Boy (NASA-Ames & ONERA, France) Topic : HORSES HORSES ( Human - [Orbital Refueling System] - Expert System ) is a malfunction procedure-oriented diagnosis aid. It takes into account two types of logic, the functioning logic of the system to be controlled and the user logic. HORSES will be used to study a theoretical framework of the situation recognition problem. As a strategy for research in the use of expert systems for fault diagnosis this example focuses attention on three interrelated issues; 1) The characterization of the fault diagnosis process with the current ORS implementation (shuttle orbital refueling system simulator); 2) Improved understanding of how humans recognize, diagnose, and respond to system failures; and, 3) A deeper analysis of the fault diagnosis process concentration a better understanding of the knowledge and inferences required. ------------------------------ Date: Fri 24 May 85 14:19:25-PDT From: Andrei Broder <Broder@SU-SCORE.ARPA> Subject: Seminar - Temporal Logic (SU) 5/30/85 - Daniel Lehmann (Hebrew U. visiting Brandeis U.) "The temporal logic of probabilistic programs" In a joint work with S. Shelah, some extensions of the propositional temporal logic of discrete time were advocated as useful for stating and proving properties of probabilistic concurrent programs. Deductive completeness theorems were proved. In a joint work with S. Kraus corresponding decision procedures were investigated. Recently a system for describing time and knowledge has been proposed. All those systems can be characterized as two-dimensional modal logics, i.e. they involve two essentially orthogonal modalities, one of them being time, that satisfy some interchange law. The techniques involved in studying such systems and some open problems will be described. ***** Time and place: May 30, 12:30 pm in MJ352 (Bldg. 460) ****** ------------------------------ Date: Wed 29 May 85 17:16:33-PDT From: Emma Pease <Emma@SU-CSLI.ARPA> Subject: Seminar - Assumption-Based Truth Maintenance (CSLI) [Excerpted from the CSLI Newsletter by Laws@SRI-AI.] THURSDAY, June 6, 1985, 4:15 p.m. CSLI Colloquium, Redwood Hall, Room G-19 ``An Assumption-Based Truth-Maintenance System'' Johan De Kleer, Xerox PARC, Intelligent Systems Lab. This paper presents a new view of problem solving motivated by a new kind of truth maintenance system. Unlike previous truth maintenance systems which were based on manipulating justifications, this truth maintenance system is, in addition, based on manipulating assumption sets. As a consequence it is possible to work effectively and efficiently with inconsistent information, context switching is free, and most backtracking (and all retraction) is avoided. These capabilities motivate a different kind of problem-solving architecture in which multiple potential solutions are explored simultaneously. This architecture is particularly well-suited for tasks where a reasonable fraction of the potential solutions must be explored. --Johan De Kleer ------------------------------ Date: Mon, 3 Jun 85 13:10:37 EDT From: jan@harvard.ARPA (Jan Komorowski) Subject: Seminar - Spreadsheets in Logic Programming (MIT) [Forwarded from the MIT bboard by SASW@MIT-MC.] Harvard University Center for Research in Computing Technology COLLOQUIUM Spreadsheets as a Subset of Logic Programming Maarten van Emden University of Waterloo Tuesday, June 4, 1985 4:00 PM Aiken Lecture Hall 101 (Tea in Pierce Hall 213 at 3:30) ABSTRACT: We believe that currently marketed programs leave unexploited much of the potential of the spreadsheet interface. The purpose of our work is to obtain suggestions for wider application of this interface by showing how to obtain its main features as a subset of logic program- ming. Our work is based on two observations. The first is that spreadsheets would already be a useful enhancement to interactive languages such as APL and BASIC. Although Prolog is also an interactive language, this interface cannot be used in the same direct way. Hence our second observation: the usual query mechanism of Prolog does not provide the kind of interaction this application requires. But it can be provided by the incremental query, a new query mechanism for Prolog. The two observations together yield the spreadsheet as a display of the state of the substitution of an incremental query in Prolog. Recal- culation of dependent cells is achieved by automatic modification of the query in response to a new increment that would make it unsolvable without the modification.

Bolt Beranek and Newman, Newman auditorium 70 Fawcett St., Cambridge The Personal Computer as a Delivery Vehicle Gerald R. Barber Gold Hill Computers Cambridge, MA The growing interest in artificial intelligence technologies is stimulating interest in how the benefits of these technologies can be delivered on a low cost and low risk basis. This talk focuses on the elements of a personal computer based delivery vehicle for artificial intelligence applications. The combination of a growing market for artificial intelligence applications and dropping development costs have created a need for an inexpensive, PC based delivery vehicle. Some desirable characteristics of a PC delivery vehicle will be discussed including characteristics of the Golden Common Lisp implementation, performance, networking, memory needs, and use of backend machines. A strategy for the implementation of artificial intelligence technology in a cost effective and incremental fashion will also be discussed. ACM GREATER BOSTON CHAPTER SICPLAN Dear Colleague, Our June speaker, Gerry Barber, is president of Gold Hill Computers and the prime mover behind their implementation of Common Lisp for the IBM/PC. Their product Golden Common Lisp originated when Gerry spent a post-doc year in France at INRIA and found himself without adequate access to Lisp processors; hence a Lisp implementation for the IBM/PC. Prior to that Gerry studied under Carl Hewitt at MIT's AI Lab, receiving a Ph.D. in 1982. The talk should give a good perspective on where AI application languages are going and how well they are penetrating into the everyday world of low cost environments. Our group customarily meets informally for dinner at Joyce Chen's restaurant, 390 Rindge Ave., Cambridge at 6:00 P.M. (just before the meeting). If you wish to come, please call Carolyn Elson at 661-1840 before the day of the talk - early please.
