getInferenceType

public String getInferenceType(String supportId)

parseSupports

public ArrayList<Integer> parseSupports(String supportId)

Parse support / proof statements in E's response

parseProofStep

public ProofStep parseProofStep(String line)

Parse a step like the following into its constituents fof(c_0_5, axiom, (s__subclass(s__Artifact,s__Object)), c_0_3). fof(c_0_2, negated_conjecture, (~(?[X1]:(s__subclass(X1,s__Object)&~$answer(esk1_1(X1))))), inference(assume_negation,[status(cth)],[inference(add_answer_literal,[status(thm)],[c_0_0, theory(answers)])])).

processAnswers

public void processAnswers(String line)

Return bindings from E's answer tuples

findTypesForSkolemTerms

public static void findTypesForSkolemTerms(TPTP3ProofProcessor tpp,
                                           KB kb)

Return the most specific type for skolem variable.

Parameters:

tpp - The structure learned from E's response

kb - The knowledge base used to find skolem term's types For example, original binding = esk3_0 set binding = "An instance of Human" (Human is the most specific type for esk3_0 in the given proof) original binding = esk3_1 set binding = "An instance of Human, Agent" (If multiple types are found for esk3_1)

printAnswers

public void printAnswers()

Print out E's bindings

parseProofOutput

public static TPTP3ProofProcessor parseProofOutput(LineNumberReader lnr,
                                                   KB kb)

Compute bindings and proof from E's response

parseProofOutput

public static TPTP3ProofProcessor parseProofOutput(ArrayList<String> lines,
                                                   KB kb)

Compute binding and proof from E's response

parseAnswerTuples

public static ArrayList<String> parseAnswerTuples(String st,
                                                  KB kb,
                                                  FormulaPreprocessor fp)

Return a list of answers if E finds bindings for wh- queries. Return "Proof Found" if E finds contradiction for boolean queries. For example, tuple_list = [[esk3_1(s__Org1_1)]|_] Output = [Org1_1] tuple_list = [[esk3_0]|_] Output = [An instance of Human] (Human is the most specific type for esk3_0 in the given proof)
