Terrorist organizations are not completely independent. However, they frequently interact with each other. Detecting the terrorist organizations cooperation behavior is quite helpful to develop effective counter-terrorism strategy. Computational intelligence techniques used to design effective data analysis method offer a way for monitoring covert terrorism activities. In this paper, we propose a cooperation behavior analysis solution based on Adaboost classifier to identify. The traditional social network method is extended by employing computational intelligence technique to generate automated analysis capacity. Variant network properties are combined by using Adaboost classification to improve the robustness of changes identification of cooperation behaviors. Finally, the method is applied to an open source dataset. The result indicates that Adaboost classifier can take advantage of multi-properties and is more robust than only using single property. It shows the potential of developing an effective method by using computational intelligence techniques in the field of public security.
