文摘
- •
Hourly temporal signatures are constructed from geosocial networking point of interest (POI) check-in data.
- •
Using circular statistics, temporal signatures of POI types are compared between U.S. cities.
- •
The highest and lowest regionally variable POI types are calculated and discussed.
- •
Hierarchy homogeneity of POI types is examined and reported.
- •
POI type regional variability is compared between cities in the U.S. and Shanghai, China.
