Title: Location-aware search in social networks

 

Speaker: Dr. Xin Cao

 

Abstract:

 

The social networks have greatly changed the way that people interact with each other and with the world. With the proliferation of wireless communication techniques and GPS-equipped mobile devices (e.g., smart phones), nowadays users can access the social networks almost anywhere at any time. The location information plays an important role in social network applications because the geographical information brings social networks from virtual to reality, bridging the gap between the physical world and online social networking services. In this talk, I will introduce some typical search queries in such location-aware social networks as well as their solutions.
