Graph pattern matching: From intractable to polynomial time
Graph pattern matching is typically defined in terms of subgraph isomorphism, which makes
it an np-complete problem. Moreover, it requires bijective functions, which are often too …

Query preserving graph compression
It is common to find graphs with millions of nodes and billions of edges in, eg, social networks.
Queries on such graphs are often prohibitively expensive. These motivate us to propose …
