Abstract: Process mining techniques aim to improve and maintain the business process via analyzing process model, which is derived based on the event log of information system. At present, many business processes interact with each other in a modular way. A lot of algorithms have been proposed, the processing of multi module still has limitations. A business mining method is proposed based on feature nets and module nets. According to the log, features are divided into different modules. On this basis, a feature net with features interactive between module and modular nets with features interactive in the module will be gained. Then modular nets and feature nets are fused, and a complete model will be obtained. Finally, the feasibility of the algorithm is illustrated through an example of online shopping.
