Abstract
The current personalized recommendation methods for teaching resources of university courses suffer from poor recommendation effectiveness due to the absence of user tags. To address this issue, a new personalized recommendation method based on cluster analysis is proposed. The proposed method leverages web crawler technology to obtain user tags, followed by processing the tags to remove meaningless terms, normalize word forms, and perform data processing. The processed tags are used to calculate user interest preferences for each tag cluster generated by clustering. Based on this, a user interest model is built, and user similarity is calculated to determine the recommendation score of each resource. The recommended resources are then ranked according to their recommendation score and presented to the target user. Experimental results demonstrate that the proposed method achieves high accuracy, recall rate, and F1 value for personalized recommendation of teaching resources in colleges and universities. In comparison, the method proposed in this paper has a significantly shorter recommendation time of 10.65 s. Further, the proposed model not only takes less time but also has higher recommendation efficiency when compared with existing personalized recommendation methods.
由于缺乏用户标签,目前针对大学课程教学资源的个性化推荐方法存在推荐效果不佳的问题。针对这一问题,本文提出了一种基于聚类分析的新型个性化推荐方法。该方法利用网络爬虫技术获取用户标签,然后对标签进行处理,去除无意义的术语,规范词形,并进行数据处理。处理后的标签用于计算聚类产生的每个标签群的用户兴趣偏好。在此基础上,建立用户兴趣模型,计算用户相似度,从而确定每个资源的推荐得分。然后,根据推荐得分对推荐资源进行排序,并呈现给目标用户。实验结果表明,本文提出的方法在高校教学资源个性化推荐方面取得了较高的准确率、召回率和 F1 值。相比之下,本文提出的方法大大缩短了推荐时间,仅需 10.65 秒。此外,与现有的个性化推荐方法相比,本文提出的模型不仅耗时更短,而且具有更高的推荐效率。
