Artificial Intelligence MCQ - Knowledge Representation

11 Consider the following rules in a rule based system:

(p thread-management-rule1
(thread ^name <x>)
→
(make(process ^name <x> ^isAlive yes))
)
(p thread-management-rule2
(thread ^name <x>)
(killed ^name <x>)
→
(make(process ^name <x> ^isAlive no))
)
Now consider the following set of WMEs-
1. (thread ^name t1)
2. (thread ^name t2)
3. (killed ^name t2)
Which of the following <rue, data> pairs would be present in the conflict set after the match phase of the inference
engine?
I. <thread-management-rule1,1>
II. <thread-management-rule1,2>
III. <thread-management-rule1,3>
IV. <thread-management-rule2,1,2>
V. <thread-management-rule2,1 3>
VI. <thread-management-rule2,2,3>

12 If specificity is employed as the conflict-resolution strategy in the answer to above question, what conclusion would be made when one rule is selected and executed? Note that the WMEx are stored in the increasing order of their timestamp values in the memory as indicated

13 If recency is employed as the conflict-resolution strategy in the answer to the previous question, what conclusion would be made when one rule is selected and executed? Note the WMEs are stored in increasing order of their timestamp values in the memory as indicated

For answering Q15 – Q19, consider the following set of rules used for giving loans in a bank:

(p N
(applicant ^name <n> ^salary <35000 ^status NIL)
→
(modify 1 ^status No)
)
(p LC1
(applicant ^name <n> ^salary >100000 ^status NIL)
(stocks ^holder <n> ^worth >20000)
→
(modify 1 ^status C1)
)
(p LC2
(applicant ^name <n> ^salary >85000 ^status NIL)
(stocks ^holder <n> ^worth >50000)
(credit ^user <n> ^score >150)
→
(modify 1 ^status C2)
)
Consider the following set of working memory elements:
1. (applicant ^name a ^salary 5000 ^status NIL)
2. (applicant ^name b ^salary 1035000 ^status NIL)
3. (applicant ^name c ^salary 95000 ^status NIL)
4. (credit ^user b ^score 100)
5. (credit ^user c ^score 155)
6. (stocks ^holder a ^worth 10000)
7. (stocks ^holder c ^worth 60000)
8. (stocks ^holder b ^worth 25000)

14 If the strategy used by inference engine is Recency then enter the element from the conflict set that will be selected for the execution. The rule data must be entered as a comma separated rule-name followed by the timestamps of matching WMEs (in the increasing order of the timestamps).
For example: If <LC1,1,2> is the selected rule-data then your answer should be: LC1,1,2

15 If the strategy used by inference engine is Specificity then enter the element from the conflict set that will be selected for the execution. The rule data must be entered as a comma separated rule-name followed by the timestamps of matching WMEs (in the increasing order of the timestamps).
For example: If <LC1,1,2> is the selected rule-data then your answer should be: LC1,1,2
