New MOSAIC system tackles sparse user reviews for better recommendations

Researchers have developed MOSAIC, a novel meta-review system designed to improve recommendation accuracy by addressing sparsity and incompleteness in user-generated content. Unlike existing methods that struggle with missing or partial reviews, MOSAIC aggregates attribute-sentiment evidence from neighboring users' reviews to construct a meta-review for each target user. This approach, utilizing a multi-gate mixture-of-experts architecture and an attention module, enhances both rating predictions and the quality of attribute-level explanations, outperforming state-of-the-art baselines on real-world datasets.

    Beyond a Single Story: Meta-Reviewing Sparse and Incomplete User-generated Contents for Recommendation

    Data sparsity remains a long-standing challenge in recommender systems, and it becomes more severe for methods relying on user-generated content (UGC) such as textual reviews, which capture fine-grained preferences but require more user efforts to produce. As a result, UGC exhibi…
