Hi Yang, Are you behind a proxy? I’ve come across this error when protégé can’t see beyond the proxy.
See: https://mailman.stanford.edu/pipermail/protege-discussion/2007-February/000735.html for information on how to resolve this.

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 IRI http://proton.semanticweb.org/2006/05/protons#<http://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 -- Philip Alexiev <[email protected]><mailto:[email protected]> Software Engineer Ontotext AD
