Abstract:
Methods and apparatus are provided for incremental frequent subgraph mining on dynamic graphs. An exemplary subgraph mining method comprises maintaining a set of embeddings comprising matching embeddings of a given subgraph in an input graph; maintaining a first fringe set of subgraphs comprising subgraphs substantially on a fringe of frequent subgraphs in the input graph that satisfy a predefined support threshold; maintaining a second fringe set of subgraphs comprising subgraphs substantially on a fringe of infrequent subgraphs in the input graph that do not satisfy the predefined support threshold; for an edge addition, checking a support of the subgraphs in the second fringe set based on the set of the embeddings and searching for new embeddings created by the edge addition; and for an edge deletion, removing obsolete embeddings that comprise the deleted edge from the first fringe set based on the set of embeddings.
