摘要:
在 Hadoop 分布式系统上,设计并实现了一个基于 SSM 框架的评价系统,对评价系统构建的技术路线及实现方案以及基于中介真值程度度量的评价规则进行了详细阐述。 系统采用接口编程技术,对每个模块的基本功能进行抽象,可以接入并修改任意的功能模块,增强了系统的可扩展性和维护性。 系统中定义了基于中介真值程度的评价规则,分别采用距离比率函数和距离比率和函数建立了单维度测度模型和多维度综合测度模型。 除此之外,系统也可以自定义评价规则集,增强了系统的可用性。 在学生成绩评价中的应用结果表明,基于中介真值程度的评价规则,使评价结果更为科学和合理。
Abstract:
We design and implement an evaluation system on Hadoop distributed platform based on SSM framework,and discuss the tech- nical route and implementation scheme of the evaluation system construction and the evaluation rules based on the measure of medium truth degree. The system applies the interface programming technology to abstract the basic functions of each module and can add and modify any function modules,which enhances its scalability and maintainability. Furthermore,we define the evaluation rules based on the measure of medium truth degree in the system and use the distance ratio function and the distance ratio sum function to establish the meas- ure model of each dimension and the integrated measure model of multi-dimension respectively. Besides,we introduce custom evaluation rules to enhance the usability of the system. Moreover,the applicaion of student performance evaluation shows that the evaluation rules based on the measure of medium truth degree are more scientific and reasonable.
