摘　　要：在结构化知识图的基础上,根据不同学生的学习状态,提出了网络学习环境的个性化学习内容生成算法.在课程本体知识结构图的基础上,经过动态评估学习过程而形成基于不同学生的个性化知识结构图,结合其子空间及有向无环图的拓扑排序方法,设计并实现了基于目标知识点的学习路径和个性化学习内容生成算法,以及在线学习环境中个性化学习内容生成机制.经网络学习课程实例验证表明,该算法可以满足学生个性化学习的需求.Individual learning content retrieved from knowledge domain repositories for different learners is necessary in e-leaning environment for independent learning. This paper proposed an algorithm to produce individual learning content based on structural knowledge graph（SKG）.The ontology domain structural graph of course is the foundation.Individual SKG is a result from course＇s SKG during students＇ learning process.A subspace of SKG is come out after learner choosing an object point to learn.The learning knowledge points and the relative learning objects are assembled through the topological sort algorithm and the individual SKG.
