在协作式电子学习内容管理环境中，不同学习管理系统中数据的异构性给数据共享带来了许多困难；其中一些困难是如何集成数据、为用户查询生成结果以及从异构学习管理系统中找到正确的数据。在过去的几年里，人们提出了许多电子学习系统架构；然而，与共享和整合来自不同电子学习系统的数据有关的问题却很少受到关注。考虑到这一需求，本文提出了语义数据互操作性、分布式元数据管理和基于代理的查询处理方法的解决方案，以支持来自不同电子学习系统的学习内容的交换。本文对所提出的解决方案的用户可接受性进行了实证评估，以找到用户可接受性和满意度的定性衡量标准；我们提出的解决方案获得了很高的用户满意度。
In a collaborative e-learning content management environment, the heterogeneity of data in different learning management systems presents many difficulties for data sharing; some of these difficulties are how to integrate data, produce results for user queries, and find the correct data from heterogeneous learning management systems. Over the last few years, numerous e-learning system architectures have been proposed; however, issues related to sharing and integrating data from different e-learning systems have been given less attention. Considering this need, this paper presents solutions for semantic data interoperability, distributed metadata management, and an agent-based query processing approach for supporting the exchange of learning content from different e-learning systems. The paper presents an empirical evaluation of the user acceptability of the proposed solutions to find qualitative measures of the users' acceptability and satisfaction; our proposed solutions resulted in high user satisfaction.
