Q2: Consider the following pattern recognition system:

 (7 marks)

User Machine

... friend ... what about your friends?

... lie or cry ... please do not use words like that.

... I am happy ... what things make you happy?

Write makeans and recognize predicates that correspond to the above system. Make sure to return to the third question or write "Tell me more" when no matching is found.

Sol//

# Define patterns and corresponding responses
patterns = [
    ("friend", "what about your friends?"),
    ("lie", "please do not use words like that."),
    ("cry", "please do not use words like that."),
    ("happy", "what things make you happy?")
]

# Define function to recognize patterns
def recognize(input_text):
    for pattern, response in patterns:
        if pattern in input_text:
            return response
    return "Tell me more"

# Test the function
print(recognize("I have a friend"))  # Output: "what about your friends?"
print(recognize("Please don't lie"))  # Output: "please do not use words like that."
print(recognize("I am happy today"))  # Output: "what things make you happy?"
print(recognize("I am feeling sad"))  # Output: "Tell me more"


Q3: Design a minimized CFG grammar then write a Visual Prolog program that describes commands related to moving a car. The grammar should accept queries of these forms:
(7 marks)

1- "move", followed by a direction (up, down, right, or left), optionally followed by an adverb

describing speed (quickly, rapidly, or slowly).

2- "enter", followed by the, followed by a noun (park or garage).

    command(string).
    move(string, direction).
    enter(string, noun).
    exit(string, noun).

clauses
    command(Input) :-
        tokenize(Input, Tokens),
        (parse_command(Tokens, Rest, Command) ->
            format("Command: ~s~n", [Command]),
            format("Remaining tokens: ~s~n", [Rest])
        ;
            format("Invalid command.~n")
        ).

    parse_command(["move" | Tokens], Rest, Command) :-
        parse_move(Tokens, Rest, Command).
    parse_command(["enter" | Tokens], Rest, Command) :-

    parse_move([Dir | Rest], Rest, move(Dir, none)) :-
        member(Dir, [up, down, right, left]).

    parse_adverb([Adv | Rest], Rest, Adv) :-
        member(Adv, [quickly, rapidly, slowly]).
    parse_adverb(Rest, Rest, none).

    parse_enter(["the" | Rest], Rest1, enter(Noun)) :-
        parse_noun(Rest, Rest1, Noun).
    parse_exit(["the" | Rest], Rest1, exit(Noun)) :-
        parse_noun(Rest, Rest1, Noun).

    parse_noun([N | Rest], Rest, N) :-
        member(N, [park, garage]).

goal
    command("move up quickly").
    command("enter the park").
    command("exit the garage").


Q4: (7 marks)

Consider the following knowledge base. Assume that the conflict resolution strategy is to pick the

rule with the most preconditions that matches Working Memory (WM) and has not already been

used. Break ties by choosing the lowest numbered rule.

(1) A ^ ¬B → ADD(D)

(2) C ^ A ^ ¬D → DELETE(A)^ ADD(B)

(3) D → PRINT("Brilliant!")

(4) B → PRINT("Brilliant!")

(5) C ^ B → DELETE(C)^ DELETE(B) ^ ADD(A)

(6) ¬C ^ ¬A ^ ¬D ^ ¬B → PRINT("Oops!")

Assume that the system terminates when either no unused rules match Working Memory (WM) or the system executes a PRINT action. Illustrate the operation of this production system; assume that the initial contents of WM are: C, A, ¬D, ¬B.

Note: ADD’ing X means that ¬X is removed from WM and X is inserted, while DELETE’ing X

means that X is removed from WM and ¬X is inserted.

Sol//


1. Initial Working Memory (WM): C, A, ¬D, ¬B


2. Matching Rules:

   - Rule (2) matches: C ^ A ^ ¬D, has 3 preconditions

   - Rule (5) matches: C ^ B, has 2 preconditions


3. Conflict Resolution:

   - Rule (2) has more preconditions than Rule (5), so it is chosen.


4. Action:

   - DELETE(A)^ ADD(B) is executed, modifying WM to: C, ¬A, ¬D, B


5. Matching Rules with New WM:

   - Rule (1) matches: A ^ ¬B, has 2 preconditions

   - Rule (3) matches: D, has 1 precondition

   - Rule (4) matches: B, has 1 precondition


6. Conflict Resolution:

   - Rule (1) and Rule (3) have the same number of preconditions. Rule (1) is lower numbered, so it is chosen.


7. Action:

   - ADD(D) is executed, modifying WM to: C, ¬A, ¬D


8. Matching Rules with New WM:

   - Rule (6) matches: ¬C ^ ¬A ^ ¬D ^ ¬B, has 4 preconditions


9. Action:

   - PRINT("Oops!") is executed.


10. Termination: The system executes a PRINT action, so the operation terminates.

Note: Answer ONE question (12 marks)

Q1: Consider the following sentences:

1- Ali will buy a new car tomorrow.

2- Some persons can own respecting by a nice job.

Build a context free grammar for the above sentences, and then write a complete Visual Prolog program that parses them.

Sol//

S -> NP VP | Aux NP VP NP -> Pronoun | ProperNoun | Det Noun | NP PP VP -> Verb | VP NP | VP Adverb | VP PP | VP Aux VP PP -> Preposition NP Det -> "a" | "the" | "some" Noun -> "car" | "persons" | "job" ProperNoun -> "Ali" Pronoun -> "Some" Verb -> "will" | "buy" | "own" | "respecting" Aux -> "can" Adverb -> "tomorrow" | "nicely" Preposition -> "by"

parse(Sentence) :-
    atom_chars(Sentence, Chars),
    phrase(s, Chars),
    write('Parsing successful!').

s --> np, vp.
s --> aux, np, vp.
np --> pronoun.
np --> proper_noun.
np --> det, noun.
np --> np, pp.
vp --> verb.
vp --> vp, np.
vp --> vp, adverb.
vp --> vp, pp.
vp --> vp, aux, vp.
pp --> preposition, np.
det --> "a" | "the" | "some".
noun --> "car" | "persons" | "job".
proper_noun --> "Ali".
pronoun --> "Some".
verb --> "will" | "buy" | "own" | "respecting".
aux --> "can".
adverb --> "tomorrow" | "nicely".
preposition --> "by".


Q2: Do as required

a- Write a Visual Prolog program that finds the index of an element in a list L:

L= [a,b,c,d,e,f,g] index of c=3

b- Consider the following Visual Prolog program segment:

result(_, []).

result([_, E | L], [E | M]) :- result(L, M).

After having consulted this program, what would Prolog reply when presented with the following

query?

Sol//

a) Here's a Visual Prolog program that finds the index of an element in a list:

domains element = char list = element* predicates index_of(element, list, integer) clauses index_of(Element, List, Index) :- index_of(Element, List, 1, Index). index_of(_, [], _, -1). index_of(Element, [Element|_], Index, Index). index_of(Element, [_|Tail], CurrentIndex, Index) :- NextIndex = CurrentIndex + 1, index_of(Element, Tail, NextIndex, Index).


You can use the `index_of/3` predicate to find the index of an element in a list. For example:

index_of('c', [a,b,c,d,e,f,g], Index).

This will return `Index = 3`.

b) The Prolog program segment you provided defines a predicate `result/2` which succeeds when the second argument is a sublist of the first argument, with elements interspersed with other elements. For example:

result([a,b,c,d,e,f,g], [b,c,e]).

Prolog would reply `true` for this query.
