英文摘要POI configuration of a region indicates a combination of POI counts on various types inside the region. Exploring POI configurations of urban regions facilitates to understand their functionalities, vibrancy, and developments. However, current studies and applications mainly make statistics toward POI counts on various types separately, neglecting the implicit semantic relations between different types and failing to uncover POI-configuration patterns intuitively. This study proposes a novel framework for visualizing and exploring POIs on POI-type semantic space, with semantic relations of the types being considered. Firstly, using a word-embedding technique (i.e., Word2Vec), the embeddings of POI types are learned from their neighborships on geographic space. Secondly, using a dimension-reduction technique (i.e., t-SNE), all POI-type embeddings are mapped onto 2-dimensional semantic space, where related or similar types would be nearer to each other. Finally, taking the POI-type semantic space as a "base map", POI configuration of each region is rendered as a "thematic map" by POI counts on various types, which can help intuitively understand and conveniently compare urban regions. The proposed framework can be applied to any urban region and any POI data source, which provides an effective information delivery method for urban planning and POI related urban studies and applications.
