The GraphTempo Framework for Exploring the Evolution of a Graph through Pattern Aggregation

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…

On Graph Deltas for Historical Queries

Georgia Koloniari, Dimitris Souravlias, Evaggelia Pitoura

In this paper, we address the problem of evaluating historical queries on graphs. To this end, we investigate the use of graph deltas, i.e., a log of time-annotated graph operation…
