摘　　要：当前远程多媒体教育资源的检索方法主要利用关键字匹配,在多节点资源检索情况下,检索路径较长,难以实现准确快速检索的需求,因此设计一种基于知识图谱的远程多媒体教育网络资源检索方法。分析教育网络资源库中各资源的组织框架,通过爬虫建立网点,判断网页库抓取的网页是否为检索领域,在领域内进行内容提取,获取内容标签,对资源数据库进行去重与筛选,进行机器与人工的双重语义标注,获取远程多媒体教育网络资源的知识图谱,获取检索推荐结果。为分析检索方法的有效性进行性能测试实验,结果表明,设计的基于知识图谱的远程多媒体教育网络资源检索方法检索路径平均为22.85,说明该方法具有一定的可靠性和实用性。The current retrieval methods of remote multimedia education resources mainly use keyword matching.In the case of multi-node resource retrieval,the retrieval path is long,and it is difficult to achieve the requirements of accurate and fast retrieval.A retrieval method of remote multimedia education network resources based on knowledge atlas is designed.Then the paper analyzes the organizational framework of each resource in the education network resource database,establishes a website through the crawler,judges whether the pages captured by the website database are retrieval fields.It extracts the content in the field,obtains the content tags,deduplicates and filters the resource database,carries out the dual semantic annotation of machine and human,obtain the knowledge map of remote multimedia education network resources,and obtains the retrieval recommendation results.In order to analyze the effectiveness of the retrieval method,the performance test experiment is carried out.The results show that the average retrieval path of the distance multimedia education network resource retrieval method designed based on the knowledge map is 22.85,indicating that the method has certain reliability and practicality.
