bgcict.acad.bg>Treebanks and Linguistic Theories 2002 20th and 21st September 2002, Sozopol, Bulgaria Workshop motivation and aims Treebanks are a language resource that provides annotations of natural languages at various levels of structure: at the word level, the phrase level, the sentence level, and sometimes also at the level of function-argument structure. Treebanks have become crucially important for the development of data-driven approaches to natural language processing, human language technologies, grammar extraction and linguistic research in general. There are a number of on-going projects on compilation of representative treebanks for languages that still lack them (Spanish, Bulgarian, Portugese,Turkish) and a number of on-going projects on compilation of treebanks for specific purposes for languages that already have them (English). The practices of building syntactically processed corpora have proved that aiming at more detailed description of the data becomes more and more theory-dependent (Prague Dependency Treebank and other dependency-based treebanks as the Italian treebank (TUT) or the Turkish treebank (METU); Verbmobil HPSG Treebanks, Polish HPSG Treebank, Bulgarian HPSG-based Treebank etc.). Therefore the development of treebanks and formal linguistic theories need to be more tightly connected in order to ensure the necessary information flow between them. The workshop aims at being a forum for researchers and advanced students working in one or both of these areas. It will be held in conjunction with the summer school "Empirical Linguistics and Natural Language Processing", Flagman hotel, Sozopol, Bulgaria. Topics of interest Papers should address the following topics: - design principles and annotation schemes for treebanks; - applications of treebanks in acquiring linguistic knowledge and NLP; - the role of the linguistic theories in a treebank development; - treebanks as a base for linguistic research; - evaluation of treebanks; - tools for creation and management of treebanks; - standards for treebanks. Two round-table discussions will be organized on the following topics: - the relationship between the syntactic properties of a given language and the choice of linguistic theory for annotation purposes - the utility of treebanks for linguistic theorizing Important dates Deadline for workshop abstract submission 12th April 2002 Notification of acceptance 20th May 2002 Final version of paper for workshop proceedings 24th June 2002 Submissions Papers should describe existing research connected to the topics of the workshop. The presentation at the workshop will be 25 minutes long (20 minutes for presentation and 5 minutes for questions and discussion). Each submission should include: title; author(s); affiliation(s); and contact author's e-mail address, postal address, telephone and fax numbers. Extended abstracts (maximum 1500 words, plain-text format or Postscript) should be sent to: Name: Kiril Simov Email: kivsMail to author|Respond to list|Read more issues|LINGUIST home page|Top of issue
ims.uni-stuttgart.de>2nd Announcement (we apologize if you receive this message more than once) *** International CLASS Workshop *** on Natural, Intelligent and Effective Interaction in Multimodal Dialogue Systems Copenhagen, Denmark 28-29 June 2002 Detailed and more up to date information may be found at the workshop webpage: http://www.class-tech.org/events/NMI_workshop2.html Invited Speakers/Contributors (nearly all confirmed): Tim Bickmore and Justine Cassell (MIT Media Lab), Phil Cohen (Oregon Graduate Institute), Ronald Cole (University of Colorado at Boulder), Bjoern Granstroem (KTH, Stockholm), Dominic Massaro (UCSC), Candy Sidner (MERL, Cambridge, MA), Oliviero Stock (ITC-IRST), Wolfgang Wahlster (DFKI), Yorick Wilks (University of Sheffield), GENERAL DESCRIPTION Following up on the CLASS workshop in Verona (Italy, 14-15 December 2001), this workshop will concentrate on innovative and challenging approaches on natural, intelligent and effective interaction in multimodal dialogue systems. The aim of the workshop is to bring together theoretically and practically oriented researchers from both academia and industry with the purpose of having a thorough, fruitful and representative discussion of the topic area in an international setting. CLASS SPONSORSHIP The workshop is sponsored by the European CLASS project (http://www.class-tech.org/) which was initiated on the request of the European Commission with the purpose of supporting and stimulating collaboration within and among Human Language Technology (HLT) projects, as well as between HLT projects and relevant projects outside Europe. Currently, CLASS comprises 42 projects and 220 registered members. TOPICS OF INTEREST We welcome papers describing theoretical or practical research on multimodal dialogue systems. The focus of the workshop is on natural, intelligent and effective multimodal interaction. Topics of interest include: * Multimodal Signal Processing Models for multimodal signal recognition and synthesis, including combinations of speech (emotional speech and meaningful intonation for speech), text, graphics, music, gesture, face and facial expression, and (embodied) animated or anthropomorphic conversational agents. * Multimodal Communication Management Dialogue management models for mixed initiative conversational and user-adaptive natural and multimodal interaction, including models for collaboration and multi- party conversation. * Multimodal Miscommunication Management Multimodal strategies for handling or preventing miscommunication, in particular multimodal repair and correction strategies, clarification strategies for ambiguous or conflicting multimodal information, and multimodal grounding and feedback strategies. * Multimodal Interpretation and Response Planning Interpretation and response planning on the basis of multimodal dialogue context, including (context-semantic) models for the common representation of multimodal content, as well as innovative concepts/technologies on the relation between multimodal interpretation and generation. * Reasoning in Intelligent Multimodal Dialogue Systems Non-monotonic reasoning techniques required for intelligent interaction in various types of multimodal dialogue systems, including techniques needed for multimodal input interpretation, for reasoning about the user(s), and for the coordination and integration of multimodal input and output. * Choice and Coordination of Media and Modalities Diagnostic tools and technologies for choosing the appropriate media and input and output modalities for the application and task under consideration, as well as theories and technologies for natural and effective multimodal response presentation. * Multimodal Corpora, Tools and Schemes Training corpora, testsuites and benchmarks for multimodal dialogue systems, including corpus tools and schemes for multilevel and multimodal coding and annotation. * Architectures for Multimodal Dialogue Systems New architectures for multimodal interpretation and response planning, including issues of reusability and portability, as well as architectures for the next generation of multi-party conversational interfaces to distributed information. * Evaluation of Multimodal Dialogue Systems Current practice and problematic issues in the standardization of subjective and objective multimodal evaluation metrics, including evaluation models allowing for adequate task fulfilment measurements, comparative judgements across different domain tasks, as well as models showing how evaluation translates into targeted, component-wise improvements of systems and aspects. WORKSHOP FORMAT Although the workshop has an open character implying that plenty of room is available for the presentation of papers from researchers from all over the world, the workshop will contain invited contributions from a group of 10 specially qualified researchers with a balanced composition of workshop-relevant expertise. Part of the group is selected from the broad CLASS community; part of them are internationally leading researchers from outside CLASS. Invited contributors will also participate in the panel session organized by the co-chairs of the workshop program committee. SUBMISSION OF FULL AND SHORT PAPERS In addition to papers for full plenary presentation, we encourage the submission of short papers in combination with a very short presentation in the plenary session followed by a poster presentation. Full papers must be no longer than 10 pages, including references, examples, algorithms, graphical representations, etc. Short papers should be 4 pages maximally. Full and short papers should be sent electronically to the e-mail address classworkshop2002Mail to author|Respond to list|Read more issues|LINGUIST home page|Top of issue
