摘要
语义链接构建原则包括链接来源确定、链接对象评价与链接属性选择,而链接类型则分为概念间的词汇型链接与实体间的关系型链接。基于此,图书馆可利用SPARQL查询从目标数据集中选择满足链接要求的术语变量,或通过基于本体映射的相似度计算在概念间构建词汇型链接。另一方面,关系型链接构建可利用SPARQL查询寻找与馆藏存在语义相似性的实体并判断其语义关系,或利用字符串相似度匹配对资源文本特征属性进行精确匹配,从而实现图书馆与外部关联数据集的链接构建与资源共享。
The principles of semantic link construction include link source confirmation,link target evaluation and link attribute selection, while the types of semantic link can be divided into vocabulary link and relational link. Based on this, library is able to use SPARQL requirement to select term variables which meet the requirement of link construction from target datasets,or construct vocabulary links between heterogeneous concepts by means of similarity calculation based on the term mapping. On the other hand,relational link construction can also use SPARQL requirement to search the entity objects which are similar to collection and judge their semantic relation,or use the string similarity matching to match the text characteristic attributes of linked data resources,thus realize the link construction and resource sharing between library and external linked datasets.
