Non-member submission from [Ron Sun <rsun(a)cecs.missouri.edu>] Date: Thu, 28 Dec 2000 18:55:37 -0600 From: Ron Sun <rsun(a)cecs.missouri.edu> To: rsun(a)cecs.missouri.edu Subject: Papers available Papers available, in both PS and PDF formats: ----------------------------------------------------------------- TITLE Symbol Grounding: A New Look At An Old Idea by Ron Sun Appeared in: Philosophical Psychology, Vol.13, No.2, pp.149-172. 2000. http://www.cecs.missouri.edu/~rsun/sun.PP00.ps http://www.cecs.missouri.edu/~rsun/sun.PP00.pdf ABSTRACT Symbols should be grounded, as has been argued before. But we insist that they should be grounded not only in subsymbolic activities, but also in the interaction between the agent and the world. The point is that concepts are not formed in isolation (from the world), in abstraction, or ``objectively". They are formed in relation to the experience of agents, through their perceptual/motor apparatuses, in their world and linked to their goals and actions. In this paper, we will take a detailed look at this relatively old issue, using a new perspective, aided by our work of computational cognitive model development. --------------------------------------------------------------- TITLE: Cognitive Science Meets Multi-Agent Systems: A Prolegomenon by Ron Sun To appear in: Philosophical Psychology, Vol.14, No.1, pp.5-28. 2001. http://www.cecs.missouri.edu/~rsun/sun.PP01.ps http://www.cecs.missouri.edu/~rsun/sun.PP01.pdf ABSTRACT In the current research on multi-agent systems (MAS), many theoretical issues related to sociocultural processes have been touched upon. These issues are in fact intellectually profound and should prove to be significant for MAS. Moreover, these issues should have equally significant impact on cognitive science, if we ever try to understand cognition in the broad context of sociocultural environments in which cognitive agents exist. Furthermore, cognitive models as studied in cognitive science can help us in a substantial way to better probe multi-agent issues, by taking into account essential characteristics of cognitive agents and their various capacities. In this paper, we systematically examine the interplay among social sciences, MAS, and cognitive science. We try to justify an integrated approach for MAS that incorporates different perspectives. We show how a new cognitive model {Clarion} can embody such an integrated approach through a combination of autonomous learning and assimilation. --------------------------------------------------------------- TITLE Accounting for the Computational Basis of Consciousness: A Connectionist Approach by Ron Sun Appeared in: Consciousness and Cognition, Vol.8, pp.529-565. December, 1999. http://www.cecs.missouri.edu/~rsun/sun.CC99.ps http://www.cecs.missouri.edu/~rsun/sun.CC99.pdf ABSTRACT This paper argues for an explanation of the mechanistic (computational) basis of consciousness that is based on the distinction between localist (symbolic) representation and distributed representation, the ideas of which have been put forth in the connectionist literature. A model is developed to substantiate and test this approach. The paper also explores the issue of the functional roles of consciousness, in relation to the proposed mechanistic explanation of consciousness. The model, embodying the representational difference, is able to account for the functional role of consciousness, in the form of the synergy between the conscious and the unconscious. The fit between the model and various cognitive phenomena and data (documented in the psychological literatures) is discussed to accentuate the plausibility of the model and its explanation of consciousness. Comparisons with existing models of consciousness are made in the end. ------------------------------------------------------------------- here is a related paper describing the details of the model: >From Implicit Skills to Explicit Knowledge: A Bottom-Up Model of Skill Learning Ron Sun Edward Merrill Todd Peterson To appear in: Cognitive Science. http://www.cecs.missouri.edu/~rsun/sun.CS99.ps http://www.cecs.missouri.edu/~rsun/sun.CS99.pdf ABSTRACT This paper presents a skill learning model {\sc Clarion}. Different from existing models of mostly high-level skill learning that use a top-down approach (that is, turning declarative knowledge into procedural knowledge through practice), we adopt a bottom-up approach toward low-level skill learning, where procedural knowledge develops first and declarative knowledge develops later. Our model is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line reactive learning. It adopts a two-level dual-representation framework (Sun 1995), with a combination of localist and distributed representation. We compare the model with human data in a minefield navigation task, demonstrating some match between the model and human data in several respects.

