Query: Mining Non-Redundant Local Process Models From Sequence Databases   Sequential pattern mining techniques extract patterns corresponding to
frequent subsequences from a sequence database. A practical limitation of these
techniques is that they overload the user with too many patterns. Local Process
Model (LPM) mining is an alternative approach coming from the field of process
mining. While in traditional sequential pattern mining, a pattern describes one
subsequence, an LPM captures a set of subsequences. Also, while traditional
sequential patterns only match subsequences that are observed in the sequence
database, an LPM may capture subsequences that are not explicitly observed, but
that are related to observed subsequences. In other words, LPMs generalize the
behavior observed in the sequence database. These properties make it possible
for a set of LPMs to cover the behavior of a much larger set of sequential
patterns. Yet, existing LPM mining techniques still suffer from the pattern
explosion problem because they produce sets of redundant LPMs. In this paper,
we propose several heuristics to mine a set of non-redundant LPMs either from a
set of redundant LPMs or from a set of sequential patterns. We empirically
compare the proposed heuristics between them and against existing (local)
process mining techniques in terms of coverage, redundancy, and complexity of
the produced sets of LPMs.
