Evangelia Tsoukanara, Georgia Koloniari, Evaggelia Pitoura +1
When the focus is on the relationships or interactions between entities, graphs offer an intuitive model for many real-world data. Such graphs are usually large and change over tim…
Skyline-based exploration of temporal property graphs
Evangelia Tsoukanara, Georgia Koloniari, Evaggelia Pitoura
In this paper, we focus on temporal property graphs, that is, property graphs whose labeled nodes and edges as well as the values of the properties associated with them may change…
TempoGRAPHer: Aggregation Based Temporal Graph Exploration
Evangelia Tsoukanara, Georgia Koloniari, Evaggelia Pitoura
Graphs offer a generic abstraction for modeling entities, and the interactions and relationships between them. Most real world graphs, such as social and cooperation networks evolv…
Should I Stay or Should I Go: Predicting Changes in Cluster Membership
Evangelia Tsoukanara, Georgia Koloniari, Evaggelia Pitoura
Most research on predicting community evolution focuses on changes in the states of communities. Instead, we focus on individual nodes and define the novel problem of predicting wh…
