Approximate Graph Edit Distance Computation Combining Bipartite Matching and Exact Neighborhood Substructure Distance
Approximation de la distance d'édition entre graphes en combinant l'appariement biparti et l'appariement exact de sous structures
Résumé
Graph edit distance corresponds to a flexible graph dissim-ilarity measure. Unfortunately, its computation requires an exponential complexity according to the number of nodes of both graphs being compared. Some heuristics based on bipartite assignment algorithms have been proposed in order to approximate the graph edit distance. However , these heuristics lack of accuracy since they are based either on small patterns providing a too local information or walks whose tottering induce some bias in the edit distance calculus. In this work, we propose to extend previous heuristics by considering both less local and more accurate patterns defined as subgraphs defined around each node.
