多目标的学习者模型研究

The Research of Multi-purposes Based Learner Model

建立学习者模型几乎是所有ITS系统的普遍任务,当前的软件系统趋向于转入分布式和多代理系统,学习者模型转向零散的、由各种软件代理在特定环境下产生的模型。在“个性化课件生成子系统”中运用了这一思想,建立了基于多目标的、运行于分布式与多代理系统之上的学习者模型,该文将主要介绍这一系统的基本构成与运行结构、系统中目标的定义与组织结构,并对目标的解释、目标的生存周期等问题做了进一步的探讨。

The learner modeling is almost a widespread mission of all the ITSs.The current software systems incline to-ward distributed and multi-agent system,and learner model change into fragmental and specific model produced by many kind of software agents under the particular environment.We use this idea into“the Subsystem of creating the characterized lesson piece”,then establish a multi-purposed based leaner model under distributed and multi-agent sys-tem.This article will introduce the construction and architecture of this system,and the definition of purposes,the living period of purposes.
