摘要
开放教育资源(OER)是一种教育材料,可以在Merlot、SkillsCommons、MIT Open encourseware等不同的存储库中获得。元数据的质量促进了教育资源的搜索和发现任务。这项工作评估了SkillsCommons中4142 OER的元数据质量。我们应用监督机器学习算法(支持向量机和随机森林分类器)对描述和材料类型两个元数据进行自动分类。基于我们的数据和模型,报告了第一次分类工作的性能,准确率为70%。
Automatic classification of OER for metadata quality assessment
Open Educational Resources (OER) are educational materials that are available in different repositories such as Merlot, SkillsCommons, MIT OpenCourseWare, etc. The quality of metadata facilitates the search and discovery tasks of educational resources. This work evaluates the metadata quality of 4142 OER from SkillsCommons. We applied supervised machine learning algorithms (Support Vector Machine and Random Forest Classifier) for automatic classification of two metadata: description and material type. Based on our data and model, performances of a first classification effort is reported with the accuracy of 70%.
