基于知识图谱的查询语句重写机制及方法

随着语义Web技术和知识图谱的出现,目前查询模式大多要求查询结果与用户查询进行语义级匹配,简单的查询处理过程已经不能满足用户的查询需求.为此,对知识图谱查询涉及的重写技术和实现方法进行了研究,在定义SPARQL(SPARQL Protocol and RDF Query Language)查询模式的重写规则集合基础上,...

Mechanism and Method of Query Rewriting for Knowledge Graph

With the emergence of semantic web technologies and knowledge maps, most of the current query models require semantic matching between query results and user queries. The simple query process can not meet the user’s query requirements. Therefore, the rewriting techniques and implementation methods involved in knowledge graph query are studied. On the basis of defining the rewrite rule set of SPARQL(SPARQL Protocol and RDF Query Language) query mode, the SPARQL is rewritten by Prolog. In the distributed data storage environment, through the test analysis of the experimental data of LUBM(Lehigh University Benchmark), it is found that the rewritten query can mine more semantic information in the knowledge map than the original query.
