midway.uchicago.edu>ChiPhon -- the Phonetics and Phonology Group at the University of Chicago -- provides a forum for discussing fundamental questions in spoken language research. Last year, over 100 people joined us for a day-long panel on whether speech is special. This year, as part of the 34th annual meeting of the Chicago Linguistic Society, we examine how language acquisition data should be incorporated into phonological and phonetic theory. ChiPhon '98 Saturday, April 18, Chicago, Illinois THE ACQUISITION OF SPOKEN LANGUAGE "the ideal relationship between central and developmental portions of a field would be one in which the investigators in each... would construct model children who were capable of developing into adults and, conversely, model adults who could have developed from children" (Menn, 1980). * Which provides a better measure of a speaker's successful acquisition of speech -- perceiving contrasts or producing them? How are PERCEPTION & PRODUCTION related to linguistic competence? * How should acquisition data be used when formulating and evaluating phononological theories of tone and stress? What are the PROSODIC PRIMITIVES, and are they innate or can they be bootstrapped from the signal? * What speech processing mechanisms are responsible for SECOND-LANGUAGE development? Are they the same as those for adults processing L1 or for infants acquiring it? What does DISORDERED PHONOLOGY tell us about these mechanisms? We invite abstracts that treat the acquisition of spoken language as integral to the development of linguistic theory. Invited Speakers: James Flege (University of Alabama at Birmingham) Peter Jusczyk (Johns Hopkins University) Robert Port (Indiana University) CONFERENCE INFO Like last year, this year's symposium will provide ample opportunities for discussion with talks throughout the day, a box lunch, and an hour-long discussion at the end. OTHER EVENTS that weekend include a panel on LANGUAGE ACQUISITION AND THE LEXICON on April 19. * Sophisticated CONNECTIONIST MODELS of language and acquisition provide an ideal framework for constructing linguistic theories that incorporate the complex interactions between sounds, symbols and meanings. * The ways in which we conceptualize the organization of MORPHOLOGY have different implications for first and for second language acquisition. * Ontogeny recapitulates phylogeny and for mature organisms we look at LEXICAL ACCESS convinced cognition then recapitulates ontogeny. Invited speakers: Joan Bybee (University of New Mexico) David Pisoni (Indiana University) Terry Regier (University of Chicago) The CLS conference will also host a panel on The Status of Constraints in Linguistic Theory on April 17, with John McCarthy and Jerrold Sadock. Papers on phonology, morphology, and syntax, among others, will be presented during the main sessions on April 17-19, with Diana Archangeli and David Dowty.

dcs.shef.ac.uk>Call for papers Distributing and Accessing Linguistic Resources Workshop immediately before the First International Conference on language Resources and Evaluation (LREC), May 27 1998 Granada, Spain http://www.icp.grenet.fr/ELRA/conflre.html Short description: This workshop will discuss ways to increase the efficacy of linguistic resource distribution and programmatic access, and work towards the definition of a new method for these tasks based on distributed processing and object-oriented modelling with deployment on the WWW. Organizers: Yorick Wilks, Hamish Cunningham, Wim Peters, Remi Zajac Workshop Scope and Aims - --------------------- In general the reuse of of NLP data resources (such as lexicons or corpora) has exceeded that of algorithmic resources (such as lemmatisers or parsers). However, there are still two barriers to data resource reuse: 1) each resource has its own representation syntax and corresponding programmatic access mode (e.g. SQL for CELEX, C or Prolog for Wordnet, SGML for the BNC); 2) resources must generally be installed locally to be usable (and of course precisely how this happens, what operating systems are supported etc. varies from case to case). The consequences of 1) are that although resources share some structure in common (lexicons are organised around words, for example) this commonality is wasted when it comes to using a new resource (the developer has to learn everything afresh each time) and that work which seeks to investigate or exploit commonalities between resources (e.g. to link several lexicons to an ontology) has to first build a layer of access routines on top of each resources. So, for example, if we wish to do task-based evaluation of lexicons by measuring the relative performance of an information extraction system with different instantiations of lexical resource, we might end up writing code to translate several different resources into SQL or SGML. The consequence of 2) is that there is no way to "try before you buy": no way to examine a data resource for its suitability for your needs before licencing it. Correspondingly there is no way for a resource provider to expose limitted access to their products for advertising purposes, or gain revenue through piecemeal supply of sections of a resource. This workshop will discuss ways to overcome these barriers. The proposers will discuss a new method for distributing and accessing language resources involving the development of a common programmatic model of the various resources types, implemented in CORBA IDL and/or Java, along with a distributed server for non-local access. This model is being designed as part of the GATE project (General Architecture for Text Engineering: http://www.dcs.shef.ac.uk/research/groups/nlp/gate/) and goes under the provisional title of an Active CREOLE Server. (CREOLE: Collection of REusable Objects for Language Engineering. Currently CREOLE supports only algortihmic objects, but will be extended to data objects.) A common model of language data resources would be a set of inheritance hierarchies making up a forest or set of graphs. At the top of the hierarchies would be very general abstractions from resources (e.g. lexicons are about words); at the leaves would be data items that were specific to individual resources. Programmatic access would be available at all levels, allowing the developer to select an appropriate level of commonality for each application. Note that although an exciting element of the work could be to provide algorithms to dynamically merge common resources (e.g. connect WordNet to Celex), what we're suggesting initially is not to develop anything substantively new, but simply to improve access to existing resources. This is NOT a new standards initiative, but a way to build on previous initiatives. Of course, the production of a common model that fully expressed all the subtleties of all resources would be a large undertaking, but we believe that it can be done incrementally, with useful results at each stage. Early versions will stop decomposing the object structure of resources at a fairly high level, leaving the developer to handle the data structures native to the resources at the leaves of the forest. There should still be a substantial benefit in uniform access to higher level strucures.
