SPARQL：排除从查询结果数据类型URI

Question

我努力学习SPARQL查询的门生，我增加了一些人对电影本体查询时发现： Movie Ontology

我有以下简单的SPARQL查询：

Query 1: Get all movies and actors having rating more than 7.0 

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> 
PREFIX owl: <http://www.w3.org/2002/07/owl#> 
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> 
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> 

PREFIX dbo: <http://dbpedia.org/ontology/> 
PREFIX mov: <http://www.movieontology.org/2009/10/01/movieontology.owl#> 

SELECT ?subject ?actors ?rating 
    WHERE { 
     ?subject a mov:Movie; 
      mov:hasActor ?actors; 
      mov:imdbrating ?rating. 
     Filter(?rating > "7.0"^^xsd:double) 
    } 

而且我得到预期的结果：

问题是我不需要额定值栏中的^^ xsd：double uri！ 如何摆脱uri“^^ http://www.w3.org/2001/XMLSchema#double”。 在此先感谢！

Answer 1

使用str得到词汇部分

SELECT ?subject ?actors (str(?rating) AS ?r)
