摘要:
课程教材资源存在分散无序、知识点聚合性不足、经常变化的问题, 同时,传统的依靠人为的教材资源组织方法存在耗时费力、组织结果不易更新等问题。为了实现对课程教材资源中知识点的有效组织和利用,提出了课程知识链接描述模型,对课程资源中分散的碎片化知识进行描述,然后采用信息抽取方法,对课程教材资源中的知识点及知识点之间的关联关系进行抽取,将抽取的知识点进行标识,计算教材资源中文档与知识点间的关联,最终建立课程教材知识链接体系。 以教育心理学课程为例,建立知识链接原型系统,抽取了领域内概念 435 个,并对各文本内容进行了标注,实现了该方法的应用。 方法在不改变现有的资源组织架构的前提下,实现知识点与知识点、知识点与文档的关联,具有很强的适应性和可用性。
Abstract:
There are some problems in the resources of curriculum teaching materials,such as scattered disorder,insufficient aggregation of knowledge points and frequent changes. At the same time,the traditional method of relying on artificial teaching material resource is time-consuming and laborious? ?with the organization result not easy to update. In order to realize the effective organization and utilization of knowledge points in curriculum textbook resources, a course knowledge’s link description model is proposed, and the scattered fragmentation knowledge in curriculum resources is described. Then the relationship between knowledge points and knowledge points in the course textbook resources are extracted by the information extraction method.The extracted knowledge points are identified,the rela-tionship between Chinese file and knowledge points of textbook resources is calculat- ed,? and finally the knowledge’s link system of course textbook is established. Taking the course of educational psychology as an example, the prototype system of knowledge link is established,435 concepts in the field are extracted,and the contents of each text are labeled,realizing the application of this method.Without changing the existing resource organization architecture, this method realizes the relationship between knowledge points and knowledge points,knowledge points and documents,which has strong adaptability and usability.