Andras - Tillmann J.A. ************************************************************************ ------------------------------------------------------------------------ Máz, imázs és hagymáz Tillmann J. A. Olyan korban élünk, amelyben magasan kvalifikált individuumok ezrei elõször vesznek részt hivatásszerûen a közgondolkodás alakításában, hogy manipulálják, kizsákmányolják és ellenõrizzék azt.- írja elsõ könyvében McLuhan. A médiumelmélet klasszikusának az ötvenes évek elején megjelent elemzése mit sem vesztett idõszerûségébõl. Mi több, tájainkon a közelmúlt történései különösen aktuálissá teszik gondolatait. A korábbi évtizedek korlátolt agitpropjának múltával most értünk a közgondolkodás magasan kvalifikált szakmunkások által végzett eltérítésének korába. Ennek elsõ hullámában a külföldi fejlesztésû kereskedelmi marketing mosta alá széles körben az ítélõképességet. A máshol sem sikertelen eljárások a naív és tapasztalatlan népesség körében elképesztõ eredményekre vezettek: Például egy elnyerhetõ autó igéretét, és annak jelképes kulcsát terjesztõ folyóirat-beetetési kampány nyomán, a betûre éhes, olvasó nép körébõl százezrek fizettek elõ a digesztált színességre. A késõbbiekben már magyar szakemberek honosították és fejlesztették tovább a megtévesztés bevált módozatait. És nemcsak a versenyszférában. Így aztán az utóbbi évtizedben az egy fõre esõ, hamisítatlan hazai hagymáz termelése folyvást emelkedett. Mi több, a legdinamikusabban emelkedõ ágazattá vált. Nem pusztán a nyilvánosan elhangzó, közszemlére szánt marhaságok hallatása vált gyakorivá. A jelenség nem korlátozódik a butaság emelkedett színekkel történõ ecsetelésére, a korlátoltságot kultiváló kereskedelmi megtévesztés technikáinak terjedésére. A legerõteljesebben éppen azon a területen mutatkozik, amelyen a leghathatósabb ellenállásnak kellene érvényesülnie: a közszolgálatban. Nem egyszerûen arról van szó, hogy közszolgálati médiumokban meghatározóvá vált a fideszes fénymáz, a kisgazda kvalitás és a miépes minõség. Bár ennek hatása sem elhanyagolható, kivált, hogy mindez közszolgálatként történik. Aligha van ui. hazánkon kívül olyan (nyugati) keresztény kultúrájú ország, melynek lakóit a hét hetedik napjának reggelénVasárnapi Újság-jellegû uszító butítással indítaná útjára a közszolgálati rádió. Szintúgy elképzelhetetlen, hogy az ilyen evangélium különféle vizuális változatai - mint amilyen például A hét - tûnjenek fel egy európai köztelevízióban, miként az mostanában nálunk történik. Ám a médiumegyensúly helyreállításának elbeszélése mellett zajló, és a hírlapok lenyúlására is kiterjedõ értékteremtõ tevékenység a lebutítási láncolatnak csak egyik eleme. A magasan kvalifikált fiatalok törekvése túlmegy a közszolgálati médiumok megszállásán. Szándékuk átfogónak, mi több programszerûnek tûnik: céljuk ugyanis - amint azt saját, belsõ elemzõjük, Tölgyessy Péter megállapítja - az, hogy a legsúlyosabb társadalompolitikai kérdések lehetôleg ne váljanak a közbeszéd témájává. A kormányzati reklámüzemág szólamai és képei ennek jegyében készülnek. A közfigyelemnek a súlyos kérdésekrõl történõ eltérítése többlépcsõs, komplex tevékenység. Megkívánja a közbeszédben elhallgatott kérdések nyomán keletkezett ürességnek töltelékanyagokkal történõ kitöltését. Azaz a jelentõsnek jelentéktelenné tevését, a jelentéktelennek pedig történelmivé történõ feltupírozását, a semmiségek eseményként bemutatott sokasítását. Ezért esik minden napra - ökumenikus öntömjén és ökörsütés mellett - egy-egy történelmi tapétaragasztás. Így készülnek sorozatgyártásban a különféle lepellengetések, és más korszakos események. Ezért esik minden hétre két korszakváltás és nemzetpolitikai kinyilatkoztatás. Mûködik a mahíres iparág, alakul a imázs... Bár a hagymáz széthintésében derakasan fáradoznak a józan paraszti észtõl is többnyire független kisgazdák, ám kétségkívül fiatalabb koalíciós kollégáiké az oroszlánrész. Mert míg elõbbiek anyanyelvükként beszélik, utóbbiak céltudatosan sajátították el és felkészülten ûzik. Nemcsak tanulták terjesztésének technikáit, hanem elmélyültek hazai hagyományában: hallgatnak a harmincas évek óta hibernált agyakra, a világszövetségi vajákosokra, és a Minden Határon Túli magyarokra. A folyamat példátlan az európai palettán, de