THE UNIVERSITY OF TEXAS AT AUSTIN GRADUATE SCHOOL OF LIBRARY AND INFORMATION SCIENCE ARTIFICIAL INTELLIGENCE LIS 385T.15 45075 SPRING 2002 T 6:30-9:30pm; SZB 468 Professor Glynn Harmon Office: SZB 562D OH: W 2:00-3:00pm Phone: 471-3972; Fax: 471-3971 [email protected] I. COURSE DESCRIPTION A seminar style overview of the historical development of artificial intelligence, its current state-of-art, and the potential for super-intelligence. Includes a survey of AI’s documented history, key players and developmental landmarks, present approaches, knowledge-based systems (KBS) and their developmental tools, and reference resources. Focuses on the evaluation of developed AI systems for deployment in information service and decision support settings. II. OBJECTIVES, REQUIREMENTS, AND GRADING 1. To attain a general understanding of the past development of AI, its present status, and its future potential. To achieve this objective, requirements include three brief oral reports on the history of AI, its current status, and its probable future (30% of course grade—10% per report). 2. To understand the current major classes of knowledge-based systems, their applications potential in information services, developmental tools, and the process of knowledge engineering. Requirements include coverage of the textbook, acting as a discussion leader on a major KBS approach, and demonstration of a related developmental tool (30% of grade). 3. To learn to evaluate emerging and developed AI systems for potential application in an information service or decision support settings. Requirements include brief written evaluations of three developed systems (30% of grade). 4. Active, continuous and constructive participation in class discussions (10% of grade). 5. In place one of the first three major requirements above, you may elect to take a final, open-book exam covering that objective and its requirement(s). That is, you may opt not to do the required work for any one of the first three objectives and instead take a written final exam on it (which will count for 30% of the course grade). III.

Oral reports.To attain a general understanding of AI (Objective 1.), please become familiar with the www.aaai.org portal by browsing through it; also read the “Springboard” section so that you will know its limitations. Then prepare for your three brief oral class reports (10 minutes each) by selecting a linked reading of at least 10 pages for each oral report. Each oral report counts for 10% of the course grade. Grading will be done on the basis of how well it serves to accomplish the first objective, overall clarity, brevity and coherence, and recognition of significant landmarks, trends and useful resources. Please also be prepared to react or comment on the reports of others. Your first two oral reports should cover the past and/or present of AI, as well as implications or direct commentary about future prospects. Examples of such linked sites include (from the AI Overview) “What is AI?”; “Introduction to the Science of AI”; “AI’s Greatest Controversies”; “Readings Online” (about 20 articles from which to select); a description and evaluation of a “Related Web Site”; “AI in the News” (some 50 articles); or “Careers in AI”. To prepare each of your oral reports, you should try to provide a composite view of AI’s past landmarks, present status (state-of-art), and emergent major trends, insofar as you can. Please be prepared to deliver your first oral report at the second class meeting, and the second report at the third class meeting. Although there will be some duplication in the selected materials, we should be able to capture a picture of the overall AI landscape very early. You need not prepare handouts or bibliographies for the class; you may use the computer-projector to point out features of your selection. The third oral report should focus on reference resources, which describe or provide access to bibliographies, useful web sites, journals, books, encyclopedias, demonstrations, shell or knowledge engineering software or systems, applications, etc. Third reports are scheduled for the fourth class meeting. 2. Report on selected KBS. To acquire an understanding of KBSs, we will each lead a discussion on an assigned chapter in the textbook that covers a given type of KBS (rule-based expert systems, fuzzy systems, frame-based systems, neural networks, evolutionary computation, and hybrid intelligent systems) and its applications and developmental tools. To lead a discussion, you should assume that everyone has read the chapter. Present a brief (5-10 minute) summary or tutorial about the system, demonstrate the system and/or one of its developmental tools or applications (10-15 minutes), then lead a 20 minute Page 3 INSTRUCTIONS (continued) discussion by presenting one or more challenging discussion questions (you may draw on the “Questions for Review” at the end of your chapter or derive your own questions). You need not cover the highly technical or mathematical aspects of the system or its applications or tools (since we are oriented to its professional use, rather than its development). Upon concluding your oral report, please elicit a general discussion about your system, relevant problems or issues, exciting information service applications, and future potential of the technology. Take advantage of the textbook’s Appendix or the AAAI site and other sources to find a web-based demonstration of a tool or system. You should use the computer/projector to present your online demonstration of the system and its developmental tool. You need not prepare class handouts. In addition to the above discussion leadership, please issue a 1 to 2 page evaluation or rating of the KBS, its developmental tool, and vendor support. The evaluation should be intended for use by an information service or decision support organization or function that you designate, and submitted to the instructor at the conclusion of your report. You may submit copies to class members if you wish. Grading: discussion leadership counts for 15% and the written evaluation for 15% of the course grade (total 30%). Grading criteria include the oral coverage of the chapter and discussion leadership, and the apparent suitability of your rating for the application area and context that you designate. 3. Evaluation of developed KBS applications. We will review the operation of a few developed KBSs , such as Ask Jeeves, AIQ (for stock trading), DxPlain (medical diagnosis), CYC (encyclopedic system),and the Botany Knowledge Base developed by the group at UT Austin (www.cs.utexas.edu/users/mfkb/RKF/). Please draft brief written evaluations (1-2 pages each) of the suitability of three developed systems for purchase, adoption, implementation, and use in decision-making or information services functions. Such KBS systems should ultimately be useful in conventional or digital library systems, or in supporting individual information consumers. It would be helpful to read Laura Zick’s First Monday paper (item #6 in supplementary Sources above), to look at ALA’s LITA review formats (www.ala.org), to review the instructor’s published evaluation of CYC to be handed out, etc. Your written reports will be graded according to their apparent usefulness for information professionals in a context that you designate, the adequacy of cost and performance benchmarks that you employ, rigor, and overall clarity. Each report counts for 10% of the course grade (30% total). Page 4 INSTRUCTIONS (continued) 4. Final exam elective. In lieu of completing either requirement 1, 2, or 3 above, you may elect to take an open book final exam that will cover the topical material required section that you did not complete. We will discus the nature of the exam in class. Tentatively, the exam is scheduled for Tuesday, May 14, 7-10pm (location TBA). VI.
