while modeling fuzzy sets in N3, this was kind of straightforward
to have fuzzy sets :Child and :Adult as
@prefix math: <http://www.w3.org/2000/10/swap/math#>.
@prefix fa: <fa-rules#>.
@prefix : <case001#>.
:Ann a :Person; :age 18.1666.
{?P a :Person; :age ?A.
?A math:lessThan 17}
=> {?P fa:mu (:Child 1.0)}.
{?P a :Person; :age ?A.
?A math:notLessThan 17; math:lessThan 19.
(1.0 ((?A 17)!math:difference 2)!math:quotient) math:difference ?M}
=> {?P fa:mu (:Child ?M)}.
{?P a :Person; :age ?A.
?A math:notLessThan 19}
=> {?P fa:mu (:Child 0.0)}.
{?P a :Person; :age ?A.
?A math:lessThan 17}
=> {?P fa:mu (:Adult 0.0)}.
{?P a :Person; :age ?A.
?A math:notLessThan 17; math:lessThan 19.
((?A 17)!math:difference 2) math:quotient ?M}
=> {?P fa:mu (:Adult ?M)}.
{?P a :Person; :age ?A.
?A math:notLessThan 19}
=> {?P fa:mu (:Adult 1.0)}.
so that query
@prefix q: <http://www.w3.org/2004/ql#>.
@prefix fa: <fa-rules#>.
@prefix : <case001#>.
[]
q:select {?P fa:mu ?V};
q:where {?P fa:mu ?V}.
gives answer
:Ann fa:mu (
:Adult
0.5833 ),
(
:Child
0.4167 ) .
but I'm wondering wether this is enough context insensitive..