sajátos elõzményei értelmezhetõvé teszik. Fõként annak folyománya, hogy a korábbi, anarchisztikus vonásoktól sem ment, liberális politikusok, választási kudarcuk nyomán azonnali arculatváltás mellett döntöttek. Az egykori fiatal demokraták úgy vélték, hogy a hatalom megszerzése érdekében minden megtehetõ, bármi elmegy. Ám a homlok mögötti állományt átállítani korántsem olyan könnyû, mint egy homlokzatot átfesteni vagy egy pártprogramot átpingálni. Az önmegmásítás kísérleteit a pszichiáterek önhamisításként írják le, és következményeit súlyosnak ítélik, mert az önátfestés kikezdi a személyiség egységét. A mai magyar közéletben ennek a neurózisnak a hatása egyre erõteljesebben megmutatkozik. A fiatal önátfestõk pártjának vezetõi most már maguk is elhiszik, amit jobbra át!-juk nyomán a fogalmazóik a szájukba adnak -- és ezzel arányosan veszítik el józan ítélõképességüket is. Ilyen körülmények közepette nem árt arra emlékeztetni, hogy a politika, a nemzet érdekében végzett közszolgálat, nem utolsó sorban a közmegegyzés megteremtésének a mûvészete. Továbbá arra, hogy a hagymáz elhatalmasodását idõvel mindig kijózanodás követi. Amikor is kiderül, milyen árat kellett fizetni érte. --------- A szerzõ egyetemi docens, médiumelméletet tanit www.c3.hu/~tillmann Tillmann Jozsef A. Dr. / Ph.D H-1O28 Budapest, Tarkony 9O.

The editors at the international journal, Science, have compiled their list of the Top 10 scientific developments for the year 2000, placing genome sequencing first on the list. Science's Top 10 research advances, chosen for their profound implications for society and the advancement of science, appear in the journal's 22 December 2000 issue. Genome sequencing steamed full speed ahead this year, as researchers used a synthesis of biology, chemistry, physics, mathematics, computer science, and engineering to decode the script of life in a variety of organisms, from people to fruit flies. A year ago, reasearchers had completely read the genome of only one multicellular organism, the worm, Caenorhabditis elegans. Now, sequences exist for the yet-to-be-published human genome, the fruit fly, and the plant geneticists' favorite weed, Arabidopsis thaliana. The genomes of several microbes have been sequenced as well, including those that cause cholera and meningitis. Close on the heels of these successes, the genomes of the mouse, rat, zebrafish, and two species of puffer fish are also nearing completion. Researchers are already reaping new knowledge from these sequencing efforts, including insights into the diversity of cancer, the causes of aging, and the complexity of the immune system. In the 21st century, researchers will decipher whole families of genes and whole pathways of interactive proteins. These advances will bring with them a host of ethical questions that we have only begun to address. Yet, genome sequencing's potential for advancing human health and our understanding of life has made its allure irresistible. Science also salutes nine other scientific achievements of 2000. Except for the first runner up, the others are in no particular order. RNA Runs the Ribosome: Last year witnessed the unveiling of the first molecular map of the ribosome, the cell's essential protein factory. In 2000, higher-resolution maps of the ribosome revealed startling details about its structure that may boost support for an "RNA world" as the model for the origin of life on Earth. Although the large unit of the ribosome consists of both ribosomal RNA (rRNA) and proteins, researchers found that the "active site" on the ribosome--the site of the chemical reaction that changes genetic information into the beginnings of a protein--contains only rRNA. This suggests that the ribosome is actually a ribozyme, an RNA molecule that can catalyze its own chemical reactions. RNA's starring role of in the ribosome may support the idea that life on Earth began with RNA. Other research in 2000 bolstered support for the ribosome's antiquity, and uncovered mechanisms in the cell that guard against defective protein production. First Out of Africa: Fossil skulls, some 1.7 million years old and unearthed from the well-dated site of Dmanisi in the Republic of Georgia, may represent the first human