As a consequence of this plan representation, subplans have conditional effects, and hence there are conditional goal conflicts. When block promotion (= subplan concatenation) cannot remove an interaction, I resort not to individual promotion (= subplan interleaving) but to confinement (falsifying preconditions of the interaction). With individual promotion out of the way, planning is a fundamentally different problem: plan structure directly reflects goal structure, plans can be conveniently composed from subplans, and each goal conflict needs to be resolved only once during the lifetime of the problem domain. Conflict analysis is computationally expensive, however, and interactions may be more easily observed at execution time than predicted at planning time. All conflict elimination decisions can be cached as annotated operators. Hence it is possible to throw away a universal plan, later reconstructing it from its component operators without doing any planning. Indeed, an algorithm resembling backchaining mindlessly reassembles just enough of a universal plan to select an action that is helpful in the current world state. Since the selected action is both a situated response and part of a plan, recent rhetoric about situated action as *opposed* to planning is defeated.

To generate natural sounding texts from these models, one needs to compensate for these semantic deficits but without compromising the principled grammatical treatments in the generator. I will talk about how the interface to our generator, Mumble-86, handles these problems, using examples from several different knowledge-based programs. Sponsor: B.

Nobody could doubt that people often make and follow plans. But the complexity, uncertainty, and immediacy of the real world require a central role for moment-to-moment improvisation. Before and beneath any planning ahead, one continually decides what to do *now*. Investigation of the dynamics of everyday routine activity reveals important regularities in the interaction of very simple machinery with its environment. Phil Agre and I have used these ideas to design a program, called Pengi, that engages in complex, apparently planful activity without requiring models of the world. ------------------------------ Date: Tue, 8 Dec 87 09:05 EST From: Pierre LAFORGUE <mcvax!imag!pierre@uunet.UU.NET> Subject: ACM-SIGIR88 : LAST CALL CALL FOR PAPERS SIGIR 88 in cooperation with the ACM 11th INTERNATIONAL CONFERENCE ON RESEARCH AND DEVELOPMENT IN INFORMATION RETRIEVAL ACM-SIGIR JUNE 13-15 1988 GRENOBLE (FRANCE) Conference Chairman : Yves CHIARAMELLA (USTMG - Grenoble, France) Program Comittee : M.ADIBA (F) G.KNORZ (Germany) R.BOUCHE (F) S.MIRANDA (F) A.BOOKSTEIN (USA) C.D.PAICE (UK) M.F.BRUANDET (F) F.RABITTI (I) E.CHOURAQUI (F) V.V.RAGHAVAN (USA) W.B.CROFT (USA) K.VAN RIJSBERGEN (UK) T.E.DOSZKOCS (USA) G.SALTON (USA) A.S.

Deriving structures from the particularities of these tasks and from the relationships among tasks is one representational problem which needs to be addressed in designing computer support for such tasks. Another is how to acknowledge the influence of contexts on tasks. A third problem is how to decrease the probability of miscommunication and increase that of shared interpretations in complex organizations. The perspectives of discourse analysis, semantic analysis, and figurative language analysis seem to be appropriate to this set of questions. In this talk, I will discuss how these types of observation and analysis might be employed in designing research methods appropriate to knowledge acquisition for tasks in unstructured work domains. ------------------------------ Date: Thu, 10 Dec 87 11:48 EST From: emma@russell.stanford.edu Subject: From CSLI Calendar, December 10, 3:10 [Excerpted from CSLI Calendar] Representation Strategies in LILOG Hans Uszkoreit IBM Germany and University of Stuttgart LILOG (Linguistic and Logic Methods for Knowledge-based Natural-Language Understanding) is a basic research project funded by IBM Germany. It is jointly conducted by the science and technology division of IBM Germany and partner projects at five German universities. The long-term goal of the project is to develop a knowledge-based text-understanding system for German. The methods that are used in the design of the linguistic components of LILOG share relevant features with ongoing work in the FOG project at CSLI. The talk will start with an overview of the objectives, organization, and status of the project. The underlying language for the representation of linguistic and extra- linguistic knowledge is STUF (Stuttgart Type Unification Formalism). The formalism has been implemented as a data type whose operations can be utilized by all modules of the system. In addition to standard operations such as unification, generalization, and subsumption, it provides for a generalized version of functional application. Newer developments of the STUF formalism include the integration of free- arity and fixed-arity types and the introduction of knowledge domains. Examples will be presented that demonstrate how the uniform formalism is employed to account for the interaction of syntax and semantics. -------------- CSLI SEMINAR Interpretation as Abduction Jerry R. Hobbs December 17, 1987 2:15, Redwood Hall G-19 The goal of the TACITUS project at SRI is investigate the use of commonsense knowledge in the interpretation of discourse. We have recently developed a new scheme for abductive inference that yields a dramatic simplification of our characterization of what interpretation is. I will discuss its use in solving various local pragmatics problems, such as the resolution of reference, metonymy, and syntactic ambiguity problems and the interpretation of compound nominals. The scheme also suggests an elegant way to integrate syntactic and pragmatic processing, and this will be discussed briefly. ------------------------------ Date: Thu, 10 Dec 87 14:29 EST From: rjb%research.att.com@RELAY.CS.NET Subject: Intl. Conference on Principles of KR&R CALL FOR PAPERS FIRST INTERNATIONAL CONFERENCE ON PRINCIPLES OF KNOWLEDGE REPRESENTATION AND REASONING Royal York Hotel Toronto, Ontario, CANADA May 15-18, 1989 Sponsored by the Canadian Society for Computational Studies of Intelligence, with support from AAAI, IJCAI, the Canadian Institute for Advanced Research, and the Information Technology Research Centre of Ontario, in cooperation with AISB and ACM SIGART (pending approval) The idea of explicit representations of knowledge, manipulated by general-purpose inference algorithms, underlies much of the work in artificial intelligence, from natural language to expert systems. A growing number of researchers are interested in the principles governing systems based on this idea. This conference will bring together these researchers in a more intimate setting than that of the general AI conferences. In particular, all authors will be expected to appear and give presentations of adequate length to present substantial results. Accepted papers will be collected in a conference proceedings, to be published by Morgan Kaufmann Publishers, Inc. The conference will focus on principles of commonsense reasoning and representation, as distinct from concerns of engineering and details of implementation. Thus of direct interest are logical specifications of reasoning behaviors, comparative analyses of competing algorithms and theories, and analyses of the correctness and/or the computational complexity of reasoning algorithms. Papers that attempt to move away from or refute the knowledge-based paradigm in a principled way are also welcome, so long as appropriate connections are made to the central body of work in the field. Submissions are encouraged in at least the following topic areas: Analogical Reasoning Qualitative Reasoning Commonsense Reasoning Temporal Reasoning Deductive Reasoning Planning Diagnostic and Knowledge Representation Formalisms Abductive Reasoning Theories of the Commonsense World Evidential Reasoning Theories of Knowledge and Belief Inductive Reasoning Belief Management and Revision Nonmonotonic Reasoning Formal Task and Domain Specifications REVIEW OF PAPERS The Program Committee will review extended abstracts (not complete papers). Each submission will be read by at least two members of the Committee and judged on clarity, significance, and originality. An important criterion for acceptance of a paper is that it clearly contribute to principles of representation and reasoning that are likely to influence current and future AI practice. Extended abstracts should contain enough information to enable the Program Committee to identify the principal contribution of the research and its importance. It should also be clear from the extended abstract how the work compares to related work in the field. References to relevant literature must be included. Submitted papers must never have been published. Submissions must also be substantively different from papers currently under review and must not be submitted elsewhere before the author notification date (December 15, 1988). SUBMISSION OF PAPERS Submitted abstracts must be at most eight (8) double-spaced pages. All abstracts must be submitted on 8-1/2" x 11" paper (or alternatively, a4), and typed in 12-point font (pica on standard typewriter). Dot matrix printout is not acceptable. Each submission should include the names and complete addresses of all authors. Also, authors should indicate under the title which of the topic ares listed above best describes their paper (if none is appropriate, please give a set of keywords that best describe the topic of the paper). Abstracts must be received no later than November 1, 1988, at the address listed immediately below. Authors will be notified of the Program Committee's decision by December 15, 1988. Final camera-ready copies of the full papers will be due a short time later, on February 15, 1989. Final papers will be at most twelve (12) double-column pages in the conference proceedings.

