通过 owlready 加载本体会产生错误

问题描述

我想使用本体“dbnary”，我正在使用 owlready 尝试从网站加载本体时，出现此错误：

也许我使用了错误的库，是否有一个库可以处理海龟格式的本体。 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)

    789       else:

解决方法

来自Owlready2's doc：

Owlready2 可以：

• 以 NTriples、RDF/XML 或 OWL/XML 格式导入 OWL 2.0 本体

使用 RDFLib 解析 Turtle。