ancestors to journey out of Africa. According to their discoverers, the well-dated Dmanisi fossils are the first fossils discovered outside of Africa to show clear signs of African ancestry, and may be linked to the early human species Homo ergaster, the African version of Homo erectus. Relatively unsophisticated "pebble-chopper" stone tools found with the Dmanisi fossils suggest that humans may have ventured out of the African cradle earlier than previously suspected, before the development of a more advanced tool kit that included the hand ax. Plastic Electronics: This year, electrically conducting plastics formed the basis for a bevy of technological achievements using cheap and versatile organic molecules. Their discovery also won three scientists the Nobel Prize in chemistry. Two of the year's highlights: an array of hundreds of organic computer chip components on flexible plastic (for use someday in flat panel displays, electronic tags, maybe even disposable cell phones), and an organic laser, in which organic "tetracene" molecules emit light when excited by electrical current. Old Cells, New Tricks: Scientists delivered a decisive blow this year to the once-canonical notion that adult cells are wedded to their identities. In studies with mice and human transplant recipients, adult cells from certain parts of the body re-made themselves into an impressive variety of other cell types. If this identity-switching process can be controlled, healthy adult cells might be useful for repairing tissues damaged by injury or disease. In other manipulations of cell fate during 2000, researchers managed to clone pigs, which might provide a source of transplantable organs. Cloning techniques also produced a fetal guar, an endangered animal from India and southeast Asia, raising hopes for rescuing endangered species. A Watery Solar System?: The possibility of recent water flow on Mars and further convincing evidence for an ocean on the Jupiter moon Europa made headlines in 2000. High resolution images of the martian surface, captured by the Mars Orbiter Camera (MOC), showed signs of recent groundwater seepage and runoff that may be less than a million years old, and could be flowing still. Other MOC images of possible martian sedimentary rock suggest that the planet may have been a land of lakes during its earliest history. Also this year, data collected by the Galileo spacecraft on Europa's internal magnetic field and its cracked and stretched crust strengthened the case for a salty, global ocean lurking beneath the moon's icy shell. Since many researchers believe that water is essential for the existence of life, these discoveries have piqued interest in the possibility of finding life within our immediate solar neighborhood. Cosmic BOOMERANG: In 2000, researchers completed the most detailed map to date of the early universe with the help of BOOMERANG and MAXIMA, balloons armed with microwave detectors and sent aloft to probe for fluctuations in the cosmic microwave background, the afterglow of the Big Bang. The map made from these data confirm most scientists' view that the universe is flat (with no curve to space and time), but cast doubt on the current simple models of how much ordinary and dark matter exist in the universe, and how the universe went through its early expansion. Receptor Roles: Scientists gained new insight into the various roles of nuclear hormone receptors, discovering variants of these cell structures that mediate processes such as cholesterol metabolism and fatty acid production, and implicating others in diseases such as diabetes and certain types of cancer. This year's bumper crop of nuclear hormone receptor discoveries could lead to new targets and treatments for some of these diseases. Researchers also illuminated the crucial effects of the receptor called PXR, which appears to jump-start the body's response to unfamiliar chemicals, and may be involved in drug-drug interactions. Rendez-Vous with an Asteroid: After circling the asteroid Eros for less than half a year, the NEAR Shoemaker spacecraft revealed that the space rock contains some of the most primitive matter in the solar system. This discovery suggests that Eros, and other asteroids like it, are