SPARQLWrapper :查询本地文件中的本体时出现问题

Question

我正在使用SPARQLWrapper，并且我正在遵循文档。下面是我的代码：

queryString = "SELECT * WHERE { ?s ?p ?o. }"

sparql = SPARQLWrapper("http://example.org/sparql")# I replaced this line with 
sparql = SPARQLWrapper("file:///thelocation of my file in my computer")

sparql.setQuery(queryString)

try :
   ret = sparql.query()
   # ret is a stream with the results in XML, see <http://www.w3.org/TR/rdf-sparql-XMLres/>
except :
   deal_with_the_exception()  

我收到以下两个错误: 1-系统找不到指定的路径2- NameError:未定义名称'deal_with_the_exception‘

Answer 1

您需要一个SPARQL端点才能使其工作。考虑在本地计算机上设置Apache Fuseki。请参阅https://jena.apache.org/documentation/fuseki2/jena
