数字图书馆信息系统中引入多智能体技术,达到动态风险评估的目的。论文详细介绍了数字图书馆信息安全评估系统中多智能体的选择过程,提出了多智能体属性的转换函数,构建了基于多智能体的混合式结构,在此基础上建立了信息系统的动态风险评估模型,并简要介绍了模型中主要智能体的类型和功能,为应用多智能体技术进行数字图书馆信息安全的动态风险评估提供了理论基础。

英文摘要：

Multi-agent technology is introduced into information system of digital library to achieve the dynamic risk assessment. This paper introduces the process of choosing multi-agent in detail, presents a conversion function of multi-agent attributes in the assessment system of information security in digital library, builds a hybrid structure based on multi-agent, then constructs the model of dynamic risk assessment, and briefly describes the types and functions of the key agents. It provides a theoretical basis for applying multi-agent to the dynamic risk assessment of information security in digital library.
