2. As mentioned here
http://ontotext.com/kim/doc/sys-doc/DesigningOntology.html, extending
KIM ontology with new ones needs to define the new ontology based on
PROTON. However, my problem now is I have a huge and complicated
domain ontology written in OWL. Does this mean I should re-analyze the
whole domain ontology and manually align each class/properties into
PROTON? Is there any easy way to do that?
I am not aware of any automated and/or easier way to do this. Follow the
instructions in documentation (
http://ontotext.com/kim/doc/sys-doc/DesigningOntology.html ) and
especially in 3. Integrating Ontology Extensions. The important points
are that if you want your objects to be recognized in the texts, you
should follow some rules:
1. All the classes, the objects belong to, should inherit directly or
indirectly http://proton.semanticweb.org/2006/05/protons#Entity.
2. Any added classes or properties (relations) must be declared visible.
Those rules are what the LKB Gazetteer resource uses to fill its lists
from the ontology. So following them will result in the gazetteer using
the objects for recognition.
3. It is also good to be more specific with the inheritance and whenever
possible inherit some of the more specific classes in PROTON Top module.
This also servers as a base for the rules in the Jape Grammars.
3. I used Protege to open protons.owl, but it returned the
following error message. I am wondering why... (maybe this is no
longer the KIM question, but I will be very thankful if you could
offer me a few hints)
org.semanticweb.owlapi.rdf.syntax.RDFParserException:
[line=92:column=48] IRI
'http://www.w3.org/2000/01/rdf-schema##Literal' cannot be resolved
against curent base IRIhttp://proton.semanticweb.org/2006/05/protons#
Never came across this error. But you may try some other ontology
editors/viewers like Swoop or TopBraid Composer .
Greetings,
Philip
