Acting on time-critical events by processing ever growing social media or news streams is a major technical challenge. Many of these data sources can be modeled as multi-relational graphs. Continuous queries or techniques to search for rare events that ...

For very large dynamic networks, monitoring the behavior of a subset of agents provides an efficient framework for detecting changes in network topology. For example, in mobile caller networks with millions of subscribers, we would like to monitor the ...

An important way of summarizing a bipartite graph is to give a set of (quasi-) bicliques that contain (almost) all of its edges. These quasi-bicliques are somewhat similar to clustering of the nodes, giving sets of similar nodes. Unlike clustering, ...

An increasingly important challenge in network analysis is efficient detection and tracking of communities in dynamic networks for which changes arrive as a stream. There is a need for algorithms that can incrementally update and monitor communities ...
