The workshop PROGRAM is out!!
📢 We're in contact with the EiC of ACM TORS to propose a
Special Issue on similar (and more broader) topics discussed at DaQuaMRec... stay tuned!! 📢
Multimodal recommender systems transform how we experience digital services, powering smarter suggestions in fashion, music, food, and beyond. Combining data from images, text, and audio, these systems outperform traditional, single-modality approaches, enabling richer user profiling and more accurate recommendations.
Driven by advances in deep learning and the rise of large foundation models, the multimodal recommendation is progressing remarkably. Yet, beneath the surface of these powerful models lies a crucial, often-overlooked challenge: data quality [Demartini et al., Wang et al.].
DaQuaMRec, the First International Workshop on Data Quality-Aware Multimodal Recommendation, brings this foundational concern to the forefront. While state-of-the-art models continue to evolve, their performance and fairness are tightly bound to the quality of the data they rely on.
Noisy inputs [Zhang et al., Yu et al.], missing modality information [Ganhör et al., Malitesta et al. (2024)], misaligned data [Li et al. (2024), Xv et al.], and embedded biases [Liu et al., Malitesta et al. (2023)] can all degrade system performance and lead to inaccurate or unfair recommendations [Shang et al., Li et al. (2025)]. This workshop offers a dedicated space to explore these pressing issues.
Our mission is to foster deep, focused discussions and catalyze new research aimed at understanding, evaluating, and improving data quality in multimodal recommendation settings.
We are in direct contact with the Editors of ACM TORS regarding the proposal for a Special Issue, where we will invite the most interesting papers accepted at DaQuaMRec to submit!
