A Process Mining Based Service Composition Approach for Mobile Information Systems

Algorithm 1

Preprocessing—preprocessing logs for process mining by steps of removing invalid records, eliminating similar request in a short time, picking the successful request and deleting others, connecting service with events, and dividing the events into traces, according to time duration.
