I investigate how people interact with geographic places through digital platforms, and how these interactions can be modelled to enhance personalization and understanding. This includes:
- Creating spatio-semantic user profiles from check-ins, tags, and annotations on LBSNs like Foursquare
- Measuring user similarity over time, space, and semantics
- Enhancing location and content recommendation systems with enriched user data
- Exploring privacy-aware user modelling and activity-based reasoning
Emerging directions:
Place Profiling,
Place Affordance,
Spatiotemporal Modelling and Reasoning,
Privacy-aware LBSNs
