A paper on "Identifying Spatial Buddies to Track Lost Items" by Eyuphan Bulut and Boleslaw K. Szymanski has been accepted for 2017 Workshop on SocialSens
The authors study the tracking of lost objects through the collaboration among users. They analyze the visit patterns of users at the same locations and develop a metric that quantifies for each user the potential benefit of others in terms of their capability of finding that user’s lost objects. Depending on the predicted benefits, each user’s preference list of other users is formed and then utilized to identify the space buddies who can best track her lost items. The proposed system was applied to two different location based social network datasets and showed its effectiveness in different settings.
