中文简介:
本文介绍了我们的工作和经验,通过使用链接的数据原理和技术,将跨大学的教育信息链接起来。更具体地说,本文主要是对27个不同的教育机构制作的视频讲座信息进行选择、提取、结构化和互联。为此,从多个网站和YouTube频道中选择的信息已根据著名词汇表(如FOAF或W3C媒体资源本体)进行了收集和结构化。为了集成这些信息,提取的视频已经在一个公共分类空间(由开放目录项目定义的分类)下进行了分类。对这一分类过程进行了评估,获得了98%的覆盖度和89%的正确度。这一过程的结果是,一个新的链接数据集已经发布,其中包含来自27个不同机构的14000多个视频讲座,并根据一个共同的分类方案进行分类。
课程简介: This paper presents our work and experience interlinking educational information across universities through the use of Linked Data principles and technologies. More specifically this paper is focused on selecting, extracting, structuring and interlinking information of video lectures produced by 27 different educational institutions. For this purpose, selected information from several websites and YouTube channels have been scraped and structured according to well-known vocabularies, like FOAF, or the W3C Ontology for Media Resources. To integrate this information, the extracted videos have been categorized under a common classification space, the taxonomy defined by the Open Directory Project. An evaluation of this categorization process has been conducted obtaining a 98% degree of coverage and 89% degree of correctness. As a result of this process a new Linked Data dataset has been released containing more than 14,000 video lectures from 27 different institutions and categorized under a common classification scheme.
