Извлечение значений из классов OWL

0 голосов
/ 28 февраля 2012

Я использую рассуждение FaCT ++ и API OWL Манчестера, представленные здесь: http://owlapi.sourceforge.net/

У меня есть OWL, детализирующий элементы в периодической таблице, однако я изо всех сил пытаюсь извлечь буквальные значения некоторыхсвойства.В приведенных ниже примерах я хочу извлечь целые числа между тегами. 

<owl:qualifiedCardinality rdf:datatype="&xsd;nonNegativeInteger">1</owl:qualifiedCardinality>

<owl:hasValue rdf:datatype="&xsd;integer">13</owl:hasValue>

Я много разбираюсь в API, но не могу найти ничего, что позволило бы мнесделать прямое извлечение.До сих пор я был в состоянии пройти до 

<owl:onProperty rdf:resource="&atoms;contains"/>

, но не дальше.

Каждый элемент описан в сове: Class.Здесь нет заявленных лиц. 

<owl:Class rdf:about="&atoms;AluminumAtom">
    <rdfs:subClassOf>
        <owl:Restriction>
            <owl:onProperty rdf:resource="&atoms;hasValenceElectronShell"/>
