gSpan is a popular algorithm for discovering frequent subgraphs in a graph database. It was proposed by Yan et al. (2002). See more The output is the set of all subgraphs that appear in at least minsup percent of the graphs of the input graph database, and their support values. … See more The input is a set of labeled connected graphs and a threshold named minsup(a value between 0 and 100 %). Moreover, a few optional parameters can be set, which will be described further down this page. To explain the input … See more This implementation of gSpan also has four optional parameters: 1. maxNumberOfEdges: the maximum number of edges that frequent subgraphs should contain.
