Information quality assurance despite uncertainty can be investigated in the context of soft security where an agent maintains trustworthiness evaluations of its information sources to assist in the evaluation of incoming information quality. Dependency inherently exists in a system where agents do not have self-sufficient sensing or data collection capabilities. In other words, an agent requires information from others to achieve its goals. Finding the best partners to form an information sharing network using the notion of trustworthiness can be triggered by dependency adaptation. This research experimentally demonstrates that dependency adaptation can lead a system to form an information sharing network which results in high efficiency and information quality.
