Noisy inputs, missing modalities, duplicated or weakly supervised data, misaligned information across modalities, and embedded biases can significantly affect system performance, robustness, explainability, and fairness.

DaQuaMRec, the 2nd International Workshop on Data Quality-Aware Multimodal Recommendation, brings this foundational concern to the forefront. The workshop offers a dedicated venue to discuss how data quality shapes multimodal recommendation pipelines, from data collection and preprocessing to modeling, evaluation, and deployment. Its goal is to foster focused discussions and catalyze new research on understanding, evaluating, and improving data quality in multimodal recommendation settings.

* Bias in multimodal data
* Preference misalignment across modalities
* Fairness issues in multimodal recommendation
* Assessing multimodal data quality in recommendation

CONTRIBUTION FORMATS

DaQuaMRec welcomes submissions in the following categories:

Research Papers:
Long papers, up to 8 pages excluding references, should present original work that makes a clear and novel contribution and is positioned with respect to the state of the art.
Short papers, up to 4 pages excluding references, may present early-stage research, promising ideas, negative results, or thought-provoking perspectives that can stimulate discussion and future work.

Reproducibility and Resource Papers:
Long papers, up to 8 pages excluding references, should present substantial contributions such as comprehensive tools, large-scale datasets, benchmarks, or in-depth reproducibility analyses.
Short papers, up to 4 pages excluding references, may describe smaller-scale resources, focused tool descriptions, or preliminary reproducibility efforts of interest to the community.

Position Papers:
Position papers, up to 2 pages excluding references, are intended for short, critical, or visionary contributions that highlight future directions, emerging challenges, or reflective perspectives on the field. They should aim to spark discussion and inspire future research, even in the absence of experimental results.

SUBMISSION AND PUBLICATION

Submissions are open.

Submit your paper through EasyChair at:

Please make sure to select:
Second International Workshop on Data Quality-Aware Multimodal Recommendation

All submissions must be written in English, submitted as PDF files, and formatted using the CEUR-WS single-column conference format.

All submissions will undergo a double-blind peer review process. Review criteria include relevance to the workshop, originality, significance of the contribution, technical soundness, clarity of presentation, quality of references, and reproducibility.

Authors are encouraged to share code and supplementary material through an anonymous repository to support reproducibility. Submissions that are not properly anonymized, do not follow the required formatting, or disregard the submission guidelines may be rejected without review.

Accepted long and short papers will be published in the CEUR Workshop Proceedings and presented in the main workshop program. Position papers will also be included in the proceedings, and a selection of them may be invited for oral presentation.

At least one author of each accepted paper must register for and attend the workshop in order to present the work.
