2017 arXiv   pre-print
We introduce VEXUS, an interactive visualization framework for exploring user data to fulfill tasks such as finding a set of experts, forming discussion groups and analyzing collective behaviors.  ...  VEXUS combines state-of-the-art visualization techniques with appropriate indexing of user data to provide fast and relevant exploration.  ...  The user study in [5] shows an 80% satisfaction of exploring rating datasets via user groups in contrast to individuals. Fig. 1 . 1 VEXUS Architecture.  ...

In this paper, we describe UserDEV, a fullfledged user group analytics pipeline which combines discovery, exploration, and visualization of user groups, in a fully-connected fashion.  ...  The process consists of group discovery, group exploration, and group visualization. To date, user group analytics is done using separate tools which makes it fragmented and burdensome for analysts.  ...  The user data is given as input to a group discovery algorithm. VEXUS is independent of this process.  ...

2019 IEEE Transactions on Knowledge and Data Engineering  
In this survey, we discuss different approaches for each component of user group analytics, i.e., discovery, exploration, and visualization.  ...  Group analytics addresses peculiarities of user data such as noise and sparsity to enable insights.  ...  To prevent clutter, Vexus opts for visualizing only k diverse groups at each exploration iteration. FlashView. In [137] , a visualization interface is proposed for fast exploration of user groups.  ...
