Constructor Detail

AlchemyMlnReasoner

public AlchemyMlnReasoner(net.sf.tweety.commons.BeliefBase beliefBase)

Creates a new AlchemyMlnReasoner for the given Markov logic network.

Parameters:

beliefBase - a Markov logic network.

AlchemyMlnReasoner

public AlchemyMlnReasoner(net.sf.tweety.commons.BeliefBase beliefBase,
                          net.sf.tweety.logics.fol.syntax.FolSignature signature)

Creates a new AlchemyMlnReasoner for the given Markov logic network.

Parameters:

beliefBase - a Markov logic network.

signature - another signature (if the probability distribution should be defined on that one (that one should subsume the signature of the Markov logic network)

Method Detail

setAlchemyInferenceCommand

public void setAlchemyInferenceCommand(String inferCmd)

Sets the console command for Alchemy inference (default is 'infer').

Parameters:

inferCmd - the console command for Alchemy inference.

doQuery

public double doQuery(net.sf.tweety.logics.fol.syntax.FolFormula query)

Description copied from class: AbstractMlnReasoner

Performs the actual querying.

Specified by:

doQuery in class AbstractMlnReasoner

Parameters:

query - a fol formula guaranteed to be ground.

Returns:

the answer of the query.

reset

public void reset()

Description copied from class: AbstractMlnReasoner

Resets this reasoner (removes cached files etc.)

Specified by:

reset in class AbstractMlnReasoner
