_____________________________________________________________________________ 3rd SIGdial Workshop on Discourse and Dialogue Philadelphia, Pennsylvania, July 11 and 12, 2002 (Just following the 40th Anniversary ACL) _____________________________________________________________________________ Continuing with a series of successful workshops in Hong Kong and Denmark, this workshop will span the ACL and ICSA 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 communicty. The workshop is organized by SIGdial, which is sponsored jointly by ACL and ICSA. 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 subproblems or general modeling, in particular models for mixed initiative and user-adaptive dialogue); speech, text, and graphics integration (for understanding or generation); contextual interpretation of dialogues and/or response planning, in particular how this contributes to natural interaction; strategies for handling or preventing miscommuncation (repair and correction types, clarification and underspecificity, grounding and feedback strategies); utilizing prosodic information for various types of disambiguation; task-driven versus conversational dialogue; evaluation of dialogue systems including task complexity measurements. (2)Corpora and Corpus Tools 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; techniques (including machine learning), tools, coding schemes and data resources for discourse and dialogue studies; XML-based tools for dialogue access to internet information. (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. Workshop Format The workshop will include a few plenary presentations of general interest followed by thematic sessions. The thematic sessions will combine long presentations, short presentations, and demos (as appropriate) with extended discussions. Highlights of the thematic sessions will be presented in a closing session. In addition, all participants who request space may present a poster in separate session. Three thematic sessions are planned: Annotation Methods for Corpora Architectures for Dialog Systems: Agent-based vs. Pipelined Learning and Adaptivity in Dialog Systems Submission of Papers and Abstracts The program committee welcomes the submission of long papers describing theoretical contributions as well as short papers describing ideas or project implementations. 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 should aim to be 4 pages or less (including title page, examples, references, etc.) Both long papers and short papers should be sent electronically to the e-mail address: sigdial2002@uiah.fi and must be received no later than March 15. The format to use for papers and abstracts is the same (ACL final paper format). Stylefiles are available at http://www.cs.ualberta.ca/~lindek/acl02/style/. 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; Preferred thematic session, if any. Abstract (short summary up to 5 lines); Important Dates Submission March 15 Notification April 29 Final submissions May 17 Workshop July 11 - 12 Websites Workshop website: http://www.mlab.uiah.fi/~kjokinen/sigdial/ Sigdial website: http://www.sigdial.org/ ACL website: http://www.acl02.org Workshop Publications All accepted papers will be published in the workshop proceedings.
