From PIace2Vec to Multi-Scale Built-Environment Representation [PDF]
Built environments like cities, roads, communities are rich sources of urban data. Many downstream applications require comprehensive analysis like geographic information retrieval, recommender systems, geographic knowledge graphs, and in general, understanding urban spaces [28]. Points of Interests (POI), as one of the most researched aspects of urban
