RTSKG: A Knowledge Graph Dataset for Rail Transit Stations

Researchers have introduced the Rail Transit Station Knowledge Graph (RTSKG), a dataset designed to model spatial and semantic interactions among urban entities for city-level rail transit station tasks. The dataset integrates heterogeneous urban data, including rail transit stations, road segments, and points of interest, under a unified schema. It is available as Linked Data at https://w3. The work addresses the limitation of current studies that often neglect complex interactions among urban entities in data organization. RTSKG aims to benefit tasks such as ridership prediction by providing a structured representation of urban relationships. The dataset is described in a paper on arXiv (arXiv:2608.11080v1).
