ontology

I want to programmatically generate an ontology using OWL by supplying a vector. My goal is to be able to open the produced OWL file in Protégé and make use of Jena. Input Vector The vector which i want to pass: [[layer, network layer, data link layer, physical layer], [network, computer network], [data link], [ontology, ontology extraction]]. Expected Output The output should have the following tree-like hierarchy structure: layer -network layer -data link layer -physical layer network -computer network ontology -ontology extraction data link The hierarchical structure, where network layer is

In a knowledge representation system like RDF, which is based on creating ontological hierarchies, can a class in one context be considered an instance in another? Take the example of a triplestore which contains a library catalogue. It may contain statements such as: :Book a rdfs:Class :gullivers_travels a :Book :moby_dick a :Book This makes sense, but in another context, you may want to itemize the various editions of Moby Dick , and so it may also make sense to treat it as a class, e.g.: :moby_dick a rdfs:Class :moby_dick_manuscript a :moby_dick :moby_dick_first_edition a :moby_dick :moby

I am using Princeton's WordNet for an application, but there is no support for pronouns, conjunctions, and several other types of words within the database. Does anybody know if there is a way to supplement the Wordnet database with these types of words? Thanks, Ted First, they're missing since WordNet only contains the open-class words as described in their page: Q. Why is WordNet missing: of, an, the, and, about, above, because, etc. A. WordNet only contains "open-class words": nouns, verbs, adjectives, and adverbs. Thus, excluded words include determiners, prepositions, pronouns,

What I want to do is to get the property list from the Individual1 or from a class, Get all properties from "something" The result should be something like this (for Secret_Data): | Asset_has_Confidentiality_Importance | High | | Asset_has_Availability_Importance....| Moderate | | Asset_has_Integrity_Importance.......| Moderate | | Asset_threatenedBy_ThreatEvent.......| Compromise_sensitive_information | | Asset_threatenedBy_ThreatEvent.......| Disclosure_of_sensitive_information | | Asset_threatenedBy_ThreatEvent.......| Exploit_exposed_unauthorized_information | | Asset_threatenedBy

I am stuck in the middle of ontology creation. I want to create an OWL file using Java which is my objective. I have created the hierarchical clusters but now I have to use those clusters in ontology creation. Thanks in advance. I have tried this so far. I got Dickinson's point. Now this is my code and I am getting an Exception as Exception in thread "main" com.hp.hpl.jena.shared.BadURIException: Only well-formed absolute URIrefs can be included in RDF/XML output: Code: 57/REQUIRED_COMPONENT_MISSING in SCHEME: A component that is required by the scheme is missing. JenaOwl.java public class

I'm having trouble expressing the following situation in my Ontology: Suppose I have four people voting and four votes (so there is a one-to-one mapping between vote and voter). People can either vote yes or no. If I know the outcome of three people's votes, I ought to be able to deduce the fourth person's vote. So to reiterate: John, Bob, Mary, and Carol each vote. Since there are four people there are four votes. The outcome of the vote is a tie (2 yes, and 2 no). Later on the reasoner determines that Bob and John voted no. The reasoner should then be able to deduce that Mary and Carol voted

I have created the ontology file in the Protege and save it in the RDF/XML format. It also contains the OWL tag. So, the ontology file created by Protege and saved as RDF/XML format are actually the RDF files or the RDF form of the OWL files or the OWL format containing the RDF also or something else ? <?xml version="1.0"?> <!DOCTYPE rdf:RDF [ <!ENTITY owl "http://www.w3.org/2002/07/owl#" > <!ENTITY xsd "http://www.w3.org/2001/XMLSchema#" > <!ENTITY rdfs "http://www.w3.org/2000/01/rdf-schema#" > <!ENTITY rdf "http://www.w3.org/1999/02/22-rdf-syntax-ns#" > ]> <rdf:RDF xmlns="http://www

Maybe someone could give me a hint. Is it possible to measure the distance between 2 concepts/classes that belong to the same ontology? For example, let's suppose I have an ontology with the Astronomy class and the Telescope class. There is a link between both, but it is not a direct link. Astronomy has a parent class called Science, and Telescope has a parent class called Optical Instrument which belongs to its parent called Instrumentation, that is related to a class called Empirical Science that finally belongs to a class called Science. So there is an indirect link between Telescope and
