The discrepancy between experience and eventual capacity is bridged by genetically provided information. Hence any hypothesis about the linguistic genotype (or "Universal Grammar," UG) has consequences for what experience is needed and what form people's mature capacities (or "grammars") will take. This BBS target article discusses the "trigger experience," i.e., the experience that actually affects a child's linguistic development. It is argued that this must be a subset of a child's total linguistic experience and hence that much of what a child hears has no consequence for the form of the eventual grammar. UG filters experience and provides an upper bound on what constitutes the triggering experience. This filtering effect can often be seen in the way linguistic capacity can change between generations. Children only need access to robust structures of minimal ("degree-0") complexity. Everything can be learned from simple, unembedded "domains" (a grammatical concept involved in defining an expression's logical form). Children do not need access to more complex structures. -- Stevan Harnad ARPANET: harnad@mind.princeton.edu or harnad%princeton.mind.edu@princeton.edu UUCP: princeton!mind!harnad CSNET: harnad%mind.princeton.edu@relay.cs.net BITNET: harnad%mind.princeton.edu@pucc.bitnet ------------------------------ Date: Thu, 26 May 88 14:21 EDT From: Marc Vilain <MVILAIN@G.BBN.COM> Subject: BBN AI Seminar: Josh Tennenberg BBN Science Development Program AI Seminar Series Lecture ABSTRACTION IN SYMBOLIC PLANNING Josh Tennenberg University of Rochester (josh@cs.rochester.edu) BBN Labs 10 Moulton Street 2nd floor large conference room 10:30 am, Tuesday May 31 The use of abstraction in planning is explored in order to simplify the task of reasoning about the effects of an agent's actions within a complex world. Two representational issues emerge which form the basis of this research. First, the abstract views must sanction plan construction for frequently occurring problems, yet never sanction the deduction of contradictory assertions. Second, a correspondence between the abstract and concrete views must be maintained so that abstract solutions bear a precise relationship to the concrete level solutions derived from them. These issues are explored within two different settings. In the first, an abstraction hierarchy is induced by relaxing some of the constraints on the application of actions. In the second, a predicate mapping function is defined which extends the notion of inheritance from object types to arbitrary relations and actions. ------------------------------ Date: Fri, 27 May 88 07:38 EDT From: Robert Amsler <amsler@flash.bellcore.com> Subject: CFP - Information in Text UNIVERSITY OF WATERLOO CENTRE FOR THE NEW OXFORD ENGLISH DICTIONARY 4TH ANNUAL CONFERENCE CALL FOR PAPERS - CALL FOR PANELISTS INFORMATION IN TEXT October 27-28, 1988 Waterloo, Canada This year's conference will focus on ways that text stored as electronic data allows information to be restructured and extracted in response to individualized needs. For example, text databases can be used to: - expand the information potential of existing text - create and maintain new information resources - generate new print information Papers presenting original research on theoretical and applied aspects of this theme are being sought. Typical but not exclusive areas of interest include computational lexicology, computational linguistics, syntactic and semantic analysis, lexicography, grammar defined databases, lexical databases and machine-readable dictionaries and reference works. Submissions will be refereed by a program committee. Authors should send seven copies of a detailed abstract (5 to 10 double-spaced pages) by June 10, 1988 to the Committee Chairman, Dr. Gaston Gonnet, at: UW Centre for the New OED University of Waterloo Waterloo, Ontario Canada, N2L 3G1 Late submissions risk rejection without consideration. Authors will be notified of acceptance or rejection by July 22, 1988. A working draft of the paper, not exceeding 15 pages, will be due by September 6, 1988 for inclusion in proceedings which will be made available at the conference. One conference session will be devoted to a panel discussion entitled MEDIUM AND MESSAGE: THE FUTURE OF THE ELECTRONIC BOOK. The Centre invites individuals who are interested in participating as panel members to submit a brief statement (approximately 150 words) expressing their major position on this topic. Please submit statements not later than June 10, 1988 to the Administrative Director, Donna Lee Berg, at the above address. Selection of panel members will be made by July 22, 1988. The Centre is interested in specialists or generalists in both academic and professional fields (including editors, publishers, software designers and distributors) who have strongly held views on the information potential of the electronic book.

