[Hints]

How to run the TalkingBoxPrologOnly.pl program:

1. Double click on the file to open it in the Prolog command line interface.
2. As the code uses the assert() function to TELL the KBS what the user likes and dislikes in order to dynamically select subsequent questions to ask, you need to use the dynamic command to let Prolog allow such assertions to modify the KBS on the fly:
3. Then, start interacting with the KBS with the ask(0). command and follow the instructions on the screen (y yes, n no, q quit).
4. To see what new likes and dislikes the KBS has learned through the interactions, you can use the following instructions:

[Choose only ONE of the following Four questions to answer]

Question 1: Ten Questions

In the two-people game of ten questions, one person is answerer and the other person is questioner. They decide one topic to confine the scope, say Olympics games. The answerer decides an Olympic game in his/her mind and does not reveal the game to the questioner. Questioner is supposed to ask a maximum of ten questions to guess the answer.

Design a Prolog script that plays the role of an answerer. For example, queries can be related to:

• Team size (2 for badminton doubles, 1 for swimming)
• Number of teams in a game (2 for badminton doubles, many for swimming)
• Arena type (court for badminton doubles, pool for swimming)
• Play device (shuttle cock or racket for badminton doubles, water for swimming, ball or racket for tennis, javelin for javelin throw, etc.)
• Game mode (knock out, timed)
• Performance type (score, win)

There should be only one form of query, for example: has(ball), has(pool), has(team), has(teamsize,2), has (teams_per_game, 2), etc. And one form of decision: is(badminton). Prolog script should be able to play the game 5 times, choosing a different game each time.

Question 2: Kids Day at School

Assume that the Prolog script is a parent, trying to know about a kids day at school. The Prolog script should converse intelligently with the kid as follows. The Prolog script should ask a question to the kid that kid can answer yes or no. Depending on whether the answer is yes or no, Prolog script should ask a related question or another random question. For example, if the kid says yes to whether it ate or not, the query can be a food item, or whether the kid used fork or spoon, or whether the kid washed hand. Similarly, related to games.

Question 3: Subway Sandwich Interactor

The Prolog script offers different meal options, sandwich options, meat options, salad options, sauce options, top-up options, sides options etc. to create a customized list of persons choice. The options should be intelligently selected based on previous choices. For example, if the person chose a veggie meal, meat options should not be offered. If a person chose healthy meal, fatty sauces should not be offered. If a person chose vegan meal, cheese top-up should not be offered. If a person chose value meal, no top-up should be offered.

Question 4: Patient with a Sympathetic Doctor

Assume that the Prolog script is a sympathetic doctor, conversing with a patient who can answer only yes or no. The doctor should be able to diagnose the patients condition while asking question sensitively depending upon patients pain level and mood level. You can choose 5 or more different mood considerations (calm, angry, etc.) and 5 or more levels of pain. Five or more diseases should be diagnosable, each disease characterized by 5 or more symptoms.
