Don't use function calls when you can use direct matching. It's more
efficient and much easier to read:
(defquery search-result
(declare (variables ?X))
(Result (ClassRecognized ?X)))
)

You're thinking too procedurally! Don't use a query and then iterate
over the results; just write a rule that matches the facts of
interest and modify them on the RHS:
(defrule modify-facts
(modify-facts ?X)
?R <- (Result (ClassRecognized ?X))
=>
(modify ?R (whatever whatever)))
Then instead of using your "query-facts" function, just assert
"(modify-facts "Artificial")" and run the engine.
