The fixed point schemes have appeared to possess an advantage in allowing implicit specification of arbitrary priorities among defaults. However, they also have disadvantages, including a lack of cumulativity, and difficulty in properly representing some situations where a mere possibility of some contingency is sufficient to overcome a default. We present a model minimization scheme that supports implicit specification of priorities among defaults. The system enjoys cumulativity (like other model preference systems), and gives more satisfactory results in situations where a possibility overcomes a default. ----------- SYMBOLIC SYSTEMS FORUM The Ecology of Computation Bernard A. Huberman Dynamics of Computation Group, Xerox PARC Friday, 10 February, 3:15 Room 60:61G A most advanced instance of concurrent computation is provided by distributed processing in open systems that have no global controls. These emerging heterogeneous networks are becoming self-regulating entities, which in their behavior are very different from their individual components. Their ability to remotely spawn processes in other computers and servers of the system offers the possibility of having a community of computational agents that, in their interactions, are reminiscent of biological and social organizations. This talk will give a perspective on computational ecologies, and describe a theory of their behavior, which explicitly takes into account incomplete knowledge and delayed information on the part of its agents. When processes can choose among many possible strategies while collaborating in the solution of computational tasks, the dynamics leads to asymptotic regimes characterized by fixed points, oscillations, and chaos. We will also describe Spawn, an ongoing project that utilizes idle computational resources in a distributed network of high-performance workstations. Finally, we will discuss the possible existence of a universal law regulating the way in which the benefit of cooperation is manifested in the system. ------------------------------ Date: Wed, 8 Feb 89 12:40:39 -0500 >From: finin@PRC.Unisys.COM To: nl-kr@turing.cs.rpi.edu Subject: The PRATTFALL Machine-Translation Module (Unisys AI Seminar) AI SEMINAR UNISYS PAOLI RESEARCH CENTER Pundit's First French Lesson: The PRATTFALL Machine-Translation Module Francois-Michel Lang Unisys Paoli Research Center (lang@prc.unisys.com) This talk describes PRATTFALL (Pundit Reads And Translates Texts into French, ALbeit Loosely), a machine-translation module built on top of the PUNDIT natural-language text-understanding system. Both PRATTFALL and PUNDIT are implemented entirely in Quintus Prolog; PRATTFALL is based on Michael McCord's LMT system. There are five principal components in PRATTFALL, each of which is described in turn: * Transfer from English to French * Restructuring to conform to French syntax * Assembling lexical items * Inflection of lexical items * Cleanup of inflected lexical items The transfer component is implemented using a definite-clause grammar modelled after one of the components of PUNDIT's SPQR module. Familiarity with LMT, PUNDIT, and machine translation in general is helpful, but not necessary. 2:00 pm, Weds., February 15, 1989 Cafeteria Conference Room Unisys Paoli Research Center Route 252 and Central Ave. Paoli PA 19311 -- non-Unisys visitors who are interested in attending should -- -- send email to finin@prc.unisys.com or call 215-648-7446 -- ------------------------------ >From: Geert Adriaens <siegeert%BLEKUL60.BITNET@CUNYVM.CUNY.EDU> Date: Tue, 31 Jan 89 14:02:59 +0100 To: nl-kr@cs.rochester.edu Subject: MAIL-ADDRESSES Can't postnews, so trying this way.
