Perceiving Beijing's "city image" across different groups based on geotagged social media data

Xia Peng, Yi Bao, Zhou Huang
2020 IEEE Access  
With the rising penetration of smart mobile devices and social media, massive data of location-related texts has been generated for a variety of urban areas.  ...  Our research shows text mining on geotagged big data for city image makes it possible to accommodate the heterogeneity of the activities of different groups of people and to understand their preferences  ...  As for big geo-data mining, the commonly used approach is spatial clustering, which could find hotspots or landmarks of the city.  ...

2012 Proceedings of the 20th ACM international conference on Multimedia - MM '12  
In addition, community-contributed data possess rich contexts such as tags, geo-locations and time stamps, which strongly correlate with user intentions and preferences.  ...  A growing number of users are contributing a huge amount of photos containing people (e.g., family, classmates, colleagues, etc.) to social media for the purpose of photo sharing and social communication  ...  We then use a mean-shift based method on geo-locations of these photos to generate the important locations in each city for the following user trip mining process.  ...
