WebGraph similarity search is to retrieve all graphs from a graph data- base whose graph edit distance (GED) to a query graph is within a given threshold. As GED computation is NP-hard, existing so- lutions adopt theltering-and-verication framework, where the main focus is on theltering phase to reduce the number of GED verications.
