Assignment 9 - Due November 16, in class - DEADLINE EXTENDED TO NOVEMBER 18, by popular request - Put papers in Prof. Marling's Stocker mailbox or under her office door by 5:00 PM on Wednesday, November 18

Notes about your Chatbot:

• Select one conversational topic for your chatbot. Your chatbot should not be a psychoanalyst, but might talk about soccer, chocolate, music, Hawaii, etc. The possibilities are endless... use your imagination!
• Change the prompt in the Eliza code to display your chatbot's name. Then change the code so that your chatbot responds to the user in their own way.
• Unlike Norvig's Eliza, your chatbot should never respond with NIL. Come up with some reasonable defaults, like, "Oh, that's very interesting..." for uncovered situations.
• Cover as many situations as possible within the scope of the conversational topic you choose.

Notes about Norvig's Code:

• Download the two files, AUXFNS.LSP and ELIZA1.LSP. Make sure you download them as plain ASCII files (which is not necessarily your browser's default), or you could have trouble using them in gcl.
• To run ELIZA1.LSP, you need to load AUXFNS.LSP and then ELIZA1.LSP into the interpreter.
• Fully understanding the auxiliary functions in AUXFNS.LSP is beyond the scope of this class. Take advantage of modular abstraction and use the included functions without worrying about their guts. (Note that you don't actually use most of this code. This is the auxiliary file for his whole book.)
• You can and should understand the ELIZA1.LSP file. However, you should expect it to take some time for you to understand it. The only conceptually new feature is the use of association lists and dotted pairs, which is explained in the LISP PowerPoint slides. Some new functions are used, and some familiar functions are used with new names. For example, Norvig has adopted the style of calling car first and cdr rest.
• The ELIZA1.LSP code is (intentionally) not very complete. One irritating feature is that Eliza does not know how to exit when you say goodbye. Implement this small extension before implementing your chatbot, both to familiarize yourself with the code and to make the code easier to test. Your chatbot must be able to exit gracefully.

Turn in:

1. A paragraph describing your chatbot's topic and explaining why someone might want to converse with your chatbot
2. Your complete LISP program, appropriately commented
3. A printed typescript of your system holding a conversation

This assignment is to be turned in, on paper, during class. Email submissions are not acceptable for this assignment.

Assignment 8 - Due November 15, by midnight

Submit a question, or questions, for possible inclusion on the final exam. Remember that it must be possible to answer the question(s) within the two hour exam period without the use of books, notes, or calculators. Choose one (1) of the following question formats:

• True/False: If you choose this option, submit eight (8) statements that are either true or false. Tell if each statement is true or false. For each false statement, explain why the statement is not true.
• Multiple Choice: If you choose this option, submit four (4) multiple choice questions. Each question should have four (4) possible answers, only one of which is correct. Indicate which of the four answers is correct for each question.
• Fill in the Blanks: If you choose this option, submit eight (8) sentences with blanks in them for the test-taker to fill in. Vocabulary terms, numbers, and other very short answers make good fill-in-the-blank items. Provide the correct answers.
• Program It: If you choose this option, describe one LISP function or Prolog program for the test-taker to write. It must be possible to write the function/program in ten lines of code or less. Provide the correct solution.

• Submit your assignment by Email to marling@ohio.edu
• The subject line for your Email should be: CS 480/580: Assignment 8 from <your name>
• Make sure that your Email message contains only plain ASCII text.
• Remember to sign your name to your message and to send a copy of the message to yourself.
• It is pretty hard to lose points for this assignment, but you can do it if your assignment is late, incomplete, in a non-ASCII format, or if you answer your own questions wrong. It would not be too hard to complete this assignment quickly... however, time and effort spent on this will most definitely pay off on the final exam.
• I reserve the right to use zero or more of your questions on the final exam.
