Welcome to LBSN 2012!
5th ACM SIGSPATIAL
International Workshop on Location-Based Social Networks (LBSN)
2012
November 6th, 2012,
Redondo Beach, CA, USA
Social networks and social media are 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 and media back
to the physical world and share our real-life experiences in the virtual world
conveniently. In Location Based Social Networks (LBSN), people can not only track
and share location-related information with each other via mobile devices or
desktop computers, but can 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 bridge the gap between online
societies and the physical world, enabling novel applications that have the potential
to change 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 in LBSN development
and application, present their ideas and contributions, and set the future direction of
LBSN research. In this fifth offering of the workshop, we would like to broaden the focus
to include location based social media more generally. Social media platforms such as Twitter
represent a rich source of information about individual and group behavior and much of this
data has location information associated with it, either explicitly or implicitly.
Topics
- Spatial and spatio-temporal data mining in user-centric scenarios
- Moving object tracking, indexing and retrieval for social applications
- Trajectory compressing and simplification
- Trajectory mining, pattern recognition, and knowledge discovery
- Location privacy and security
- Uncertainty of location and trajectory in modeling, inference, and querying
- Activity recognition and sensing for social applications
- Location identification from sensor data for social applications
- User behavior modeling using physical sensor data
- Semantic meaning and knowledge discovery from location-related data
- User similarity computing based on location-related information
- Social structure detection from location-related data
- Location and friend recommendations
- Hot spots, significant places, and interesting locations detection
- Location-tagged media sharing and mining
- Human-computer interaction in location-based social networks
- Mobile and ubiquitous computing for location-based social networks
- Information retrieval in location-based social networks
Submission Instructions
Submitted papers must not substantially overlap with papers
that have been published or that are simultaneously submitted to a
journal or a conference with proceedings. Submitted papers can be of two
types:
- Regular Research Papers: these papers should report
original research results or significant case studies. They should be at
most 8 pages.
- Position Papers: these papers should report novel
research directions or identify challenging problems. They should be at
most 4 pages.
Manuscripts (both research and position papers) should be
submitted in PDF format according to the ACM camera-ready
templates available at:
http://www.acm.org/sigs/pubs/proceed/template.html
Papers must be
electronically submitted at the following address:
http://www.easychair.org/conferences/?conf=lbsn2012
At least one author
of each accepted paper must register for the
workshop. The workshop proceedings will also be part of the ACM Digital
Library.
