| 中文简介: |  分面浏览作为探索数据存储库的用户友好界面而变得流行。在这项工作中，作者应用关联数据设计问题来探索、可视化和使用与开放教育资源语义相关的信息，这些资源通过 OpenCourseWare Consortium 和 OCW Universia.net 共享，这两个社区由全球 280 多个成员机构组成，致力于在线分享他们的课程和开放教育资源。链接数据有可能在 OCW 数据孤岛之间建立桥梁。为了评估 OpenCourseWare 中关联数据的影响，作者展示了一个名为 Serendipity 的分面工具和一个名为 Serendipity Maps 的数据可视化 Web 界面。 Serendipity 是一个基于开放教育资源数据的面向开放教育内容的分面搜索界面。此外，链接的 OER 和 OCW 数据环境使我们能够展示数据可视化。 |
| 课程简介: | Facet browsing has become popular as a user-friendly interface to explore data repositories. In this work, the authors apply the Linked Data Design Issues to explore, visualize and use information that is semantically related to open educational resources that are shared via the OpenCourseWare Consortium and OCW Universia.net, two communities of over 280 member institutions worldwide committed to sharing their courses and OER online. Linked data have the potential of create bridges between OCW data silos. To assess the impact of Linked Data in OpenCourseWare, the authors present a faceted tool called Serendipity and a Data Visualization Web interface called Serendipity Maps. Serendipity is an interface of faceted search for open educational content based on Open Educational Resources Data. Additionally, the linked OER and OCW data environment enabled us to show data visualizations. |
