摘要
目前的数字化信息资源库,衍生于传统图书馆,资源组织是以文献为单位,基于传统的倒排索引的组织形式。用户通过标题、关键词等方式进行资源检索出来的是一篇篇的文献,不能为用户提供针对具体问题的知识服务,且由于它们之间的差异性导致它们之间的资源共享难以实现。基于这些问题,文章提出了基于知识元的资源库的构建,并以教育技术学科为例做了探讨:首先总结前人的研究成果并结合我们的研究提出了教育技术学科资源分类体系;然后详细介绍了基于知识元的资源组织;最后在学科资源分类与知识元标引技术的基础上,构建了教育技术学科资源库,并对该资源库的应用做了讨论。
The current digital repositories,derives from traditional libraries,the resources organization form of which is based on inverted index and takes literature as units.In this way,uses just can retrieval information through the titles and keywords and so on,the results of which are just some literatures,not specific knowledge information for concreteissues.And based on these,this paper makes further study about constructing resource libraries with the idea of knowledge elements and takes the Educational Technology as an example.Firstly,we puts forwards the classification system on the resources of Educational Technology,and then introduces the knowledge element in detail.Following that,we construct the knowledge resource base of Educational Technology with the technology of knowledge element indexing and the classification of resources.In the end,we discuss the application of it combined with our research.
