On the correlation between topic and user behaviour in online communities
(ICWSM-16, 2016-05-20)
In the advancement of a better understanding of user behaviour on the Internet, clustering approaches are used as a means to group and categorise online communities. Although clustering approaches indicate similarity between ...
Event Analysis in Social Media Using Clustering of Heterogeneous Information Networks
(The 28th International FLAIRS Conference (AAAI Publications) (AAAI), 2015)
In this paper, we propose a novel approach for social media event finding in order to support fast access to information that users find relevant. While there are many approaches related to this problem, they mainly focus ...
