HLT-NAACL 2003 combines the HLT and NAACL (North American Chapter of the Association for Computational Linguistics) conference series. As an experiment in reducing "conference overload", the organizers of HLT and the NAACL Executive agreed to combined conference in 2003. Thus the conference provides a unified forum for researchers across a spectrum of disciplines to present recent, high-quality, cutting-edge work, to exchange ideas, and to explore emerging new research directions.

The conference especially encourages submissions that discuss synergistic combinations of language technologies (e.g., Speech with Information Retrieval, Machine Translation with Speech, Question Answering with Natural Language Processing, etc.).

The conference will give special consideration to papers that address a special topic: New approaches to and uses of unsupervised and lightly supervised learning techniques.

The conference organization is overseen by a board representing the North American Chapter of the Association for Computational Linguistics (NAACL), SIGIR, the International Speech Communication Association (ISCA), and HLT funding agencies in North America.


Full papers are due on December 30, 2002, at 5pm your local time.


The conference addresses advances in all aspects of human language processing. Topics of interest include computational approaches to:

  • Speech processing, including:
    • Speech recognition
    • Speech generation
  • Rich transcription: automatic annotation of information structure and sources in speech
  • Text summarization
  • Question answering
  • Computational analysis of phonology, morphology, syntax, semantics, pragmatics, discourse, style
  • Statistical techniques for language processing, including
    • Corpus-based language modeling
    • Lexical and knowledge acquisition
  • Language generation and text planning
  • Sentence parsing and discourse analysis
  • Multilingual processing, including
    • Machine translation of speech and text
    • Cross-language information retrieval
    • Multi-lingual speech recognition and language identification
  • Evaluation, including
    • Glass-box evaluation of HLT systems and system components
    • Back-box evaluation of HLT systems in application settings
  • Development of language resources, including
    • Lexicons and ontologies
    • Treebanks, proposition banks, and frame banks
  • Understanding of human communication, including
    • Natural language interfaces
    • Dialogue structure and dialogue systems
    • Message and narrative understanding systems
  • Information extraction from multiple media
  • Information retrieval


    Full papers will be evaluated in a blind review process, as with previous NAACL conferences. Short papers will be evaluated in a separate reviewing process. Work cannot be submitted both as a full paper and as a short paper or poster. However, the Program Committee may recommend that a full paper be converted to a short paper or a poster (the authors are free to decline this offer).

    Two volumes of proceedings will be produced; one for full papers and a another for short papers (late-breaking results), posters, and demonstration descriptions.


    Requirements: Submissions must describe original, completed, unpublished work, and include concrete evaluation results when appropriate. Papers that have been or will be submitted to other meetings or publications must provide this information (see submission format); in the event of multiple acceptances, authors are requested to immediately notify the program chairs and choose which meeting to present and publish the work at as soon as possible -- HLT-NAACL 2003 cannot accept for publication or presentation work that will be (or has been) published elsewhere.

    Format: Submissions must be electronic and in PDF, should follow the two-column format of ACL proceedings and should not exceed eight (8) pages, including references. Authors are strongly encouraged to use the LaTeX style files or MSWord equivalents available on the website -- these formats will ease the transition to the proceedings version.

    Reviewing: Reviewing will be blind. No information identifying the authors should be in the paper: this includes not only the authors' names and affilations, but also self-references that reveal authors' identities; for example, "We have previously shown (Smith 1999)" should be changed to "Smith (1999) has previously shown". A separate identification page is required.

    Procedure: All interactions will be done via the website and email.

    A PDF file of the paper must be uploaded onto the system by the date of the announced deadline. In addition, information about each paper must be entered on the website. This information will include:

    • Paper title
    • Authors' names, affiliations, and email addresses
    • Contact author
    • A short list of keywords (selected from a predefined list)
    • Abstract (no more than 500 words)
    • Whether or not the paper addresses the special topic of unsupervised learning
    • Whether or not the paper is under consideration for other conferences

    Authors who for some reason cannot submit a PDF file electronically should contact the program chairs in advance of the due date to work out alternate arrangements.
