TL;DR
SGAP-Place provides an approach for incorporating higher-order social meanings into place representation and indicates that social semantics can serve as an explicit and useful information layer in place representation.
People search for urban outdoor places not only by category or function, but also by what activities a place can support and how it is perceived. Existing geospatial retrieval remains largely POIcentric and metadata-driven, making it difficult to satisfy openended, affective, or activity-oriented needs. We present Plac...
MoRAX, a lightweight framework for augmenting geospatial embeddings with functional structure derived from human mobility, is introduced and transfer results across countries further demonstrate that modulation conditioned on mobility flows provides a general mechanism for grounding geospatial foundations in the human...
Mobility Stream-Structure Synergy (MoSS) is proposed, which derives complementary views from mobility data: a Sequence view that preserves each region's hourly inflow/outflow profile, and a Structure view that captures how regional connectivity emerges, persists, and dissolves over time.
Geospatial representation learning from satellite imagery is a fundamental problem for large-scale urban analysis and real-world applications. Despite recent advances, current methods struggle with cross-region generalization and semantic interpretability due to their reliance on region-specific auxiliary data and the...
This work proposes UGE, a two-stage training strategy that progressively and stably aligns images, text, and spatial structures by combining instruction-guided contrastive learning with graph-based spatial encoding, and introduces \dataset, a spatially grounded dataset that anchors street-view images to structured spat...
SeMoFlow is proposed, a Semantic human Mobility generation framework based on latent Flow matching that achieves higher trajectory fidelity than existing baselines, preserves city-specific mobility motifs, and supports both joint multi-city generation and effective cross-city transfer.
