Topical Community Detection in Event-based Social Network
Houda Khrouf, Rapha\"el Troncy

TL;DR
This paper introduces a novel method for detecting overlapping, semantically meaningful communities in event-based social networks by combining shared activity semantics with link analysis, outperforming existing methods.
Contribution
It proposes a new community detection approach that leverages user activities and semantic modularity to identify topical communities in ESBNs, including online and offline interactions.
Findings
Successfully detects semantically meaningful communities
Outperforms existing state-of-the-art methods
Effectively incorporates event categories and interaction types
Abstract
Event-based services have recently witnessed a rapid growth driving the way people explore and share information of interest. They host a huge amount of users' activities including explicit RSVP, shared photos, comments and social connections. Exploiting these activities to detect communities of similar users is a challenging problem. 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. However, such community could not be detected by most of existing methods which mainly draw on link analysis in the network. To address this problem, there is a need to capitalize on the semantics of shared objects along with the structural properties, and to generate overlapping communities rather than disjoint ones. In this paper, we propose to leverage the users' activities around events…
