我应该把我的 owl 文件放在哪里，以便通过 python owlready 加载

Question

I'm being in final project of my study. I analyze public conversation about governor election in twitter by mention and hashtag. And then I make an ontology from its result. The ontology I make manually with protege and wish to run this protege OWL file with python. According to this link , we can load local copy of the OWL file

>>> onto = onto_path.append("/path/to/owlready/onto/")

I tried similar line of above code like this

>>> onto = onto_path.append("E:/dir/dir/ontologyfile.owl")
>>> onto.load()

but the error shows up, said that 'NoneType' object has no attribute 'load' . How can i fix this?

Answer 1

From Loading an ontology from OWL files :

If an URL is given, Owlready2 first searches for a local copy of the OWL file and, if not found, tries to download it from the Internet.

This works for me on Windows:

>>> from owlready import *
>>> onto = get_ontology("file://E:/dir/dir/ontologyfile.owl")
>>> onto.load()

As well as this:

>>> from owlready import *
>>> onto_path.append("E:/dir/dir/")
>>> onto = get_ontology("http://absulutelyrandomdomain.com/ontologyfile.owl")
>>> onto.load()
