Abstract: Provided is a method for the set similarity join, wherein each set represents a process and each token represents a process step. The process comprises a series of process steps executed in at least one source computer system. Hence, similar sets represent similar processes within a collection of processes. The method is based on a two-level signature scheme. Having indexed the sets using a first signature into inverted lists, selected lists, in particular long lists, are reindexed using a second signature. As a result, the number of candidates and thus the number of required distance calculations can be effectively reduced. Its experimental evaluation has shown that the method consistently outperforms state-of-the-art algorithms on datasets with diverging characteristics, suggesting a stable solution for a wide range of applications.
