2009 International Workshop on Location Based Social Networks (LBSN’09)
http://research.microsoft.com/en-us/um/people/xingx/LBSN2009.htm

Nov. 3, 2009, Seattle, WA, USA
Held in conjunction with the 17th ACM SIGSPATIAL International Conference on
Advances in Geographic Information Systems

Aim and Scope
Social networking services have become extremely popular in recent years,
especially for young people. However, they are still rooted in the virtual
world. People usually need to sit behind a desktop computer to upload
photos, write blogs and communicate with friends. The development of
wireless networks and location sensing technologies have made it easier to
track and share personal location information on the fly. By adding a
location dimension, we can bring social networking back from the virtual
world into real life and allow real-life experiences to be shared in a more
convenient way. We define Location Based Social Networks (LBSN) as social
network services where people can track and share location related
information with each other, via either mobile or desktop computers. As
location is one of the most important aspects for people’s everyday lives, a
lot of novel application scenarios can be supported by LBSN. For example, we
can collect and share more trustworthy location recommendations within LBSN
and use them to rank interesting locations, discover new places, people and
activities.

The objective of this workshop is to provide a single forum for researchers
and technologists to discuss the state-of-the-art, present their
contributions, and set future directions in emerging innovative research for
location based social networks.

Topics of Interest
Topics of interest include, but are not limited to the following aspects of
location based social networks:
?             Spatial data mining and knowledge discovery
?             Personal location/trajectory data mining
?             Spatial query log mining
?             Geo-tagged multimedia mining
?             Opinion mining for location related information
?             Spatial data indexing
?             Hybrid index for spatial, textual and multimedia data
?             Index for moving objects
?             Location based social network analysis
?             Geographical information extraction and retrieval
?             Spatial data acquisition and pre-processing
?             Spatial data visualization and computer human interface
?             Location privacy, data sharing and security
?             Navigation and traffic prediction
?             Systems, architectures and middleware

Submission
We seek three kinds of submissions related to location based social
networks:
?             Full research papers – up to 8 pages
?             Vision papers and short technical papers - up to 4 pages
?             Demo papers – up to 2 pages

Authors are invited to submit full, original, unpublished research papers
that are not being considered for publication in any other forum.
Manuscripts should be submitted in PDF format and formatted using the ACM
camera-ready templates available at:
http://www.acm.org/sigs/pubs/proceed/template.html

Papers must be submitted electronically, via the submission website (
http://www.easychair.org/conferences/?conf=lbsn2009) on or before the
submission deadline. All accepted papers will be included in the ACM digital
library.
