____________________________________________________________________________ Announcement 4th SIGdial Workshop on Discourse and Dialogue Sapporo, July 5 and 6, 2003 (immediately preceding the 41st annual meeting of the ACL) ____________________________________________________________________________ Continuing with a series of successful workshops in Hong Kong, Aalborg and Philadelphia, this workshop spans the ACL and ISCA SIGdial interest area of discourse and dialogue. This series provides a regular forum for the presentation of research in this area to both the larger SIGdial community as well as researchers outside this community. The workshop is organized by SIGdial, which is sponsored jointly by ACL and ISCA. TOPICS OF INTEREST We welcome formal, corpus-based, implementational and analytical work on discourse and dialogue, with a focus on the following three themes: (1) Dialogue Systems Spoken, multi-modal, and text/web based dialogue systems including topics such as: * Dialogue management models (specific sub-problems or general modeling, in particular models for mixed initiative and user-adaptive dialogue); * Speech and gesture, text and graphics integration (for understanding or generation); * Context-based interpretation of dialogues and/or response planning, in particular how this contributes to natural interaction; * Strategies for preventing, detecting or handling miscommunication (repair and correction types, clarification and under-specificity, grounding and feedback strategies); * Utilizing prosodic information for understanding and for disambiguation; * Contrasts between task-driven and conversational dialogue. (2) Corpora, Tools and Methodology Corpus-based work on discourse and spoken, text-based and multi-modal dialogue including its support, in particular: * Issues and problems in discourse and dialogue annotation; * Annotation tools and coding schemes; * Data resources for discourse and dialogue studies; * Corpus-based techniques and analysis (including machine learning); * Tools (XML-based and other) for dialogue system building; * Evaluation of dialogue systems, including methodology, metrics and case studies. (3) Pragmatic and/or Semantic Modeling The pragmatics and/or semantics of discourse and dialogue (i.e., beyond a single sentence) including the following issues: * The semantics/pragmatics of dialogue acts (including those which are less studied in the semantics/pragmatics framework); * Incremental (plan-based, topic-based, etc.) models of discourse/dialogue structure integrating referential and relational structure; * Modeling genre-specific aspects of discourse and dialogue structure, including the specific structural aspects of (interactive) digital media; * Prosody in discourse and dialogue; * Modeling politeness and non-recursive parts of discourse and dialogue; * Models of presupposition and accommodation; operational models of conversational implicature. SUBMISSION OF PAPERS AND ABSTRACTS The program committee welcomes the submission of long papers for full plenary presentation as well as short papers and demonstrations. Short papers and demo descriptions will be featured in short plenary presentations, followed by posters and demonstrations. * Long papers must be no longer than 10 pages, including title page, examples, references, etc. In addition to this, two additional pages are allowed as an appendix which may include extended example discourses or dialogues, algorithms, graphical representations, etc. * Short papers and demo descriptions should aim to be 5 pages or less (including title page, examples, references, etc.) Authors are encouraged to make illustrative materials available, on the web or otherwise. For example, excerpts of recorded conversations, recordings of human-computer dialogues, interfaces to working systems, etc. Both long papers and short papers should be sent electronically to the e-mail address: sigdial2003@cs.cmu.edu and must be received no later than March 27th. The format to use for papers and abstracts is the same (and is the 2003 ACL final paper format). Style files and additional instructions are available at http://www.speech.cs.cmu.edu/sigdial2003/templates/ Papers must be submitted in pdf format. The title page (no separate title page is needed) should include the following information: Title: Authors' names, affiliations, and email addresses; Keywords; Abstract (short summary up to 5 lines); IMPORTANT DATES Submission March 27, 2003 Notification April 28, 2003 Final submissions May 23, 2003 Workshop July 5-6, 2003 WEBSITES Workshop website: http://www.speech.cs.cmu.edu/sigdial2003/ Sigdial website: http://www.sigdial.org/ ACL website: http://www.ec-inc.co.jp/ACL2003/ WORKSHOP PUBLICATIONS All accepted papers will be published in the workshop proceedings and will subsequently be available on the SIGdial web site.
