class of algorithms represents molecules as graphs and then searches for frequent subgraphs in the molecule database. All known graph based data mining algorithms rely on one of the two well-known frequent item-set mining algorithms, Apriori 1 or Eclat 11. Examples are MoFa 2, FSG 6, 0-7803-8566-7/04/$20.00 c 2004 IEEE.

2 Distinctive Ideas of MoFa, gSpan, FFSM, and Gaston All four fragment miners work on general, undirected graphs with labeled nodes and edges. They all are restricted to nding connected subgraphs and traverse the lattice as mentioned before in depth-rst order. MoFa (Molecule Fragment Miner, by Borgelt and Berthold in 2002 9) has
MoFa (Molecule Fragment Miner, by Borgelt and Berthold in 2002 9) has been targeted towards molecular databases, but it can also be used for arbitrary graphs. MoFa stores all embeddings (both nodes and edges). Extension is re-stricted to those fragments, that actually appear in the database. Isomorphism

Sep 03, 2018 MoFa The Molecular Substructure Miner (MoSS)/Molecular Fragment Miner (MoFa) 34 is an algorithm inspired by eclat 45 , designed for finding frequent fragments (frequent connected subgraphs) in molecular data. It uses adjacency matrices for graph representation and traverses the search space in a DFS manner.

12 algorithms, for mining all frequent connected subgraphs (FCSs). These algorithms are similar to the original Apriori algorithm 1 for mining frequent itemsets. To avoid overheads of the earlier algorithms, new pattern growth based algorithms such as gSpan 24, 25, MoFa 3, FFSM 11, and Gaston 17 were developed.

Canonical Forms for Frequent Graph Mining 3 is less obvious. For this, the nodes of the graph must be numbered (or more generally endowed with unique labels), because we need a way to specify the source and the destination node of an edge. Unfortunately, dierent ways of numbering the nodes of a graph yield dierent code words, because they

Dec 01, 2016 Big graph mining is an important research area and it has attracted considerable attention. It allows to process, analyze, and extract meaningful information from large amounts of graph data. Big graph mining has been highly motivated not only by the tremendously increasing size of graphs but also by its huge number of applications.
