摘　　要：探讨了基于本体技术的数字学习资源标注方法,并以特定图像数据的管理为例。图像数据需由外部的描述机制使其具有类似文字性数据的特性可供检索,从而方便数字资源查询系统的运作,然而现阶段的标注方法还无法表达与资源对应的语意概念,因此研究希望利用本体技术改进非文字型数据的注释数据定义方式,从而协助提供知识型的图像标注。之后以《数据结构》中所涉及的图像为例,进行应用上的验证。从结果来看,研究将有助于太原高职高专院校构建出基于本体的数字学习标准的教材内容管理系统。This study investigated the ontology-based technology,digital learning resources for annotation mechanism,and to the management of image data as an example.Image data required by the external description of the mechanism to make it similar to the characteristics of text data can be searched,thereby facilitating the operation of digital resources query system,but in the current annotation of resources are still unable to express the corresponding semantic concept,so this study hope to use ontology Note the definition of technological improvements of data to assist in providing knowledge-based approach to the note on the image.After the ＂Data Structure＂ of this chapter,for example,for application verification.From the results,this study will contribute to Taiyuan in higher vocational colleges to build a standards-based digital learning materials ONTOLOGY content management system.
