Assignment
We will work again with information having to do with family structure. You will get an opportunity to deal with user input, error checking, control facts and (possibly) salience. [I had originally intended to have this assignment deal with finding childre n, sons, daughters, grandparents, grandmothers, grandfathers, grandchildren, grandsons, granddaughters, ancestors and descendents as well. It seemed a bit much once I got into it!] This time we will use the following deftemplate and deffacts:
(deftemplate family
(slot mother)
(slot father)
(multislot daughters)
(multislot sons))
(deffacts family-tree
(family (mother Viola) (father Holt)
(daughters Frances Mildred))
(family (mother Cora) (father Walter)
(daughters Jaunita Dorothy Peggy) (sons Norm Carson)) (family (mother Frances) (father Norm)
(daughters Susan) (sons Norman Steve)) (family (mother Susan) (father Charlie)
(daughters Melissa) (sons Chris)) (family (mother Linda) (father Steve)
(daughters Kristin) (sons Stephen Jonathan)) (family (mother Kristin) (father Ryan)
(sons RJ))
(family (mother Sandy) (father Stephen) (sons Austin Parker))
(family (mother Amy) (father Jonathan) (sons Grayson)))
For your convenience I have placed these two constructs in the file BetterFamily. CLP under the Course Materials on the course website.
Starting with the file BetterFamily.clp that I have given you, you should add the required rules so that your expert system will perform as demonstrated below. DO NOT change the 2 constructs in the original file. Here is a sample execution (Notice that it should be possible to ask for the same information more than once):
