Açık dünya politika muhakemesi için akıllı bilgi toplama

Policies play an important role in autonomous multi-agents systems where each agent aims to achieve its own goals. Policies and related mechanisms allow authority or society to regulate the actions of agents to prohibit malicious and undesirable activities. Without policies, society could be harmed by irresponsible and malicious activities of its members. On the other hand, reasoning with policies is not trivial; it requires extensive knowledge about the environment. If the knowledge is incomplete or missing, reasoning with policies may not be possible. In this thesis, we propose a proactive approach for gathering information to reason with policies. While our approach can be used in various settings, we provide two case-studies; one in social networking domain and the other in on-line advertisement domain. Through experiments we demonstrated that our approach allows high rate of success during policy reasoning when the knowledge bases is not complete.
