摘要

建立高等职业教育英语教学资源库是信息化改革的有效措施之一。本文首先设计了基于知识图谱的英语教学资源库基本框架,在文本语义编码的基础上,以图谱的形式对现有的教学资源组织结构和存储方式进行语义描述和组织。利用实体链接技术和知识点自动关联方法,识别文本中的实体词汇并链接到知识库中的相应实体,实现教学资源与知识点的关联。然后,计算历史学习资源与教学资源在语义特征方面的余弦相似度,根据用户兴趣与资源之间的知识关联性进行资源推荐。最后对教学资源库的性能及其对学生英语学习和教师教学能力的影响进行了评价。结果表明,用户对教学资源库各项指标的评价集中在(3.9-4.4)之间,在是/否使用资源库两种情况下,学生英语知识维度的P值分别为0.010、0.047、0.038、0.035、0.018、0.026,教师教学能力在5%的水平上存在显著差异性。本研究对如何推进英语课程建设改革、优化教学资源、提升教师整体教学能力具有指导意义。

The Construction of English Teaching Resource Base in Colleges and Universities Based on Knowledge Graphs
Establishing a teaching resource base for English in higher vocational education is one of the effective informatization reform measures. In this paper, the basic framework of English teaching resource base based on a knowledge graph is firstly designed to semantically describe and organize the existing teaching resource organization structure and storage method in the form of a graph based on text semantic coding. Using entity linking technology and knowledge point automated association method, the entity vocabulary in the text is identified and linked to the corresponding entities in the knowledge base to realize the association between teaching resources and knowledge points. Then, the cosine similarity between historical learning resources and teaching resources in terms of semantic features is calculated, and resource recommendation is carried out based on the knowledge connectivity between user interests and resources. The evaluation of the teaching resource library’s performance and its effect on students’ English learning and teachers’ teaching ability is concluded. The results show that users’ evaluations of the indicators of the teaching resource library are concentrated between (3.9-4.4), the p-values of the dimensions of students’ English knowledge in the two cases of yes/no use of the resource library are 0.010, 0.047, 0.038, 0.035, 0.018, and 0.026, and there is a significant variability of the teacher’s teaching ability at the level of 5 percent. This study offers guidance on how to promote the reform of English curriculum construction, optimize teaching resources, and enhance teachers’ overall teaching ability.
