Visual querying of large multilayer graphs

Abstract

Many real world data can be represented by a network with a set of nodes linked each other by multiple relations. Such a rich graph is called multilayer graph. In this demo, we present a tool for Visual Querying of Large Multilayer Graphs that allows to visually draw the query, retrieve result patterns and finally navigate and browse the results considering the original multilayer graph database. Our approach does not only provide a graphical user interface for the graph engine but the query processing is fully integrated.

“…An intersecting functionality provided by some graph querying systems is to assist the user when designing a query by suggesting additional data. For instance, Yi et al 20 and Cuenca et al 21 described systems in which additional edges and nodes are proposed to refine the current query in regard of the whole graph dataset. In EpidVis, [R3] consists of integrating external information to the list of keywords used to construct the queries.…”
