Threat Level Assessment Based on Object-Oriented Probabilistic Relational Model

Considering some of the limitations of Bayesian Network(BN) in modeling complex domains,the Object-Oriented Probabilistic Relational Model(OPRM) was analyzed.Then an algorithm for generating Bayesian Networks from the knowledge base of OPRM was proposed.A model for threat level assessment was developed and the result of threat level assessment was given.Simulation results demonstrate that the proposed method is effective and more powerful in modeling complex objects than Bayesian Networks.
