【摘要】：大数据时代层出不穷的各式各样教育资源开始不断冲击着学习者的眼球。学习者如何在海量的教育资源中快速、有效地获取有价值的数据是一件非常困难的事情。所以,如何为学习者更好的组织并推送教育资源成了亟待解决的关键问题。基于此,本文重点研究web2.0环境下教育资源的存储、组织及推送策略。具体包括:(1)论文所需的相关理论和技术的探讨。(2)分析现有的典型教育资源组织方法的优缺点,并对典型模型中资源的颗粒度、语义聚合度和层次度三个方面的研究结果进行归纳和总结。(3)在原有典型模型的基础上提出一个新的教育资源动态组织模型,该模型的组织策略采用了带有多属性的特征描述方式,同时遵循知识之间的上下位概念关系,并具有多维度多层次特征。讨论了模型中每个部分的实现过程,并通过与其他组织模型的对比分析验证了新模型的有效性。(4)采用XML技术生成RSS源,为学习者提供RSS推送策略服务,并通过ASP.NET语言实现RSS推送功能,完成资源在物理层面的二次重组。在推送服务中改进了RSS推送策略,过滤掉了不同来源的相同内容的重复推送,减少了学习者对重复教育资源的筛选工作,有效的提高了对教育资源的利用率。
[Abstract]:The endless variety of educational resources in the era of big data began to hit the eye of the learners. It is a very difficult thing for learners to obtain valuable data quickly and effectively in massive educational resources. Therefore, how to better organize and push educational resources for learners has become a key problem to be solved. Based on this, this paper focuses on the storage, organization and push strategy of educational resources under the environment of Web2.0. It includes: (1) the discussion of the relevant theories and techniques needed in the paper. (2) analyze the advantages and disadvantages of the existing typical organization methods of educational resources, and summarize and summarize the research results of three aspects: particle size, semantic cohesion and hierarchy of resources in typical models. (3) a new dynamic organization model of educational resources is put forward on the basis of the original model. The organizational strategy of the model is characterized by multiple attributes, followed by the relationship between knowledge and the upper and lower concepts, and has multiple dimensions and multi-level characteristics. The implementation of each part of the model is discussed, and the validity of the new model is verified by comparison with other organization models. (4) use XML technology to generate RSS source, provide RSS push strategy service for learners, and realize RSS pushing function through ASP.NET language, and complete the two reorganization of resources at physical level. In the push service, we improved the RSS push strategy, filtering out the repeated push of the same content from different sources, reducing the learners' screening work for repeated education resources, and effectively improving the utilization of educational resources.
