Graph similarity using tree edit distance
Web""" Functions measuring similarity using graph edit distance. The graph edit distance is the number of edge/node changes needed to make two graphs isomorphic. The default algorithm/implementation is sub-optimal for some graphs. The problem of finding the exact Graph Edit Distance (GED) is NP-hard so it is often slow. Webmeasuring inter-graph node similarity with edit distance, called NED. In our measure, two inter-graph nodes are compared according to their neighborhood topological struc-tures …

WebGraph similarity learning, which measures the similarities between a pair of graph-structured objects, lies at the core of various machine learning tasks such as graph classification, similarity search, etc. ... Approximate graph edit distance computation by means of bipartite graph matching. Image and Vision computing, Vol. 27, 7 (2009), 950 ... In mathematics and computer science, graph edit distance (GED) is a measure of similarity (or dissimilarity) between two graphs. The concept of graph edit distance was first formalized mathematically by Alberto Sanfeliu and King-Sun Fu in 1983. A major application of graph edit distance is in inexact graph matching, such as error-tolerant pattern recognition in machine learning. The graph edit distance between two graphs is related to the string edit distance between strings. …

WebEdit distance. In computational linguistics and computer science, edit distance is a string metric, i.e. a way of quantifying how dissimilar two strings (e.g., words) are to one another, that is measured by counting the minimum number of operations required to transform one string into the other. Edit distances find applications in natural ... WebGraph similarity search is to retrieve all graphs from a graph data- base whose graph edit distance (GED) to a query graph is within a given threshold. As GED computation is NP-hard, existing so- lutions adopt theltering-and-verication framework, where the main focus is on theltering phase to reduce the number of GED verications.
