Method Detail

termsWithoutRelation

public static ArrayList<String> termsWithoutRelation(KB kb,
                                                     String rel,
                                                     int argnum,
                                                     int limit,
                                                     char letter)

Return a list of terms (for a given argument position) that do not have a specified relation.

Parameters:

kb - the knowledge base

rel - the relation name

argnum - the argument position of the term

limit - the maximum number of results to return, or -1 if all

letter - the first letter of the term name

termsWithoutDoc

public static ArrayList termsWithoutDoc(KB kb)

Return a list of terms that do not have a documentation string.

termsWithMultipleDoc

public static ArrayList<String> termsWithMultipleDoc(KB kb)

Return a list of terms that have more than one documentation string.

termsNotBelowEntity

public static ArrayList<String> termsNotBelowEntity(KB kb)

Return a list of terms that do not have Entity as a parent term.

childrenOfDisjointParents

public static ArrayList<String> childrenOfDisjointParents(KB kb)

Return a list of terms that have parents which are disjoint.

membersNotInAnyPartitionClass

public static ArrayList<String> membersNotInAnyPartitionClass(KB kb)

Returns a list of terms, each of which is an instance of some exhaustively decomposed class but is not an instance of any of the subclasses that constitute the exhaustive decomposition. For example, given (instance E A) and (partition A B C D), then E is included in the list of terms to be returned if E is not a instance of B, C, or D.

termsWithoutRules

public static ArrayList<String> termsWithoutRules(KB kb)

Find all terms which do not appear in any implication (rule).

quantifierNotInBody

public static ArrayList<Formula> quantifierNotInBody(KB kb)

Find cases where a variable appears in a quantifier list, but not in the body of the quantified expression. For example (exists (?FOO) (bar ?FLOO Shmoo))

Returns:

an ArrayList of Formula(s).

addToMapList

public static void addToMapList(TreeMap m,
                                String key,
                                String value)

Add a key to a map and a value to the ArrayList corresponding to the key. Results are a side effect.

addToDoubleMapList

public static void addToDoubleMapList(TreeMap m,
                                      String key1,
                                      String key2,
                                      String value)

Add a key to a map and a key, value to the map corresponding to the key. Results are a side effect.

printTermDependency

public static String printTermDependency(KB kb,
                                         String kbHref)

Show file dependencies. If two files depend on each other, show only the smaller list of dependencies, under the assumption that that is the erroneous set.

kbConsistencyCheck

public static String kbConsistencyCheck(KB kb)

Iterating through all formulas, return a proof of an inconsistent or redundant one, if such a thing exists.

main

public static void main(String[] args)

Test method for this class.
