FG-Index: Towards Verification-Free Query Processing on Graph Databases
Summary: FG-index builds a nested inverted-index from Frequent subGraphs to enable verification-free graph query processing, returning exact answers for frequent queries and near-exact candidates otherwise. It introduces delta-Tolerance Closed Frequent Graphs (delta-TCFGs) to bound in-memory index size, delivering orders-of-magnitude speedups over state-of-the-art indexes.
