摘要： 针对目前e-learning环境下测试评估系统在资源共享和范围划分灵活等方面的问题，提出了一个基于对象本体的测试评估系统模型，该模型需要建立基于本体的测试对象库，然后对用户输入的测试要求进行分词、本体提取和测试对象定位，并根据用户的个人信息提供个性化的测试，基于该模型建立的测试评估系统在资源共享、资源重用以及测试评估范围的灵活划分与试题的灵活选择方面具有较好的效果。

Abstract: To improve performance of resource share and scope clear-cut in test and evaluation system in e-learning environment, a model of test and evaluation system is put forward based on objects and ontology. In this model, a test objects base is built based on ontology, and then the test request of user is segmented, ontology extracted and test objects found, and an individual test is provided based on user’s private information. In the model, the effect of share, reuse of resource and scope clear-cut of the test and evaluation and flxibile selection of question are good.
