Abstract

In recent years, the problem of mining association rulesover frequent itemsets in transactional data has been frequentlystudied and yielded several algorithms that can findassociation rules within a limited amount of time. Alsomore complex patterns have been considered such as orderedtrees, unordered trees, or labeled graphs. Althoughsome approaches can efficiently derive all frequent subgraphsfrom a massive dataset of graphs, a subgraph orsubtree that is mathematically defined is not necessarily abetter knowledge representation. In this paper, we proposean efficient approach to discover significant rules to classifypositive and negative graph examples by estimating atight upper bound on the statistical metric. This approachabandons unimportant rules earlier in the computations,and thereby accelerates the overall performance. The performancehas been evaluated using real world datasets, andthe efficiency and effect of our approach has been confirmedwith respect to the amount of data and the computation time.
