基于哈希学习算法的专业课程资源库安全检索方法

Secure retrieval method for professional course resource library based on hash learning algorithm

建筑管理专业具有课程资源多样、专业性强以及不断更新变化的特性,导致在资源库进行检索时的mAP值较低。为此,提出了一种基于哈希学习算法的专业课程资源库安全检索方法。该方法系统地整理、分类并描述课程资源,形成建筑管理专业课程资源本体,建立检索索引,并编码存储资源信息、属性及关联。通过哈希学习算法提取特征,生成哈希函数,将高维数据映射为低维哈希码,从而建立检索模型。当用户查询时,系统能够快速定位相关资源,并高效、安全地返回结果,实现了专业课程库的安全检索。实验结果表明,该方法能够适应课程资源的特性,使在检索时的mAP值较高,提升了用户体验,同时确保了课程资源库的安全性和稳定性。

Due to the diversity,strong professionalism,and constantly changing nature of course resources in the field of construction management,the mAP value is relatively low when searching in the resource library.Therefore,a secure retrieval method for professional course resource libraries based on hash learning algorithm is proposed.This method systematically organizes,classifies,and describes course resources to form the ontology of building management professional course resources,establishes retrieval indexes,and encodes and stores resource information,attributes,and associations.Extracting features through hash learning algorithms,generating hash functions,mapping high-dimensional data to low dimensional hash codes,and establishing retrieval models.When users query,the system can quickly locate relevant resources and efficiently and securely return results,achieving secure retrieval of professional course libraries.The experimental results show that this method can adapt to the characteristics of course resources,with high mAP values during retrieval,improving user experience while ensuring the security and stability of the course resource library.
