I'm trying to negate the following:
(age "under_18")
I've tried:
(not(age "under_18"))
and
(age ~"under_18")
as part of this rule:
(defrule
?u <- (user_profile (hiv_status "neg") (age "under_18"))
?e <- (enquiry (someone_has_HIV "done"))
=>
(modify ?e (transmission_entry "yes")))
How do i do it???
Thanks folks.
