As smart phones, global positioning systems, and Web 2.0 technologies become prevalent, mobile social networks (MSN), including location based social networks, are getting popular, e.g., Foursquare, BrightKite, Jiepang, Facebook, Google+, Flickr, Wechat all offer location sharing services. MSN bridge the physical and virtual worlds by enabling anytime anywhere social interaction and geotagging any user generated content. It is believed that various application domains will be benefited from analyzing the data from MSN, such as business services, health care, disaster management, smart cities, etc.. However, since they reflect the daily social lives of billions of people, MSN data are not only of vast amount, but also with characteristics distinguished from general big data: 1) complex network structures from the social dimension; 2) sparse or coarse trajectories from the spatial dimension; 3) subjective bias from human factors. Therefore it is imperative to develop sophisticated and scalable analyzing techniques for extracting meaningful information from MSN Data.

To address these concerns, the workshop BigMSN 2013 is intended to provide a forum for researchers to present their researches related to big data analytics in MSN. We solicit technical papers of topics including but not limited to:
* Location estimation / prediction from MSN data
* User / group mobility modeling
* Activity / emotion / opinion recognition from MSN data
* Data mining / machine learning / pattern recognition in MSN
* Algorithms for mobile / crowd / participatory sensing
* Social structure and community detection in MSN
* Dynamics and evolution of MSN
* Storing and querying of large scale graph / spatial data
* Location based personalized search / recommendation
* Energy / bandwidth / time efficient strategy for MSN
* Security, privacy, trust and reputation in MSN
* Software architecture for MSN data analytics lifecycle
* Visualization of MSN data
* Innovative location-based services and applications
* User studies and experiences
