原文摘要

Researchers struggle to find relevant datasets amid the growing volume of data across repositories and scholarly publications. Manual dataset retrieval is time-consuming and often fails to identify valuable resources that are not easily discoverable through direct links or popularity metrics. Dataset recommendation, which aims to identify datasets relevant to a paper, author, or query, has become essential for improving dataset discoverability and reuse. However, this task remains challenging because Scholarly Knowledge Graphs (SKGs) are large-scale, heterogeneous, dynamic, and incomplete. Although openly available SKGs organize scientific knowledge by linking scholarly outcomes, they often lack meaningful connections between datasets, leaving them isolated and underutilized. These graphs contain millions of evolving relations but still suffer from missing or inaccurate metadata, duplicate records, and weak dataset integration. This work presents the Multimodal Scholarly Attention Network (MM-SAN), a heterogeneous multimodal graph representation learning method for recommending datasets relevant to research publications within real-world SKGs. MM-SAN combines topology-aware and text-based embeddings, enabling effective recommendations even when textual metadata is limited or absent. It operates in transductive, semi-inductive, and fully inductive settings, adapting to evolving SKGs without requiring retraining. Experiments show that MM-SAN outperforms state-of-the-art methods, providing a robust and scalable solution for dataset recommendation.
