11. The method of claim 10 , wherein a set of candidate temporal relations, for which a total number of supporting customers is a preset minimum support or more, among one or more candidate temporal relations, is determined to be a frequent temporal relation set.
11. The method of claim 10 , wherein a set of candidate temporal relations, for which a total number of supporting customers is a preset minimum support or more, among one or more candidate temporal relations, is determined to be a frequent temporal relation set. 13. The method of claim 11 , wherein the temporal relation rule is derived from the frequent temporal relations using the following Equation: 
 TR( e 1 ,e 2 ,e 3 )═R 1 (e 1 ,e 2 )|supp(R 1 ) ^ R 2 (e 2 ,e 3 ) |supp(R 2 ) ^R 3 (e 1 ,e 3 )|supp(R 3 ) (where e 1 , e 2 , and e 3 : event types, TR: temporal relation rule, R 1 , R 2 , and R 3 : candidate temporal relations, supp: support of candidate temporal relation).
