Predicting Visitors Using Location-Based Social Networks

2018 19th IEEE International Conference on Mobile Data Management (MDM), 2018
Location-based social networks (LBSN) are social networks complemented with users’ location data, such as geotagged activity data. Predicting such activities finds application in marketing, recommendation systems, and logistics management. In this paper, we exploit LBSN data to predict future visitors at given locations.

Location-Based Emerging Event Detection in Social Networks

2013
This paper proposes a system for the early detection of emerging events by grouping micro-blog messages into events and using the message-mentioned locations to identify the locations of events. In our research we correlate user locations with event locations in order to identify the strong correlations between locations and events that are emerging ...

Evaluating geo-social influence in location-based social networks

Proceedings of the 21st ACM international conference on Information and knowledge management, 2012
The emerging location-based social network (LBSN) services not only allow people to maintain cyber links with their friends, but also enable them to share the events happening on them at different locations. The geo-social correlations among event participants make it possible to quantify mutual user influence for various events.