E. Fenstad University of Oslo, Norway Cordura Conference Room, 4:15, May 26 One basic assumption of the Montague approach is the compositionality principle, i.e., the existence of a homomorphism from the "syntactic" algebra to the "semantic" algebra. But various problematic aspects of the "pull-back" from interpretation to linguistic forms argue for an independent representational level. Another problematic aspect of the Montague model is the extreme "constructionalism" of the approach, i.e., everything is constructed by abstraction from individuals and truth-values. In the talk I will give a survey of some recent work in Oslo related to these problems. ------------------------------ Date: Wed, 1 Jun 88 20:36 EDT From: Emma Pease <emma@csli.stanford.edu> Subject: From CSLI Calendar, June 2, 3:31 ANNOUNCEMENT This Thursday is the last day for the CSLI seminar and CSLI Calendar. The next CSLI Calendar will appear in late September. -------------- THIS WEEK'S CSLI SEMINAR A Report from the Situated Inference Engine Project on Pidgin, the Language of Interaction Susan Stucky (stucky.pa@xerox.com) June 2 In this seminar, we will report the design of Pidgin--the language of interaction for the Situated Inference Engine, which is an ongoing project of the Situated Language Program at CSLI. Pidgin is unlike any other designed or "formal" language its designers are aware of, being based not only on explicit theories of syntax and semantics, but also on discourse structure (including a nesting of "levels" of conversation depth), dialogue structure (based on a simple but cross-cutting notion of turn taking), simple speech acts and mood, and a notion of subject and topic. In each case, the language is designed to wear on its sleeve distilled versions of what current natural-language research takes to be essential mechanisms underlying natural human communication. (A note to linguists: while the design of languages is familiar in both computer science and artificial intelligence, it is less so in linguistics. One way to think about this is to regard the design and (soon-to-happen-we-hope) implementation of Pidgin as an example of `experimental linguistics', in contrast to the more familiar empirical linguistics. Though it's too soon to make any great claims, language design is proving to be revealing about language, its structure and embedding in the context of use and in the agent in ways that seem different from more traditional approaches.) ------------------------------ Date: Thu, 26 May 88 19:44 EDT From: Greg Lee <lee@uhccux.UHCC.HAWAII.EDU> Subject: Re: Language Learnability: BBS Call for Commentators From article <2498@mind.UUCP>, by harnad@mind.UUCP (Stevan Harnad): " ...

Neither the author (David Lightfoot) nor the editor (Stevan Harnad) participate in this group, so I don't see the point...that was simply a copy of something that will appear in a journal. Stevan isn't going to respond to postings in sci.lang. If you want a high level of sophistication in this newsgroup, I suggest that you post things with such a high level, instead of complaining about the lack thereof. I didn't appreciate that pompous letter you sent me, nor do I appreciate the attitude in the above quote. I just posted a reference to "Cross Cultural Universals of Affective Meaning", which I would consider to be a "must read". Neither you nor anyone else commented; who's going to judge which of us are the "sophisticated linguists" and which are not? There IS a lot of junk posted here. Just ignore it! By all means feel free to make valuable contributions. Complaining about the lack of same from *other* people is akin to throwing stones in a glass house.

I'm sure it's very interesting. " ... So that this will not be entirely a "meta"-posting, let me change the subject and ask a question. What do people do when they concatenate forms? Or: What is the nature of the mental representation of a pronounced phrase, some pieces of which are, or correspond to, memorized pronunciations of morphemes or words. I ask because I'm working on phonology-syntax interaction, and have come to suspect that phonological rule application and syntactic concatenation are somehow the same. Yet in the ways we usually think about them, they seem very different. For instance, suppose memorized pronunciations are something like a linked list of sound-segments. And when several such lists are concatenated, we insert a temporary link at the end of the first pointing to the second, and at the end of the second pointing to the third, and so on. This scheme would allow a given memorized form, say a morpheme, to occur only once per phrase. Although it's easy to think of counter-examples, there are lots of one-of-a-kind constraints known ... I'd be grateful for any ideas or references. Greg, lee@uhccux.uhcc.hawaii.edu ------------------------------ End of NL-KR Digest *******************