the long-sought suppliers of the most common meteorites arriving on Earth. For decades astronomers have been unable to find the source of the so-called "ordinary chondrite" meteorites, bits of the unaltered building blocks of the solar system. But Eros's elemental composition, measured as NEAR Shoemaker came closer to the asteroid than any spacecraft has before, turns out to match that of the ordinary chondrites. Quantum Curiosities: The already-weird world of quantum mechanics got a lot weirder in 2000, as the boundary between the quantum and classical world started to break down. The perplexing idea that objects can have seemingly incompatible properties, such as being in two places at once, has generally been thought to apply only to tiny particles such as electrons. This year, researchers observed this phenomenon on a much larger scale, reporting that an electric current can flow around a superconducting loop of wire in both directions at the same time. And in January, a scientist challenged another long-standing assumption by showing that quantum computers don't need a quantum property called "entanglement" to solve complex problems at lightening speed. Best Bets for Hot News in 2001: As in previous years, the editors of Science have chosen six hot topics to watch in 2001. This year, their choices include: infectious diseases, ocean studies with satellites, quality control in RNA synthesis, science funding around the world, the post-Big Bang "quark soup," and asymmetry in cell development. The editors also check in on last year's scorecard to see how well they did with their millennial predictions. Science's Top 10 also includes some other, more dubious, honors. The Meltdown of the Year goes to the federal government's pursuit of Los Alamos physicist Wen Ho Lee. The award for Disappearing Discovery of the Year goes to Archaeoraptor, thought to be a novel combination of bird and dinosaur, but exposed as the combination of two different fossils. In a box on Biomedical Ethics, Science also reviews the fallout from gene therapy fatalities and recent efforts to update international agreements governing human subjects in medical research. As the world's leading peer-reviewed general science journal, Science is uniquely suited to compile the most authoritative list of the year's scientific accomplishments. Science's Top 10 list is described in the next issue's "Breakthrough of the Year" section, which is the twelfth since Science inaugurated the feature. Editor-In-Chief Donald Kennedy writes about the "Breakthrough of the Year" report in the 22 December issue's editorial, which is available upon request. http://www.eurekalert.org/releases/aaas-stt121400.html Human Nature After Darwin http://www.amazon.com/exec/obidos/ASIN/0415212448/darwinanddarwini/ Evolutionary psychology archive of messages: http://www.egroups.com/messages/evolutionary-psychology Join the Human Behaviour and Evolution Society http://www.des.ucdavis.edu/hbesrenew/

Third International and Interdisciplinary Conference on Context

by George Kampis

> CONTEXT'01: Third International Conference on > Modeling and Using Context > > Dundee, Scotland > July 27-30, 2001 > > http://www.context.umcs.maine.edu/CONTEXT-01 > (mirrored at http://www.cee.hw.ac.uk/context-01) > > The Third International and Interdisciplinary Conference on Modeling and > Using Context (CONTEXT'01) aims at providing a high quality forum for > discussions on context among researchers active in Artificial Intelligence, > Cognitive Science, Computer Science, Linguistics, Organizational Sciences, > Philosophy, and Psychology. > > The importance of the notion of context is widely acknowledged, as evidenced > by the numerous workshops, symposia, and seminars on context held recently > (see the Context Web Site). The CONTEXT series of conferences has a unique > place among these due to its strong emphasis on interdisciplinary research. > The first conference in this series (CONTEXT'97) was held in Rio de Janeiro > in 1997. The second conference (CONTEXT'99) was held in Trento in 1999; see > http://www.cs.unitn.it/CONTEXT-99 for details. > > TOPICS OF INTEREST > > The following topics, in which contexts can be studied and/or applied, are > indicative