Rapaport <rapaport@cs.Buffalo.EDU> Subject: Seminar - The Psychology of Everyday Things (Suny Buffalo) STATE UNIVERSITY OF NEW YORK AT BUFFALO The Steering Committee of the GRADUATE STUDIES AND RESEARCH INITIATIVE IN COGNITIVE AND LINGUISTIC SCIENCES PRESENTS DONALD A. NORMAN Institute for Cognitive Science University of California, San Diego THE PSYCHOLOGY OF EVERYDAY THINGS How do we manage the tasks of everyday life? The traditional answer is that we engage in problem solving, planning, and thought. How do we know what to do? Again, the traditional answer is that we learn, in part through experience, in part through instruction. I suggest that this view is misleading. Less planning and problem solving is required than is commonly supposed. Many tasks need never be learned: the proper behavior is obvious from the start. The problem space for most everyday tasks is shallow or narrow, not wide and deep as the tradi- tional approach suggests. The minimization of the problem space occurs because natural and contrived properties of the environment combine to constrain the set of possible actions. The effect is as if one had put the knowledge required to do a thing on the thing itself: the knowledge is in the world. I show that seven stages are relevant to the performance of an action, including three stages for execution of an act, three for evaluation, and a goal stage. Consideration of the rule of each stage, along with the principles of natural mappings and natural constraints, leads to a set of psychological principles for design. Couple these principles with the suggestion that most real tasks are shallow or narrow, and we start to have a psychology of everyday things and everyday actions. The talk itself is meant to be light and enjoyable. However, there are profound implications for the type of theory one develops for simulating cognitive computation. There are serious implications for massively parallel structures (what we call Parallel Distributed Processing or connectionist approaches), for memory storage and retrieval via descrip- tions or coarse coding, and, in general, for a central role for pattern matching, constraint satisficing, and nonsymbolic processing mechanisms in human cognition. But the main implications of the work are for the design of understandable and usable objects. Monday, February 1, 1988 4:00 P.M.

Hegg <ROSIE at XX.LCS.MIT.EDU> Re: Jon Doyle seminar on 12/18 at 2pm DATE: December 18, 1987 TIME: Refreshments: 1.45 pm Lecture: 2:00PM PLACE: NE43-8th floor playroom ON UNIVERSAL THEORIES OF DEFAULTS JON DOYLE Department of Computer Science Carnegie Mellon University ABSTRACT Though unifications of some of the numerous theories of default reasoning have been found, we bolster doubts about the existence of universal theories by viewing default reasoning from the standpoint of decision theory as a case of rational self-government of inference. Default rules express not only methods for deriving new conclusions from old, but also preferences among sets of possible conclusions. Conflicting default rules, which form the central difficulty in the theories, represent inconsistent preferences about conclusions. These conflicting rules arise naturally in practice, especially in databases representing the knowledge of several experts. We formally compare these theories of rational inference with theories of group decision making, and develop doubts about universal theories of the former by considering well-known negative results about the latter.
