文章摘要
针对当前教育资源库存在的通用性差和缺乏语义查询等缺陷,将语义Web的重要基础本体及其推理和查询技术应用到教育资源领域,实现一个基于本体的教育资源推理查询原型系统。利用本体构建方法及建模工具protégé,以数据结构课程为例,构建一个基于元数据标准的教育资源领域本体;制定教育资源领域本体知识点推理规则,提出改进的语义相似度算法;设计并实现基于本体的教育资源推理查询原型系统。通过实验验证,该系统的查全率与查准率均高于基于关键字的查询。
Abstract
In view of the defects such as poor universality and lack of semantic query in current education resource, we applied the important basic ontology and its reasoning and query technologies of semantic Web to education resources, and implemented an ontology-based prototype system of education resources reasoning and query. We made use of ontology construction method and modelling tools protégé, and took the course of data structure as an example to construct a metadata standard-based education resource domain ontology; We formulated the inference rules of knowledge points for education resources domain ontology, and put forward the modified semantic similarity algorithm; finally we designed and implemented an ontology-based prototype system of education resources reasoning and query. It is verified through experiment that the recall and precision of the system are both higher than the keyword-based query.
