Indexing complex networks for fast attributed kNN queries
Social Network Analysis and Mining, 2022 AbstractThe k nearest neighbor (kNN) query is an essential graph data-management tool used for finding relevant data entities suited to a user-specified query node. Graph indexing methods have the potential to achieve a quick kNN search response and thus are promising approaches. However, they struggle to handle large-scale attributed complex networks.
