Community Detection in Social Network using Temporal Data [article]

Victor Stany Rozario, A.Z.M. Ehtesham Chowdhury, Muhammad Sarwar Jahan Morshed
2019 arXiv   pre-print
Social networks facilitate the social space where actors or the users have ties among them. The ties and their patterns are based on their life styles and communication.  ...  Similarly, in online social media networks like Facebook, Twitter, Myspace etc., multiple users belong to multiple specific communities.  ...  Overlapping communities can be depicted as overlapping clusters [5] on complex social network. The detection of the clusters based on the betweenness are the centrality measure [6] .  ...

Topical Community Detection in Event-based Social Network [article]

Houda Khrouf, Raphaël Troncy
2018 arXiv   pre-print
In reality, a community in event-based social network (ESBN) is a group of users not only sharing common events and friends, but also having similar topical interests.  ...  In this paper, we propose to leverage the users' activities around events with the aim to detect communities based on topical clustering and link analysis that maximize a new form of semantic modularity  ...  Community detection is considered as a major topic for analyzing social networks which has recently received a great attention.  ...