of the scope of the conference: > > * Case-Based Reasoning > * Cognitive Modeling > * Commonsense Reasoning > * (Active) Databases > * Decision Support Systems > * Distributed Information Systems > * Formal Theories of Context > * Heterogeneous Information Integration > * Human-Computer Interaction > * Information Management > * Intelligent Internet Systems > * Intelligent Tutoring Systems > * Knowledge Engineering > * Knowledge Management > * Knowledge Representation > * Machine Learning > * Multi-Agent Systems > * Natural Language Processing > * Natural Language Semantics > * Organizational Contexts > * Philosophical Foundations > * Pragmatics > > This is not an exhaustive list; other contributions on context are welcome. > > PUBLICATION PLANS > > As was the case with CONTEXT'99, the proceedings of CONTEXT'01 will be > published by Springer-Verlag as a volume in their series Lecture Notes in > Artificial Intelligence (LNAI), a subseries of Lecture Notes in Computer > Science (LNCS). Copies of the volume will be distributed to registered > participants at the conference. Publication of an accepted paper in the > proceedings will be conditional upon two things: presentation of the paper > during the conference and registration of at least one of its authors at the > conference. > > SUBMISSION OF PAPERS > > CONTEXT'01 is meant to provide an interdisciplinary forum. All submissions, > in addition to being evaluated for their technical and theoretical merit, > will be evaluated for their accessibility to an interdisciplinary community. > Accordingly, works that transcend their disciplinary boundaries are > especially encouraged. > > Each submission will be evaluated by three referees. > > Submissions must include in their first page: title, author's name, > affiliation, complete mailing address, phone/fax numbers, e-mail address, > and an abstract. Prospective authors are strongly advised to see the sample > paper at: > > * http://www.springer.de/comp/lncs/instruct/typeinst.pdf or > * http://www.springer.de/comp/lncs/instruct/typeinst.ps > > for the formatting requirements. It is crucial to note that papers cannot be > longer than 14 pages. Detailed information for authors is available at > http://www.springer.de/comp/lncs/authors.html. > > Only electronic submissions (PostScript or PDF file only, named with the > first author's name and last name, e.g. John-Doe.ps or John-Doe.pdf) are > acceptable. It would be wise to use a well-known compression utility (e.g. > compress or gzip) before a paper is e-mailed. If one foresees problems in > submitting his/her paper in one of the allowed electronic formats and would > like to send hardcopy instead, then he/she should send e-mail to one of the > Program Co-Chairs well in advance of the submission deadline and seek > advice. LNCS is now published both in print and in a full-text electronic > version; therefore, the electronic files are indispensable. > > Submitted papers should be received by the Conference Chair no later than > February 2, 2001: > > Paolo Bouquet > CONTEXT'01 Conference Chair > Department of Computer Science > University of Trento > Via Inama, 5 > I-38100 Trento, Italy > tel: +39 461 882135 > fax: +39 461 882124 > bouquet(a)cs.unitn.it > http://www.cs.unitn.it/~bouquet > > SPECIALIZED WORKSHOPS > > CONTEXT'01 expands the format of CONTEXT'97 and CONTEXT'99 in that > specialized workshops are planned to let participants discuss emerging, > narrow, and technical issues related to context. Proposals for specialized > workshops should be sent to the Workshops Chair by March 2, 2001: > > Massimo Benerecetti > CONTEXT'01 Workshops Chair > Department of Physical Sciences > University of Naples "Federico II" > Complesso Monte Santangelo > via Cinthia > 80126 Napoli, Italy > Massimo.Benerecetti(a)na.infn.it > > A proposal should consist of the following items: workshop title, address > and short bio of the workshop director, one-page synopsis of the workshop, > addresses of workshop speakers who have already committed to making > presentations, and tentative titles of the presentations. > > It is up to the workshop director to decide whether the workshop speakers > also prepare written versions of their presentations.
