Question

我正在做一个Clips项目。我试图首先存储事实（很好）。然后，我试图要求用户提供有关作为事实存储的宝石的详细信息，并根据其答案为宝石提供正确的宝石名称。

(deftemplate gem
(slot name)
(slot hardness)
(slot density)
(multislot colors))

(deffacts gems
(gem (name diamond) (hardness 10) (density 3.52) (colors yellow, brown, green, blue, white, colorless))
(gem (name corundum) (hardness 9) (density 4) (colors red, pink, yellow, brown, green, blue, violet, black, white, colorless))
(gem (name chrysoberyl) (hardness 8.5) (density 3.72) (colors yellow,brown,green))
(gem (name spinel) (hardness 8) (density 3.6) (colors red, pink, yellow, brown, green, blue, violet, white, colorless)))

(defrule reading-input
  =>
(printout t "Enter the hardness of the gem: " )
(assert (var(read)))
(printout t "Enter the density of the gem: " )
(assert (var(read)))
(printout t "Enter the color of the gem: " )
(assert (var(read))))

(defrule checking-input
(var ?hardness)
(var ?density)
(var ?colors)
(gem (name ?name1) (hardness ?hardness1) (density ?density1) (colors $?colors1))
(test (= ?hardness ?hardness1))
(test (= ?hardness ?hardness1))
(test (member$ ?hardness ?hardness1))
 =>
(printout t "Gem is " ?name1 crlf))

我是CLIPS的初学者，尽管花了数小时，却无法弄清楚如何使上述代码正常工作。任何帮助将不胜感激。谢谢。
