[Qgis-community-team] Call for participation: 3rd ACM SIGSPATIAL International Workshop on Location-Based Social Networks (LBSN 2011)

[Wei Ding]

3rd ACM SIGSPATIAL International Workshop on Location-Based Social Networks
(LBSN 2011)
November 1, 2011 - Chicago, Illinois, USA
Held in conjunction with the 19th ACM SIGSPATIAL GIS 2011

General Chair:
Christian S. Jensen, Aarhus University, Denmark
Wang-Chien Lee, Pennsylvania State University, USA
Program Chair:
Mohamed F. Mokbel, University of Minnesota, USA
Yu Zheng, Microsoft Research Asia, China


Aims and Scope:

Social networks have been prevalent on the Internet and have become a
hot research topic attracting many professionals from a variety of
fields. By adding a location dimension, we can bring online social
networks back to the physical world and share our real-life
experiences in the virtual world conveniently. In location Based
Social Networks (LBSN), people cannot only track and share
location-related information with each other via either mobile devices
or desktop computers, but also leverage collaborative social knowledge
learned from user-generated and location-related content. As location
is one of the most important properties in people's everyday lives,
LBSN will bridge the gap between online societies and the physical
world and enable a lot of novel applications changing the way we live,
such as travel planning, location/friend recommendations, community
discovery, human mobility modeling and user activity analysis. The
technology derived from LBSN, e.g., location trajectory mining and
retrieval, can also be applied to a multitude of other research areas
including biology, sociology, geography, and climatology, etc. The
objective of this workshop is to provide professionals, researchers,
and technologists with a single forum where they can discuss and share
the state-of-the-art of LBSN development and applications, present
their ideas and contributions, and set future directions in emerging
innovative research for location based social networks.
