SUO: Starter Ontology Version 2




To one and all,
I include my current draft of this work-in-progress, to let
the group see where it has gone, and determine if the direction
I am going is the way the group wishes to progress.

Starter Structural Ontology Version 2.

vocabulary of KIF in the ontology
for which no rules have been stated

 =      equality between two terms
 \=     inequality between terms 
 not    negation
 and    conjunction of two conjucts
 or      disjunction of two disjuncts 
 =>     implication of antecedents and consequent
 <=     reverse implication of consequent and antecedants
 <=>    equivalence between two sentences 
 forall universal quantifier> exists existential quantifier
 bottom the value of a partial when that function is applied
        to arguments for which the function make no sense
 true   truth value of assertions that hold
 false  truth value of assertions that do not hold

Possibly needed Set Relations (but undefined)
intersection, union, partition, complement

Relations in Starter KB:

(INSTANCE-OF ?INS ?TYPE)
    - ?INS is an individual which is 
      a member of class ?TYPE

(SUBCLASS-OF ?SUBTYPE ?TYPE)
    - ?SUBTYPE is a class which is a 
      subclass of class ?TYPE

(NTH-DOMAIN ?REL ?POS ?TYPE)
    - the argument in position ?POS
      of relation ?REL is a member of class ?TYPE.
      ?POS=0 is used for the return type
      of functional relations.

(NTH-SUBCLASS ?REL ?POS ?TYPE)
    - the argument in position ?POS
      of relation ?REL is a subclass of class ?TYPE.
      ?POS=0 is used for the return type
      of functional relations

(VALENCE ?REL ?COUNT)
    - the COUNT of arguments that the
      relation ?REL can take is the number ?COUNT
      Note: an assertion is not stated when a
      relation can take an arbitrary NUMBER of arguments

(LENGTH ?ASRT ?COUNT)
    - the count of arguments that are present
      in the assertion ?ASRT is the number ?COUNT.
      ?COUNT=0 is used for an assertion with
      only the relation present.

(NTH-ARGUMENT ?A ?P ?I)
    - the argument in position ?P in the
      assertion ?A is the individual ?I.
      ?P=0 is used for the individual 
      representing the relation of the assertion.

(NTH-ARGUMENT-NAME ?R ?P ?S)
    - the documented preferred name of the variable
      in position ?P used in expressing assertions 
      with relation ?R expressed as a string ?S.


(NAME-OF ?INS ?NAME)
    - A name of the individual ?INS as a string ?NAME
      ?NAME cannot be the empty string.
      two assertions in the same context cannot
      have the same string as a name.

(AUTHOR ?INS ?WHO)
    - the name of the person as a string ?WHO who added
      the individual ?INS to the Standard Upper Ontology

(REVISION ?INS ?ID)
    - the revision identified by the string ?ID is the
      initial one in which the individual ?INS was part
      of the Standard Upper Ontology

(TRANSITIVE-THROUGH ?REL-BASE ?REL-PIPE)
    - the relation ?REL-BASE is transitive through
      the relation ?REL-PIPE.

(NUM-SUCC ?NUM-PREV ?NUM-NEXT)
    - the number ?NUM-PREV
      is immediately followed by
      ?NUM-NEXT in numerical order

(NUM-< ?NUM-PREV ?NUM-NEXT)
    - the number ?NUM-PREV
      is eventually followed by
      ?NUM-NEXT in numerical order

Constants in Starter KB:
TOP
    - the uppermost element in the ontology
RELATION
    - class of RELATIONs used in an assertion
      intuitively, all 'slots' or 'properties' or 
      'relationships' or 'predicates'
POSITION
    - class of positions in an assertion
INDIVIDUAL
    - class of individuals in the KB which
      are the possible values of variables.
      coextensional with TOP
CLASS
    - class of individuals which identify
      subsets of TOP.
NUMBER 
    - class of individuals which are 
      expressed in numeric format
COUNT
    - class of numeric individuals 
      expressing a quantity.
ASSERTION
    - class of all assertions
      expressing a sentence
