通过 owlready 加载 ontology 产生错误

Question

我想使用 ontology“dbnary”并且我正在使用 owlready 当试图从网站加载 ontology 时，我收到此错误：

也许我使用了错误的库，有没有可以使用 turtle 格式的 ontology 的库。我想通过那个库提取单词的同义词。

from owlready2 import *
onto_path.append(r"C:\Users\Em\Docu\tal\Substitution\fr_dbnary_ontolex\fr_dbnary_ontolex.ttl")
onto = get_ontology(r"C:\Users\Em\Docu\tal\Substitution\fr_dbnary_ontolex\fr_dbnary_ontolex.ttl")
onto.load()

#error 
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
~\Anaconda3\lib\site-packages\owlready2\driver.py in parse(self, f, format, delete_existing_triples, default_base)
    153               if not line.endswith("\n"): line = "%s\n" % line
--> 154               s,p,o = splitter.split(line[:-3], 2)
    155 

ValueError: not enough values to unpack (expected 3, got 1)

The above exception was the direct cause of the following exception:

OwlReadyOntologyParsingError              Traceback (most recent call last)
