Abstract: PROBLEM TO BE SOLVED: To provide a method for distinguishing and finding a significant cyclic pattern in event subsequence even when the pattern includes disturbance having a length up to a threshold value of prior definition. SOLUTION: A method for distinguishing a partial cyclic pattern in event sequence that includes a list of events from the event sequence in the pattern is provided. At least one pattern which is at least one subsequence in the event sequence and at least one pattern in at least one subsequence distinguishes at least one subsequence in the event sequence and at least one pattern in at least one subsequence which exceeds the minimum repetitive number in at least one subsequence and in which a distance between continuous repetitions of at least one pattern in at least one subsequence does not exceed a distance threshold value of prior definition. At least one of at least one pattern and at least one subsequence is stored.
