Abstract: With the rapid development of information technology and network technology and their widespread use in military field,networking information-centric system of systems comes into being.The networking information-centric system of systems is dominated by information,its main manifestation is the information activity process.The rationality and efficiency of the information activity process directly affect the operational effectiveness of information in the combat system.The use of process mi-ning technology to discover information activity process models from information activity event logs can provide effective support for modelling,testing and enhancement of information activity processes.Simply filtering noise in logs through event frequency analysis can easily lead to the loss of valid low-frequency paths and reduce the accuracy of the mined information activity processes.Combining the special characteristics of military information activities and the effectiveness characteristics of information transfer,a structure aggregation degree based effective low frequency path mining algorithm is proposed.Simulation analysis shows that the method can successfully separate log noise and effective low frequency paths,which is important for mining real and effective information processes.
