摘要:In real lifestyles, interpersonal companies, Semantic internet and Natural techniques, social networks,and biological networks, each vertex extra by and large than now not contains important information, which may alsobe displayed by way of an arrangement of tokens or components. In this paper, a subgraph matching with set similarity(SMS2) query over a large graph database, which retrieves subgraphs that are structurally isomorphic to the querygraph, and during this time period it also satisfy the condition of vertex pair matching with the (dynamic) weighted setsimilarity. This paper designs a novel lattice-based index for data graph to efficiently process the SMS2 query, andlightweight signatures for both query and data vertices. We not only propose an efficient two-phase pruning strategybased on the index and signatures, which including set similarity pruning and structure-based pruning, and also utilizesthe unique features of both (dynamic) weighted set similarity and graph topology, but also propose an efficientdominating-set-based subgraph matching algorithm direct by a dominating set selection algorithm to achieve betterquery performance. Extensive experiments on both real as well as synthetic datasets demonstrate that our methodoutperforms state of-the-art methods by order of magnitude.
