CPE 481Knowledge-Based SystemsWinter 2004 Assignment 2: Family Relationships

This assignment builds upon the knowledge base for family members from the previous assignment. The task here is to specify additional relationships between individuals that can be derived from existing relationships. For example, if the "mother" and "father" relationships are given, the "parent" relationship can be derived from those, essentially by saying that if a person is somebody's father or mother, they are a parent of that person.

Below you find a partial listing for a CLIPS knowledge base on family relationships. (Your templates for the original knowledge base may be different, which can require modifications in the rules as well.) Your task is to complete the rules so that the following relationships are covered:

• parent
• sibling
• cousin (first degree only)
• brother in law, sister in law, mother in law, father in law
• grandfather, grandmother, grandparent
• great-grandfather, great-grandmother, great-grandparent
• ancestor (recursive extension of parent -> grandparent -> great-grandparent ...)

You must submit the following items:

1. a diagram of the family tree you are using
2. a file containing the knowledge base (facts and rules) for the family tree
3. a file with therules for the family relationships
4. a file with at least one test run for each of the requested relationships
5. a README file with instructions for using your program

I will use the following grading guidelines:

2. 16 points in total for the correct formulation of the relationships
3. 6 points for the test runs
4. 3 points for the README file and documentation of the source code
