A large-scale location-based social network to understanding the impact of human geo-social interaction patterns on vaccination strategies in an urbanized area. [PDF]
Comput Environ Urban Syst, 2018 Cities play an important role in fostering and amplifying the transmission of airborne diseases (e.g., influenza) because of dense human contacts. Before an outbreak of airborne diseases within a city, how to determine an appropriate containment area for

A Fine-Grained Indoor Location-Based Social Network [PDF]
IEEE Transactions on Mobile Computing, 2016 Existing Location-based social networks (LBSNs), e.g., Foursquare, depend mainly on GPS or cellular-based localization to infer users’ locations. However, GPS is unavailable indoors and cellular-based localization provides coarse-grained accuracy.

Social user geolocation based on K-medoids and Gaussian Kernel graph attention network [PDF]
Scientific ReportsAccurate user location information is crucial for many location-based network services. However, existing social user geolocation methods using fixed-grid partitioning fail to accurately locate users in rural areas. Additionally, these methods ignore the

International Journal of Distributed Sensor Networks, 2012 This paper presents an adaptive e-learning system which supports collaborative learning based on a location-based social network and semantic modeling. In the system, a social network among e-learning learners is dynamically constructed on the basis of ...

Analysis of a Location-Based Social Network
2009 International Conference on Computational Science and Engineering, 2009 Location-based Social Networks (LSNs) allow users to see where their friends are, to search location-tagged contentwithin their social graph, and to meet others nearby. The recent availability of open mobile platforms, such as Apple iPhones and Google Android phones, makes LSNs much more accessible to mobile users.To study how users share their ...

The Detection of Anomalous Users in Location-Based Social Networks by Using Graph Rules [PDF]
مدیریت مهندسی و رایانش نرم, 2022 An analysis of social networks is necessary to detect anomalous users, due to the popularity of these networks. This paper aims to detect anomalous users in location based social networks. For this purpose, an ego graph is computed for each user, and the
