Question

我正在尝试从几个人那里获取DBpedia类型。我试过rdflib。这是我的代码：

from rdflib import Graph, URIRef, RDFS
from rdflib.namespace import RDF
import urllib
import re

name = u'François Hollande'

g = Graph()
uriref = URIRef("http://dbpedia.org/resource/%s" % urllib.quote(re.sub(re.compile('\s', re.U), '_', name).encode('utf-8')))
g.parse(uriref)
for s,p,o in g:
    if (p in [
         URIRef("http://www.w3.org/2002/07/owl#sameAs"),
         RDFS.seeAlso
     ]) and (uriref != o):
        g.parse(location=o)
for s,p,o in g.triples((None, RDFuriref2.type, None)):
    print o

如您所见，我试着看看数据库中是否有一些“同义词”。我这样做是因为“FrançoisHollande”上的图表将返回此状态（状态为303）：

<rdf:RDF
   xmlns:owl="http://www.w3.org/2002/07/owl#"
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
>
  <rdf:Description rdf:about="http://dbpedia.org/resource/Fran%C3%A7ois_Hollande">
    <owl:sameAs rdf:resource="http://dbpedia.org/resource/Fran%C3%A7ois_Hollande"/>
    <owl:sameAs rdf:resource="http://dbpedia.org/resource/François_Hollande"/>
  </rdf:Description>
</rdf:RDF>

但是，我的代码发送了一个UnicodeEncodeError。我不知道如何调用第二个资源而不提高它。如果我在python shell上手动调用它，我会得到这个：

>> g.parse('http://dbpedia.org/resource/François_Hollande')

    return getattr(self._sock,name)(*args)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe7' in position 18: ordinal not in range(128)

感谢您的任何建议！

使用rdflib.Graph获取有关具有特殊字符的名称的类别，例如“FrançoisHollande”
