Class Reasoner

java.lang.Object

org.semanticweb.HermiT.Reasoner

All Implemented Interfaces:

org.semanticweb.owlapi.reasoner.OWLReasoner

public class Reasoner
extends Object
implements org.semanticweb.owlapi.reasoner.OWLReasoner

Answers queries about the logical implications of a particular knowledge base. A Reasoner is associated with a single knowledge base, which is "loaded" when the reasoner is constructed. By default a full classification of all atomic terms in the knowledge base is also performed at this time (which can take quite a while for large or complex ontologies), but this behavior can be disabled as a part of the Reasoner configuration. Internal details of the loading and reasoning algorithms can be configured in the Reasoner constructor and do not change over the lifetime of the Reasoner object---internal data structures and caches are optimized for a particular configuration. By default, HermiT will use the set of options which provide optimal performance.

Returns:

getTableau

public Tableau getTableau(org.semanticweb.owlapi.model.OWLAxiom... additionalAxioms)
                   throws IllegalArgumentException

A mostly internal method. Can be used to retrieve a tableau for axioms in the given ontology manager plus an additional set of axioms.

Parameters:

additionalAxioms - - a list of additional axioms that should be included in the tableau

Returns:

a tableau containing rules for the normalised axioms, this tableau is not permanent in the reasoner, i.e., it does not overwrite the originally created tableau

Throws:

IllegalArgumentException - - if the axioms lead to non-admissible clauses, some configuration parameters are incompatible or other such errors

dumpHierarchies

                            boolean dataProperties)

Writes out the hierarchies quickly

Parameters:

out - - the printwriter that is used to output the hierarchies

classes - - if true, the class hierarchy is printed

objectProperties - - if true, the object property hierarchy is printed

dataProperties - - if true, the data property hierarchy is printed

printHierarchies

public void printHierarchies(PrintWriter out,
                             boolean classes,

                             boolean dataProperties)

Prints the hierarchies into a functional style syntax ontology all nicely sorted alphabetically.

Parameters:

out - - the printwriter that is used to output the hierarchies

classes - - if true, the class hierarchy is printed

objectProperties - - if true, the object property hierarchy is printed

dataProperties - - if true, the data property hierarchy is printed
