针对目前计算机自适应测试系统在远程网络测试中存在的局限性,提出了基于XML的在线自适应测试系统模型。通过题目自反应理论建立计算机自适应测试模型,并提出了一种约束试卷生成的参数模型,利用增量学习算法设计了组卷策略,解决了远程网络自适应测试系统中计算量大、易造成网络交互阻塞瓶颈等技术问题。最后给出了系统的设计模型,并描述了该系统的实现过程。
Against the limitations of computer adaptive test(CAT) in remote network test, this paper constructed a new CAT model based on XML. Adopted XML with the relation data model mapping mode, put forward a restriction examination paper created parameter model, and designed group paper strategy using incremental learning arithmetic. This work solved the net flow bottleneck of CAT. Lastly it gave the system design and described the process of implement.
