2013 Frontiers of Computer Science  
Then we propose a machine learning formula for predicting co-occurrence based on the social ties and habits similarities.  ...  Location-based social network (LBSN) is at the forefront of emerging trends in social network services (SNS) since the users in LBSN are allowed to "check-in" the places (locations) when they visit them  ...  Conclusion In this paper, we present a study of exploring spatio-temporal features of user's activities to predict co-occurrence in a location-based social network, Gowalla.  ...

Academic failures and co-location social networks in campus

Shan Lu, Jichang Zhao, Huiwen Wang
2022 EPJ Data Science  
This paper focuses on the associations between academic failures, that defined by not passing course exams, and campus social networks based on students' co-location occurrences.  ...  Additionally, we show that messages reflected in co-location social networks and behavioral activities indeed help predict failures and the network snapshot at mid-term offers competent prediction power  ...  The limitation of this study lies in the fact the co-location social networks are inferred based on high-frequency co-occurrences in smart-card system.  ...

EBM

Huy Pham, Cyrus Shahabi, Yan Liu
2013 Proceedings of the 2013 international conference on Management of data - SIGMOD '13  
We examine two independent ways: diversity and weighted frequency, through which co-occurrences contribute to social strength.  ...  In this paper, we are interested in inferring these social connections by analyzing people's location information, which is useful in a variety of application domains from sales and marketing to intelligence  ...  (e.g., location popularity). • We evaluated EBM using a large real-world dataset collected by a location-based social network called Gowalla.  ...

Exploring homophily in demographics and academic performance using spatial-temporal student networks

Quan Nguyen, Oleksandra Poquet, Christopher Brooks, Warren Li
2020 Educational Data Mining  
However, a large part of students' social connections through day-to-day oncampus encounters has remained underexplored.  ...  A tie in the spatialtemporal network was inferred when two individuals connected to the same WiFi access point at the same time intervals at the 'beyond chance' frequency.  ...  In line with previous research on location-based networks [15, 16] , social ties between WiFi users can be inferred from spatial and temporal co-occurrences (i.e. two users connected to the same WiFi  ...
